Winter brings cozy fires and hot cocoa — but it also brings the risk of frozen pipes. When water freezes inside your pipes, it expands with tremendous force. That expansion can burst pipes, flooding your home and causing thousands of dollars in damage.
The key is acting before a burst happens. Knowing the signs of frozen pipes can save you a massive headache.
7 Signs Your Pipes Are Frozen
Watch for these warning signs:
- No water flow — turn on a faucet and nothing comes out. That’s the most obvious sign.
- Slow or reduced water flow — water barely trickles out instead of flowing normally.
- Frost on visible pipes — if you can see exposed pipes, frost on the outside is a clear warning.
- Unusual smells — a strange, musty odor coming from faucets (because water can’t flow to push out debris).
- Clanking or bulging pipes — sounds of expansion or a visibly bulging pipe.
- Cold temperatures in walls — walls feeling unusually cold near pipes.
- High water bill — a hidden leak from a partially frozen pipe can spike usage.
- Outdoor faucets (hose bibs)
- Pipes in unheated spaces — basements, attics, garages, crawl spaces
- Pipes along exterior walls — especially those with little insulation
- Sprinkler lines
- Use a hair dryer — start at the faucet end and work backward.
- Apply heat tape — wrap specially designed heat tape around the pipe.
- Use a space heater — place it safely near the frozen section (keep it away from flammables!).
- Wrap pipes in heating cable — available at hardware stores.
- Insulate exposed pipes — use foam pipe insulation (cheap and easy).
- Disconnect outdoor hoses — and shut off outdoor water supplies.
- Let faucets drip — a tiny trickle keeps water moving, preventing freezing.
- Open cabinet doors — warm air can reach pipes under sinks on exterior walls.
- Seal air leaks — caulk gaps near pipes in walls and foundations.
- Keep garage doors closed — if water lines run through the garage.
- You can’t locate the frozen section
- The pipe has burst or is leaking
- Frozen pipes are behind walls (can’t access them)
- Multiple pipes are frozen throughout the house
Which Pipes Are Most at Risk?
Some pipes are more exposed than others:
If your pipes are in these areas, it’s worth taking preventive measures before temperatures drop.
What to Do If Your Pipes Are Frozen
Step 1: Turn off the water supply
Locate your main water shutoff valve and turn it off. This minimizes flooding risk if the pipe bursts.
Step 2: Thaw the pipe safely
You can thaw a frozen pipe yourself — just do it carefully:
Important: Never use an open flame (torch, propane heater) — fire hazard!
Step 3: Check for leaks
Once thawed, turn the water back on slowly and watch for any leaks. If you see water spraying or pooling, you’ve got a burst pipe — call a plumber immediately.
