Water damage in Boise: what to do now, who to call, what it costs
Water spraying or flooding right now?
- Close the main water valve. In Boise homes it is usually in the garage, a utility room, next to the water heater, or in the crawl space where the line enters. Round handle: clockwise. Lever: a quarter-turn so it crosses the pipe.
- Leak at the street, the meter box or before your valve? Call your water utility. For most of Boise that is Veolia: (208) 362-1300.
- Turn off the water heater (gas to "pilot", electric at the breaker).
- Keep away from water near outlets or the panel; switch off wet circuits only from a dry spot.
- Photograph and video everything before cleanup. Your insurance claim depends on it.
- Get drying started within 24–48 hours. That is the U.S. EPA's guidance to help prevent mold.

Boise's water setup, in plain terms
Boise is Idaho's capital and largest city, with 235,684 residents at the 2020 Census. Unlike most U.S. cities, the city government does not run the drinking water system for most residents: a private, state-regulated utility, Veolia Water Idaho (formerly SUEZ and United Water), supplies most of Boise from dozens of wells. Many neighborhoods also have pressurized irrigation from canal water for lawns, on a separate line that is shut off and should be drained before winter.
Why it matters in an emergency: the number to call depends on your water provider, not the city. It is printed on your water bill.
Boise winters: when pipes actually freeze
Average overnight lows at the Boise airport weather station are 24.5°F in December and 24.9°F in January (1991–2020 NOAA Climate Normals). Research by the University of Illinois Building Research Council found that uninsulated pipes in unheated spaces start to freeze when the outdoor temperature falls to about 20°F. With average lows in the mid-20s, the colder nights of a normal Boise winter cross that line.
The pipes that freeze here: crawl spaces, garages, exterior walls, kitchen and bathroom sinks on outside walls, hose bibs and irrigation lines. Leaks often appear the day it warms up, when the ice thaws and the split opens. Full guide: at what temperature do pipes freeze, and when to drip faucets.
Boise homes by age: different weak spots
- Older homes (for example in the North End, the Bench and around downtown): crawl spaces with exposed pipes, older supply piping, less insulation. A musty smell, a higher water bill or a cold, soft floor can mean a hidden leak.
- Newer homes (much of West and Southeast Boise): failed supply hoses to washers, toilets and ice makers, and water heaters in closets next to finished rooms. Check whether a builder warranty still applies.
What water damage costs in Boise
National cost surveys put most restoration jobs between roughly $1,300 and $6,300. Drying clean water runs about $3–$4 per square foot; sewage cleanup about $7+ per square foot, before rebuild. Full breakdown and a worked example: water damage restoration cost.
Insurance in one minute
Sudden, accidental water damage such as a burst pipe is commonly covered. Slow leaks, outside flooding and sewer backup without an endorsement commonly are not.

Quick answers
Who do I call for a water emergency in Boise?
Most Boise addresses get their water from Veolia Water Idaho, a private utility; its main line is (208) 362-1300. Call it for a leak at the street, in the meter box or before your main shutoff. Some Boise-area homes are on other water systems, so check the name on your water bill. Leaks inside the house after your valve are the homeowner's to repair.
Who fixes a burst pipe in Boise, a plumber or a water damage company?
Usually both. A licensed plumber repairs the pipe. A water damage restoration company extracts the water and dries walls, floors and cabinets with commercial equipment, ideally within 24 to 48 hours to help prevent mold.
How much does water damage restoration cost in Boise?
National cost surveys put most jobs between roughly $1,300 and $6,300, with averages around $1,500 to $3,800 depending on the survey. Clean water caught early is the cheap end; sewage, crawl spaces, hardwood and mold are the expensive end.
Does homeowners insurance cover a burst pipe in Idaho?
Sudden and accidental water damage, such as a burst pipe, is commonly covered. Slow leaks, wear and tear, outside flooding and sewer backup without an endorsement commonly are not. Your policy wording decides.
Are older North End homes more likely to have pipe problems?
Older homes in any neighborhood are more likely to have aging supply pipes, less insulation around plumbing and crawl spaces with exposed pipes. Insulating exposed pipes and knowing where the main shutoff is are the cheapest protections.
