How to Keep Frozen Pipes From Bursting in Reno, NV

Reno's high-desert winters can send overnight temperatures well below freezing, and that's exactly when pipes are most likely to freeze, swell, and burst. A burst pipe can release 10 to 12 gallons of water a minute, and few things wreck a Reno home's floors, walls, and belongings faster. The good news: a few preventative steps can save you thousands of dollars in repairs. For over 47 years, Easy Rooter Plumbing — trusted plumbers in Reno (links to homepage) — has helped local homeowners winterize their homes and recover fast when pipes do freeze.

Why Do Pipes Freeze and Burst in Reno Winters?

When temperatures drop, water inside a pipe can freeze and expand. That expansion builds pressure between the ice blockage and a closed faucet until the pipe wall gives way — often at a joint or fitting, not necessarily where the ice formed. Pipes running through unheated spaces (garages, crawl spaces, attics, and exterior walls) are the most exposed, and Reno's freeze-thaw swings between sunny afternoons and single-digit nights make these areas especially vulnerable.

10 Tips to Prevent Frozen Pipes

1. Insulate exposed pipes before winter sets in.
2. Seal drafty windows and doors, and insulate attics, basements, and crawl spaces.
3. Run warm water through the pipes periodically to keep water moving and prevent freezing.
4. Open cabinet and vanity doors so warm room air can reach the pipes underneath.
5. Use a small space heater or fan to circulate heat into consistently cold rooms.
6. Keep the garage door closed to keep cold air away from pipes running along garage walls.
7. Let faucets drip slightly during a hard freeze to relieve pressure and keep water moving.
8. Leave the heat on — at 55°F or higher — any time you travel during winter.
9. Set your thermostat to the same temperature day and night instead of lowering it overnight.
10. Disconnect garden hoses and drain outdoor spigots before the first freeze.

Not sure which of your pipes are most at risk? A licensed Reno plumbing contractor (links to /service/) can walk your home and flag the spots most likely to freeze — usually faster than waiting for a pipe to fail.

What to Do If Your Pipes Freeze

11. Turn on the faucet the frozen pipe feeds, then apply gentle heat with a hair dryer, working from the faucet end toward the blockage. Thaw slowly and never aim direct heat at a joint.
12. Wrap the pipe in an electric heating pad, or point a portable space heater at it — keeping it at least 3 feet from anything flammable.
13. Never use a blowtorch, propane heater, or other open flame on a pipe. It's a fire hazard and can damage the pipe further.
14. Check nearby pipes and fixtures — if one pipe froze, others exposed to the same cold are likely at risk too.
15. If a pipe has already burst, shut off your main water valve immediately to limit water damage. Locate your main shut-off (links to /shut-off-water-supply-to-your-home/) now, before an emergency, so you're not searching for it in a panic.
16. If exposed pipes keep freezing every winter, consider relocating them or protecting them permanently with heat tape, a pipe sleeve, or a heat cable.
17. Call a licensed emergency plumber in Reno — a professional can safely thaw the pipe and check for hidden cracks before you turn the water back on at full pressure.

Install Smart Technology to Catch Problems Early

A little technology goes a long way toward catching frozen-pipe damage before it starts:

• Temperature sensors that alert your phone when a room approaches freezing.
• Smart thermostats that let you monitor and adjust the temperature remotely while you're away.
• Water leak detection systems that shut off your main water supply automatically if they sense a leak or sudden pressure drop.

Frequently Asked Questions

How cold does it need to get for pipes to freeze?

Pipes are generally at risk once temperatures drop to around 20°F or below, especially in unheated or poorly insulated areas. Reno regularly sees overnight lows in that range during winter, which is why exposed pipes need extra protection here.

How long does it take for a frozen pipe to burst?

It depends on the pipe's exposure and how long the cold lasts, but a hard, sustained freeze can cause a pipe to burst in as little as six to eight hours. That's why fast action — and prevention beforehand — matters.

Can I thaw a frozen pipe myself?

Yes, for pipes you can safely reach — using a hair dryer, heating pad, or space heater as described above. Avoid open flames, and call a professional if you can't reach the pipe, don't see improvement quickly, or suspect it has already cracked.

Does homeowners insurance cover frozen pipe damage?

Most homeowners policies cover sudden water damage from a burst pipe, but coverage details and exclusions vary by insurer. Read our full breakdown in “Does Homeowners Insurance Cover Frozen Pipes?” (links to /does-homeowners-insurance-cover-frozen-pipes/) before you file a claim.

What's the first thing I should do if a pipe bursts?

Shut off your main water valve right away, then call a licensed plumber. Stopping the water flow first is the single most effective way to limit damage while you wait for help.
