"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."

Dark mold growth, while common, can cause allergic reactions and various symptoms even when in the attic.
Great project which ultimately lowered the indoor humidity by 20% making it more livable for the family, storage where there was none previously, and much more healthy from and indoor air quality perspective (no stinky bacteria).

"We had some water in our basement over the last year.  We were concerned that we might have some mold that needed to be cleaned up.  Jim gave us a mold inspection which was free.  Turns out we had a tiny bit of mold no larger than the palm of your hand. He told us how to clean it up ourselves and recommended great products from the store.  Really nice professional gentleman.  He certainly could have charged us for this advice!    We did not know if we had a large or small problem.

"Ryan's work effort exceeded my expectations. Seeing him apply the tools of his trade had me briefly wishing for a bigger mold problem. However, the cost of resolving such problem quickly brought me back to earth. I am thankful that scope of work to remove the problem is small and doable by a DIYer."

"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.
