How It Works
Radon is a naturally occurring gas that enters your home from the soil. Here's how it gets in — and how we get it out.

Without a mitigation system, radon rises from the soil into your home. With one, it's drawn out beneath the slab and vented safely outside.
How Radon Enters Your Home
Radon gas forms naturally in soil and rock as uranium breaks down. It migrates upward through the ground and enters homes through openings in the foundation — including basement floor cracks, sump pump openings, crawl space floors, and gaps around pipes.

How Mitigation Works
Sub-slab depressurization is the most effective radon mitigation method. We create a collection point beneath your foundation, run a PVC pipe up through the home, and install a quiet fan unit that continuously draws radon from the soil and vents it safely outside — above the roofline, away from windows.
