"I could not recommend Clawback more! Gary was extremely helpful and transparent about the process for testing our air for mold. Our tech Robert was able to come out the next day, he was so knowledgable, friendly, and thorough. We had mold remediated about a month ago and wanted to get our air tested for peace of mind and they couldn’t have made it an easier process! 10/10 would recommend ☺️"

"I called Adam’s Asbestos and Mold testing after we had a small fire and our contractor told us there may be an asbestos issue. Adam himself called me back within minutes, and he was at the house right away! He was professional and very detailed in his work. Best part was, that due to Adam’s report, our renovation was covered by insurance!!! Huge thank you to Adam’s Asbestos & Mold testing!"

"I had a poor experience. I hired this company to do a mold assessment in my apartment. I dealt with the owner. First, he requested cash or check payment only. He made an appointment and did not show up or contact me. I had to call him. In one of the rooms, the pipes above and whatever else the cause of the leak was, had been leaking repeatedly for 40 years, and the plaster constantly replaced. I was worried about mold ABOVE the ceiling on the beams and studs and not just the visible mold on the ceiling plaster and I worried it could be black mold. He did not seem to listen to what I told him and he did not use a water meter to check for saturation or a borescope or any other tools except taking a surface sample and air sample (the borescope and water meter I did not know about until after I had paid him for this inadequate job). He did not mention anything I said in the report. He was also rude and unkind and never provided me with a receipt."

FAQs for mold & toxic material test projects in Valhalla, NY

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.
