The proven fix for high radon in basement homes
Sub-slab depressurization (also called active soil depressurization) is the standard, EPA-recognized method for lowering radon in homes with basements or slab floors, which describes most homes in the Omaha metro.
What's included in a typical system
- One or more suction points through the slab, or a sealed sump lid with a suction port
- Schedule 40 PVC pipe from the suction point to the fan
- An inline radon fan, usually mounted outside or in the attic or garage (not in living space)
- Exhaust discharged above the roof edge, away from windows
- Sealing of accessible cracks, floor-wall joints, and openings
- A manometer to show the system is running
- System labeling and a post-mitigation test
Questions to ask
- Will you do a diagnostic (pressure field) test to choose the suction point?
- Where will the pipe run and fan be located?
- What result do you guarantee, and what if it isn't met?
- What's the warranty on the fan and labor?
- Are you licensed in Nebraska (or Iowa)?

Frequently Asked Questions
Can the pipe run inside the house?
Yes. Interior routing through a closet or garage to the attic is common when homeowners prefer not to see exterior pipe, though it may cost more.
Will I hear the fan?
Fans mounted outside or in the attic are usually quiet indoors. Some airflow noise near the exhaust is normal.
