What should I do today if my radon contractor stopped responding?
Stop waiting on the first contractor. Call at least 2 to 3 other certified radon mitigators and ask when they can come out. The EPA advises getting more than one estimate before hiring anyone.
How do I check whether a new contractor is qualified?
Kentucky law says no one may conduct radon mitigation without proper certification. Ask for proof of certification and check with the state radon contact to confirm Kentucky's requirements. Verify experience and references too.
What should a new contractor explain before starting?
A contractor should explain what the work involves, how long it will take, and exactly how the radon reduction system will work. Compare written estimates from at least 3 bids to understand the price range.
What if someone else installed the system I now need fixed?
A local pro can take over an existing system installed by another provider. Ask whether the pro will inspect the current system, including the fan, before quoting repairs. Replacing a radon fan typically costs $200 to $350 including parts and labor.
