How to Prevent Frozen Pipes

  1. Reroute and / or insulate exposed pipes on the exterior walls, and in attics and crawl-spaces.
  2. Winterize your property during late summer, early fall.
  3. Maintain your boiler regularly.
  4. Turn up your hot water heater during severely cold climates.
  5. Open the faucets slightly during freeze periods to keep it moving in the pipes.
  6. Open doors in rooms with no heat to help warm air from other rooms to circulate.
  7. Invest in a hot water heater blanket.
  8. Shut off the main water supply if you will be away from home for more than 2 days.
  9. Leave the central heating on if you will be away.
  10. Pack away hoses and turn off outdoor water supply.

What to Do if Your Pipes Freeze

  • Turn off the main water supply to help prevent water damage.
  • If you have a burst pipe, turn off the electrical supply and don’t go into the basement.
  • DO NOT use any open flame to thaw your pipes.
  • Ask a neighbour if you could use their bathroom temporarily.
  • DO use a small hair dryer or space heater to heat the area (but don’t leave it unattended!)
