“How much is a radon system?” is usually the first question after a high test. The honest answer is that it depends on the house. This guide explains what goes into the price so you can compare estimates with confidence.
The typical range
The EPA describes the cost of radon mitigation as similar to many common home repairs. National figures for a standard sub-slab system in a single-family home are commonly cited at roughly $800 to $2,500, with most homes toward the lower half of that range. Omaha estimates vary with the factors below, so treat any number you see online as a starting point, not a quote.
What raises or lowers the price
- Foundation type. A single open basement is usually simplest. Crawl spaces, slab additions and mixed foundations can need extra suction points or a membrane. See crawl space radon mitigation.
- What’s under the slab. Gravel lets air move freely, so one suction point can cover a large area. Tight clay soil may need more points or a stronger fan.
- Pipe routing. Exterior routing up the side of the house is often less expensive. Interior routing through a closet or garage looks cleaner but can take more labor.
- Finished basements. Finished walls and floors limit where the pipe can go and how much of the slab can be reached.
- Sealing. Sump pit lids, large cracks and floor drains may need sealing as part of the job.
- Electrical. The fan needs a power source near where it is mounted.
What a fair estimate should include
- The number and location of suction points
- Fan model and where it will be mounted
- Pipe route, inside or outside
- Sealing work (sump lid, cracks, openings)
- A manometer or other system monitor
- A post-mitigation radon test
- Warranty terms for the fan and for the radon reduction
- The installer’s current Nebraska radon mitigation credential
Running costs
A radon fan runs continuously, so it adds a small amount to your electric bill, and fans eventually need replacing. Ask your installer what fan they plan to use and what similar systems typically draw. See radon fan replacement for signs a fan is failing.
Getting an estimate
The fastest way to a real number is a free written estimate based on your house. Request one here and include your test result, foundation type and whether the basement is finished.
