"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. "

"We recently inherited a home in the suburbs that we had no intention of moving into. We knew there was some mold in the basement, but decided to sell it “as is” and see what happened. After putting it on the market and receiving numerous comments from buyers about the basement, we decided to get it remediated. I have a busy work schedule and couldn’t meet them at the property for an estimate, so instead they let me email photos, measurements and a drawing of where I thought all the mold was. HUGE timesaver. We asked for a quote to remove the mold and to waterproof the whole basement to make it more attractive to buyers. The quote seemed reasonable so we scheduled work to start within a couple days, when we were planning to already be there to clean out the garage, which was SUPER convenient. The morning the work was scheduled, we realized that the house didn’t have power. I called Indoor Air Repair panicking thinking we’d have to reschedule and they said it actually wasn’t a problem because they could just bring a generator. What a relief! Their guys were really professional and stayed late to get the entire job done including waterproofing in a single day (we were convinced it would take at least two). They found way more mold than we knew was there so they took out more drywall than we expected, but they kept us in the loop the entire time so there were no surprises. They also kept air scrubbers in the basement for an extra couple days to make sure all the mold spores were gone. The basement looks and feels so much better now with all the mold gone. There’s been heavy rain out by the house several times since the work was done and the basement has stayed dry as a bone. These guys were so easy to deal with and they did a great job. If I ever have mold again, I know who to call."

"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."

"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."

"I recently had Bernhardt Restoration handle mold remediation in my home, and I couldn’t be more impressed. From start to finish, the experience was outstanding. The remediation specialists who came out were true professionals—they arrived on time, worked efficiently, and demonstrated a level of craftsmanship that is rare to find these days. Their workmanship was meticulous, and it gave me complete peace of mind knowing the job was done right. Beyond just solving the problem, they showed respect for my home and my time, which made the entire process seamless. I will absolutely use Bernhardt Restoration again in the future and have no hesitation recommending them to anyone in need of mold remediation or bathroom restoration work. They are reliable, professional, and deliver results of the highest quality."

"All the Way Home Inspections found dark staining in the attic of a home I was considering purchasing. They tested the area, confirmed it was mold, and provided clear information that helped me make an informed decision. While I ultimately chose to walk away from that property, I truly appreciated their thoroughness and professionalism. I’ll definitely use them again when I find my next potential home!"

"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 Northbrook, 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.
