"Is this business even open any more? I've tried calling several times and the phone rings twice and then there is silence. There is an option to contact them on their website, but when I leave my info and click submit, nothing happens. Can anyone recommend another service similar to this one? The mold smell is coming out of my hvac ducts again. I'm in the Joliet area ."

"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."

"Great experience with Jim, he seemed knowledgeable and assured me that I didn't have a mold problem. He also saved me money by not doing test he felt were unnecessary. My only concern was for 300 bucks if he should of tried to do a few test to check the pm levels or voc levels but he said he has a good nose for such things. He gave me good tips to help with my humidity which he stayed was the main issue in my home. Overall good experience"

"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."

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.
