What should I do today if my radon system was installed with no follow-up?
Start by testing your home's radon level again. Kentucky residents can request a free short-term test kit from a local health department or through the Kentucky Radon Program. Results take 2 to 90 days, and the new result shows whether the current system is working.
How do I verify a new radon contractor before hiring?
Verify Kentucky Board of Radon Safety certification first. Ask for the professional's name and NRPP certification number. Compare licensed pros who honor warranties and provide documented follow-up, not just installation.
What should the new written quote include?
EPA advises getting an estimate from one or more qualified radon mitigation contractors before hiring. The quote should reflect your home's size, layout and the reduction method needed. Kentucky policy also requires post-installation testing and an ongoing maintenance plan.
What rights do I have if the old system was installed improperly?
Kentucky law authorizes the state radon board to inspect mitigation installations. The board can act if a system was not built or installed to the applicable standards. Keep your old contract and invoices to share with the new pro and the board.
