How a radon mitigation system works
Most Omaha homes are fixed with sub-slab depressurization. A contractor drills a hole through the basement slab, removes a little soil to create a suction pit, and connects a PVC pipe to a fan. The fan pulls soil gas from under the slab before it can enter the house and vents it above the roofline, where it disperses.
- Suction point: one or more holes through the slab, placed based on how air moves under your floor.
- Vent pipe: run inside (through a closet or garage) or outside along the house, ending above the roof edge.
- Radon fan: mounted outside the living space, usually in the attic, garage or on an exterior wall.
- Manometer: a simple U-tube gauge on the pipe that shows the system is pulling suction.
What to expect on install day
A typical single-family install takes most of a day. The installer will look at the slab, sump, foundation walls and where the pipe can run, then seal visible slab openings such as a sump pit or large cracks. After the system runs for at least 24 hours, a follow-up radon test confirms the result. Plan to retest every couple of years and after major renovations.

Choosing a radon contractor in Nebraska
Nebraska credentials radon measurement and mitigation professionals through the Department of Health and Human Services radon program. Before you hire anyone, ask to see their current Nebraska radon mitigation credential, ask what the estimate includes (fan, manometer, sealing, post-test) and ask about the warranty on the fan and on the radon reduction itself. Homes across the river in Council Bluffs fall under Iowa’s own certification rules.
