"DO NOT PAY CASH. I want to do a chargeback with my bank but I can't because I paid for their services in cash.. I was having multiple health symptoms consistent with mold exposure so I hired alameda mold guys to come and assess my place for mold in Aug 2024. Lab report showed no mold spores. About 4 weeks later I hired *another* company called certified environmental or something who emailed me their lab findings which showed an extensive amount of mold. I emailed the lab findings to the inspector from Alameda Mold Guys. I then called, texted, and multiple times emailed the guy from Alameda mold guys about a partial refund.. who kept telling me he would "get back to me" about the extreme difference in mold findings,but he never did get back to me. So it cost me double the price it should have cost to verify that there was mold in my place.."

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.
