What should I do today if my radon levels came back up?
Retest before you hire anyone, since testing is the only way to know the current level. Kentucky's radon program at (502) 564-4856 can point you to free short-term test kits through some local health departments. If the result is at or above 4.0 pCi/L, the home needs mitigation until levels drop below that threshold.
What should I check when hiring or switching contractors?
Kentucky law requires mitigation contractors to hold board-approved proficiency certification and general liability insurance. Mitigation work must be conducted under the direct supervision of a mitigation contractor. Ask the pro for proof of licence and insurance before signing anything.
What are signs a radon system was installed improperly?
Levels that rise again after a fix often point to a system that was not sized or sealed correctly for the home. Retesting after installation is the check that shows whether the fix worked. The University of Kentucky recommends testing every two years, especially when switching contractors.
How much does a Kentucky radon fix cost compared with new construction?
The University of Kentucky reports typical existing-home mitigation at $1,200 to $2,500 depending on home size. Radon-resistant measures in new construction cost about $600 to $800 for a single-family home. The EPA says costs vary by technique, materials and severity.
What to do next
- Order a short-term radon test kit from your local health department or the Kentucky Radon Program at (502) 564-4856, and test before rehiring anyone.
- Ask the pro for proof of Kentucky board-approved proficiency certification and general liability insurance before you sign.
- Request a written quote that names the system type, the materials and a post-installation retest to confirm levels are below 4.0 pCi/L.
- Schedule a retest every two years, or after any change in contractor, to confirm the fix still works.
