Frozen Pipe Thawing & Repair
Frozen pipes happen when water inside a supply line turns to ice, usually in exterior walls, attics, or crawl spaces during extreme cold. The ice can block flow completely and the pressure behind it can burst the pipe. FlowFast connects you with an independent local plumber who can thaw the line safely, check for cracks, and repair any burst sections.

Emergency PlumbingBurst pipe or major leak right now? What counts as a plumbing emergency, what to do before the pro arrives, and how to get connected with an independent local plumber fast.
View all Emergency servicesThe first sign of a frozen pipe is usually a faucet that gives only a trickle — or nothing at all — on a bitterly cold morning. The freeze itself is only half the danger: as ice expands it can split the pipe, and the real flooding often starts when the ice thaws and water rushes through the crack. That is why a frozen pipe is an emergency even before it bursts. Pipes in exterior walls, unheated garages, attics, and crawl spaces are the most vulnerable, especially if they were never insulated.
FlowFast connects you with an independent local plumber who can locate the frozen section and thaw it gradually using controlled heat, which is far safer than a homeowner blasting the spot with a torch. The pro will inspect the thawed line for splits and leaks, repair any damage, and advise on insulation, heat tape, or rerouting that keeps the same pipes from freezing again. Catching a freeze early is the difference between a thawing visit and a flooding repair. Fast professional help is what turns a potential disaster into a manageable repair.
Warning signs
Signs you need this service
- A faucet that produces only a trickle or no water at all while other faucets in the house work normally.
- Frost or condensation visible on an exposed pipe, or a pipe that feels extremely cold to the touch. And do not ignore it.
- Strange clanking, banging, or whistling sounds in the walls when a faucet is turned on during a cold snap. And prompt attention prevents costlier damage.
- A sudden water stain or damp spot appearing as temperatures rise, which can mean a frozen pipe has thawed and cracked.
What to expect
The process, step by step
The pro locates the frozen section, often by tracing which fixtures are affected and inspecting vulnerable runs. Keeping you informed at every stage.
The pipe is thawed gradually with controlled heat, starting from the faucet end so melting water can escape. Ensuring the problem is fully resolved.
Once thawed, the line is inspected for splits or leaks, and any burst sections are cut out and replaced. Keeping you informed at every stage.
They recommend freeze protection for the area, such as insulation or heat tape, to prevent a repeat. Which keeps the work neat and contained.
Prevention
How to avoid this problem
- Insulate pipes in unheated areas and seal gaps where cold air reaches them, especially on exterior walls. So stay consistent.
- During extreme cold, let vulnerable faucets drip and open cabinet doors so warm air reaches pipes under sinks.
- Keep the thermostat at a steady temperature day and night, and never shut heat off completely when traveling in winter.
