Quick Answer
Frozen pipes are most likely in unheated areas, exterior walls, crawl spaces, garages, basements, and poorly insulated lines. Prevent winter plumbing damage by insulating vulnerable pipes, sealing drafts, keeping heat on, opening cabinet doors during cold snaps, and knowing how to shut off water fast.
Cold weather exposes weak points fast
Winter does not politely ask whether your plumbing is ready. It finds every draft, uninsulated pipe, exterior-wall line, garage run, crawl space, and basement weak spot. When water freezes, it expands and can split piping or fittings. The pipe may not leak until it thaws, which is a charming little trap nature designed for homeowners. Long Island homes near the coast, older neighborhoods, and properties with additions or unfinished spaces can all have vulnerable plumbing that deserves attention before deep cold hits.
Where frozen pipes usually happen
Frozen pipes often happen in unheated basements, crawl spaces, garages, exterior walls, attics, laundry areas, hose bib lines, and under kitchen or bathroom cabinets on outside walls. Pipes near air leaks are especially vulnerable. If a sink is on an exterior wall and the cabinet feels cold, that area deserves extra caution. Homes in Wantagh, Seaford, Massapequa, Merrick, Levittown, Bellmore, Freeport, and nearby Long Island towns can see sudden cold snaps that turn small insulation gaps into expensive pipe problems.
How to prevent frozen pipes
Insulate exposed pipes, seal drafts around penetrations, disconnect garden hoses, shut off and drain exterior hose bibs when possible, keep garage doors closed, and maintain steady indoor heat. During severe cold, open cabinet doors under sinks on exterior walls so warm air can reach the pipes. Letting a faucet drip slightly may help vulnerable lines during extreme cold, but it is not a substitute for insulation and draft control. Know where your main shutoff valve is before winter, because searching for it during a leak is peak human comedy.
What to do if a pipe freezes
If a faucet will not run during freezing weather, keep the faucet open and warm the area gently. Use warm towels, a hair dryer, or safe room heat. Never use an open flame. If you suspect the pipe has burst, shut off water and call a plumber. Watch for leaks as the line thaws. Sometimes the pipe splits but ice temporarily blocks the opening. Once the ice melts, water can escape quickly. That delayed leak is why frozen-pipe situations should be handled carefully.
Winter water heater and drain issues
Cold weather also increases demand on water heaters. Incoming water is colder, so the system works harder to deliver the same comfort. Sediment, aging parts, and undersized units become more noticeable in winter. Drains can also struggle when holiday cooking grease, heavy laundry, and guests increase usage. Keep grease out of sinks, monitor water heater noise or leaks, and address slow drains before a house full of people starts using every fixture like it is a stress test.
A simple winter plumbing checklist
Before winter, check exposed pipes, exterior faucets, shutoff valves, basement drains, water heater condition, sump areas if present, and any fixture on an outside wall. Keep Sal Manzo Plumbing, Heating & Cooling’s number handy for leaks, frozen pipes, drain backups, and water heater problems. Winter preparation is not exciting, but neither is paying for ceiling repair because a pipe split over the dining room. Maintenance remains boring because it works.

Frequently Asked Questions
How do I keep pipes from freezing?
Insulate exposed pipes, seal drafts, disconnect hoses, drain exterior lines when possible, keep heat on, open cabinet doors during cold snaps, and know where the main water shutoff is. Pipes in exterior walls, garages, crawl spaces, and basements need the most attention.
What should I do if a pipe freezes?
Open the faucet, warm the area gently, and avoid open flames. Use safe heat such as warm towels or a hair dryer. If you suspect the pipe burst or water begins leaking during thawing, shut off the water and call a plumber.
Can frozen pipes burst after they thaw?
Yes. Ice can temporarily block a split pipe. Once the pipe thaws, water may begin leaking quickly. That is why frozen pipes should be watched closely and why the water supply should be shut off if a burst is suspected.
Should I let faucets drip in cold weather?
A slow drip can help vulnerable pipes during extreme cold because moving water is less likely to freeze. It should be used as a temporary cold-snap measure, not a replacement for insulation, draft sealing, and proper winter plumbing protection.
