"After Ida ripped through our area, we had water in our partially finished basement, just like everyone else in our area. As we removed the wet materials, we discovered a ton of mold. Dillon, Ray and his team were quick to respond, professional and we are thrilled with the quality of work. Within a week of contacting Aerotek, our mold situation was resolved. We couldn't be happier with their work and all of our interactions."

"I received my call earlier today, and discussed my concerns. I wanted to start the process toward remediation asap! Mr. Griffin was at my house 4 hrs later. He was professional, compassionate, and answered all my questions, since this was a new experience for me and of concern. By 3pm, my home was totally inspected and my airborne samples were collected and headed to the GA lab for testing and results. Within minutes, a email to track my lab results status was sent to my phone! I can't do anything until the results are determined,and Mr. Turner, Senior Mold Analyst gets the report! The ball is rolling! MsV"

"Steve was professional and easily accessible throughout the project. I felt he provided a fair price for the scope of work. His team was able to effectively remediate the asbestos issue which was confirmed by a third party air testing company. Would definitely recommend Steve and his team for future hazardous waste removal services."

FAQs for mold & toxic material test projects in Philadelphia, PA

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.
