"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."

"I had a great experience working with Al. From the get go they were very responsive to the request and promptly scheduled an in home consultation. Al is certified in mold remediation and walked me through the steps in detail. Working with them through the remediation process was a breeze and I was given quick updates on the progress and the outcomes. They also accommodated an adhoc request to remediate an area not in the scope of work at no extra fee. They are thorough and meticulous in the process and attention to details is excellent. I had a truly great experience working with Al and also Sebastian and will definitely recommend them for any mold remediation work. Thanks, Rohit"

"I didn't know what I was in for when I needed a radon mitigation expert. I figured it would be expensive and take forever. The Radon Bros were the best thing that could have happened! Extremely professional, knowledgeable, very affordable, and quick to respond! A great experience, start to finish!!"

FAQs for mold & toxic material test projects in Garnet Valley, 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.
