"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!"

"Jonathan was professional and incredibly helpful. He was able to explain what he was looking at, answered all of our questions, and was more than happy to show us how things worked and what to look out for. The report was thorough and left us with a solid understanding of the home. Thank you!"

"If you’re considering 58 Foundations, do yourself a favor and stop right now. I cannot, in good conscience, recommend this company to anyone—let alone friends or family. Their complete disregard for accountability is nothing short of infuriating. At first, things appeared to go smoothly. The workers were professional, and the workmanship seemed decent. But the illusion of competence quickly disintegrated when it came time for the building inspection. The city inspector requires a letter from the project engineer verifying that the work is safe, sound, and compliant with code. 58 Foundations flat-out refuses to provide this basic validation of their work. Why won’t they stand behind their project? Are they hiding shoddy, substandard work? As a homeowner, I’m now saddled with the mess of an open permit and no resolution in sight. This is unacceptable. If a company won’t back their work with a simple letter, what does that say about their integrity—or lack thereof? Didn't expect this kind of run around from a well established professional firm, save yourself the frustration and inevitable regret. Choose a company that honors their commitments and respects their customers. Once upon a time, 58 Foundations may have been reputable, but their crumbling standards are now painfully obvious. Don’t let their negligence become your problem."

"Install done in 2023 and parts was under warranty. 2 years later it breaks and the company wants to charge to fix it. Product under warranty mean no charge to home owner. Not a reliable company. "

FAQs for radon gas testing projects in Saint Clair, 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.
