How to Prevent Frozen Pipes During a North NJ Winter

By Rosado Plumbing & Heating · January 12, 2026

When temperatures drop into the teens across Bergen County, NJ, unprotected pipes are at risk. A frozen pipe can burst and release hundreds of gallons of water into your home. Here’s how to protect yours.

Before the cold hits

  • Insulate exposed pipes in basements, crawl spaces, garages, and along exterior walls.
  • Seal drafts near pipe runs — even a small gap lets freezing air in.
  • Disconnect garden hoses and shut off outdoor spigots.
  • Know where your main water shutoff is, so you can act fast if something bursts.

During a deep freeze

  • Let a pencil-thin trickle of water run from faucets on exterior walls overnight.
  • Open cabinet doors under sinks to let warm air reach the pipes.
  • Keep your heat on, even when you’re away — never below 55°F.

If a pipe freezes

  • Keep the faucet open so water can escape as the pipe thaws.
  • Apply gentle heat with a hair dryer or towels soaked in warm water — never an open flame.
  • If a pipe has already burst, shut off the main and call us right away.
