"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."

"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 would be remiss if I didn't take the time to write a review for Green Home Solutions. I was in a total quandary when I spotted black mold on a baseboard in one of our bedrooms. I knew immediately that we had to have this checked out since my wife uses that room a lot when I snore. Not knowing who to call, I went on a neighborhood website and found the info for Green Home. I immediately called and was in touch with Autumn and then Jim within one hour. We set up a testing meeting and Jim was there at the exact time and was ready to go. After some pleasantries (and he is a friendly guy) he got to work checking out our entire home and that bedroom in particular. He used very high-tech equipment and pinpointed the spot with the mold. We determined that the window on that wall had rotted seals and was surely the source of water getting in. Jim left and within 2 days I had the complete report of what he found and a detailed report on the remediation. I quickly okayed the project and we had a date the next week for work to begin. Again, Jim and his assistant were right on time and set everything up to begin the remediation process. Let me add, at this point, that they set everything up to cause the least amount of mess and dust to any other part of the house. They got to work and within that day had the wall out and identified the mold and its source. They also found some mold in the attic and identified those sources as defective vents from bathrooms. Jimâ s friend Dean, a roofer, identified those problems and will be remediating those issues. After the entire process of removal was over I still had some questions and Jim came out again the next day with a new HEPA unit and helped me clean dust from the room. A week later his wife, Autumn, was out to do a final check of mold levels in the bedroom and attic. We are now in the clear (no pun intended). Being a senior citizen I deal with a lot of home repair people and Jim Blandi is one of the best, nicest and most professional company owners you will deal with. GHS gets my 100% endorsement.

"We had water seepage/damage in our basement and had to pull up all of our floor tiles in 2 rooms in the basement before we could install a new sump pump/drainage tile system. The floor tiles looked suspicious for asbestos containing materials (ACM). We took a sample of the floor tile to Bussey Environmental to be tested. Bussey confirmed that the tile (but not the mastic underneath) contained ACM. Bussey recommended Bluestone to remove and abate the floor tiles and mold. We hired Bluestone and they gave us a very detailed proposal (much more detailed than other proposals we received) and a reasonable price. Bluestone arrived on the appointed time and day (even came a little earlier). The crew chief was James (Jimmy) Santellano. Jimmy was very professional and friendly and could not have been more accommodating. Bluestone removed all of the floor tiles and abated the mold in the basement rooms. They performed the work in accordance with strick industry standards for removal of hazardous materials. They finished the job in about 6-7 hours and after they finished we had the air tested for both asbestos and mold. We passed all of the tests. Bluestone left the job both clean and neat and ready for the next phase of our basement work. We would recommend Bluestone very highly."

"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."

" We were concerned that our home had mold after we had a leak from the bathroom. I hired All the Way Home Inspections for mold testing and was relieved to know that no abnormal mold growth was detected. The service was fast, professional, and reasonably priced compared to other quotes we received. I would definitely hire them 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.
