Mold Testing
in Leander

Professional Mold Testing Services in Leander

Leander is one of the fastest-growing areas in Central Texas, with new homes and developments expanding rapidly. While newer construction offers many benefits, it can also introduce hidden moisture issues that lead to mold growth if not properly managed.

From newly built homes to expanding neighborhoods, moisture can become trapped inside walls, attics, or HVAC systems, often without visible signs. At Howard Environmental, we provide professional mold testing in Leander to detect hidden mold, identify the source, and give you clear, actionable next steps.

Why Homeowners in Leander Choose Howard Environmental?

When it comes to mold testing, local experience and accuracy matter, especially in fast-growing communities.

Experience with New Construction Homes: We understand the risks associated with rapid development, including moisture trapped during the building process.

Advanced Detection Methods: We use moisture meters, infrared thermal imaging, and targeted air and surface sampling to uncover mold that isn’t visible.

Root Cause Identification: We don’t stop at detection. We identify what’s causing the mold, whether it’s a leak, HVAC issue, or humidity imbalance.

Fast, Reliable Results: Most lab results are available the next business day so that you can move forward quickly.

Clear, Actionable Reports: You’ll receive a detailed report with photos, findings, and straightforward recommendations you can use immediately.

Common Mold Problems in Leander Homes

Mold issues in Leander are often tied to rapid development and environmental conditions.

New Construction Moisture Trapping: Fast build timelines can sometimes result in moisture being sealed inside walls before materials fully dry.

HVAC and Condensation Issues: Frequent AC use can create condensation buildup in ducts and vents.

Expanding Infrastructure & Drainage: New developments may experience drainage challenges that lead to moisture intrusion.

Attic Ventilation Problems: Improper ventilation can trap heat and humidity, creating ideal conditions for mold.

Humidity and Climate: Central Texas humidity continues to be a major contributor to mold growth indoors.

When Should You Get Mold Testing?

You should consider professional mold testing in Leander if:

You notice a musty or persistent odor
You’ve had recent water damage or leaks
You see discoloration on walls or ceilings
You’re experiencing unexplained allergy symptoms indoors
You’re buying or selling a home and want to ensure air quality

I worked with Howard Environmental to remediate a mold issue in my rental home. William and Cary run the show and are always helpful and available. They know what they are doing, and make it easy to get the project off the ground and finished quickly. No one looks forward to working on a mold issue, but they make it as simple as possible and they do what they say they're going to do. I would definitely recommend.

Microbial growth situations are a huge headache, but I’m grateful for the team at Howard Environmental: Landon, Will, and Cary who graciously cared for my family and I throughout this entire process. They educated us on what to expect and we’re very easy to work with. They also answered all of our questions and fit us into their busy schedule all the while remaining very professional.Thank you, Landon, Will, and Cary for all of your help. We hope we never have to go through this again, but if we do we know who to call.

Have had an incredible experience with Howard Environmental. I have interacted with William and Landon. Both were extremely knowledgable about any situation a homeowner could be in. Walked me through what steps to expect, were consistent and thorough in their approach, were strategic and honest with the priority list, and were also responsive.5 star experience all around.

Andrew Burns

Overall, my experience with Howard Environmental was great! Cary was able to answer all my questions and concerns that I had before hiring them as my mold inspector. Landon was my local guy that preformed the actual inspection and he exceeded my expectations. Landon was very transparent, thorough and also answered all my questions and concerns. I would definitely recommend hiring Howard Environmental!

Todd Hawes

11:46 18 Apr 26

The testing done by William and Landon was done extremely quickly and William took the time to explain the report completely and where to find state documents to read about options I have for remediation as I live in an apartment. High quality work with professionalism and speed. The whole process was done in 48 hours.

William was professional and courteous, he respected our home and educated us in the process. He was thorough with his inspection, and protocols on how to remediate the situation. I highly recommend doing business with Howard Environmental, William made us feel comfortable and we had total trust in his knowledge and experience 100%.

Howard Environmental is the most professional, knowledgeable, patient mold inspection and testing company. They walked with me, step-by-step, through the entire process. They didn't try to scare or upsell me, but they kindly and patiently supported me through what was happening and provided measured, professional guidance. They remained available for follow up questions and never once made me feel badly for being nervous or asking too many questions. I've worked with other companies, and never experienced this level of professionalism and care. They are truly the best in the industry.

I would 1000% recommend the entire Howard Environmental team to both friends and family! I called about a mold problem in our office and spoke with William who gave me the low-down on our options. He was very clear on the process, our inspection options, and next steps. William knows his stuff! From Texas law to types of molds to just being a well-spoken person. Landon came out to do the physical assessment and sample. He was also knowledgeable and was able to point out things we hadn't noticed as renters, like the discoloring of the wooden floor. As a woman, I felt comfortable having Landon as an inspector. We received out results within a few days and I called William for a translation. We spoke for 45 minutes – he clearly has a genuine goal of helping people.

I can’t say enough good things about William Rivers at Howard Environmental. He is so friendly, patient, knowledgeable, informative, polite and respectful. We will be customers for life! Highly recommend this company and their fantastic consultant. Thanks for reading and hope this helps someone else with their decision making.

These folks are amazing. William came and not only did thorough testing, he educated us on everything related to mold in your home and remediation. He also spotted a mold area in our kitchen immediately after arriving. He is such a plethora of knowledge. His advice on our issues helped us get our insurance company to help with remodeling costs for our kitchen and bathroom. We are forever grateful for this company and their incredibly educated staff. I would recommend them to anyone who has mold concerns, no matter how small.

20:16 09 Mar 26

Excellent service. Cary/Howard took the time to go over each and every question we had before we even decided to go with them. Landon came on time and did an extensive inspection and found areas needing remediation. The lab and comprehensive report came the next day. Highly recommend this company.

Will and his team have the kind of integrity that is hard to find in this industry, and many these days. He came to do a mold inspection for us October 2025 at the start of my pregnancy and he was so transparent, honest and beyond fair in his approach. He didn’t try to sell us tests we didn’t need - in fact, he basically said no mold seemed present despite a smell that was coming from water buildup underneath our tub and he charged us half of his in-home visit fee.I was just blown away by how much he cares about doing the right thing and I can’t recommend his team enough!Thank you Will and sorry for the delay with my review! Pregnancy brain is real 🙃

Paige Brady

15:53 21 Feb 26

I highly recommend Howard Environmental. William and Cary were extremely helpful and supportive throughout the process. William conducted a very thorough visual inspection and only tested in a few suspect places. Other inspectors can run up the cost by testing unnecessarily. He provided many helpful tips and advice along the way. He was very considerate of our needs as home owners.

Courtney Marie

15:56 13 Feb 26

After speaking with several companies, I’m so glad we chose Will and his team. From the first discovery call, Cary was kind, patient, and very clear about what to expect. The inspection, report and recommended protocol were all extremely thorough and we really appreciated how much time he took to walk us through everything and answer our questions so we fully understood what was found and how to address it. You can tell they are very knowledgeable about what they do and want to truly help people. I’d absolutely recommend working with them!

Joseph Segura-Conn

15:11 29 Jan 26

William was extremely professional and helpful throughout the process. He took the time to review our mold findings in detail, explained what they actually meant, and provided clear, practical guidance on next steps to ensure our home is safe for our family. We really appreciated his knowledgeable approach and honest assessment. We would highly recommend him to others and would absolutely reach out again if any concerns come up in the future.

While we did not decide to go through with this company due to our urgent situation needing a next day appointment, Howard Environmental was extremely nice and listened to my concerns and provided great information and was very flexible and understanding when we had to cancel our appointment (that they were able to squeeze us in for 2 days out which was awesome!) and find sooner availability. I would highly recommend this LOCAL company for all your mold inspection and testing needs. Thank you!!

Nina

23:00 03 Dec 25

Cary from Howard Environmental was extremely nice and knowledgeable! He offered to listen to my concerns about a mold remediation that was done and provided his opinion free of charge! Even when I tried to offer him money for his time, he simply said that he was happy to help and that I don't need to pay him. I appreciate his assistance and would recommend for anyone needing mold testing to go with these guys! Very nice people 🙂

I have had the opportunity to work with William on 2 different occasions and both times he was nothing short of outstanding. William guides you on what needs to be done and what doesn't need to be done i.e. there is 0 upselling. While William guided me on the house inspection, Cary helped me better understand the report. I have researched a lot of mold inspectors and it's my humble opinion that Howard environmental is the best mold inspection company in Austin, Texas and quite possibly the best mold inspection company in the state of Texas.

Sara Smithhart

22:23 17 Nov 25

Howard Environmental is truly top-notch. William and Kary are incredibly knowledgeable about all things mold and take the time to explain the ins and outs in a way that homeowners—and agents—can actually understand. I’m a real estate broker in Austin, and they’ve now helped me on two of my listings.On both homes, a pre-MLS inspection showed signs of possible growth. William came out quickly, performed thorough testing, and provided clear, detailed reports. Their guidance helped reassure potential buyers that the growth was not black mold and that the levels inside the home were not toxic.Their professionalism, prompt communication, and expertise make them an absolute asset in any real estate transaction. I highly recommend Howard Environmental to anyone needing mold testing, peace of mind, and trusted experts in their corner.

Kay Knippa

16:36 12 Nov 25

I recently spoke with Cary Kraft at Howard Environmental regarding a very small bathroom mold issue. He very kindly shared his expertise and helped me formulate a plan to resolve the situation. Cary was very knowledgeable and helpful. I highly recommend Howard Environmental and Cary Kraft and will use their professional services in the future should need arise.

Michael Hobbs

21:19 10 Nov 25

We had a great experience working with William. His communication was fantastic and he helped us effectively navigate a few curve balls along the way. We’d definitely recommend!

We sent our mold test results from another company to William at Howard Environmental for a second opinion. The company that did our mold testing advised that based on the results we needed to move out immediately due to the type and level of the mold, and of course they offered their expensive remediation and litigation support services. William gave us a detailed and thorough analysis of our lab results which indicated that we had nothing more than ordinary levels and types of mold in our house. He even had his partner give us a third opinion verifying the same. Needless to say we are not having to move out or engage in any expensive remediations or lawsuits. So grateful for the team at Howard Environmental for their expertise, honesty, integrity and concern. Highly recommend this professional, experienced team who empathize greatly with people facing the unknown health and financial threats when it comes to mold. You really need someone like them you can trust. This second (and third) opinion saved us from a disastrous situation for our family.

Choosing a mold consultant is always a difficult process. You never know if you're going to get someone who is just trying to scare you into overpaying. Howard Environmental on the other hand gave us in-depth, factual information every step of the way. William was a mold remediation consultant who started doing inspections after seeing first hand how others were just screwing people over. He was extremely helpful every step of the way and I highly recommend Howard Environmental if you're concerned about mold.

This is my second review in my life ever written. Thank you Howard for being honest.. and straightforward. I was referred by All Nation Restoration for your services... and you have been a godsend. Thank you for honesty and awesome communication with the team at all nations... I have since let all my neighborhood know, if you have any issue with mold or worry to call Howard and talk to Will, you cannot go wrong. Our family had the most honest experience with you and the restoration company and forever thankful. i wish ic ould give you 10 stars!

William was amazing!! He addressed all of our questions and concerns regarding the mold issue in our apartment. He is so knowledgeable and thorough. He really took the time to also explain and walk us through the report and provided some guidance on how to proceed after we received the results. 100% would recommend this company if you’re in the Austin area looking for a mold inspector.

Courtney Chavez

14:51 16 Oct 25

5 stars easily! William at Howard Environmental definitely knows what he’s doing. Found mold in my laundry room that I had no clue was there because it was white and very hard to see! He walked me through his entire process and didn’t rush me when I asked a bunch of questions. Friendly and thorough! This is the man you want to see if you suspect mold in your house!

5 stars and glowing review for William, the inspector who made me feel safe, reassured and prepared throughout the remediation process. He is very thorough and walks you through the reasons why the problems can arise and provides helpful preventative measures as well. He is immensely knowledgeable and feels very trustworthy. Moreover, he was flexible and came by at later times to work with my schedule—that was so appreciated!

William from Howard Environmental is the best mold inspector you will find! I have used several mold inspectors in the past and none of them come close to how good he is.I was trying to buy a 6 year old home in the Austin Area and I wanted a good mold inspector because I have had issues in the past. I searched all kinds of Reddit forms and everywhere trying to find the best and most recommended mold inspector. His name appeared the most during my research so I went with him.I called to schedule an appointment and he was booked out extremely far (because he is the best). I explained to him that I was on a time constraint due to my option period ending and he offered make room for me on his schedule and he scheduled me for the following evening. He showed up at the home around 5:30pm and stayed until almost 8:45pm. He spent hours in my home searching inch by inch from the floor to ceiling in every room. Checking not only visually but also with a moisture meter and some other fancy tools. He was able to find so many things that the home inspectors did not find. There were several windows that were not properly sealed allowing water ingress. He also found the toilet wax seal was leaking causing water to be trapped underneath the tile in the bathroom, he ended up taking an air sample of the wall behind the toilet and it came back with very high levels of mold. He also found a stove top ventilation issue in the kitchen cabinet which was causing mold growth, he took an air sample in the cabinet and it came back positive for high levels of mold. He also climbed into the attic to look around to make sure there were no mold growth issues up there, he found a lot of mold was growing in the AC system. He took pictures and documented everything. He took the air samples to a lab and had the results back to me in less then 24 hours!I am so glad I chose him because if I didn’t I would have purchased a home that not only had an active hidden water leak, but also a severe mold problem. All of these issues he found were missed by the general home inspection I had the day before.My realtor who unlocked the home for him to do the inspection stayed and watched him do the inspection. She was shocked at how detailed and thorough he was. She said that he was the most thorough mold inspector she has ever seen and took his information down to use in the future.If you want a mold inspector that actually knows what he is doing, this is your guy. If you want a mold inspector who actually cares about you, this is your guy. If you want a mold inspector that will search every inch of your home to make sure that any and all mold is found this is your guy.

William was AMAZING! He was very knowledgeable on the mold issue and explained the situation and process to me very well. He also helped detect another problem in our home concerning our HVAC system. William even helped me start my jeep! (Which he wasn’t even here for, that was not his job here today lol) Either way he was very kind, even gave some love to my pups, and I appreciated his help with everything very much! Give William a raise! He deserves it!

After our AC broke last summer, our rental company took over three months to replace it. During that time, the house became extremely humid, and ever since, I’ve been concerned about mold. When the unit was finally replaced, I actually saw visible mold inside the old system.Fast forward to this spring in Austin, with all the rain, I started experiencing daily headaches, a dry cough, and constant fatigue. I work from home, so I spend 95% of my time indoors, and it started to feel like something in the environment was off.After calling a few mold companies, we were lucky we found William. From our very first phone call, he stood out. He generously shared his knowledge, patiently answered all of my questions, and took the time to educate me, even before stepping foot in the house.When William came to inspect, he was thorough, professional, and incredibly knowledgeable. He found active mold growth in three different areas, both bathrooms and underneath the kitchen sink. He tested each one and walked me through everything in clear, simple terms: the types of mold, how they grow, and how to prevent future issues. One area I thought was dried toothpaste turned out to be fuzzy mold, I never would have known.As renters, these findings are critical to our health and next steps. William is a trusted expert, detailed in his work, and someone I wholeheartedly recommend to anyone dealing with mold or air quality concerns.

William was fantastic. He was very thorough and explained everything to me in a way I could understand. I wasn't happy with the first inspection, so hired him for a second opinion. His inspection undercovered so much more than the first report. He has been available for any questions I had, even way before I hired him. Definately recommend him!

Bella Fayad

14:40 21 Jul 25

I didn’t end up having to using Howard’s Service in my unique situation, but I would recommend him to anyone I know and will use his services if I find myself in the situation again. He spent over 30 mins with me on the phone explaining mold growth and even looked at pictures I had taken. He genuinely cares and it is extremely reassuring when you are experiencing such a stressful problem. He listens and is obviously an expert. I recommend him without any reservation

Bobbi Jo LaForce

Ashley Larson

18:00 15 Jul 25

There aren't enough positive words to speak about Howard Environmental. William went above and beyond for our mold inspection. He exhibited professionalism, knowledge, punctuality, respect, and perhaps most difficult to find nowadays: compassion. He did more than what he was required to in order to assure the health and safety of my family in our rental home. I hope to never need his services again but will be a return customer should the need arise and I recommend him to anyone.

Robert Rodriguez

22:33 11 Jul 25

Best thing I could have done was to get William to do a mold inspection for me. It not only helped me out physically but he was very informative and genuine with his approach! Now I am able to have a lot more reassurance on what my next step is! Amazing customer service and any time I needed help he was a phone call away. If he didn’t answer he would call as soon as he was available. Highly recommend!

William at Howard Environmental was incredibly helpful in addressing a mold issue in my campus apartment. From the start, he took the time to speak with me over the phone, answered all my questions, and made room in his schedule to inspect the apartment early the next morning. His responsiveness and dedication provided exactly the support I needed. I truly appreciate the time and care William put into helping me, and I would absolutely recommend his services.

Ellen Strikovski

14:39 09 Jul 25

William was amazing. As a college student who was getting neglected by my apartment complex, I was unsure of what to do when I found mold in my room but William helped us out a ton. He spent 30 minutes on the phone with us before we even booked an inspection, to explain the steps we should take and the different kinds of mold that exists. He then was able to schedule us the next morning at 7:30am, before their regular hours. He showed up on time and did a very thorough inspection. Additionally, he didn't just test the mold, he took the time to investigate the root cause of the issue which we really appreciated. William was extremely knowledgeable and answered every question we had. I had a great experience with him and would highly recommend him to anyone.

I contacted Howard Environmental to get a lead paint inspection. During my phone conversation with the owner, I learned that the company does not do lead paint inspections. However in the conversation I learned which agency probably licenses lead inspectors in Texas. The owner was very friendly and informative. He even answered some of my questions about asbestos and popcorn ceilings. Following the conversation I was able to locate 4 lead inspectors in Austin.

21:09 04 Jul 25

William came to my property after a plumbing company overflowed a toilet while testing a repair. This was following being charged over $25,000.00 by the plumbing company for repairs up to that point.It was suggested to me by the owner of the plumbing company that I choose to dry the floors and sheetrock as opposed to a tear out.The remediation company called this damage a "level three" because toilet water carries bacteria that a sink leak does not. I wanted the home restored to the condition it was in before the damage occurred, especially because I have a family member who takes a medication that leaves him immuno compromised.William arrived at my address after the tear out and the removal of fans and dehumidifiers. He listened to my concerns about contaminants and mold possibly being present. I did not want the new walls and floors installed until I knew it was safe to do so.I needed a person to trust. William heard what I said and proceeded to test every area of my concern. He explained the science, the process and when and how I would receive my results.And I did!! The results appeared in my email as promised! After living in this absolute cluster of a plumbing nightmare, William was a beacon in the storm. He was prompt, knowledgeable, patient and a man of his word.Thank you, from the bottom of my heart.

William and Justin did a great job at my apartment. The landlord did not let me out of my lease even though the apartment caused severe health issues. After I got the lab tests back, the landlord reimbursed me for the mold testing, refunded 1/2 the rent I paid since I moved in, and returned my full deposit. Also, William is very knowledgeable and patient and guided me to ensure I do not make a mistake.

Courtney Czar

21:43 06 May 25

William is very knowledgeable and personable and helped us navigate a mold issue in our ac system. With his expertise and analysis we were able to move forward with remediation with confidence in the process knowing exactly what we were confronting.

I recently had a leak from my washer and was concerned it might have caused mold. I reached out to the company, and I couldn’t be more impressed with the service. From the moment I called, they were responsive, professional, and knowledgeable. The technician arrived on time, thoroughly inspected the area, and took the time to explain what he was looking for and why. He used high-quality equipment, was respectful of my home, and answered all my questions patiently. Highly recommend this company to anyone dealing with water damage or mold concerns.

Do you want a mold inspector who is incredibly knowledgeable in the field, has invaluable experience and is able to clearly communicate that knowledge to you throughout the process? Do you want to deal with a professional at the top of their craft who is honest and treats you and your home with respect? Do you want to have a custom tailored, methodical, and conservative but thorough mold remediation plan crafted to eradicate mold… and then test to make sure every last bit of that mold is gone from your home? Then, take the first step in your process and just hire Howard Environmental, it has been the best decision we’ve made in this journey and I can’t recommend William enough.If you suspect mold in your home, you need to strategically make the first decision in your journey because everything else will pivot from that point. We’ve been removing the hidden mold in our home and Howard Environmental has been the only positive experience in our mold remediation journey. William is informative about the entire process and is a natural educator who armed us with knowledge about the remediation process and our rights as a consumer in Texas. Our experience with Howard Environmental has been invaluable and 100% positive! William not only did our inspection and formulated our remediation plan, but when our remediation contractors began making mistakes and taking shortcuts by not following the plan… William was a resource for me to call and speak to about my concerns. He offered valuable insight and supportive professional feedback to help me navigate my rights with the other company. (Sidenote: Avoid ServPro of Pflugerville as contractors!) Honestly, this review has taken me too long to write. William with Howard Environmental is the inspector that you want if you suspect mold may be in your home. Our experience with him was informative, professional, and very honest. He made a remediation plan for us that was comprehensive without being extensive in demolition and it was clear to us as the consumers how that plan should unfold. For reference we had water intrusion in our home that infiltrated two rooms with exterior walls and William was able to identify the mold circulating in our air and draft a remediation plan that was thorough without being overly invasive. Most importantly, he wrote the plan with appropriate safeguards to preserve the health of my family while we lived in the home during remediation. I cannot stress how valuable this is when you are looking at complete demolition, harsh chemical solvents, and a rebuild for sections of a home that you are still living in with small children and immunocompromised family members! William has honed his craft and if you hire Howard Environmental, then you will benefit from that finesse and experience during your mold remediation. I cannot stress what a difference that will make to your overall budget and experience. Choose well, and feel confident in your plan because nothing else about mold remediation will be easy, but your first choice can be!

William is amazing. He’s very knowledgeable and has thorough expertise as he answered every question calmed my nerves about the mold and water damage in my house. Found the source of water leak after we used several other companies and helped consult with mold remediation company. Thank you so much for your help and your continued advice. He answered all my questions even after the remediation was done!

I could not be more grateful for Justin with Howard Environmental. The process of mold/water damage/restoration is so confusing and he spent a lot of time explaining the process and what needed to be done. He delivered the information to me in a respectful and informative way where I finally understood all of it. I have never had anyone go above and beyond before and took all of my concerns seriously. I HIGHLY recommend Howard Environmental, but specifically feel very lucky for Justin's guidance and experience throughout the process. Thanks Justin!

I came across Williams website, following a google search for a solution dealing with sewerage flooding. I contacted William today, a Sunday, and was surprised by a fast response. Several emails later he had resoved my problem with his expert advice, which I will now follow to ensure my home is made safe for my family.Alun. Oxford, UK

I had mold in the house that caused many other damages. This company was always on top of everything and always answered my calls. Many of the other vendors did not. I highly recommend Howard Environmental, especially when it's imperative to have a company who knows what they are doing.

Howard Environmental is a great company to help when you have a mold issue.William Rivers was our rep. He has been on both sides of the mold remediation business over the years and that experience was invaluable. He is professional, informative, helpful and always available to bounce questions off of. He leaves you feeling like he genuinely cares about you and your situation and being as helpful as possible--a rare thing these days, but much appreciated.One example, when our insurance company declined to cover any of our issue, he put me in touch with a public insurance adjuster and it looks like our insurance company will now be paying what they should.A great company and adjuster and I highly recommend him for your issue, should you be unfortunate to have one.

I hired William after failing with a couple of other mold “specialists”. I did not feel they were being honest with me. The minute I met William I knew he was one of the good guys. He was very patient with me, answered all my questions, and was transparent (and realistic) about the situation on my hands. He had the report and lab results to me very quickly as well. I would highly recommend!

Will is fantastic! Not only is he knowledgeable, but he also takes the time to break down every detail and listen to your worries. Like many people, I think there’s always the worry that someone will come into your home and give you false information to make a small job MUCH larger than it actually is. With Will, this is not a worry! Not only are his prices incredibly affordable, but with his previous (12 years) experience in water damage, he has incredible knowledge and gives you the complete picture of what is happening in your home. Plus, he has a 24-HOUR TURN AROUND on his results!!!! I can’t say enough about my experience with Will; if you are looking for answers, I will trust Will every time!

Incredibly professional and thorough. William helped us identify sources of water damage additional to the one we knew about and helped us get in touch with a reputable remediation company. He followed up quickly, communicated well, and made sure we were happy with the whole process. Would definitely work with Howard Environmental again (event though I hope I don't have to).

I am quite thankful that we had William Rivers from Howard Environmental support us during an exhaustive and time consuming mold issue. He was actually the second consultant I had reached out to because the first gave me so little information and a remediation plan that basically tore the whole house apart. William was able to be more investigative during the inspection process and precise with his remediation plan which saved us unnecessary expenses. During the process of trying to figure out where the moisture was coming from, he was essential in the discovery and subsequent cleaning and repair. I was so appreciative that he was available for my many questions and consultations, he is truly an expert! I will always recommend William and Howard Environmental for excellent work and support through the insurance process, and remediation.

William was fantastic during our mold inspection. He was incredibly knowledgeable. He took the time to thoroughly explain everything, which I appreciated in this stressful situation of unknowns. It was nice to not feel rushed. He was quick to show up, very detailed and responsive, and upfront with his pricing-no upselling anything unnecessary either. I would absolutely use him again and recommend him to anyone (though I hope I don’t have to!)

William is someone you want as a mold resource. He is professional, knowledgeable, answers questions in layman’s terms and if he doesn’t know the answer to your question, he does not hesitate to find out and report back. His work ethic is rare for his generation. Truly, a breath of fresh air. Pun intended!

He doesn't hesitate to share his valuable knowledge and is very transparent when it comes to his process and pricing. He'll make sure that you don't pay for anything that you do not need to.

William was wonderful! He made sure to our appointment time was OUR time. He arrived promptly and was not in a rush. He took the time to explain the process as well as the purpose/goal of each test. He explained his equipment and the lab expectations, as well as provided his expertise, knowledge and experience in a way that I could understand; he explained the terminology and jargon and made sure I was comfortable and present during the inspection. William was very polite and professional! I am more than 100% satisfied with his process and quick turnaround for his findings/recommendations report and also for the lab report. I am glad we worked with William and will be sure to reach out to him if further assistance is needed in the future! Thanks William and thanks Howard Environmental LLC!

William Rivers with Howard Environmental is a topnotch professional! We needed timely and thorough work done regarding recently discovered water damage and the potential for mold. Rivers scheduled us promptly, inspected the affected areas, and carried out testing. He communicated well without being condescending, eagerly shared his professional opinion, and performed good consumer education. We later had him do follow up clearance testing after the water mitigation and mold remediation work. Rivers has got the science down, and he provides excellent customer service. I highly recommend him, and while I hope I never need him again (!), I would hire him again without hesitation.

With the help of Howard Environmental, I was able to figure out if I have mold and how harmful it might be. Mr. Rivers service was professional and friendly. Didn't take long based off the level of help i needed. Showed up on time. Was able to inform me of other physical damage happening to my apartment that I hadn't noticed. Was very informative and helpful in my fight against my apartment complex not making repairs to prevent mold. I greatly appreciate the help, i needed it.

I’d recommend 5 out of 5 times and I would use again. Great experience. Will Rivers was our inspector - Will is experienced, thorough, communicates excellently and cares about what he does. Expectations were clear, turnaround on the report was quick, the contents of the report were excellent, and Will followed up once the report was issued to answer any questions. I would trust Howard Environmental again with my home and my business.
