Massachusetts officials warned in January 2026 that cold weather significantly raises the risk of frozen and burst pipes across the state. In a hill town, the first sign is often a ceiling stain that appears once the weather turns.
Where a frozen pipe leaks
Ice blocks the pipe and pressure builds behind it until the pipe wall splits. The water stays contained while it is frozen, so the leak starts at the thaw, often inside an exterior wall, above a ceiling or in a cold corner. The crew traces the wet path with meters before cutting anything.
- Exterior wall cavities where insulation is thin.
- Pipes running above porches and garages.
- Cold corners near sills and rim joists.
- Cabinets under sinks that sit on outside walls.
