"Max just left my home and I already know he is the person to make our home safe! He will pack out our basement, remove mold, and remediate asbestos. I couldn’t be more happier! We are also looking for him to epoxy the floors. "

"This company is amazing. I’ve used them twice – once to remove mold in our attic and 10+ years later to remove mold in our basement (both due to separate leaks in each location.) I would highly recommend them. Bob (the owner) and Felix are personable, knowledgeable, reliable, honest, professional and experienced. Their assessment of the problem has always been spot-on and their work is incredibly thorough. They’re the best!"

"We rented one of Brigitte's air purification units, and within days, the house was smelling fresh and clean. <br /> We decided to purchase the unit, and she now supplies us with filters and service when necessary."

"This is the second job Preferred has done for us. Last year we needed mold remediation done to our roof and attic. It was a huge job. All the workers were pleasant and tried to be as unintrusive as possible. Each evening they left my house spotless only leaving what was absolutely necessary. When the job was done, my house was impeccable. The owner told me that he does other types of work on homes, so when we decided to put in new windows we called Preferred to assist with the general contracting work. They made suggestions of window distributors for us to call and brought out the distributor they usually work with. We were also getting the house painted inside and out. Preferred is managing that project for us, as well. Their pricing was a bit higher, but not enough to give up the security of knowing we were in the best hands possible. They started work this week, and again, the house is immaculate and the workers and project manager wonderful. We do have the same project manager as last year. The reason for the B rating on promptness is that on both projects we got a bit of a later start than anticipated. However, once the projects were underway, they were at my house promptly at 8 and worked through the day sometimes until dark. When there was an issue (generally weather related), I always had a call giving me a heads up with numerous apologies. We aren't quite finished yet with this project, but I can honestly say that not another piece of work will be done on my house without consulting Preferred first. They give me honest answers regarding where to put the dollars. <br />"

"The body was found during a police wellness check. CSI was called by the local police department to transport the body. Once that was done, the floorboards of the room where the deceased was located needed to be removed and a bio-hazard barrier applied to the room. All of the clothing, bedding, towels, mattresses, cloth-covered furniture, window treatments, etc. had to be removed from the entire house. Walls and remaining furniture had to be sanitized. Floorboards were replaced and new carpeting installed. The only reason I didn't give them an A on Punctuality is because the work took longer than I expected. Warning to make sure everything you want to keep is on their written list. I "lost" things I thought were on the list, but with the chaos of the death, etc. they never got onto the list."

"PuroClean showed up and began immediately to dry the damage floors. They also worked with our insurance company helping them understand the damage caused by the leak in a very short time, like less than a week. They were professional and provided Value for the their work including drying the damp areas from below the floor and above removing the possibility of a mold issue."

"Sal was recommended to us by a friend that found him here on Angie's List. We had him completely gut our bathroom to the studs. Overall he did a great job. Everything was undated that needed to be including plumbing, exhaust fan, mold resistant wet area dry wall etc. The shower he built turned out perfect and we get compliments from everyone thats sees it. At first we thought his price was a little high, but we are so glad we went with him. You actually do get what you pay for. I gave him a "B" under responsiveness only because we had to wait approx 6 weeks for him to schedule the work. With that said it is a good comfortable feeling to know that he is that busy and in such a high demand. I would recommend Scott to anybody that wants a honest quality job done at an affordable price point. <br />"

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