Frozen pipes occur when water inside a pipe freezes and expands, blocking flow and creating immense pressure. Massachusetts winters regularly bring temperatures below 20 degrees F, and pipes in exterior walls, crawl spaces, and unheated areas are most vulnerable.
A frozen pipe is a burst pipe waiting to happen. As ice expands, it can generate pressure exceeding 2,000 PSI inside the pipe - far more than any residential pipe can withstand. The burst often happens when the pipe thaws and the ice plug releases.
Damage Risk
If the pipe bursts when it thaws, you face all the damage risks of a burst pipe - flooding, structural damage, mold, and ruined belongings. Improperly thawing pipes can also cause them to burst during the thawing process.
Open the faucet served by the frozen pipe. As ice melts, water needs somewhere to go. Running water also helps melt the ice.
Use a hair dryer, heating pad, or warm towels on the frozen section. NEVER use an open flame, propane torch, or heat gun - this can cause the pipe to burst or start a fire.
Be ready to shut off the main water supply immediately if the pipe bursts as it thaws. Know where the valve is before you start thawing.
If one pipe is frozen, others may be too. Check all faucets in the house, especially on exterior walls and in unheated areas.
Once a licensed plumber arrives at your Massachusetts home, here is what the repair process typically looks like:
The plumber locates the frozen section using thermal imaging or by feel along the pipe run.
Professional thawing equipment is used to safely and gradually melt the ice without stressing the pipe.
The pipe is inspected for cracks, bulging, or splits that may have occurred from the expansion.
Any damaged sections are repaired or replaced before water is restored to full pressure.
The plumber advises on insulation, heat tape, or rerouting to prevent future freezing in the same location.
