What Is Radon Mitigation?
Radon mitigation is the process of reducing elevated radon gas concentrations inside a home or building to safe levels. The EPA recommends taking action whenever indoor radon levels reach 4 pCi/L or higher — and in Utah, levels above that threshold are common due to the state's uranium-rich soil and geology.
The most effective and widely used method is called Active Soil Depressurization (ASD). A licensed technician installs a system of pipes and a continuously running fan that draws radon gas from beneath your foundation and vents it safely outside before it can accumulate indoors. The system creates a slight negative pressure beneath the slab or crawl space, which redirects radon away from your living areas.
Utah's geology presents a specific challenge. The Wasatch Front and surrounding regions sit on soils with elevated concentrations of naturally occurring uranium and radium — both of which decay into radon gas. Homes across Salt Lake, Utah, Davis, Weber, and Cache counties consistently test above the EPA action level, making professional mitigation not just advisable, but often necessary. You can learn more about radon risk levels at the EPA's radon information page.
What to Expect: Our Mitigation Process
Step 1 — Assessment Before any installation begins, we conduct a thorough assessment of your home's foundation type, construction, and current radon readings. This determines the exact system design your home requires. No two homes are identical, and a system designed for a poured concrete basement differs from one designed for a crawl space or slab-on-grade foundation.
Step 2 — System Design Based on the assessment, we engineer a mitigation system specific to your home's structure. We determine suction point locations, pipe routing, and fan specifications to ensure the system achieves maximum pressure field extension beneath your foundation.
Step 3 — Installation Most residential installations are completed in a single day, typically three to five hours. Our technicians core-drill a suction point through your foundation, route PVC piping to the exterior or attic, and install a radon fan rated for your home's specific sub-slab conditions. The system runs continuously and quietly.
Step 4 — Post-Installation Testing After installation, we conduct a follow-up radon test — typically a 48-hour continuous measurement — to confirm the system is performing as designed. We do not consider the job complete until your radon levels are verified to be below the EPA action level.
Step 5 — Documentation and Warranty You receive a complete report documenting pre- and post-mitigation radon levels, system specifications, and warranty information. All systems installed by Intermountain Radon Services include a transferable limited lifetime warranty on workmanship and components.
Foundation Types We Work With
Every Foundation Type. One Certified Team.
Radon mitigation is not one-size-fits-all. The correct system design depends entirely on how your home was built.
Basement Foundations — The most common foundation type along the Wasatch Front. We install sub-slab depressurization systems that draw radon from beneath the concrete floor, routing exhaust to the exterior above roofline level.
Slab-on-Grade — Homes with no basement require careful suction point placement to achieve adequate pressure field extension across the full slab. We conduct diagnostic testing before finalizing the installation plan.
Crawl Spaces — Crawl space homes require a different approach. We install a heavy-duty vapor barrier sealed to the foundation walls, combined with a sub-membrane depressurization system that vents radon from beneath the liner. This also reduces moisture intrusion as a secondary benefit.
Combination Foundations — Many Utah homes include a mix of foundation types — a partial basement with a crawl space or slab section. We design systems that address all areas under one installation.
How long does radon mitigation take?
Most residential installations are completed in one day, typically three to five hours. After installation, we schedule a follow-up test 48 hours later to confirm results. From initial assessment to verified results, the full process is generally completed within one to two weeks.
How much does radon mitigation cost in Utah?
Residential radon mitigation in Utah typically ranges from $1800 to $6,500 depending on foundation type, home size, and system complexity. We provide a detailed quote after the initial assessment — there are no hidden fees, and the quoted price includes post-mitigation testing and all documentation.
Will a mitigation system completely eliminate radon?
No mitigation system can reduce radon to zero, as radon is naturally present in outdoor air at low concentrations. However, properly designed active soil depressurization systems routinely reduce indoor radon levels by 90–99%, bringing levels well below the EPA action level of 4 pCi/L. Our post-installation testing verifies your results before we close the job.
Do I need to leave my home during installation?
No. Installation does not require you to vacate your home. There is some noise from drilling and equipment, but there are no hazardous materials or ventilation requirements that would displace your household during the process.
How do I know the system is working after installation?
Every system we install includes a visual indicator — a U-tube manometer mounted on the pipe — that shows whether the fan is maintaining negative pressure. We also recommend annual radon testing to confirm continued performance. If levels rise, we service the system at no charge under our warranty.
Is radon mitigation covered by homeowners insurance?
Radon mitigation is generally not covered by standard homeowners insurance policies, as it is considered a preventive measure rather than damage repair. Some home warranty plans include coverage — we recommend checking your policy directly. We do offer financing options; contact us for details.
