Get matched with top indoor air quality testers in Chalfont, PA

"Tim was fast and professional. His work is much appreciated. We would highly recommend this service."

"Good pricing and estimate over the phone. Great communication and prompt and clean service. Radon went from 9.5 to 0.5 in the basement."

"The mold testing is fine. The mold remediation company is very sketchy. Just buy some air purifiers."

"Sebastian came to my house to provide an estimate for an air quality test. I described the odor I was concerned about. He immediately spent some time determining the source of the odor (most likely a dead rodent in the wall of a storage closet) in my house. He recommended a good exterminator to open walls and remove the offending rodent but also advised how I could do it myself easily (and much cheaper). I always appreciate a contractor interested in solving my problem, especially when he doesn't get any business out of it. Sebastian was extremely knowledgeable and obviously very helpful. Anyone in need of air quality testing could not go wrong contacting SS John & Marin Restoration LLC"

"Outstanding radon mitigation company. Strongly recommend!"

"They were great to work with! They arrived promptly and were very professional and courteous from the start to finish. Great experience, and a pleasure to work with. They referred some professionals for the remediation and to fix the home from the flood damage. They walked me through the whole process and made sure I was happy the whole way through."

"Wow. What a great experience with this company. My wife and I bought a circa-1888 Victorian in Chestnut Hill five years ago and did an extensive renovation. Little did we know that, for decades probably, water had been leaking behind a section of wall in our third floor master bedroom and dripping down to our second floor office. We started noticing subtle signs of damage, opened the wall, felt moisture, and smelled mold. We first had the source of the roof leak fixed. Then, per the good reviews on Angie's List, we called Mastertech. Mr. Leonard Wendowski came out, used a moisture meter to determine the extent of the damage and did a pre-service mold test, the results of which showed high levels of mold. Leonard carefully explained what his company would do to remediate the issue. Although my wife and I were horrified about having to take off two walls in our fully-decorated house, Leonard's obvious technical knowledge and his professional manner put us at ease. On the day of the work, the team arrived on time, covered the wood floor, carefully erected an excellent plastic barrier sealing off the affected sections of the rooms, and as neatly-as-humanly-possible performed the removal of the walls, carefully avoiding damage to our trim and electrical. Leonard's team were the nicest guys around, and I felt completely comfortable having them in my house. Jarrod was the certified mold remediation specialist and Tony is the certified technician who set up the powerful dehumidification and negative air machines. Although all the accessible mold-covered sections were remediated directly, they explained to me that as mold dries it goes in search of moisture by shooting out spores. So while the dehumidification was going on, the powerful pull of the negative air system effectively pulled all the mold spores through a filter and out the window. They kept these big machines going for 24-48 hours per protocol and then came out again to test the moisture. After the areas were sufficiently dry, they carefully removed all the machines without a bit of damage to our stairway walls or handrails. Post-service testing showed only normal, natural, minimal amounts of mold remaining. My wife and I could not have asked for a better experience, and we therefore highly, highly recommend this excellent company.

"Jason was excellent. He was out to the house the same morning we called. He was very professional and knowledgeable. He eased our concerns and followed up later in the day when out test results were recieved. I couldn't have asked for more."
