10 Ways to Prevent Basement Floods Before They Start

Clogged gutters and downspouts can cause water buildup, which may then leak into your basement. Regularly remove leaves and other debris, so your gutters and downspouts drain properly.

When it’s raining, walk around your house to see where the water exits your gutters and downspouts. If you need to, change the angle of your downspouts or extend them so that the water drains further away from the foundation. The ideal distance is two metres.

When water from the downspouts pours into the sewer system, it can overtax your sewers and cause flooding. If you can do it without affecting the neighbouring properties, disconnect your downspouts from the sewer system and let the water drain into your garden.

When water enters your home through roof leaks, it may make its way down into the basement. Check your roof regularly for signs of damage and fix any leaks ASAP.

When the land around your home slopes towards the foundation walls, water will build up against the foundation and leak into your basement. Check that the grading is sloped away from your house instead.

Green space helps to absorb water and improve drainage, so increase the greenery around your home by planting shrubs and other flora. Pick plants that are native to your area, as they are the more environmentally responsible option. For inspiration, check out these native plants in Canada, broken down by province.

Check your external drainage system for blockages and leaks. Repair damage if you find any.

To prevent leaks from your home’s plumbing system, keep all the pipes in good working order. Prevent blockages by using toilets, showers, bathtubs and sinks the way they’re supposed to be used – without flushing or washing away anything that you shouldn’t.

Even small cracks in your home’s foundation, walls, windows, floors or the basement door can allow enough water to enter and cause serious damage. Check for and seal any holes and cracks.

If you’re living in an area that is prone to flooding, it’s well worth investing in a sump pump system that can remove any accumulated water. Have a qualified plumber install it for you and have a backup power system in case of power failure.
