"I love working with a home inspector who is thorough. Joe was fabulous, explaining all details about appliances, furnace, mini splits, and other features of the home to my buyer. He performed a home and pest inspection. She feels comfortable to take on living in a 1910 home, the home that will be hers!"

"????? Highly Recommended Review: Funari Public Adjusters I am writing to share my experience with Funari Public Adjusters, and I cannot say enough about the exceptional service provided by the owners, Chris and Vito, and their entire team of experts. From the very first call, they were immediately available and responsive, helping me during my critical time of need. The team went above and beyond in every aspect?from assigning a dedicated representative to handle my claim, to guiding me through the entire process from start to finish. Every staff member I interacted with was friendly, professional, and extremely helpful whenever I had questions. I have used this company on three separate occasions, and each time they exceeded my expectations: When a neighbor?s tree fell on the back portion of my home. When I experienced a theft at my rental property, resulting in damages and losses. Most recently, after heavy rains caused significant roof damage to my home, including my top-floor"

"I am a construction attorney who worked for the U.S. Army Corps of Engineers for 32 years before I retired. I also maintained a par-time practice throughout that time. and represented many home buyers. I found Mr. Muehlbronner from AHI, Inc., to be by far one of the most, if not the most competent and rigorous inspectors that I have had the pleasure of working with in my career. He uncovered numerous problems in the 1st house that was under contract . We had to walk away from the first house. This was the second house that he inspected for us within a month. Mr, Muehlbronner was well worth every penny spent on his consultation and inspection services. I would wholeheartedly recommend him without reservation."

FAQs for radon gas testing projects in Lansdale, 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.
