"Scott from Landmark Inspections performed a home inspection of the home my husband and I are purchasing. We are first time home buyers and this is our first home inspection. We were very impressed with Scott from beginning to end. Before the inspection, he was responsive and communcative, answering every one of our phone calls and emails. The inspection was thorough and Scott and his trainee inspector (also Scott) took the time to answer our questions and explain everything they were doing/finding. The inspection did not feel rushed or like Scott was trying to get through it to move on to the next. The report he sent us (48 hours after the inspection, great turn around time) was very throrough, contained useful information about our future home, and clearly laid out a heirarchy for recommended repairs. We also got a termite inspection, sewer scope inspection (which was also performed incredibly professionally by Melvin from Knox & Knox Solutions), and raydon test. In total, we paid a lot of money for these services, but it was money very well spent. We would not hesitate to recommend Scott, Landmark, and the other service professionals with whom he contracts."

"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."

"Our inspector, Joe Donnelly, was recommended by our realtor. He was very nice and did catch a lot of smaller things on our home inspection. However, he majorly screwed up on the electrical part of the inspection: he noted that there were a few double tapped breakers that we should get fixed, but somehow did not notice that none of the breakers were GFCI or arc-fault protected. He also missed the lack of sticker on the box, which meant the electrical work in the house had never been inspected (or at least never passed). When we called an electrician in to fix the double tapped breaker issue, he immediately pointed out the non- arc fault, non-GFCI, no inspection situation and was shocked the home inspector didn't notice either issue. We now have gotten estimates of several thousand dollars to fix the electrical issues, expenses we were not planning on. If Joe had found these issues, we likely would not have gone through with buying this house."

FAQs for radon gas testing projects in Fort Washington, 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.
