During New Hampshire’s coldest months, frozen pipes are one of the most common—and costly—winter plumbing problems. When water inside your pipes freezes, it expands, creating pressure that can lead to cracks, leaks, or even a full pipe burst. Knowing the early warning signs can help you act quickly and prevent serious damage.

Signs Your Pipes May Be Frozen

1. Little or No Water Coming from a Faucet
If you turn on a faucet and only a trickle comes out—or nothing at all—a portion of the supply line may be frozen.

2. Frost on the Outside of the Pipe
Visible frost is a clear indicator that the pipe is cold enough internally for freezing to occur.

3. Unusual Sounds When the Water Runs
Banging, clanking, or gurgling noises can indicate that ice is restricting water flow.

4. Strange Smells from Sinks or Drains
If a pipe is frozen and blocked, odors may travel back up through your drains.

5. Pipes Feel Extremely Cold to the Touch
Exposed pipes in basements, crawl spaces, or garages often freeze first. If they feel colder than normal, they may be at risk.

What to Do If You Think Your Pipes Are Frozen

1. Turn Off the Water Supply
Shut off the main water valve to reduce pressure and prevent a burst pipe.

2. Gently Warm the Pipe
Use a hair dryer, space heater, or warm towels. Never use an open flame or propane torch.

3. Open Faucets
Allow water to trickle through. Moving water helps melt ice faster.

4. Check for Leaks as the Pipe Thaws
If you notice dripping or water pooling, you may already have a burst or cracked pipe.
