Frozen Pipes in NJ: Prevention, Thawing & What to Do If One Bursts

Northern New Jersey winters can be brutal. When temperatures drop below 20°F — which happens regularly from December through February — the risk of frozen and burst pipes increases dramatically. Knowing how to prevent, identify, and respond to frozen pipes can save you from thousands of dollars in water damage.

Why Pipes Freeze (and Burst)

Water expands as it freezes, creating tremendous pressure inside pipes. This pressure can crack or burst even metal pipes. Pipes most at risk are those that run through unheated spaces like exterior walls, uninsulated crawl spaces, garages, and attics.

Preventing Frozen Pipes Before Winter

• Insulate pipes in crawl spaces, attics, and exterior walls with foam pipe insulation
• Seal gaps in walls, floors, and foundation where cold air can reach pipes
• Disconnect and drain outdoor hoses and shut off exterior spigots from inside
• Keep cabinet doors under sinks open during cold snaps to let warm air circulate
• Allow a slow drip from faucets served by vulnerable pipes
• Keep your thermostat at 55°F or higher even when away

Safely Thawing a Frozen Pipe

Important: Never use an open flame. Electric heat guns, hair dryers, and heating pads are safe options. Always thaw from the faucet end toward the frozen section so steam can escape.
