Most calls start one of two ways. Either a home inspection turned up a high radon number in the middle of a sale and the clock is ticking, or a homeowner ran one of Idaho's test kits and the result came back over 4.0. Both end the same way: a mitigation system sized to your foundation, installed in about a day, and verified with a clearance test so you're not taking anyone's word for it.
Idaho has a radon disclosure requirement for real estate transactions, and radon testing has become a standard part of Treasure Valley home inspections. A failed test doesn't have to derail your closing. Mitigation can typically be installed within days of the inspection report, with a clearance test 24 to 48 hours after install, fast enough to keep most closings on schedule. Whether you're the buyer negotiating a fix or the seller keeping a deal together, see our real estate radon page for exactly how it works on a deadline.
Very. The Idaho Department of Health and Welfare reports that 2 in 5 tested Idaho homes have radon above the EPA action level of 4.0 pCi/L, and high levels have been found in every county in the state. In some Boise zip codes, 36% of tested homes come back high.
Most existing-home systems in the Treasure Valley run $800 to $2,500 depending on your foundation type. Homes with crawl spaces that need a sealed membrane land toward the higher end. You get a firm quote before any work starts.
Most residential systems go in within a single day. On a real estate deadline, the post-mitigation clearance test typically follows within 24 to 48 hours so your closing stays on schedule.
Yes. A properly installed sub-slab or sub-membrane depressurization system routinely brings homes from well above 4.0 pCi/L to under 2.0, often under 1.0. Every system is verified with a post-mitigation radon test so you see the numbers yourself.
Yes. Radon rises from the soil into your living space through the stack effect, the natural upward movement of air in a house. Idaho homes with crawl spaces are a primary entry path, which is why sealed crawl space membranes are a core part of mitigation here.
Radon is the second leading cause of lung cancer in the United States after smoking, and the leading cause in people who have never smoked. The EPA attributes roughly 21,000 lung cancer deaths a year to it. It's invisible, odorless, and tasteless, so testing is the only way to know your number.
