"I had Brett come to our home to test for mold because I’ve had an ongoing illness that Drs can never diagnose. He was so caring & did the testing within days of talking to him the 1st time. After the testing, he explained everything in detail and provided a list of things to improve the air quality in the home. I have never dealt with any type of contractor that was as thorough and really had our best interest at heart. He was honest, upfront with cost and I felt like I could totally trust him and his recommendations. If you are in need of mold or air quality testing, call Brett. You will be completely satisfied with his knowledge and care to make your home “healthy” again. "

"Our technician, David was fabulous. I have changed my review because Jeremiah was able to make things right. The company definitely stood behind their work and I would highly recommend Mold Test Company for residential or business if you are having issues with mold. Thanks Jeremiah for everything"

"This company is great to work with. They did some mold testing on parents’ home and did excellent work. They also did some work on my home. They replaced a water heater and bathroom fans. He was easy to get a hold of, personable and come over right away."

"Very affordable and thorough test results. I really appreciated that the Moldlab not only provided us with what kind of mold they found but what the affects are on people/pets and then how to get rid of the mold! Our kit was mailed on the same day we ordered it and Charlie was quick to resend my email results when I accidentally deleted them in my spam folder. "

"If you ever suspect you have toxic mold START the process with a seasoned MOLD professional, Curt.  Do not go with a generic home inspection company. <br /> I was in a situation where we were starting to cycle thru mold testing cycles - it was getting very expensive (at ~ $500 a pop) and we were not getting any guidance about where the source of the mold could be from the testing company - just that the results say there is toxic mold. <br /> Curt was able to guide me  - tell me what most likely happened, what to do / what not to do, and guide the mold remediation so we could be clear that we had cleaned up fully - so we would know if there was an additional source of mold.  As a result of his guidance - we were able to completely clean up all the mold and get out of the cycle of mold testing. <br /> In hindsight, I wish I had known about Curt and would have used him for the MOLD testing because he provided clear guidance about how to handle the situation.  I did not get this from the existing home inspection company that was doing the testing. <br /> As I had already started with an existing home inspection company, it didn't make sense to switch companies at the point we were in the process.  Curt guided me and didn't charge me for his guidance.   <br /> Curt is a true professional and knows his business. It was a pleasure to work with him. <br /> <br />"

FAQs for mold & toxic material test projects in Zion, IL

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.
