Why winter is the risky season here
At the Boise airport weather station, average overnight lows sit near or below freezing from November through February (November 32.3°F, December 24.5°F, January 24.9°F, February 29.3°F; 1991–2020 NOAA Climate Normals). That means pipes in crawl spaces, garages, exterior walls and unheated rooms can freeze, and they often split when they thaw.

First steps for any water emergency
- Close the main water valve and, for a burst supply line, turn off the water heater (gas: set to "pilot"; electric: switch off its breaker).
- Make it safe: keep away from water near electrical outlets or the panel.
- Document everything with photos before cleanup.
- Move valuables, rugs and electronics out of wet areas and onto a dry floor.
- Get professional drying started. Ask any company you call whether it is registered with the Idaho Contractors Board and insured, whether it bills your insurer directly, and when a technician can arrive.
Which Treasure Valley homes are most at risk
The Treasure Valley grew fast: Meridian and Nampa alone added tens of thousands of residents since the 2020 Census, according to regional planning agency COMPASS. That leaves a mix of older and newer homes, and they fail in different ways.
Older homes (much of Boise's North End and Bench, older Nampa and Caldwell)
- Crawl spaces with exposed pipes that freeze on cold nights and can leak for days unnoticed.
- Aging supply pipes, including galvanized steel in some houses, that corrode from the inside.
- Less insulation around pipes in exterior walls and under sinks on outside walls.
Newer homes (much of Meridian, Kuna, Star and West Boise)
- Supply hoses and push-fit fittings to washers, toilets and ice makers that fail at full pressure.
- Water heaters and washers in closets or upstairs, next to finished rooms and ceilings.
- Pressurized irrigation lines that must be shut off and blown out before winter.
