Radon Testing, Mitigation Costs & Contractors in Virginia

Virginia's Indoor Radon Program provides state-specific radon maps, test guidance, professional-certification requirements, and consumer resources. High radon results have been found throughout the Commonwealth, so testing is appropriate regardless of region.

Testing your home

Test the lowest livable level and follow closed-house conditions for short-term testing. Virginia recommends long-term testing when practical and requires qualifying professional testers/mitigators to hold current national certification.

Free or low-cost test-kit information

VDH says a limited supply of short-term kits is available for a $4 shipping fee until supplies run out. Because fulfillment can change, verify the live ordering page immediately before launch.

Programs and inventory can change. Confirm current availability with the listed agency before relying on an offer.

Mitigation cost planning

Estimate only: a professionally installed residential radon mitigation system often falls in a broad $1,200–$3,500 range, but the final price can be lower or higher. Foundation type, crawlspaces, finished basements, multiple suction points, fan/pipe routing, electrical work, permits, diagnostics, and post-mitigation testing can materially change the quote. Use local written bids rather than treating this range as guaranteed pricing. State reference: VDH consumer guidance cites professional mitigation roughly from $800 to $2,500, with complex homes potentially higher; use current local bids.

A test result provides important context, but it does not directly increase the modeled price.

Virginia rules and public resources

Verified: Virginia Code §32.1-229.01 requires professional radon testers and mitigators operating in Virginia to hold current certification from NRPP or NRSB. Verify the individual's current certification before displaying that status.

EPA radon-zone context

VDH reports numerous Zone 1 and Zone 2 counties/cities in Virginia, but the only way to know a specific indoor level is to test the building.

Testing is the only way to know. EPA radon zones are broad planning tools. Never use a zone, county, ZIP, or map to predict the radon level of a specific home or to decide that testing is unnecessary.

Frequently asked questions

Should every home in Virginia be tested for radon?

Testing is the only way to know the radon level in a specific Virginia home. Maps, county averages, a neighbor's result, and foundation type cannot replace a properly conducted test.

What does a result of 4 pCi/L mean?

EPA recommends taking action to reduce radon at 4 pCi/L or higher and suggests considering action between 2 and 4 pCi/L. The action level is not a line between safe and unsafe; long-term risk generally increases as exposure increases.

How much does radon mitigation cost in Virginia?

Pricing varies by the home and the system design. RadonCostGuide uses broad planning estimates only; foundation type, crawlspaces, finished areas, suction points, electrical work, permits, diagnostics, and post-mitigation testing can all affect the final quote.

How do I find a radon professional in Virginia?

Start with the state radon program and the NRPP/NRSB directories where appropriate. Independently confirm current credentials, insurance, scope of work, permits, warranties, service area, and pricing before hiring.

Are free or low-cost radon test kits available in Virginia?

VDH says a limited supply of short-term kits is available for a $4 shipping fee until supplies run out. Because fulfillment can change, verify the live ordering page immediately before launch.
