Mold Testing
in Leander

Mold Testing & Indoor Air Quality Inspections

Leander continues to experience rapid residential and commercial growth. Even in newer properties, moisture problems can develop from leaks, humidity, or construction defects, creating conditions where mold can grow if left unaddressed.

We offer professional mold testing to detect hidden growth, determine the source, and provide clear next-step recommendations.

What We Test For

In humid regions with frequent storms and ongoing development, moisture issues can develop quietly and worsen over time. We help homeowners, property managers, and real estate professionals identify environmental and indoor air quality concerns early to prevent costly damage and protect property health.

We offer:

Mold testing and inspections
Indoor air quality assessments
Moisture and leak detection investigations
Post-remediation clearance testing
Allergen and contamination evaluations

Common Mold & Moisture Issues in Homes

Mold growth is often caused by hidden moisture from roof leaks, plumbing issues, HVAC condensation, storm water intrusion, or poor ventilation. Since it can develop behind walls, under flooring, and in ductwork, it may go unnoticed for long periods. Many property owners first notice problems through musty odors, stains, or reduced indoor air quality.

Our inspections can help you:

Detect hidden mold growth
Identify moisture issues before structural damage occurs
Improve indoor air quality
Support real estate inspections and transactions
Confirm successful remediation after cleanup

Trusted Local Experts

We focus on providing accurate results, clear communication, and prompt service. Our easy-to-understand reports give you the information and confidence needed to make informed decisions about your property.

We work with:

Homeowners
Property managers
Real estate agents
Commercial property owners

Howard environmental was very professional, effective, well communicative, and fairly priced. Grateful to have them complete our work.

Thoroughly recommend Howard Environmental for mold testing, and if you have used someone else, and are faced with your bank account about to be drained and house about to be near demolished on an extreme mold remediation protocol - they should be a necessary second opinion. Having a highly competent, communicative, reasonable mold assessment team could not be more critical. We had them out for a second opinion assessment (they were recommended by our HOA) and their recommendations saved us 10s of thousands on protocol remediation. Whenever we ultimately move and are shopping for a new home, I would 1000% have them test a future home within our option period. This team is worth their weight in gold - recommend William and Landon's work 1000 times over.

The guys at Howard Environmental are by far the most professional and thorough mold inspection company around. From the initial phone call with Will, to pre-inspection, remediation protocol, and post inspection with Landon, and report explanations with Cary I experienced nothing but professionalism and quality work. Will, Landon, Cary were extremely knowledgeable, informative and efficient at their jobs and I would highly recommend them to anyone in need of a mold inspection. Thanks for all your help guys!

Honestly, I can't recommend William enough. He accommodated my request and came out faster than anyone else could. I reached out during a super stressful time and he got back to me quickly, even days later when I had more questions. He never once made me feel like a bother. William is clearly an expert but actually took the time to break everything down so I understood it (unique to my situation), instead of just firing off a report. Super honest, super thorough, and genuinely a good dude to deal with when you're stressed out of your freaking mind. If you need a mold assessment, just call him. You won't regret it.

Howard Environmental stepped in and provided excellent service relevant to Mold inspection and protocols associated with Black Mold. Will and Landon were both professional and technically proficient. I would highly recommend their service if you encounter Black Mold and need a Mold inspection.

I can’t say enough good things about Cary and Howard Environmental. What a company with integrity. Even though my needs were outside the company’s focus, he was so generous with his time in trying to refer me to the right company for my unique situation as well as talking to me about my situation and lending his insight and knowledge. I really respect people who move through the world this way with such generosity of spirit and wanting to make sure people land in the right place, especially when dealing with difficult situations.

I had preliminary questions about a mitigation/restoration project after a water leak. Mr. Howard walked me through this process over the phone and I am very appreciate that he was willing to share his knowledge and expertise without any promise getting work done.

I reached out to Howard Environmental about a possible mold issue not realizing they did not service the area I live in. The person I spoke with, William, was willing to take the time to look at photos I provided knowing I would not be a potential customer. Great follow up and quick to respond. He offered his expert opinion and followed up with a plan of action just in case. I would highly recommend Howard Environmental.

I contacted Howard on a whim and spoke to William — I must say, these guys are good natured, honest, and lead with expertise over making a quick buck when it is not necessary. I am pregnant, due in 4 months, and noticed some concern area on our limestone right where our nursery is about to be. William offered to educate me first, he calmed my alarm bells, and then took the time to look at pictures and assess. He relayed confidence opinion this was not a mold issue on the inside, and something to be treated via pressure wash. After doing further research too it does seem to be the case. Thank you William for your honesty and time! In this area of business I could see people being taken advantage of due to how urgent/serious this could be + lack of knowledge on what it is and what to do. However I feel safe with these guys and want to relay this is a good decision to get honest opinion.

Howard Environmental was so helpful and proactive in addressing a possible mold concern after a water heater leak at my property. After Cary's guidance and additional review, I did not have a mold issue. Cary went above and beyond to help me know my next steps. In the end, I did not need to hire Cary's firm. I was so glad to learn about Howard Environmental. Thank you, Cary, for being so professional and generous with your time! Highly recommend Howard Environmental!

They can't find my post, but they texted me multiples times after I left this review. Seems like within the last few days additional 1 star reviews have been left. I just want to reiterate: I was charged for two different sets of samples and I still have mold. They messaged me asking what went wrong.

I wouldn’t recommend. There is too much opacity with this company. I still have mold after following all recommendations, protocols, procedures including doing two rounds of sampling and testing and scrubbing. It cost me over $4K they worked with Allnation who I also absolutely do not recommend.

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.

I would definitely recommend hiring Howard Environmental!

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.

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.

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 🙃

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.

You can tell they are very knowledgeable about what they do and want to truly help people. I’d absolutely recommend working with them!

I would highly recommend this LOCAL company for all your mold inspection and testing needs. Thank you!!

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.

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.

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.

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!

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 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.

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.

He helped us understand each step, and was consistently communicating with us throughout the entire process. I would highly recommend his services to anyone without hesitation. This is a service you can trust.

I was concerned about mold in my apartment and the level of service and attention that I got from William was incredible. I found this through chatgpt search and it led me to the best in Austin. Highly recommend.

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.

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. For us the mold testing fee was worth the peace of mind. We can trust that the investments we are making in fixing the problems are the necessary ones.

These people are the best. I got really excellent and honest advice from them about a mold issue that was wreaking havoc on my health. I've been so happy to refer other people to them because I have come across some folks in the industry that are not as honest.

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.

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 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.
