Radon mitigation is highly effective in Utah homes, typically reducing radon levels by up to 99 percent when installed correctly by a certified professional. Most systems bring levels well below the EPA’s recommended action level of 4.0 pCi/L within 24 to 48 hours of activation.
What Is Radon and Why Is Mitigation Necessary?
Radon is a radioactive gas that comes from the natural decay of uranium in soil and rock. It seeps into homes through:
- Cracks in the foundation
- Gaps in floors or walls
- Crawl spaces and sump pits
Radon is odorless and invisible, but long-term exposure increases the risk of lung cancer. Utah is considered a high-radon state, with nearly 1 in 3 homes testing above safe limits.
How Radon Mitigation Systems Work
The most common method is called sub-slab depressurization, which involves:
- Sealing major entry points
- Installing a vent pipe through the foundation
- Using a fan to pull radon gas from beneath the home
- Venting it safely outside above the roofline
The system runs continuously and is quiet and energy-efficient.
How Quickly Does Radon Mitigation Work?
Most homeowners see a dramatic drop in radon levels within 1 to 2 days of installation. A follow-up test confirms that levels are reduced below the EPA limit.
How Long Does a Radon Mitigation System Last?
With proper maintenance, a system can last 10–20 years. The fan is the most common part to replace, typically every 7–10 years, depending on usage and location.
Does Radon Come Back After Mitigation?
If the system is working and the fan is running, radon will remain at safe levels. However, it’s smart to test your home every 2 years to confirm that the system is still effective—especially after major renovations or foundation work.
Is Radon Mitigation Worth the Cost?
Yes. In Utah, a typical system costs $1,000–$2,000. When you weigh that against the risk of long-term health problems or failed home inspections during resale, it’s a worthwhile investment.
Plus, many Utah buyers now request radon testing as part of pre-purchase inspections. A home with a working mitigation system may sell faster and with fewer issues.
