Get matched with top mold & toxic material testers in Newtown Square, PA

"I had a bad experience with a different company, and so, I was a little skeptical and wary when I started working with Jason. He was very patient with me, showed me all his credentials, took the time to explain what he would be doing and why, and otherwise showed me that he runs a competent and professional outfit. The type of test they took satisfied my insurance company and they even offered to let me pay after the test was done. In short, I am 100% satisfied with Jason and Atlas Environmental Inspections. It was great being able to work with such a great company after having had that previous bad experience."

"Straight forward and efficient, great communication, costs transparent. When presented with challenges of temporary electricity outage was resourceful and creative to get the job done even more than predicted. Cleaned up after work done. Respectful and honest. Would highly recommend! I should have had them do this work years ago, glad I worked with Luis & Steve!"

"I saw NAL East Environmental, read their Profile & was extremely impressed. Their Inspectors’ are Highly Educated Professionals. Words can’t describe how Grateful I am for Mark Stern & Joe Chairmonte. Testing was explained with Professionalism, Knowledge & Compassion. Mark is a Genuine Professional. He was Respectful & Kind as he explained and knew what should be tested. Joe was already set up. They were extremely thorough. After testing, Mark said, “Please call with any questions,” He was true to his word. After finding Acute Mold issues in Our Rental Home of 17+!years. Mark showed much care for Our well-being. It’s RARE to find a Co. with such Caring Inspectors w/High Moral Values, Yet, here they are!! I hired Mark & Joe again for Surface Testing. I’ve since referred Mark & Joe to Family. NAL East is The BEST! Thank you & Many Blessings to Mark & Joe. You are Amazing Assets to NAL Eastern & Our Community!! Jacqueline W., Yardley, PA"

"We had our radon fan replaced by Radon Bros in January 2025. From the beginning, the new fan was noticeably louder than the previous one. At that time, the technician advised us that the increased noise was due to the fan being stronger than our prior unit. Over time, the fan became increasingly louder and ultimately stopped working in early December 2025. When a technician returned to replace the fan, we were informed that the fan originally installed was defective and that Radon Bros had stopped using that manufacturer due to known issues. Despite this, we were charged a $99 labor fee for the replacement. We do not understand why we were responsible for this charge when the failure was due to a defective fan that your company was already aware of and no longer installs. We felt we had no choice but to pay the $99 in order to have our radon mitigation system restored and functioning properly. "

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

"Tyler came over to assess basement moisture and he thoroughly inspected the area and shared his professional opinion. It didn't involve him doing anything at first--the step is to call a plumber. He didn't charge for his time and insight, and I was really impressed by that."

"They were really helpful and polite they explained the job from start to finish and they explian how radon is harmful."

"Honest, trustworthy, professional"
