Radon Mitigation Cost in Utah (2026)
Utah's Wasatch Front and mountain geology create real radon risk — with Salt Lake and Utah Counties frequently testing above 4 pCi/L. Costs run $1,000–$2,600.
Utah Radon: The Wasatch Front Risk
Utah doesn't make the national news for radon the way Iowa or Colorado does, but the Wasatch Front corridor — home to most of Utah's population — sits directly on uranium-bearing granite that drives meaningful radon exposure.
Salt Lake County, Utah County (Provo/Orem), Davis County, and Cache County (Logan) all see a significant percentage of homes testing above 4 pCi/L. The state average is approximately 5 pCi/L, with some Wasatch Front areas averaging considerably higher.
What Mitigation Costs in Utah
| Foundation Type | Typical Cost |
| Slab-on-grade | $1,000–$1,800 |
| Basement (unfinished) | $1,100–$2,000 |
| Basement (finished) | $1,400–$2,600 |
| Crawl space | $2,500–$6,000 |
Utah's mountain west market is mid-priced — more expensive than the Midwest, cheaper than coastal states. The Salt Lake metro has solid contractor competition.
Regional Breakdown
Salt Lake City / Salt Lake County: Best contractor availability in the state. Multiple certified mitigators competing for business. Standard basement: $1,100–$2,000. Getting 2–3 quotes is easy and worth doing.
Provo / Orem (Utah County): Similar market dynamics to Salt Lake. Uranium County is aptly named — this area has some of the highest average radon in the state. Expect $1,100–$2,100.
Ogden / Davis County: Slightly smaller market but still competitive. Standard jobs: $1,100–$2,000.
St. George / Washington County: Lower radon risk than northern Utah, but not radon-free. Fewer certified contractors. Budget $1,200–$2,400.
Rural Utah: Very limited contractor availability outside the Wasatch Front. Scheduling windows can be long. Budget for travel fees and add 20–25% over metro rates.
Utah's Passive Radon Systems
Many Utah homes built between roughly 1990–2010 in master-planned Wasatch Front communities were constructed with passive radon rough-in systems. These include:
- A 4-inch PVC pipe stubbed out through the roof
- A gas-permeable layer below the slab
The problem: Passive systems alone reduce radon by only 30–50% on average. If your rough-in pipe is there but radon levels are still elevated, adding a fan (active sub-slab depressurization) is the fix.
Good news: Converting a passive system to active is the cheapest mitigation job in the industry — typically $300–$600 since the pipe is already installed. If you have a passive system stub-out, get it tested before assuming it's working.

Frequently Asked Questions
Does Utah have high radon?
Yes, particularly along the Wasatch Front. Salt Lake County, Utah County, Davis County, and Cache County all have significant radon risk. The uranium-bearing granite of the Wasatch Range is the primary source. Utah averages roughly 5 pCi/L statewide.
How much does radon mitigation cost in Utah?
Most Utah homeowners pay $1,000–$2,600 for a standard system. Salt Lake City and Provo/Orem have solid contractor markets. Smaller markets like St. George, Cedar City, and rural areas have fewer options and may cost more.
Does Utah have a radon program?
Yes. The Utah Radon Program through the Utah Dept of Environmental Quality provides testing resources and certified contractor lists. Visit radon.utah.gov or call 801-536-4250.
Are newer Utah homes radon-safe?
Not automatically. Many newer Utah homes — especially those built in the 1990s and early 2000s in Wasatch Front communities — were built with rough-in radon mitigation piping but no fan. This passive system often doesn't reduce radon to safe levels. Adding a fan to an existing passive system typically costs $300–$600.
