When to mitigate
The EPA recommends action when a confirmed radon test shows 4 pCi/L or higher. Many homeowners also choose to reduce lower levels for added peace of mind.
How mitigation works
Radon levels can be reduced by installing a mitigation system. The most common system uses sealed PVC piping and a fan to draw radon from below the home and vent it safely outside.
Every home is different, so the installation approach depends on the foundation, sump openings, slab conditions, utilities, and test results.
- Sub-slab and sump-based mitigation options
- Exterior vent and fan installation where appropriate
- Sealing of practical entry points such as cracks, drains, and sump openings
- System monitoring so homeowners can see that the fan is operating
- Free estimates before work begins
