Flood prevention

During periods of heavy rain, a residence may suffer water damage due to flooding, runoff, an equipment breakdown, or a sewer back-up.

Regular inspections of your property are recommended to keep it in good condition, identify any problems, and make the necessary repairs.

As such, standards and by-laws must be respected. Preventive measures can also be taken.

  1. Exterior cladding
    • Perform regular visual inspections of cladding, foundations, and caulking to identify any problems, and have the necessary repairs done by a professional.
  2. Gutters and downspouts
    • Extend downspouts to divert water away from foundations and the basement garage entrance, where applicable.
  3. Sloped yards
    • Build up the yard to divert water away from the residence.
  4. Sump pump
    • Inspect it annually to make sure it is working properly.
  5. Check valve Check valve
    • A check valve is a simple device that forces water to flow in a single direction, toward the municipal sewers. A check valve has a hinged flap that closes when water tries to flow in the opposite direction, protecting your home.
    • In accordance with municipal by-law CM-2005-382, this mandatory device must be installed on all horizontal pipes to devices that receive wastewater, such as plumbing equipment, floor drains, retention tanks, oil separators, tanks, interceptors, and other pipes or drains installed in basements or cellars. Squeeze-in check valves are not permitted as replacement check valves on horizontal pipes, as stipulated in by-law CM-2005-382.
  6. Garage door below street level
    • In compliance with municipal by-laws, a garage door below street level must feature a raised portion to avoid collecting run-off from the street.

If your property is accidentally damaged due to flooding, you are encouraged to consult the Canada Mortgage and Housing Corporation website for more information.
