When a Pennsylvania cold snap drops into the teens, the pipes in uninsulated basements, rim joists, crawl spaces, and exterior walls are the first to freeze. A frozen pipe is dangerous not because of the ice, but because of the pressure that builds behind it — that is what splits the pipe, often the moment it thaws. Our 24/7 winter crews in King of Prussia thaw frozen lines safely and catch splits before they flood your home.
Never thaw a pipe with an open flame — it is a fire risk and can burst the pipe from thermal shock. We use controlled, safe heat, verify the line as it thaws, and then address the real problem: the exposure that let it freeze in the first place. Because if we do not fix that, it freezes again next week.
Signs of a Frozen or At-Risk Pipe
During a freeze, watch for:
- No water, or a faucet that only trickles, in cold weather
- Frost or bulging visible on an exposed pipe
- A section of pipe that is far colder than the rest
- Whistling or banging when you open a fixture
- Uninsulated pipes in the basement rim joist, garage, or crawl space
- Water damage appearing after a thaw (a sign of a split)
What Our Frozen Pipe Service Includes
We restore flow safely and fix the exposure that let the pipe freeze in the first place:
- Location of the frozen section and a check for splits before any heat
- Controlled, even thawing — never an open flame — with a fixture open to relieve pressure
- A pressure check as flow returns to catch hairline splits from the freeze
- Same-visit cut-out and replacement of any split section
- Pipe insulation and rim-joist sealing on the vulnerable run
- Heat-cable installation in spots that freeze every cold snap
- Rerouting of a run that keeps freezing where insulation is not enough
- Drying coordination if the pipe has already burst

Thaw with controlled heat
Safe, even warming — never an open flame — while a fixture is open to relieve pressure as the ice releases.

We cut out and replace damaged sections the same visit so you are not left with a slow leak.
- 5
Prevent recurrence
Insulation, heat cable, or rerouting the vulnerable run so the same pipe does not freeze again.

Frequently Asked Questions
You can try gentle warmth — a hair dryer, warm towels, and opening the faucet to relieve pressure — on an accessible pipe. Never use an open flame. If you cannot reach the pipe, cannot restore flow, or see any split, call us before the thaw turns into a burst.
A pipe can split while frozen and only leak once it thaws and pressure returns. If you had a freeze followed by water stains, dripping, or a pressure drop, treat it as a burst: shut the main and call. We pressure-test thawed lines to catch this.
Insulate exposed pipes and the rim joist, seal drafts near vulnerable runs, add heat cable in problem spots, keep the heat on in unused rooms, and let a faucet drip during extreme cold. Where a pipe repeatedly freezes, rerouting it is the permanent fix.
Trouble usually starts when temperatures hold in the low 20s or below, especially with wind on an exposed wall. In our climate, uninsulated basements, rim joists, garages, and crawl spaces freeze first. When a hard freeze is forecast, let a faucet drip and open cabinet doors on exterior walls.
Not always, if you thawed it safely and it flows normally with no drips. But a pipe that froze once will freeze again unless the exposure is fixed. If it keeps happening, it is worth having us insulate, add heat cable, or reroute the run so you are not gambling every cold snap.
