"Jack and his crew were phenomenal. I cannot say enough good things. They did an outstanding job remediating/removing asbestos from our basement. Jack is reliable, professional, has tremendous expertise in the field and communicated with us at every step of the process. He also helped bring me back down to earth because I was so nervous about the asbestos. Truly above and beyond what I could have ever expected. We will certainly hire ACI-Tech again should we have any needs in the future."

We’re Jim and Mike Allen, brothers and co-owners of TermiGuard Services and Fenwick Building & Renovation. With our 50+ years of combined experience, we can promise you that you're in good hands. One of the biggest challenges we face as homeowners is finding the right contractor to deal with issues which arise – one who has the requisite knowledge, skills, and experience. A contractor who will answer your calls and then do what they say they’d do, when they said they would. A contractor you can trust, and who will actually give you a no-nonsense warranty on his/her work. We’ve built TermiGuard Services & Fenwick to be effectively different from the rest – embracing and living the principles and values we grew up with – treating people the way we’d want to be treated. And frankly, we’re tired of how so many other companies treat customer service as unimportant and how they take customers for granted. As consumers ourselves, we’ve felt the pain from the evident lack of caring and regard for the concept of old-fashioned, customer-centered service. To that end, we offer you a family of home services including, real estate repairs, pest, termite & wildlife control, water intrusion inspections, mold treatment, waterproofing, structural & foundation repairs, property & water damage restoration, and crawl space encapsulation services – to name just a few… Bottom line – we’re first aid for your home or building, and we’re dedicated to providing you healthier living…

FAQs for radon gas testing projects in Swarthmore, 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.
