I live in a brand-new Lehi home. Do I still need to test?

Yes. Some new homes include passive radon piping, which can often be activated with a fan if a test comes back high.

My radon test came back high during a home sale. What now?

Radon Mitigation in Lehi, UT

Radon and Lehi homes

Lehi has grown fast. Much of the city is newer construction around Thanksgiving Point, Traverse Mountain and the Silicon Slopes tech corridor along I-15, alongside older homes near historic Main Street.

Many Lehi homes have basements, from older homes downtown to newer two-story houses in master-planned neighborhoods. A newer house is not automatically a low-radon house. Radon comes from the soil, and how a home is built over it matters more than its age.

Lehi tip: If you are buying or selling, a radon test is often part of the inspection period, and a high result can lead to a mitigation request in negotiations.

Should you test your Lehi home?

Yes. The Utah County Health Department says one out of three Utah homes has unsafe radon levels, and recommends testing at least every five years or after a remodel. The EPA radon zone map places Utah County in Zone 2 (moderate potential), but EPA is clear that the map can't predict any single home and that every home should be tested. Radon in Lehi can differ from house to house, even on the same street.

Test the lowest level of your home that you use as living space. The colder months are the best time to test. You can order a discounted short-term kit through radon.utah.gov, or borrow a professional continuous monitor from the Utah County Health Department's Provo office from October through March for a small fee.

What your result means

Below 4 pCi/L: below the EPA and Utah action level. Retest every two to five years.
4 to 6 pCi/L: Utah DEQ suggests a long-term test to confirm.
Above 4 pCi/L: EPA and Utah suggest mitigation. Contact a certified professional.

How radon mitigation works in Lehi

According to Utah DEQ, a typical system uses a roughly five-inch hole in the foundation, four-inch PVC pipe and an exhaust fan outside or in the attic to pull radon from under the home and vent it away. DEQ estimates the cost at around $2,000, plus about $8 to $10 a month in electricity, with a fan replacement after about 15 years. Get a retest after the system has run for at least 24 hours, and check the manometer gauge regularly. See our radon mitigation cost guide for what changes the price.

Choosing a contractor

Utah requires mitigation to be done by a licensed contractor with NRPP or NRSB certification. Utah DEQ suggests getting three bids and looking for diagnostic testing, a warning device, a post-install retest and a written guarantee to reach 4 pCi/L or below. When you request a quote, we pass it to an independent, licensed, certified contractor who serves Lehi.
