From dirt-crawl-space historic homes near downtown to new builds off the Highway 16 corridor, radon systems matched to Nampa's two housing eras. Same pricing as Ada County, no trip charge.

Dirt crawl spaces are the textbook radon path: open soil, vented straight to the living space. Those homes get a sealed sub-membrane system that fixes the radon number and the damp, musty crawl space in one pass. Basement homes get sub-slab depressurization.
The newer subdivisions, north Nampa off Highway 16's growth corridor, and the builds ringing Lake Lowell, are crawl space construction like the rest of the valley's new stock, with the occasional passive rough-in ready for a fan. And with Nampa's sales volume climbing, radon increasingly shows up mid-transaction here too, that's real estate radon, run on a closing clock.
Both. Idaho DHW has found high radon in every county in the state, and 2 in 5 tested Idaho homes overall come back above the action level. Canyon County's mix of older homes and fast new growth spans every foundation type, which changes the fix, not the risk.
It's the classic setup: open soil under the house, vented to your living space by the stack effect. The fix is a sealed sub-membrane system, and it usually solves the musty-crawl-space problem at the same time.
No. Nampa and Caldwell are core service area, same flat-quote process, same one-day installs, same clearance testing as Ada County.
