What should I do today and this week?
Confirm the high result before spending money. EPA says a short-term radon test is the first step, and a result of 4 pCi/L or higher should be followed by a confirmation test. Test in the basement or ground floor, since radon levels are often highest in the lowest part of a home.
Who should install the fix?
EPA says a home with elevated radon should be fixed by a professional trained to mitigate radon problems. EPA advises getting estimates from one or more qualified radon mitigation contractors before choosing a system. Kentucky guidance says mitigation systems are installed by certified radon mitigation professionals, not general home inspectors.
What should I check when hiring or switching a contractor?
Ask the pro for proof of licence and insurance. Look up the certifications through the state radon program or the national radon proficiency programs, NRPP and NRSB. Ask for a quote based on your specific house, because EPA says cost depends on how the home was built and how severe the problem is.
What happens after the system is installed?
Once the system is in, EPA recommends a follow-up test to confirm the level has dropped. An in-line fan is the standard way EPA says to activate a system in a home at 4.0 pCi/L or above. Keep the test results with your home records.
What to do next
- Order a follow-up radon test to confirm the first result; the Kentucky Radon Program offers free test kits to residents.
- Check the Kentucky Radon Program or NRPP/NRSB directories to verify the contractor's certification.
- Request a written quote that is based on your specific house and shows the sub-slab depressurization system scope.
- Ask the contractor for proof of insurance and licence before work begins, then schedule a post-mitigation test.
