Severe weather events have become more common nationwide, specifically in Ontario. The most recent, an extreme rainfall event in July 2024, saw record-breaking flooding in Mississauga, along major highways, and in parts of Toronto including Union Station. Many homes and businesses sustained flood damage, leaving homeowners worried about the next extreme weather event.
As a homeowner, you can take the initiative to help floodproof your home and offer some protection against severe rainfalls before the next weather event occurs. Here are some guidelines from the experts to help you get started:
INSTALL A DRAINAGE SYSTEM
Installing a drainage system on your property is one of the best ways to channel water away from your home’s foundation. A proper drainage pipe installed under your lawn or garden may help prevent future flood damage, especially if the area outside tends to get soggy after heavy rain.
Determine where the water runs off and dig a trench toward that outlet. This area could be the curb or an existing water body but should not be directed towards a neighbour’s home. You can hire someone to do this or follow DIY instructions online. Also, consider adding drainage next to your driveway by installing channel drains, pavers, or gravel.
ADD POROUS OUTDOOR SURFACES
Consider changing your outdoor space to include porous surfaces. Instead of concrete or asphalt, install gravel or brick to encourage the water to seep into the ground. Use an absorbent mulch to manage heavy rain and add native plants to your gardens to help prevent erosion and improve water absorption. To collect water from downspouts, purchase a rain barrel. They are an inexpensive way to collect water during heavy rain and are an environmental solution for watering lawns and gardens during drier periods.
CLEAN DOWNSPOUTS REGULARLY
Downspouts can quickly become clogged with twigs, leaves, and other organic matter, specifically in areas with mature trees. Animals can also nest in downspouts or eaves, causing blockages. If you are comfortable cleaning them yourself, make it a habit to empty them in the spring and at the end of autumn when all the leaves have fallen. Or, hire a service to clean these for you. If you notice water overflowing from the eaves during a rainstorm, you may have a blockage that requires immediate attention.
RAISE HVAC EQUIPMENT
HVAC equipment such as air conditioners, propane tanks, boilers, and central heating are usually located outside or in your basement. These areas are the most vulnerable to water damage. A simple way to prevent damage is to elevate them to higher ground. It may not be possible to relocate them to another floor, but you can use building platforms to raise them off the ground if the risk of flooding is a concern. You may wish to consult with a contractor and an HVAC expert for more information and advice about doing this safely.
PROTECT YOUR FOUNDATION
In depressed areas, water can accumulate around your foundation and seep through cracks into your basement. You can help prevent this by sealing your foundation with a few simple steps:
- Apply a waterproof sealant (e.g., hydraulic cement) along the walls of your basement
and paint them with waterproof paint, such as epoxy paint, masonry paint, or acrolein
elasticized paint. - Install watertight shields for your windows and doors.
- Seal all cracks and holes with waterproof caulking.
- Consider installing flood vents that allow water to flow back outside if it enters your
- basement (consult a contractor).
GET FLOOD INSURANCE
Flood insurance is an excellent way to protect yourself financially if you are in an area prone to flooding. Check with your insurance broker about what options are available to you. Depending on where you live, your home insurance policy may or may not cover flood water from rain, so ensure your home insurance policy adequately insures you. Also, confirm whether there are any limitations or exclusions in your policy.
As severe weather events become more prevalent, it’s critical to take the necessary steps to help protect our homes. A small investment now could lead to huge savings later.
