Why does a dry desert city still get water damage?
Because the water comes from inside the house and from managed sources, not from constant rain. Plumbing failures, freeze-split pipes, irrigation canals and spring runoff on the Boise River account for most of the local damage, while August is the driest month of the year.
Climate summaries based on NOAA normals put the valley near 12 inches of precipitation a year, with December and January the wettest months at roughly an inch and a half to an inch and three quarters each. Station figures vary, and we quote the range rather than a single number. What matters is the pattern: the wet months are also the coldest, so the main hazard is a freeze followed by a thaw.
The calendar below is a tendency, not a forecast. A mild winter and a heavy runoff spring can fall in the same few years.
What tends to go wrong in the Treasure Valley through the year| Months | What usually goes wrong | Worth doing now |
|---|
| Dec to Feb | Hard freezes split pipes in outside walls, garages and crawl spaces; roofs carry snow | Insulate exposed pipes, know your main shut-off, keep heat on when you travel |
|---|
| Mar to May | Thaw reveals freeze leaks; snowmelt and river runoff raise the Boise River; canals begin to fill | Look at ceilings and walls for stains, check window wells and crawl spaces |
|---|
| Jun to Sep | Irrigation season: yards, laterals and crawl spaces get wet; water heaters and hoses fail in heat | Check hoses on washers and dishwashers, watch the yard grade near the foundation |
|---|
| Oct to Nov | First freezes arrive before pipes are prepared; outdoor hoses left connected split | Disconnect hoses, drain irrigation lines, insulate crawl-space plumbing |

What should you do in the first hour?
Close the valve or main if a pipe is the source, stay out of rooms where water has reached outlets or the panel, photograph everything before moving it, and lift belongings off wet floors. Then call. The EPA advises drying water-damaged materials within 24 to 48 hours to prevent mold.
The main shut-off is the part most people wish they had located earlier. In many houses it is where the line enters the garage, basement or crawl space, and in older homes it can be stiff. Test it once on a dry day so it turns when you need it.
Do not pull up wet carpet or cut drywall before a meter has read it, and never run a household vacuum on sewage or flood water. A photograph, a short list of what was wet and a phone call are worth more than any cleanup you attempt alone.
- Close the supply valve or the main
- Stay out of wet rooms if water has reached outlets, the panel or the furnace
- Photograph and video the damage and the source
- Move electronics, papers and small furniture to dry ground
Who fixes what after the water is out?
The restoration crew removes water and dries the structure. A licensed plumber repairs pipes and water heaters, a roofer repairs the roof, and a drainage or landscape contractor handles groundwater and grading. Hiring them in the right order avoids drying a house that is still leaking.
Idaho registers contractors rather than licensing them, under the Idaho Contractor Registration Act, Idaho Code Title 54, Chapter 52, which the Idaho Contractors Board within the Division of Occupational and Professional Licenses enforces. The agency's FAQ says registration is required for construction work over $2,000 in materials and labor unless an exemption applies, and licensed trades working within their licence, employees and owners working on their own property are exempt.
We could not confirm whether water extraction, drying or mold work on its own counts as construction for registration purposes, so we do not claim an answer. The practical step is to ask any company whether it is registered with the Idaho Contractors Board and to check the lookup on the Division's website yourself before you sign. The contractor guide walks through the questions.
What does water damage restoration cost in Boise?
We print no dollar figure, because we found no local price we could source. A quote follows the wet area, the water category, the materials and the drying days. Ask for the scope, the equipment and the price in writing before work starts, and for rebuilding to be quoted separately.
Two basements with the same depth of water can be very different jobs, which is why a number given over the phone without a look is a guess. The cost guide explains each factor, and the pricing page lists what to ask.
