Radon fans run continuously for five to ten years, then fail — sometimes loudly with bearing grind, sometimes silently with a manometer going level. Replacement is a same-day swap on the existing riser, followed by a retest, not a new system.
Reasons to schedule this service

This service may be the right fit when one of these situations sounds familiar:
- the fan is noisy
- the manometer reading changed
- the system is old or damaged
What matters for Madison properties
A dead fan matters most exactly when Wisconsin houses are sealed tightest. A February failure can hold a Madison basement at pre-mitigation levels for months if nobody looks at the gauge — which is why the monthly manometer glance is the habit worth building. Columns level: check plug, switch, breaker; then book the swap.
What affects the estimate
- fan size
- pipe condition
- electrical connection
- test history
- weather exposure
How the work usually goes

A replacement visit runs:
- Test Result Review: Review the radon test result, test date, foundation layout, basement use, and any real-estate deadline.
- Foundation And Sump Check: Check slab areas, sump pits, drain tile, crawl spaces, pipe routes, fan locations, and discharge options.
- System Design Planning: Plan the mitigation system, sealing details, electrical needs, fan placement, and retest timing.
- Pipe Fan And Sealing Work: Install or repair the pipe, fan, suction point, sump cover, crawl-space barrier, or sealing work.
- Retest And Maintenance Guidance: Review manometer readings, labels, maintenance notes, and when the home should be tested again.
