How to Prevent Frozen Pipes This Ottawa Winter

By August 30, 2025No Comments

Ottawa winters can be brutal on your plumbing system. With temperatures regularly dropping below -20°C, frozen pipes are a common concern for homeowners across the National Capital Region.

Why Do Pipes Freeze in Ottawa?

When water freezes, it expands by about 9%, creating tremendous pressure inside your pipes. This pressure can cause pipes to burst, leading to expensive water damage.

Tips to Prevent Frozen Pipes

  • Insulate pipes in unheated areas like basements, crawl spaces, and garages
  • Keep cabinet doors open to allow warm air to circulate around plumbing
  • Let faucets drip slightly during extreme cold snaps
  • Maintain indoor temperature above 15°C even when away
  • Disconnect and drain outdoor hoses before winter
