Our only job is to tell you the truth about your home’s air.
How Radon Enters Your Home
Your home naturally moves air. As warm air rises and escapes through the upper levels, it creates lower pressure near the foundation. This pressure difference — known as the stack effect — can pull radon gas into the home through cracks and openings.
Many Philadelphia-area homes — especially older rowhomes and properties with aging stone or masonry foundations — can develop entry points that allow radon gas to enter from beneath the structure. Professional Philadelphia radon testing helps identify elevated indoor radon concentrations commonly found in older Pennsylvania homes.
Invisible & Odorless
Radon cannot be seen, smelled, or tasted, making professional radon testing the only reliable way to identify elevated indoor concentrations.
Radon Enters Through Foundation Cracks
Radon gas can enter through basement floor cracks, sump pits, pipe openings, and porous foundation gaps.
A Serious Health Risk
Radon exposure is the second leading cause of lung cancer in the United States, causing 21,000 deaths annually.
