Reliable Basement Waterproofing Contractor in Toronto & Nearby

Basements are prone to flooding by design since they are typically built below ground level. Basements often flood during times of heavy rain or snowmelt, but flooding can happen even during dry weather. Aside from flooding in your neighborhood or a plumbing leak, there are several other sources of water in the basement, including surface water, groundwater, or sewer water backup. Surface water from overflowing gutters or sloped pavement or landscaping can pool next to the foundation and seep or leak into the basement. When the groundwater level rises above the level of the basement floor, hydrostatic pressure pushes water through cracks in the foundation. An overwhelmed sewer system or clogged sewer line can cause a backup of water in the basement.

When your basement floods, call a restoration contractor who can help with cleanup, then have your home inspected by a basement waterproofing professional. We can provide a no-charge evaluation and design a custom waterproofing solution to prevent future water damage.

Depends. The source of your wet basement problem will determine the best approach to waterproof your basement. Sometimes, the solution to a wet basement is as simple as keeping water away from the foundation with high-quality gutters and proper yard grading. Many homeowners try DIY, off-the-shelf solutions for a quick, temporary fix. But if entire walls are wet, water is coming up through the floor, or there's standing water in the basement during heavy rain, it might be time for a long-term, permanent solution, including a heavy-duty sump pump and interior drainage system installed by a waterproofing contractor.
