Radon Mitigation Readiness Checklist

Contact a certified professional or order a DIY test kit

Close windows and doors, avoid unusual ventilation 12 hours before test

Note home age, foundation type, basement configuration, previous tests

Check EPA radon zone map for your county and potential risk level

Learn about radon risks and EPA recommendations (4 pCi/L action level)

Obtain radon level readings and documented test results

If levels exceed 4 pCi/L or are borderline, plan for mitigation

Contact 2-3 certified contractors for cost estimates and system recommendations

Verify licenses, certifications, insurance, warranties, and customer reviews

Select contractor and book installation date that works for your schedule

Remove items from basement/crawlspace and provide work access

Be available during installation and provide access to all necessary areas

Understand where equipment is placed and how it operates

Get system warranty, operation manual, maintenance schedule, and invoice

Plan radon retest for 30 days after installation (typically included)

Get radon levels tested to verify system effectiveness (target: below 4 pCi/L)

Check for unusual sounds, odors, or pressure gauge indicators

Plan annual inspections and maintenance per contractor recommendations

Continue periodic testing to ensure system maintains effectiveness

File test results, warranties, receipts, and maintenance logs for future reference
