"Very well. I couldn't find the recommended product at two local stores, but I was able to order it online for a reasonable price. The process for using the product was just as described and didn't take very long. I'm pleased with the results. I really appreciate getting good advice for free, and if I ever have a larger problem, I'd contact Dutch's Mold Inspection again. I will also keep the contact to refer to others."

"Gil was very professional, on time, and very kind. He went over and beyond in helping us get the mold in the basement of where we were renting tested because our landlord would not take it seriously. Having our own testing done and a lab report of the findings mad it possible for us to get out of the lease and get our security deposit and rent returned to us so we could move out of a toxic home."

"ClearFocus Home Inspection was very professional and thorough. I greatly appreciated the punctuality and attention to detail for a comprehensive evaluation of my house. They were called for a preliminary evaluation of my home before listing for sale. It was a lucky thing that I did as there were many things unnoticed by myself that made a big impact. The report was authored and promptly e-mailed to me within 24 hours. I will recommend ClearFocus to anyone needing this type of service. Paul Pope was the inspector that day and I would recommend asking for him."

"Mr. Frank Trust and his employee, Toby, were prompt, extremely thorough, polite, professional and so considerate. Due to a leaking garage roof, mold and mildew developed and much of the stored items were destroyed. Mr. Trust and Toby spent about 7 hours cleaning, decontaminating and power washing the structure. They even cleaned, sanitized, wrapped and packed the personal items that could be saved. They did a fantastic job. Mr. Trust is a genuinely kind man. I’ve already recommended him to a friend. Thank you so very much for the service."

"This company is very professional and responsive to your needs. I feel such a great relief to have Safehouse Solutions take care of my bathroom. This company stepped in and fixed problems that the previous company did incorrectly. Mike Daddario safely and correctly removed the mold caused by a leak in my bathroom. Nancy Sharber not only coordinated the project , she kept me informed at all times and she handled the paperwork for my insurance company to release payment. I highly recommend this company."

FAQs for mold & toxic material test projects in Northfield, OH

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.
