Frozen pipes are a homeowner’s nightmare. Like any plumbing emergency, it usually happens without warning and never at a convenient time. If you think your pipes are frozen it’s important to act fast so things don’t get worse—and more expensive—with a burst pipe. Here’s what you can do if you suspect your pipes are frozen.
How to Identify Frozen Pipes
Are your pipes frozen? Or is there another plumbing issue to handle. To confirm that your water pipes are frozen look for these signs:
- No water or slow water flow: You turn on the faucet and only a trickle (or no water) comes out.
- Frost on pipes: If you can check any exposed pipes located in unheated areas like a crawl space or exterior wall, check them for visible frost.
- Strange smells: When a pipe is blocked by ice, you can experience unusual odors from faucets or drains.
What To Do If Pipes Are Frozen
If you notice any of these signs, take these precautions to avoid a bigger problem with a burst pipe.
1. Shut Off the Water Supply
Find your home’s main water valve and turn it off. This will reduce the pressure in the pipes, lowering the risk of a pipe burst when the ice thaws.
2. Check for Leaks or Damage
Check the frozen pipe and surrounding areas for cracks, dripping water or sections that are bulging. If you notice any damage, keep the water off and contact a plumber immediately.
3. Open Faucets
Turn on the faucet that’s showing the signs of a frozen pipe but only slightly. The running water will help melt the ice inside the pipe and relieve the built-up pressure.
Thawing Frozen Pipes Safely
Next, try these safe thawing methods:
Hot Air from a Hair Dryer or Heat Lamp
- Direct the warm air toward the frozen section of the pipe.
- Move the heat source along the pipe slowly—do not concentrate on one spot for too long.
- Avoid using an open flame. This creates a fire hazard and can cause additional damage to the pipes.
Heat the Area with a Space Heater
- If the pipes are located in an unheated area of your home and it can safely fit, place a space heater in the room to gently warm the pipes.
- Always keep the space heater at a safe distance from flammable materials.
Wrap the Pipes in Warm Towels
- Soak towels in warm (not boiling) water and wrap them around the frozen section of pipe.
- Repeat with fresh, warm towels as needed until the ice thaws.
If the frozen pipe is located inside a wall, turn up your home’s thermostat or direct warm air to the affected area using a fan.
Avoid DIY Disasters
Some DIY pipe thaw methods can do more harm than good. Avoid these frozen pipe don’ts:
- Do not use an open flame or torch: This can damage the pipes and, even worse, cause a fire.
- Do not pour boiling water on pipes: Sudden temperature changes can cause pipes to crack.
- Do not use chemical de-icers: They can corrode pipes and make your water unsafe for drinking.
When to Call the Pros
If you’ve tried thawing your frozen pipes and are still having trouble getting normal water flow or if you notice any of these warning signs, it’s time to call a plumber:
- A pipe burst or visible leaks.
- The frozen section of pipe is inaccessible inside a wall or under the floor.
- Pipes remain frozen even after trying to thaw them.
- Multiple pipes are affected, which could mean a more significant plumbing issue.
Your homeowners insurance will likely cover water damage resulting from burst pipes but you don’t want the situation to escalate to that point. Home warranties, on the other hand, generally do not cover water damage from burst or frozen pipes.
