What should I do this week with these three quotes?
Ask each bidder for a written quote that lists the system type, number of suction points, fan model and warranty terms. Confirm each company's Kentucky radon certification before you sign. Compare the quotes line by line rather than by price alone.
Why is one radon quote so much lower?
A very low bid can mean fewer suction points, a smaller or lower-grade fan, or missing sealing and labeling work. EPA says costs vary with home size, design and the reduction method needed. Ask the low bidder to show exactly what is included.
What essential components should a valid installation include?
A standard sub-slab depressurization system uses a suction pit or pipe through the slab, PVC piping, and an exhaust fan vented above the roofline. EPA says the system should be installed by a qualified contractor experienced in radon reduction methods. Ask for these components in the written quote.
How do I check that a contractor is legitimate?
Kentucky law requires radon mitigation contractors to hold appropriate certification, and no one may claim to be certified unless they are. Ask the pro for proof of licence and insurance. Confirm the certification through the Kentucky radon program office at 502-782-2782.
What to do next
- Request a written quote from each bidder that lists suction points, fan model and warranty.
- Verify each company's Kentucky certification and ask for proof of licence and insurance.
- Confirm the contract states the time needed to complete the work.
- Schedule post-mitigation clearance testing at least 24 hours after start-up, within 30 days, as HUD advises.
