How to Thaw Frozen Water Pipes

During the cold winter season, it is possible that water pipes may become frozen, so it is important to know how to thaw a frozen water pipe quickly and correctly.

Take these 3 simple steps to avoid a burst pipe and flooding:

Step 1: Find the frozen section of the pipe. (Frozen sections are often next to an exterior wall or where the water service enters the home).

Step 2: Open the nearest cold water faucet that the pipe feeds water into. This will lessen pressure in the system and let the water escape once you start thawing the pipe. You will know the pipe has thawed when the water starts flowing again.

Step 3: Use one of these methods to apply heat:

  • Wrap an electric heating pad around the frozen section of the pipe.
  • Use a hair dryer, pointing the heat at the frozen section of the pipe nearest to the faucet.
  • Position a portable heater so that the heat can reach the frozen pipe. Do not place the heater near any items that could catch fire.

If you have followed the above steps and the water pipe is still frozen, call 905-791-7800 for more help or to book a service call.  For more information about preventing and fixing frozen water pipes, please visit
