"After having medical issues and testing positive for mold exposure, I contacted Aerotek to inspect my rental condo for mold. Luis did an inspection and found toxic mold spores in my bedroom that were coming from the furnace closet area next to the bedroom. My landlord would not remediate the problem so Luis came on my moving day and disinfected all my clothing and furniture located in the bedroom. Luis was always available to answer my many questions in this stressful situation. II felt confident mold spores would not be moving with me! Brandon was also very helpful in this whole process. I would highly recommend using their services should the need arrive."

"We can’t begin to say enough about Ray and Aerotek. They literally saved my son and daughter-in-law from a house they bought that was filled with mold, toxic mold. Aerotek was so professional, and so empathetic throughout the entire process. They were constantly updating us on the job, sending photos and videos, and getting the home back to a top level of cleanliness so that they could finally start to move forward. The Crew was careful, respectful, and diligent in getting this house, cleaned and rid of mold. There aren’t enough words to say how grateful we are to Ray, and what a kind man, and honest contractor he is. If you need mold remediation, you should look no further than Aerotek and Ray. You also won’t beat his prices anywhere, which is only a bonus next to all of his other attributes."

"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.
