If you’ve tested your home and discovered elevated radon levels, you’re not alone. In Utah, where geology and climate create ideal conditions for radon gas to accumulate, mitigation is not just recommended—it’s essential.
But not all radon mitigation systems are created equal. Choosing the right one for your property depends on foundation type, soil conditions, and radon severity. In this guide, we’ll break down the most effective radon mitigation systems for Utah homes in 2025 and how to choose the best one for your situation.
Why Utah Homes Require Tailored Solutions
Utah’s housing stock ranges from older brick homes in Salt Lake City to luxury mountain cabins in Park City and new construction in Lehi and St. George. Radon levels—and how to control them—vary by foundation type, elevation, and even seasonal weather.
Mitigation systems must be selected based on the home’s structure, access points, and radon concentration levels measured during testing.
Top Radon Mitigation Systems for Utah Homes
1. Sub-Slab Depressurization (SSD)
Best for: Homes with basements or slab-on-grade foundations
This is the gold standard for most Utah homes. A suction pipe is inserted through the concrete slab into the soil beneath, where radon is collected and vented through a pipe system to the outside—typically above the roofline. A fan runs continuously to maintain negative pressure under the slab.
Benefits:
- Highly effective (reduces radon by up to 99%)
- Long-term reliability
- Discreet and quiet
2. Crawlspace Depressurization
Best for: Homes with exposed dirt or vented crawlspaces
This system involves sealing the crawlspace floor with a vapor barrier and installing a suction fan system to pull radon from beneath the membrane. The collected gas is then vented outside.
Benefits:
- Controls both radon and moisture
- Improves indoor air quality
- Ideal for older homes or cabins with crawlspaces
3. Passive Mitigation Systems
Best for: New construction homes
These systems use natural air flow (no fan) to draw radon from beneath the slab through a vent pipe to the roof. While required in many new Utah builds, they are often not sufficient on their own and need to be upgraded to active systems.
Benefits:
- Low energy cost
- Easy to activate with a fan if needed
4. Drain Tile Depressurization
Best for: Homes with existing perimeter drain systems
This method ties into the existing drain tile around the home’s foundation, using it as a pathway to collect and vent radon. It’s highly effective when integrated into the construction phase or during major renovations.
Benefits:
- Utilizes existing infrastructure
- Efficient for homes with heavy groundwater presence
Cost and Installation Time
- Most radon mitigation systems in Utah cost between $1,200–$2,500, depending on system type and home layout
- Installation usually takes 1 day, with minimal disruption
- All systems should be followed up with a post-installation radon test to verify effectiveness
Choose a Certified Radon Professional
A proper radon system is not a DIY project. It requires diagnostic tools, building code knowledge, and careful planning to avoid short-circuiting airflow or creating other indoor air quality issues. Always choose a certified radon mitigation company with experience in Utah soil and home types.
