"Though the gutters were cleaned in December after the leaves had fallen, this spring of 2024 the gutters were over flowing!! I texted David regarding this issue he said they check the downspouts using a leaf blower. This spring I noticed no apparent debris from the downspouts being blown out. David said that my house is surrounded by trees and the downspouts are probably blocked again. This is 4 months later!! What would be blocking the gutters from draining. He said he'd come out but would have to charge me again, again for a service I paid for that wasn't completed properly in December. Would not recommend or use again."

FAQs for mold & toxic material test projects in Harrison, MI

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.
