Radon Mitigation Systems Explained
What a code-compliant radon mitigation system includes, how active sub-slab depressurization works, and what to expect from a professional Ohio installation.
The most effective radon mitigation method is active sub-slab depressurization — a sealed fan-and-vent system that continuously pulls radon from below your foundation and releases it safely above the roof.
Suction Point
A sealed pipe is set into the sub-slab area to collect radon gas.
Inline Fan
A continuous radon fan maintains negative pressure beneath the slab.
Roofline Vent
Radon is exhausted safely above the roofline, away from windows.
What a Quality Install Looks Like
- ✓Sealed foundation penetrations no radon re-entry paths.
- ✓Properly sized fan matched to your home for quiet, efficient operation.
- ✓System monitor a manometer so you can confirm it is working at a glance.
- ✓Post-install verification test we confirm levels dropped below 4.0 pCi/L.
