The short version for everyone on the deal

A high radon number on a Treasure Valley inspection is common, 2 in 5 tested Idaho homes come back over the EPA action level, and it's one of the cheapest, fastest findings to fix. Typical cost: $800 to $2,500. Typical timeline: quote in a day or two, install in one day, clearance test 24 to 48 hours later. Idaho has a radon disclosure requirement for real estate transactions, so handling it properly, with a documented clearance test, protects both sides.

If you're the buyer

Don't walk away from the right house over a radon number. Radon is a property-condition issue like a worn roof or an aging water heater, except it's fixed in a day and verified with hard numbers. Your move: request mitigation as an inspection repair, or take a credit at closing and have the system installed on your own terms. Either way you end up with a documented system and a clearance test showing the post-fix level, which is more than most homes in the valley can show. If the home already has an old system, have it inspected and retested before you trust it, fans age and membranes get damaged.

If you're the seller

A high test isn't a scarlet letter, but under Idaho's disclosure requirement it's now part of your sale. The strongest play is usually to fix it: an $800 to $2,500 system with a passing clearance test converts the finding into a feature. "Radon mitigation system installed, tested at 1.2 pCi/L" reads a lot better in a disclosure than an open question mark, and it removes the one repair negotiation most likely to spook a Treasure Valley buyer's agent.

If you're the agent

You need speed and paper. Speed: one call gets a quote within a day or two, a one-day install, and a clearance test 24 to 48 hours later, so your closing date survives. Paper: a labeled system, the install details, and a documented post-mitigation result you can put in front of both parties and the lender. Radon findings kill deals when they sit unresolved for two weeks of finger-pointing. Handled inside 72 hours, they're a line item.

Common questions

The inspection found high radon. Is the deal dead?

No. A high radon result is one of the most fixable findings on an inspection report. Mitigation typically installs within days, a clearance test follows in 24 to 48 hours, and most closings proceed on their original schedule. It's a repair negotiation, not a deal-breaker.

Who pays, buyer or seller?

Negotiable, like any inspection repair. Commonly the seller installs or credits the cost at closing, since a mitigated home with a documented clearance test is easier to sell. Buyers sometimes take a credit and handle it after closing. Either way, $800 to $2,500 is small next to the transaction.

We close in two weeks. Is that enough time?

Comfortably. Quote within a day or two, one-day install, clearance test 24 to 48 hours after. Even tighter closings are usually workable.

Does Idaho require radon disclosure?

Yes, Idaho has a radon disclosure requirement for real estate transactions. A documented mitigation system with a passing clearance test turns radon from a disclosure liability into a selling point.

The house already has a system. Are we good?

Not automatically. Fans age, membranes get damaged, and old systems can underperform. A quick inspection plus a current test confirms it's actually holding levels down before you close on it.
