Frozen pipes cause many Reno losses
In Reno, a large share of water damage starts with cold weather. NOAA's engineering weather data for the Reno airport records an average of about 123 freeze-thaw cycles a year, and Washoe County's residential design criteria use a 17°F winter design temperature. Pipes in exterior walls, crawlspaces, garages and attics can freeze and split, and the leak often appears only when the pipe thaws and water pressure returns, sometimes while the family is away. Know where the main shutoff is, and if you travel in winter, keep the heat on and consider shutting off the main water supply.
If a pipe bursts, close the main valve first, then switch off power to any wet area if you can reach the panel safely. Water from a supply line is clean at first, but it doesn't stay that way once it sits in building materials, so start extraction and drying quickly.
The Truckee River and storm flooding
The Truckee River runs through Reno, and NOAA's California Nevada River Forecast Center tracks it at a gauge in the city. Heavy rain, especially on top of snowpack, can raise rivers and creeks and flood low-lying areas. If you live near the river or a creek, know your flood risk, keep valuables off lower floors, and review whether you have flood insurance, which standard homeowners policies typically don't include. After any flood, treat the water as contaminated, wait until officials say it's safe to return, and have the electrical system inspected before power is restored.
Snowmelt and ice
Snowmelt can find its way into basements, crawlspaces and through roofs where ice dams form at the eaves. Water stains on ceilings near exterior walls in late winter often point to ice dams. Keep gutters and downspouts clear, direct downspouts away from the foundation, and check crawlspaces after big melts.
Drying in a dry climate
Reno's high-desert air is dry much of the year, which can help drying. But dry outdoor air doesn't dry the inside of a wall cavity or the underside of a subfloor on its own, and in winter, opening windows lets cold air chill materials and slow evaporation. Professional drying uses air movers, dehumidifiers and sometimes heat to control conditions inside the house, and moisture readings tell you when the job is actually done. Ask the contractor for the daily logs.
Crawlspaces
Many Reno-area homes have crawlspaces where leaks and snowmelt can go unnoticed. If you smell mustiness or see damp insulation hanging from the subfloor, have the crawlspace inspected. Wet insulation should be removed, the space dried, and the cause of the water fixed.
Before you hire
Ask Reno restoration contractors how they handle frozen pipe losses and crawlspaces, how they'll document the job for your insurer, whether they bill the insurer directly, and whether they also rebuild. Look up the contractor with the Nevada State Contractors Board before you sign.
