"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."

"Mack’s Mold Removal really knows their stuff. Great prices, professional service, and great people to work with. I recommend them to all of my clients for both investment and personal properties. Mold can cause serious problems, from affecting the health of the people who live or work in buildings with mold, to affecting the price of a property that’s on the market. I know that once Mack’s Mold Removal gets the call, they work quickly and professionally to get the problem solved. I’ve talked to Jeff a number of times and it’s obvious that he is passionate about the business and committed to solving all of the customer needs."

"The price was more then fair. Dave who came out to look and then give estimate very nice and professional Answered all my questions.They were able to come out aonly a few days later. Dave came with 4 workers who did the actual work. They were very nice, professional respectful and not only did a nice job with taking down the walls and ceiling area needed but left them in good shape only taking down what they needed to do the job while keeping tthe remiander of the wall and ceiling area looking neat and sharp. They also did a great job of cleaning up I would hire them again but sure hope that is it for the mold in my house and I wont need their services again but I hu=igjly recommend them for anyone else looking for mold specialists"

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.
