Long Island winters and Nor’easters put real stress on plumbing. When water in a pipe freezes, it expands with enough force to split copper or crack a fitting — and the damage often does not show until the pipe thaws and water pours out. If you have a pipe that is frozen but has not burst yet, acting fast can save you the flood.
We thaw frozen lines safely with controlled heat — never an open flame, which is a fire risk and can crack the pipe — and repair burst sections quickly. Just as important, we find out why it froze: an uninsulated run, an exposed line in an unheated space, or a vulnerable spot that will freeze again next winter unless it is addressed.
Signs You Need This Service
- No water or only a trickle from a faucet in cold weather
- Frost visible on an exposed pipe
- A bulge, split, or crack in a pipe
- Water spraying or pooling after a hard freeze
- A section of the house with no water while the rest is fine
- Banging or knocking as a system tries to push through an ice blockage
What Frozen & Burst Pipe Repair With Us Includes
Every frozen & burst pipe repair job is different, but here is what you can expect a Hydrosphere Corp visit to cover:
- Locating the frozen section or the burst point — often in an unheated wall, attic, crawlspace, or garage
- Controlled thawing with safe heat — never an open flame
- Replacement of the split pipe section or failed fitting
- A pressure test of the full run, since ice can hide a second crack
- Identification of the vulnerable run that froze in the first place
- Freeze-prevention options — insulation, rerouting, or heat cable
- Restoration coordination when a burst has already caused water damage
If a pipe freezes but hasn’t burst yet
A frozen pipe that has not yet split is your chance to avoid a flood. Open the affected faucet so melting water can escape and relieve pressure. Keep the area warmer if you can. Do not use a torch or open flame — it is a fire hazard and can crack the pipe from thermal shock. Call us for controlled thawing and a leak inspection, because a pipe that froze once has a weak spot and needs to be checked.
Why the burst often shows up during the thaw
Ice can hold a cracked pipe closed while it is still frozen. As it thaws, the crack opens and water escapes — sometimes far from the freeze point. That is why we inspect the full run after thawing, not just the obvious spot, and why a "it’s flowing again" moment is not always the all-clear. We pressure-test to be sure.
Preventing frozen pipes on Long Island
The pipes that freeze are almost always the exposed ones — in exterior walls, unheated garages, crawlspaces, attics, and along the rim of the basement. Insulating those runs, sealing drafts, keeping heat on during a cold snap, and knowing your shutoff location are the practical defenses. Before winter, we can inspect your vulnerable runs and address them before the first hard freeze.
After the thaw, we inspect the whole run
Ice can hold a cracked pipe closed while it's still frozen, so the leak often appears during the thaw — sometimes far from the original freeze point. That's why 'the water's flowing again' is not the all-clear.
We thaw the line under control, replace the failed section, and then pressure-test the entire run to find any second crack before it becomes tomorrow's flood. Then we address why it froze, so the same exposed run doesn't fail again next winter.
Freezing, heating, and water damage
Frozen pipes and heating failures go hand in hand, so if your boiler has quit in the cold we address both. When a burst has already flooded a finished space, we coordinate water cleanup and keep the plumbing repair separate for your claim.
We answer freeze and burst-pipe emergencies 24/7 across Commack and Northport through the coldest stretches of winter.
Our Process
- 1
Locate the freeze or break
We find the frozen section or the burst point — often in an unheated wall, crawlspace, attic, or exterior wall run.
- 2
Thaw safely
Controlled heat, never an open flame, so the pipe thaws without cracking and without a fire risk.
- 3
Repair the burst
We replace the split section or fitting and pressure-test the repair before restoring full service.
- 4
Prevent the next freeze
We identify the vulnerable run and recommend insulation, rerouting, or protection so it does not happen again.
What Affects the Price
We don’t post flat prices, because an honest number depends on your specific situation. For non-emergency work you’ll always get a written scope before we begin. The main factors:
- Whether the pipe is frozen only or has already burst
- Location and accessibility of the affected run
- Extent of the break and how much pipe must be replaced
- Whether water damage requires restoration coordination
- Preventive work chosen — insulation, rerouting, or heat cable
- After-hours timing during a storm or cold snap
