Prevent water damages from outside

Water damage is the leading cause of home insurance claims in Quebec. Here is some advice to prevent water damages from outside your home.


  • Each year, check the condition of your roof.
  • Have it inspected by a professional if it's more than 20 years old.

Drains, eaves troughs and downspouts

  • Make sure downspout extensions are directed at least 1.8 metres away from your home's foundation walls. And make sure the water doesn't flow towards your neighbour's home. Downspout extensions should be directed away from your house towards the road, back yard or back lane.
  • Make sure they're not clogged; for example, clear dead leaves from eaves troughs in the fall.

Door and window caulking

  • Once a year, check the caulking. Joints that have lost their seal can cause water infiltration.

Basement window wells

  • Inspect them to make sure no water has accumulated.

Outside faucets

  • In the fall, turn off the water supply and drain garden hoses.

Foundation walls

  • Once a year, check foundation walls for cracks and seal any immediately.


  • Make sure the leveling of your land is adequate. A slope of land, even slight, can promote an excess of water around the foundations and increase the risk of flooding.

Rain barrels

  • Help reduce the risk of water seeping into your basement.
  • Help reduce water usage and provide a ready supply of non-chlorinated water for your lawn and garden.
