"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."

"Mold test took air samples inside and out after we discovered some questionable spots that worried us. Samples are sent to a lab for analysis. We subsequently purchased a mold remediation kit from another firm and treated the house. We are breathing easier now. Thanks!"

"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."

"The team was very knowledgeable and extremely professional in their cleanup efforts and rectified all problems associated with our water damage due to a recent leak in our basement Tim was fantastic in organizing and completing the project. He also served as a wonderful resource person in recommending a wonderful and honest roofer. Tim's team was courteous, and highly dependable. They removed the mold and repaired the water damage in an expedient manner. Tim's coordination of the cleanup was outstanding. I highly recommend Bioclean for their fast and superb service."

"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 called several vendors to come out and quote remediating my basement after a nor'easter knocked power out and resulted in a flooded basement due to primary and secondary sump failure. This was my first time ever contacting Bio-clean. Tim was great. He responded immediately, came out to review the job, outlined a plan of action, clearly explained the scope of work to me, and submitted pricing. His pricing was competitive. Some of the competitors did not even call me back. This job was NOT covered by insurance and Tim worked with me on the cost of the job. We awarded the job to Bio-clean that same day and Tim and his team were back out to my house within a couple hours. They worked until 10 PM the first night in an effort to get the wet carpet, carpet pad, and other wet material out of the basement and to start the remediation process. They set up fans and dehumidifiers and quickly worked to get the basement drying while spraying anti microbial to prevent mold growth. They returned again over the next few days to supervise the remediation and to make minor modifications to the equipment to optimize the drying process. The whole process took several days. They left my basement dry, clean, and completely swept up. A job well done. I would definitely use them again although I hope I never will have a flooded basement again in the future."

"Stephen and his team are professional and extraordinarily thorough. I moved into an apartment that had mold. Landlord knew. I found out after move-in. Testing came back showing the predominating species and spore counts. Landlord still would not take care of it, so I had to move out. Stephen went out of his way to answer all of my questions and set up both mold remediation and content cleanup for me in the new apartment to ensure nothing was transferred from the old one. I moved into a smaller space, so this reduced the cost as well. I now have peace of mind knowing that I am again living in a healthy, clean space. Thank you so much!"

"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 Harleysville, 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.
