"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."

"A couple months late with this review but JT was great and he’ll be my first call if I ever have any mold issues again. I had a bunch of vintage items that I didn’t realize had mold and when I tried to clean them, I made it worse. I got rid of them but was worried mold had spread in the air. JT did a walk through & recommended air testing. He gave lots of explanation about mold, treatments, etc so I thoroughly understood my situation and air test results in context. No sales pressure, just a straightforward, knowledgeable guy. Collected the outside air sample (the baseline for comparison) during a polar vortex and hustled to make the last Fedex pickup on Friday night so test results would come back ASAP. Has an independent lab do the analysis of air samples and report, which is good practice. Plus, we are getting bonus mileage out of the air purifiers we got now that it’s allergy season. Good guy, good communication, good job!"
Large attic before remediation. This attic was covered very heavily in mold.

"This company is great to work with. They did some mold testing on parents’ home and did excellent work. They also did some work on my home. They replaced a water heater and bathroom fans. He was easy to get a hold of, personable and come over right away."

"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."

"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!"

"David called me shortly after I posted my service request with Angi and he made an appointment for the same day. He quickly understood my possible mold problem and conducted a thorough test. Meanwhile he told me what equipment to purchase in order monitor the moisture on the wood floor following the repair of the water leak. He send me the test results in 2 business days. Besides all that David is very personable and is available for follow-up questions."

FAQs for mold & toxic material test projects in Hoffman Estates, 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.
