Radon mitigation in the Salt Lake Valley
Licensed contractors we refer handle the whole job, from design through the post-install test:
Basements and slab homes
A pipe and fan pull radon from under the floor and vent it above the roof. How sub-slab systems work →
Crawl spaces
A sealed membrane over the dirt floor with suction underneath, EPA's most effective crawl-space method. Details →
Buying or selling
A written bid in time for your due-diligence deadline, and a retest before closing. Home-sale guide →
Fans, checkups and new homes
Fans typically last about 15 years, and a builder's passive pipe usually just needs a fan. New construction →
How it works
- Call (801) 854-8750 with your test result, city and foundation type.
- We connect you with a licensed contractor who serves your area, for a written quote.
- Installation usually takes a day: a suction point, a pipe, a fan outside living space, and a gauge so you can see it's working (Source: EPA). Retest afterward, then every two years (Source: Utah DEQ).
What it costs
A typical Utah system costs about $1,800–$2,000 (Source: Utah DEQ), plus $8–$10 a month to run the fan. Slab and basement homes with one suction point usually cost less; crawl spaces, combination foundations and finished basements usually cost more. Cost factors and estimator →
Is radon common here?
Yes. In Utah's state test data, 38.6% of short-term tests in Salt Lake County (2006–2019) were at or above EPA's 4 pCi/L action level, and northeast Sandy averaged 7.0 pCi/L (Source: Utah IBIS). Nationally, EPA estimates about 1 in 15 homes is that high (Source: EPA). Radon levels by area →
Good to know in Utah
Licensing
Since 2009, radon systems must be installed by a licensed contractor (Source: Utah DEQ). NRPP certification is recommended but not required; a 2026 bill to require it failed (Source: bill tracker). Licensing vs. certification →
Home sales
Sellers aren't required to fix radon in Utah. It's negotiated: a seller-installed system, a credit, or funds held at closing (Source: Utah DEQ). Walkthrough →
Haven't tested yet?
Utah DEQ sells test kits for about $11 including the lab fee (Source: Utah DEQ). Test your lowest lived-in level with the house closed up. Testing guide →
Get more than one bid
Utah DEQ suggests three (Source: Utah DEQ). Every contractor we refer is licensed in Utah, and you're never obligated to hire them. How we work →

Common questions
Is 2.7 pCi/L safe? EPA says no level is completely safe and recommends considering a fix between 2 and 4 (Source: EPA).
Does opening windows fix it? Only for a while: levels typically return within about 12 hours of closing up (Source: EPA).
Is there financial help? Qualifying Salt Lake County families may get help from Green and Healthy Homes (Source: Utah DEQ).
