February Thaw and Flood Protection

Wednesday Feb 21st, 2018


I was going to save this post for April but seeing that we are in the midst of an early thaw and experiencing plenty of rain in the GTA these tips should come in handy right now.


Storm Drains

  • Keep them clear of snow, ice, and debris to prevent flooding from happening if there is a rise in the temperature. This is particularly important during a thaw or come spring when one of the main causes of localized flooding is a blocked storm drain.


Melting Snow and Pooling Water

  • If snow is melting rapidly, it’s a good time to go outside and see how and where the water flows around your home. Check your eaves, downspouts, and surfaces in your yard that will point you toward flood-prone areas. Adjust downspouts to fix areas of pooling water, take note of patio stones that require releveling, and ensure the grading around your home slopes away from the foundation wall to help drain water away from your home (without negatively affecting neighbouring properties).
  • If water is pooling, it could quickly turn to a slippery ice patch during a freeze-up. Limit salt usage to protect buildings, wildlife, vehicles, clothing, vegetation, and pets; consider non-clumping cat litter or fireplace ashes. Shovel the snow first and then treat only the ice patches.


Check your Foundation Exterior and Interior Basement Walls

  • Seal cracks or openings in walls, floors, windows and foundations, and seal all window wells. Consult a professional if you do find a problem.
  • The City Of Toronto offers owners of single-family, duplex and triplex residential homes a subsidy of up to $3,400 per property to install flood protection devices. Eligible work includes: Installation of a backwater valve. Installation of a sump pump. Severance and capping of a home’s storm sewer or external weeping tile connection.


Check Your Water Meter

  • Keep a close eye on your water meter in winter when cracking or bursting pipes can be a concern. To check for leaks, simply turn off all the water in your home and then check the flow indicator on your water meter. If it is moving, you have a leak somewhere.
