-Residential home mold assessments and testing which include air, swab, and tape lift testing for mold. All samples are sent to a certified laboratory for testing. There are over 125,000 known species of mold. Don't assume! Get it tested! After the initial testing you will receive the results and a mold clean up plan on how to clean the mold if tests are positive. After the clean up I will come back for post testing to make sure the problem is solved. I also do asbestos and or mold testing after a fire or flood for the remediation experts.

"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!"

Molds and other allergens are especially troublesome to persons with prior sensitivities or immune compromised. In addition, these allergens can create in ones formerly unaffected new and onset intolerances. When this occurs health is put at serious risk. We do not take any health complaint related to indoor air quality lightly. We understand from our experience in this field that no two people are affected the same way when it comes to mold and other allergens.

"Robert from Oasis was incredibly thoughtful and provided great insight into our situation, patiently explaining his thinking. I would use them again and highly recommend."

FAQs for mold & toxic material test projects in Hartsdale, 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.
