"This business owner is very intelligent and knows his business. His wife is a fantastic person. He would educate me along the way about the airflow process and what could create mold. We're not so sure it's mold rather the water that's bad but I still look forward to getting his test results to see if he was able to capture exactly what elements are in the air affecting my health."

"I had mold under my refrigerators and I had called several companies, and they all quoted me these ridiculously high prices . I got the call from Joel Fallas and he came over here within an hour. He was so quick. He looked at the problem, I said I was going to pay you for this, and told me what to do to get rid of the mold. I tried to pay him and he said no. He said I will not take your money. I did what he told me to do and I got rid of the mold, and he called me later that day to see how it works and make sure if I was happy,, and I said yes. I just what to tell how honest this man."

"Mold Test Company makes a point of not themselves providing mold remediation services, so theoretically they don't have an incentive to find mold. In my case, they did, and immediately recommended their partner Biocide Labs for remediation products. They were even able to transfer me directly to Biocide, whose representative then recommended a high-priced do-it-yourself kit. While the products recommended seem effective, I chose to have my ducts professionally cleaned. Mold Test Company provided lab results of their testing but could not tell me where their sample were taken, and they did not provide photos of actual mold in my house."

"The inspection went very well and the inspector was very knowledgeable and professional. The inspection uncovered an ongoing problem we were having in a section of our home. The inspector explained the process on how the inspection would be carried out, types and cases of mold, and remediation steps. He was timely, dressed in protective gear and was very careful in our home. The test results we’re back as scheduled and he went through the report with us to ensure we understood the results. Thanks for a professional job well done and for locating and solving our issue."

"I would definitely recommend using All Dry USA for any water restoration and/or mold remediation. They did an amazing job in a timely manner. Their team was amazing and professional. A major thanks to Allan, Adrian, Victor, Gerardo and Jose. Also, Mr. Rodriguez as he was my first point of contact!"

"We are selling our home and the new home owners and their insurance required a mold certificate since our home flooded during Harvey. we worked with reputable contractor and they remediated. We called another company prior to him and she told me that since we had already completed the rebuild, we would very likely fail. And she would refer me to a company they work with to help us remediate. and then after tarping and holes in the wall, they would come back out (pay again) and then we would probably pass...it didn't pass my smell test. This company was professional and very nice. He explained the entire process to us, without causing ANY anxiety or telling us we would probably fail. He did the testing and 48 hours later, we received an email passing. This process should not be another Harvey related stressor. Thank you to Mold Inspection Houston it was not! Thank you Mold Inspection Houston."

"The Inspector was great, but They only inspect for Mold and send to lab for results. They do not remediate, and they charge extra to provide a remediation directive/recommendation to have mold cleaned up or removed, dissappointing."

FAQs for mold & toxic material test projects in Sugar Land, TX

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
