"Greg the inspector came out, nice guy very knowledgeable, I spent 14800 in waterproofing and mold removal, new sump pump and a air purifier. Greg and I went over everything the crew was going to do. Well where the water issue I was most concerned about , they side step and only put the drain tile down the middle and not at both sides. Stay Dry ended up sending 1 person to put tile in on both sides and fixed that issue, now I am having water issue where I was not having issues before and come to find out where my water line comes in they just put gravel under and did not put the concrete back in that area. So now I have a new leak and I can't seem to get this company to come back out for a 3rd time to fix this issue. Also I have water coming up from the newly concrete floor, I was told that the concrete has to cure for awhile which I understand that, but I don't think it should be seeping up along the cracks where the new and old concrete meets. Waiting on this company to correct."

"He did a great job on replacing the walls, painting and installing the bathroom fan. Where I find fault is he also installed a brand new floor and the grout is chipping, cracking and coming up all over. We contacted him several times to get this repaired and he never came over to fix it. Now we can't afford to have the grout repaired and we are stuck with the floor like this."

Mold & toxic material tests FAQs

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.
