Radon Mitigation Cost in Madison
Wisconsin's health department publishes an average price, which most states don't. Here's that figure, how it compares, and what to budget after the install.
Wisconsin DHS
$1,000 – $2,000
Wisconsin DHS says the average cost for a contractor to install a radon mitigation system is $1,000 to $2,000, varying with the home's size and design and the methods needed.1
Side by side
| Source | Price |
|---|---|
| Wisconsin DHS, average installed system1 | $1,000–$2,000 |
| National Radon Program Services, U.S. typical range2 | $800–$2,500 |
| Dane County test kit (Public Health Madison & Dane County)3 | $10 |
| Replacement fan, installed (EPA)4 | $200–$350 |
DHS frames the cost as roughly what you'd pay for other common home repairs, like painting or a new water heater.1
Why DHS says get three bids
With no state license, prices and quality vary more than in licensed states. DHS recommends contacting at least three certified companies for estimates so you can compare.1 EPA adds that the cheapest system can cost more to run, and that material quality affects how long it lasts.4
Already have a pipe?
DHS notes that in buildings with radon piping already installed, a contractor may be able to add a fan to turn the passive system into an active one.5 The University of Kentucky's BREATHE program puts activation at about $500–$600, far below a full install.6
