Radon Testing for Home Sales

Why radon comes up in almost every Utah home sale

Utah has some of the highest radon levels in the country, and most buyers here test for it during the inspection period. A high result is common — and it's a known, fixable issue, not a reason to walk away. What matters is getting a reliable test, understanding the number, and having a clear plan if it comes back high.

How it works in a transaction

1. Test during the inspection period. A short-term test or continuous monitor is placed in the lowest lived-in level of the home. Results typically come back in 2 to 7 days — fast enough to fit inside most inspection windows.
2. Read the result together. We explain what the number means against the EPA action level of 4.0 pCi/L, in plain language, so both sides are working from the same facts.
3. Mitigate before closing, if needed. If the level is at or above 4.0 pCi/L, a mitigation system can usually be installed before closing, with a retest to confirm the level came down.

Who pays for the test and the fix?

There's no rule — it's negotiable between the buyer and seller, like any other inspection finding. Sometimes the buyer orders the test and the seller pays for mitigation; sometimes it's the other way around. What we do is give both sides a clear number and a clear quote, so the negotiation is about facts, not guesses.

For buyers

If you're buying, get the test. A home's radon level isn't visible in a walkthrough, and it isn't something the seller is required to know — if they never tested, they honestly don't know. A test during inspection is cheap insurance, and a high result is leverage for a fix, not a deal-breaker.

For sellers

If you're selling, testing before you list removes the surprise. A low result is a selling point; a high result is a fix you can make on your own schedule instead of under a closing deadline. If a buyer's test comes back high, we can usually install a system and retest before closing — tell us your closing date in the form below and we'll tell you honestly whether the timeline works.

The home already has a mitigation system — do we still test?

Yes. A system can stop working without anyone noticing — a fan can fail quietly — and a test is the only way to confirm levels are actually low. If the system is running and levels are low, the test just confirms what everyone hoped. If not, we can inspect and repair the system.
