High radon is common. It’s also fixable.

Roughly 1 in 15 homes tests high. The good news: a mitigation system lowers it reliably.

  • Odorless and invisible — only a test reveals it
  • Comes up from the soil under your home
  • A vent system removes it safely
The fix

One quiet system. Cleaner air.

We draw radon from beneath your slab and vent it safely above the roof.
