Virginia Radon Mitigation Cost by County, Foundation, and Rules
Compare typical local price ranges for basement, slab, and crawl space systems. Use the state-level ranges first, then open your county when you need a local estimate after a confirmed radon result.
Fastest Start
Use ZIP Instead of Scrolling
If you know the property ZIP, jump straight to the right county estimate instead of browsing the full state list.
Cost Basics
Foundation & Result Ranges
Use the national cost guide if you need basement, slab, crawl-space, or 4.0+ result context first.
Validate the Risk
Check VA Radon Levels
If you do not have a confirmed radon result yet, review EPA zone context before you compare mitigation pricing.

Basement
$925-$1643
Use this when the home has a basement or lowest-level slab that supports a standard sub-slab suction system.
Slab-on-Grade
$873-$1538
Slab homes can price differently when finished space, routing, or core drilling complicates the system path.
Crawl Space
$1430-$2600
Crawl-space jobs can move higher when vapor-barrier sealing, access, and sub-membrane suction add labor.
