How to Prevent Frozen Pipes During New Jersey Winters

Frozen pipes are one of the costliest home disasters in NJ winters. Learn how to protect your plumbing before temperatures drop below freezing.

Every winter in North Jersey, homeowners learn the hard way that frozen pipes are no minor inconvenience. A burst pipe can release hundreds of gallons of water in a matter of hours, causing thousands of dollars in structural damage. The good news is that with a little preparation, frozen pipes are largely preventable.

Why Pipes Freeze (and Burst)

Water expands as it freezes. When water inside a pipe freezes, it creates pressure between the ice blockage and the closed faucet. If that pressure has nowhere to go, the pipe ruptures. Pipes most at risk are those in unheated areas—exterior walls, uninsulated basements, crawl spaces, garages, and attics.

Before the Cold Hits: Preventive Measures

Insulate Exposed Pipes

Pipe insulation (foam sleeves or fiberglass wrap) is inexpensive and easy to install. Wrap any pipes running through unheated spaces—your basement, crawl space, garage, or along exterior walls. This is especially important for older Bergen County and Hudson County homes where pipes may run through original uninsulated spaces.

Seal Gaps and Cracks

Cold air infiltrating your home can freeze pipes even inside interior walls. Use caulk or spray foam to seal gaps around pipes where they pass through walls, floors, and ceilings—especially near dryer vents, electrical wiring, and other penetrations.

Know Where Your Main Shutoff Is

In an emergency, you need to be able to cut water to your home immediately. Locate your main water shutoff valve now—before there's a problem. Make sure every adult in your household knows where it is and how to use it.

During a Cold Snap

  • Keep your thermostat set to at least 55°F even when you're away—never turn the heat completely off in winter.
  • Open cabinet doors under sinks on exterior walls to allow warm air to circulate around the pipes.
  • Let cold-water faucets drip slightly on extremely cold nights—a trickle of water keeps pressure from building up.
  • Disconnect and drain outdoor hoses, and shut off outdoor faucets from the indoor valve.
  • Keep garage doors closed if there are water supply lines running through the garage.

If a Pipe Does Freeze

If you turn on a faucet and only a trickle comes out during cold weather, you may have a frozen pipe. Do not panic—but act quickly. Never use an open flame to thaw a pipe. Instead, use a hair dryer, electric heating pad, or warm towels wrapped around the pipe. Keep the faucet open as you apply heat so water can begin to flow as the ice thaws.
