"Radon level was 11.5 before remediation and .24 after, so the result could not have been better. The installer, Dave, was first class from start to finish and owner Marc graciously adjusted his schedule to fit me in sooner as I requested. My only complaint was the price, and only because the home inspector who tested the radon levels told me the cost would be $800 to $1,500. My realtor said about $1,000."

"Contacting and scheduling an appointment with Larry & BPG was a breeze. They were able to set up an appointment and tell us what we might be able to expect in terms of associated costs & payment options and timing for the inspections over the phone when we called. Larry's partner set up the radon test a few days in advance of the inspection so that it would be ready to collect when we did the inspections. On the day of the inspections Larry was right on time. He started his inspections outside and worked his way inside the house. He allowed us to tag along while he conducted his inspections and we learned a few things in the process, which was great! He took many photos throughout the inspections that he utilized in his very well organized and detailed reports (even our real estate lawyer was impressed with his reports!). We received our reports less than 24 hours after the inspections were complete. Overall, it was great experience, and we would recommend Larry and BPG to anyone looking for various home inspections. Larry & BPG are almost a one stop shop providing numerous types of tests and inspections, which is a great time saver for all involved. <br />"

"This is the second time I have used Scott and once again he was very professional, personable and informative. Scott looked at entire home inside and out. He was very thorough. Information that needed to be imparted regarding home defects was done succinctly and in a manner that was easy for me to understand. Scott advised me that everything we spoke about would be in his Home Inspection Report. I checked my hand written notes against the Home Inspection Report and not only did it have all the information given to me the day of inspection but much more information was included and appreciated. Scott explained the radon remediation system in the home. I will use the home inspection report to fix repairs not done by sellers. I have recommended Landmark Inspections to a friend and they were very satisfied with the service provided to them. When I called Scott to set up an appointment, he advised me he had some other appointments scheduled, however, because my time was limited to get the service done, Scott made an appointment for my convenience. I appreciate Scott fitting into my time limits and doing a thorough job when he arrived. Scott was early for the appointment, he was at the location prior to my arriving and I was early for scheduled appointment. I would definitely use Scott again."

"John was great. He was thorough and took a lot of time walking us through the home and explaining everything that was a concern and strength. He was personal and professional at the same time. We had him test for mold and radon as well as the home was older and he also inspected a detached garage. The inspection reports and invoices were all available online on a secure site for download, which is very convenient."

"Nick was extremely thorough and knowledgeable. He went well above and beyond my expectations for a home inspection. Described in detail every potential issue from the absolute minor to the major. Nick's attention to detail was so good that he even pointed out how the HVAC contractor used the wrong kind of tape to affix the ducts to each other. He also has a lot of knowledge about the area, its history and how that affects the construction of the old homes that are so common here. I was absolutely blown away by Nick's work and strongly believe that no one should ever buy a house without having Nick and Strong Foundations inspect it."

"I contacted three different companies to obtain estimates. Only one, RTE, offered to come out and inspect the property and thoroughly explain what would be needed. There was no pressure to sign a contract. The other two companies had me answer questions about the house and then sent their estimates. I was impressed that the owner of the company himself came out to provide the estimate. Their expertise, customer service, and quality of work far exceeded my expectations. I just got back the results of the post-remediation testing and level was reduced to 1.2, I highly recommend this company. They serve a wide area of the Delaware Valley."

FAQs for radon gas testing projects in Sellersville, PA

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
