The short answer
What Freezing Does to Pipes
Water expands by about 9 percent when it freezes. That extra pressure can split metal or plastic pipes, especially at joints and bends. Even a small crack can leak gallons of water once the ice melts, soaking floors, walls, and ceilings.
The boiler itself may also suffer if the water inside freezes. The heat exchanger or pump can crack, leading to more extensive repairs. You might not notice the damage until temperatures rise and the ice turns back to water, so check your boiler room regularly during cold snaps.
Signs Your Pipes May Be Frozen
Look for visible frost on exposed pipes, a lack of hot water, or strange gurgling sounds when you turn on a tap. If the boiler pressure drops suddenly, that can indicate a leak from a frozen pipe. Pay attention to any damp spots on walls or ceilings near the boiler.
Freezing weather can happen in many areas, even those with mild winters. Keep your thermostat at a consistent temperature and open cabinet doors to let warm air reach pipes. Knowing where your main shutoff valve is can save precious time.
- Check for frost or ice on exposed pipes
- Listen for unusual noises from the boiler
- Notice any sudden drop in boiler pressure
- Look for damp spots on walls or floors
- Feel for cold spots near pipe runs
- Monitor your water bill for unexpected increases
Immediate Steps to Take
If you suspect a frozen pipe, shut off the main water supply right away. This stops more water from entering the system and reduces the risk of flooding. Then open a faucet to relieve pressure in the pipes, which can help prevent bursting.
Do not use a blowtorch or open flame to thaw pipes, as that can damage them or start a fire. Instead, use a hair dryer or warm towels on the affected area. If you notice any leaks or water damage, turn off the boiler and contact the pros for help.
How the Pros Handle the Damage
When you call the pros, they will first assess the extent of the water damage. They may use moisture mapping to find hidden moisture in walls and floors. Then they can extract standing water and set up drying equipment to prevent mold growth.
The work usually involves removing damaged drywall or flooring, drying the structure, and repairing the pipes. The pros will also check for any electrical hazards before starting. They can guide you through the process and help you understand what needs to be replaced versus what can be saved.
- Extract standing water from affected areas
- Set up dehumidifiers and air movers
- Locate and repair the cracked pipe
- Dry out walls, floors, and ceilings
- Replace water-damaged drywall or insulation
- Check for mold and treat as needed
Preventing Future Freeze Damage
Insulate exposed pipes in unheated areas like attics, crawl spaces, or garages. Use foam pipe insulation or heat tape, and seal any gaps where cold air can reach the pipes. Keep your thermostat set to at least 55 degrees Fahrenheit, even when away.
During a hard freeze warning, let faucets drip slightly to keep water moving. Open cabinet doors under sinks to let warm air circulate. If you have a boiler, follow the manufacturer's recommendations for winterizing. A little preparation can save you from a major cleanup later.
Water damage does not wait
Water keeps spreading into floors and walls, so it is worth acting early. Calls are answered 24/7.

How long does it take for pipes to freeze?
It depends on the outdoor temperature, pipe insulation, and water flow. In general, pipes can freeze within a few hours when temperatures drop below 20 degrees Fahrenheit. Uninsulated pipes in unheated areas freeze faster. Keep an eye on the weather and take precautions early.
Can I thaw frozen pipes myself?
Yes, you can try gentle methods like using a hair dryer or warm towels. Never use open flames or blowtorches. If you can't reach the pipe or if it has already burst, shut off the water and call the pros. They have the right tools and experience to handle the situation safely.
Will my insurance cover frozen pipe damage?
Policies vary, and your insurer decides what is covered. Many homeowner policies cover water damage from burst pipes, but some exclude damage caused by neglect or lack of heat. Check your policy and document all damage with photos. Contact your insurance company to file a claim if you have one.
