Water expands as it freezes. When water inside a pipe freezes, the ice pushes against the water trapped between the ice and a closed faucet, raising pressure until the pipe bursts. Often the break occurs not where the ice formed but in a section where pressure built up. When the ice melts, water pours out through the break.
Our technicians respond to frozen and burst pipe calls across Afton, MN 24 hours a day, thawing lines safely, repairing damaged sections and recommending steps to prevent future freezes.
Where and why pipes freeze
Pipes most vulnerable to freezing run through unheated spaces such as crawl spaces, garages, attics and basements, or along exterior walls with little insulation. Outdoor hose bibs and irrigation lines are also at risk. Pipes near foundation vents, cracks or openings where cold air enters are especially susceptible.
Freezing depends on temperature, duration and wind. A brief dip below freezing may not freeze pipes, while extended periods of severe cold can freeze even pipes in partially heated areas. Wind increases heat loss from exposed surfaces.
Homes left unoccupied with the heat turned down, or buildings with heating failures during cold weather, face high risk. Kitchen and bathroom pipes inside cabinets on exterior walls are common trouble spots because the cabinet doors keep warm room air away from the pipes.
Plastic pipes such as PEX tolerate some freezing better than copper, but they can still split, and fittings can fail. No pipe material is immune.
What to do if you suspect a frozen pipe
Signs of a frozen pipe include a faucet that delivers little or no water in cold weather, frost on visible pipes and unusual odors from drains. If you suspect a frozen pipe, keep the faucet open so water can flow as the ice melts, which relieves pressure.
Apply gentle heat to the frozen section using a hair dryer, heating pad or space heater kept at a safe distance. Never use an open flame, propane torch or other high heat source, which can cause fires or damage pipes. Start warming from the faucet end and work toward the frozen area so melting water can escape.
Check other faucets for flow. If one pipe froze, others may have too. If you cannot locate or reach the frozen section, or if thawing does not restore flow, call for professional help.
If a pipe has burst, shut off the main water valve immediately and call for repair. Turn off electricity to areas where water is leaking near outlets or appliances if it is safe to do so.
How we thaw and repair pipes
Our technicians locate frozen sections using visible frost, temperature readings and knowledge of typical pipe routes. We thaw pipes using safe methods such as controlled heat, warm air and electric pipe thawing equipment where appropriate for the pipe material.
Once water is flowing, we inspect the line for leaks. Burst sections are cut out and replaced using materials suited to the existing plumbing. Joints are soldered, crimped or connected with approved fittings and pressure tested.
Where water has leaked, we identify areas that may need drying or further attention. Significant water damage may require restoration specialists, and we can explain what to look for.
After repair, we discuss why the pipe froze and recommend steps to prevent recurrence, such as insulation, sealing air leaks, heat cable or rerouting vulnerable lines.
Preventing frozen pipes
Insulate pipes in unheated areas with foam pipe insulation, paying attention to fittings and valves. Seal gaps and cracks where cold air enters crawl spaces, basements and garages.
During cold snaps, open cabinet doors beneath sinks on exterior walls to let warm air reach the pipes, and let faucets drip slightly to keep water moving. Keep the heat set at a safe level even when away.
Disconnect garden hoses and shut off and drain outdoor faucets before winter, or install frost-proof hose bibs. Drain irrigation systems according to the manufacturer's instructions.
For pipes that cannot be protected by insulation alone, thermostatically controlled heat cable can provide warmth. For homes left vacant in winter, consider shutting off the water and draining lines, or using a low temperature alarm that alerts you if indoor temperature falls.
Water damage, insurance and what to do after a burst
The first priority after a pipe bursts is stopping the water. Once the main is off and electricity is shut off to affected areas, take photographs of the damage before moving anything, since insurance companies usually want documentation. Remove valuables and electronics from wet areas and begin removing standing water with towels, mops or a wet vacuum if it is safe to do so.
Drying quickly limits damage. Water that soaks into drywall, insulation, subflooring and cabinetry can lead to warping, staining and mold growth if it is not dried within a day or two. For anything beyond a small, contained leak, a water damage restoration company with dehumidifiers and air movers can dry the structure properly and measure moisture content to confirm it is dry.
Homeowners insurance policies differ in how they treat burst pipes, especially if the home was vacant or the heat was turned off. Contact your insurer promptly to report the damage and understand your coverage. We provide invoices and descriptions of the repair that you can share with your insurer.
After the repair and drying are complete, consider whether the conditions that caused the freeze have been addressed. A pipe that froze once in a particular spot will likely freeze again under similar conditions unless insulation, air sealing, heat cable or rerouting changes the situation.
Signs your pipes may be frozen or damaged

Bulging or cracked pipe
Ice expansion can deform or split pipes.
Water stains or dripping
A burst pipe may be leaking inside walls or ceilings.
Unusual sounds when using water
Banging or whistling may indicate ice or damage.

Common questions about frozen pipe repair
Can I thaw a frozen pipe myself?
If you can reach the frozen section, open the faucet it feeds and apply gentle heat with a hair dryer, heating pad or warm towels, starting near the faucet and working back toward the frozen area. Never use a torch or open flame, and keep electrical devices away from water. If you cannot find the frozen section, or water does not start flowing, call for help before the pipe splits.
Why did my pipe burst after it thawed?
The pipe usually split while it was frozen, as expanding ice raised the pressure in the trapped section of water. While frozen, the ice plugs the break, so there is no leak. When it thaws, water flows again and escapes through the split, which is why leaks often appear hours after a cold night ends.
Should I leave faucets dripping in cold weather?
On very cold nights, letting faucets on exterior walls drip slowly keeps water moving and relieves pressure in the line, which lowers the risk of a burst. Drip both hot and cold on single handle faucets. Combined with open cabinet doors under sinks, this simple step prevents many freeze calls.
What temperature causes pipes to freeze?
Pipes in unheated or poorly insulated spaces are at risk whenever the surrounding air stays below freezing for several hours. Wind, drafts through gaps in the foundation and how long the cold lasts all affect the risk. Pipes in heated spaces rarely freeze unless the heat fails or they run along a very cold exterior wall.
Are PEX pipes freeze-proof?
No. PEX tubing can stretch somewhat as water freezes, which gives it more tolerance than copper, but it can still split, and brass or plastic fittings can crack. Pipes of any material in vulnerable locations still need insulation, air sealing and, where necessary, heat cable.
