"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."

"Jim was professional and punctual and gave us an honest and detailed assessment of the attic mold problem.  Mold was found by our home inspector prior to listing the house for sale.  The problem was small and well contained but required cleaning and encapsulation.  Structure Dry did the work for a very reasonable cost, they used top-quality products, they were very clean in our house's living areas, and they provided a full transferable warranty, which was very important for our sale transaction.  Later, when questions arose, Jim came back for another visual inspection of an additional area of concern, documented his opinions for us, provided suggestions for cleaning products, then even provided a small free supply of the expensive mold encapsulant to be used in case the new owners required!  We had a very positive experience and we would recommend highly!

"They were very professional honest and showed up on time. Another company to come out and they were trying to pitch me and the idea of me destroy my entire basement to get rid of some mold. The guys at Black rock environmental did not! They even took an air test afterwards confirming everything they said they would do. I strongly recommend them. Two thumbs up!"

"Because of the extent of the staining in the attic he was concerned the mold may have gone airborne and contaminated other areas
Of our house. He suggested taking an air test on the ground floor to rule out this possibility.
He also did a complete inspection of the entire house.
As it turned out it was mold in the attic and needs to be removed.
Bob is providing us with certified companies to bid on the job.
Fortunately the mold had not gone airborne throughout the rest of the house.
Bob is extremely knowledgeable and I highly recommend All Suburban Services to anyone
Concerned about the presence mold in there home.

"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 Oak Park, 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.
