How Much Does Radon Mitigation Cost?

If you’ve recently received a radon test result – or you’re just starting to research radon – you’re probably asking the same thing most Utah homeowners ask first:


How much does radon mitigation cost in Utah?

The short answer: most professionally installed radon mitigation systems in Utah cost between $1,600–$2,300. But every home is different, and radon systems are custom-built based on your home’s layout, foundation, and venting options. At Utah Radon Defense, we believe homeowners deserve honest, upfront pricing – not vague answers or guesses.

Why Radon Mitigation Costs Vary

No two homes are exactly alike. Even homes next door to each other can require completely different mitigation systems depending on:

  • Foundation type
  • Home layout
  • Soil conditions
  • Pipe routing options
  • Venting location
  • Existing passive systemsa

That’s why accurate pricing requires seeing the home in person. If a company gives you an exact quote over the phone without evaluating your home first, that’s usually a red flag.

Radon Mitigation System Cost in Utah

Typical Range: $1,600 – $2,300

A radon mitigation system safely pulls radon gas from beneath your home and vents it outside before it can enter your living space. This is the most effective long-term solution for elevated radon levels.

What affects the cost?

  • Foundation type: Basement, slab, and crawl space homes all require different approaches.
  • Pipe routing: Interior routing inside walls is more labor-intensive than exterior routing.
  • Home size & layout: Larger homes or homes with multiple zones may need additional suction points.
  • Venting method: Roof exits and sidewall exits can impact installation complexity.
  • Optional upgrades: Items like fan covers, continuous monitoring systems, or attic access can increase cost.

Most Utah Radon Defense systems fall within this range with no surprise charges after installation.

Homes with crawl spaces or unusually complex layouts may cost more, but we communicate everything clearly before work begins.

Adding a Fan to a Passive Radon System

Typical Range: $500 – $800

Many newer Utah homes already have a passive radon system installed by the builder.

That means the vent pipe is there – but no active fan. Unfortunately, passive systems alone often do not reduce radon levels enough.

Adding a radon fan converts the system into an active mitigation system that actually pulls radon gas from beneath the home.


Cost factors include:

  • Fan type
  • Existing system compatibility
  • Electrical needs
  • Accessibility
  • Installation labor


Most fan additions are straightforward and fall toward the lower end of the range.

Radon is the leading cause of lung cancer for non-smokers in the United States and the second leading cause of lung cancer for smokers. It is estimated that radon gas is responsible for as much as 14% of all lung cancers worldwide with higher rates among smokers. The Surgeon General and the US Environmental Protection Agency (EPA) recommend testing for radon gas along with mitigation when high levels are present. According to EPA recommendations, radon levels exceeding 4 picocuries per liter (pCi/L) pose a health risk and should be mitigated. The presence of radon gas at 4 pCi/L or above is concentrated in your home at levels 10 times higher than outdoor air levels. The EPA also notes levels below this measure can still pose some risk as does the World Health Organization, which recommends mitigation if radon levels exceed 2.7 pCi/L. Technically, no amount of radon gas levels are considered to be safe. Any presence of radon gas increases your risk of getting cancer. Even a reading of 1 piCi/L is equivalent to smoking 2.5 cigarettes daily. Radon exposure is responsible for 21,000 lung cancer deaths annually, including people that have never smoked. That’s more than twice the number of people that are killed in drunk driving accidents, four times those drowning, and eight times the number of people killed in house fires.

Radon is often called the silent killer because it is a colorless and odorless gas. Radon is radioactive carcinogen, and it’s dangerous. Radon occurs naturally as it is released from rock, soil, or water and can accumulate within your home. Exposure to radon increases your risk of getting lung cancer. It’s the number two cause of lung cancer overall in the U.S. and the number one contributor to lung cancer for those that do not smoke. Since you can’t see it, smell it, or taste it, the only way to detect it is with radon testing.
