"I called to have some mold testing done on a couple of spots on our walls after finding damage from a roof leak in our home. Brett and his team did a fantastic job. They not only took wall board samples to test in the lab, but suggested air quality testing in several rooms. The wall boards had came back negative, but the air tests pointed us to an old humidifier panel being the source of my issue as I had developed an irritating cough in the months prior to calling LaFrance Environmental. I suggest you call and don’t put it off another day. Thank you Brett. I can breathe easy 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"

"Max just left my home and I already know he is the person to make our home safe! He will pack out our basement, remove mold, and remediate asbestos. I couldn’t be more happier! We are also looking for him to epoxy the floors. "

"I had Emerald Build Group come out for a mold inspection, and I’m really glad I chose them. The inspector was polite, knowledgeable, and took the time to explain everything in a way I could understand. He even pointed out a few things we hadn’t noticed ourselves. I felt very comfortable throughout the process. Would absolutely recommend them to anyone dealing with moisture or mold issues."

FAQs for mold & toxic material test projects in Grayslake, 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.
