"John came out to inspect our old house for asbestos. We thought there might be something there and indeed John found it. He offered a number of solutions, and rather than selling a service just to sell, he spent time to educate and strategics about the best treatment option. We haven't committed to full removal but are grateful for John's expertise and patient outline of options."

"Working with Advantaclean on mold remediation project was a nice experience. We noticed mold in patches in our bathroom, Advantaclean they worked on this mold remediation project and the end result, mold free bathroom. After they completed their work also did post test and result came negative. The crew worked on this project are very professional and they did the job nicely. I would highly recommend using them for any mold remediation needs. Thanks to JT, Kaitlyn, Ian and the crew who worked on this project."

"Aaron and Mike were very good at explaining the entire process of checking our home for mold and air quality. We did have them clean our air ducts and treat them as well. All clean up after the project was perfect and no mess was left behind. Prices are great. Will use them again if needed!"

"Overall was good for what the service is. The technician was a postal worker and home inspector. So mold test company appears to be brokers. Their pricing was competitive from other quotes I received but I honestly think it was pricey for time spent and what they do. But like I said the price was pretty standard from the companies I called, in my opinion. But the technician was attentive and knowledgeable, and friendly."

"I had a water heater leak that contaminated a 4x5 room with mold. RMS came over and thoroughly explained what they can do to fix it. They were punctual and also informative while they worked which made my wife comfortable with their work. The mold is gone and my family is safe. I would hire them again if ever needed."

"I hired them to take care of a really bad mold problem in my basement. With me having a mold allergy, I needed someone that could be very thorough. Let me just say that they did not disappoint one bit! They were incredibly detailed and truly did amazing work. I seriously couldnâ t thank them enough. If I ever have another mold problem in the future, I know without a doubt Iâ ll be hiring Mastercat again."

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