Radon Mitigation & Testing
In Hyde Park, UT

Cache County is in EPA Radon Zone 2, moderate radon potential. The EPA predicts average indoor screening levels between 2.0 and 4.0 pCi/L. Many homes here still test above the 4.0 pCi/L action level, so the EPA recommends every home be tested. Cache County is in EPA Zone 2, the middle of the three predicted levels, along with most of Utah: 22 of its 29 counties. The only way to know your home's actual level is a radon test.

The EPA action level is 4.0 pCi/L, at or above that, the EPA recommends having a mitigation system installed. Because there is no known safe level of radon exposure, the EPA suggests considering mitigation between 2.0 and 4.0 pCi/L as well. The World Health Organization recommends acting at 2.7 pCi/L.

You have two options: hire a radon measurement professional from this page for a precise 48-hour monitor test, or use a do-it-yourself test kit from a hardware store or your state radon program. Short-term tests take 2–7 days; if the result is 4.0 pCi/L or higher, confirm with a follow-up test or move straight to mitigation.

Most single-family radon mitigation systems cost between $800 and $2,500 installed, with typical jobs around $1,200–$1,800. Those are national figures; we do not publish a price for Hyde Park, because the number that matters is the one a contractor gives you after looking at your foundation. Price depends on foundation type (basement, slab, crawlspace), house size, and how the piping has to be routed. 5 companies on this page cover Hyde Park, though only 2 are within 25 miles and the rest travel further. Two or three quotes is still worth getting, and a company driving an hour may price that in.

The standard fix is active sub-slab depressurization: a sealed pipe is inserted through the foundation floor, and a continuously running inline fan pulls radon-laden soil gas from under the house and vents it above the roofline, before it can enter your living space. Systems typically reduce radon by 80–99%, run on about as much electricity as a light bulb, and include a manometer so you can see it's working.

It depends on the state. Some states license anyone who measures radon for a fee or installs mitigation systems; others leave it to voluntary national certification. Certification and license details change over time, so check any company's current standing with the Utah radon office at 1-800-458-0145 before you hire.

Radon testing is a standard part of real-estate transactions in most of the country. Buyers: ask for a professional radon test during your inspection window, it takes about 48 hours. Sellers: testing (and mitigating if needed) before listing avoids surprises at closing. A mitigation system with documented low results is a selling point, not a liability.
