The short answer
Listen for These Sounds
A frozen pipe can make a few distinct noises. When you turn on a faucet, you might hear a high-pitched whine or whistle, which happens because water squeezes past ice or through a narrowed opening. A gurgling sound can also occur as air bubbles move through the partially blocked pipe.
Banging or clanking sounds are another clue. These can happen when ice shifts inside the pipe or when water pressure causes the pipe to knock against walls or floor joists. If you hear any of these sounds, especially during cold weather, treat it as a warning sign of a possible freeze.
- High-pitched whine when water runs
- Whistling from a restricted flow
- Gurgling as air passes through
- Banging or clanking from shifting ice
- No sound at all when water is fully blocked
- Dripping sound from a nearby leak
Why Pipes Freeze
Pipes freeze when water inside them drops below 32 degrees Fahrenheit. This often happens in unheated areas like attics, crawl spaces, garages, or along exterior walls. Even a small crack or gap in insulation can let cold air reach a pipe and cause ice to form.
As water freezes, it expands, which can put pressure on the pipe walls. That pressure can lead to a burst, even if the ice itself doesn't block the pipe completely. Understanding where your pipes are most vulnerable helps you know what to listen for and when to act.
What to Do If You Hear It
If you suspect a frozen pipe, turn off the water at the main shutoff valve right away. This limits the amount of water that can leak if the pipe bursts. Then open a faucet slightly to relieve pressure, but do not run the water for long if it's not flowing.
You can try to warm the pipe with a hair dryer or a space heater, but never use an open flame. Start near the faucet and work toward the frozen section. If you cannot locate the freeze or the pipe has already burst, contact local water damage pros for help.
- Turn off the main water shutoff valve
- Open a faucet to relieve pressure
- Warm the pipe with a hair dryer
- Never use an open flame or torch
- Check for cracks or leaks after thawing
- Call the pros if the pipe bursts
Preventing Frozen Pipes
Prevention is easier than dealing with a burst pipe. Insulate pipes in unheated areas with foam sleeves or wrap them with heat tape. Seal gaps around windows, doors, and where pipes enter the home to keep cold air out. During a cold snap, let a trickle of water run from faucets to keep water moving.
Keep cabinet doors open under sinks so warm air can reach the pipes. If you plan to be away, set the thermostat to at least 55 degrees Fahrenheit and ask someone to check your home. Knowing where your shutoff valve is located helps you act fast if you hear trouble.
When to Call the Pros
If a pipe bursts, you need professional help to handle water damage. The pros can extract standing water, dry out walls and flooring, and check for hidden moisture. They also help with cleanup after the pipe is repaired, reducing the risk of mold and structural issues.
Even if the pipe doesn't burst, a professional inspection can confirm there are no cracks or weak spots. If you live in Mesa, keep your shutoff valve location written down so you can act quickly. The pros can also help with water damage from a burst pipe, including drywall repair and flooring removal.

Can a frozen pipe burst even if you hear no sound?
Yes, a pipe can freeze and burst without making any sound, especially if the ice completely blocks water flow. If you have no water from a faucet during cold weather, check for visible frost on exposed pipes and listen for dripping or cracking sounds.
How long does it take for a pipe to freeze?
It depends on the temperature, pipe location, and insulation. In extreme cold, a pipe can freeze in a few hours if it's exposed to drafts. Homes with poor insulation or unheated areas are more at risk. Acting quickly when you hear sounds can prevent a burst.
What should a homeowner do if a pipe bursts?
Turn off the main water shutoff valve immediately to stop the flow. Then call the pros to handle the cleanup. They can extract water, dry the area, and help with repairs. Avoid touching standing water if it's near electrical outlets or appliances.
