Basement Water Leaks? Here’s What Every Toronto Homeowner Should Know Before It Gets Worse

A water leak in the basement isn’t just annoying—it can be the start of something much bigger. Whether it’s a little trickle after a rainfall or a full-blown flood during a storm, water in your basement is a sign your home is trying to tell you something.


If you’ve been putting it off, hoping it’ll fix itself—trust us, it won’t. But the good news is: there are real, effective solutions. And if you live in Toronto or the GTA, you’ve got options—including subsidies and expert help from local pros who do this every day.

Let’s walk you through what’s really going on under your home—and how to fix it for good.

Why Is There Water in My Basement?

Toronto homes, especially the older ones, often have aging foundations and outdated drainage systems. A water leak in basement walls or floors can come from:

  • Cracks in your foundation
  • High groundwater pressure
  • Clogged weeping tile
  • Failed sump pumps
  • Sewer backups from city lines

And once that water gets in, it doesn’t just damage your walls and floors—it can lead to mold, foundation shifting, and even health issues.

Foundation Repair: Stop the Problem at Its Core

When water is seeping through your basement walls, it usually means it’s time to repair foundations. Toronto homes are often built on clay-heavy soil, which expands and contracts with moisture. That movement can crack foundations over time.

At Canada Waterproofers, we handle all types of foundation repair—from epoxy injections for small cracks to full exterior excavations for deeper structural problems. We don’t believe in band-aid fixes. We believe in solving the issue from the ground up—literally.

How Much Does It Cost to Waterproof a Foundation?

Let’s talk numbers—because that’s the first thing on most people’s minds.

The cost to waterproof a foundation can vary depending on your home and the method used:

  • Interior waterproofing systems (good for finished basements): $70–$190 per linear foot
  • Exterior waterproofing (the long-term fix): $100–$350 per linear foot
  • Smaller crack repairs: $400–$800
  • Sump pump or backwater valve additions may be extra

The best way to know what it’ll cost for your home is with a free inspection—we’ll show you what’s going on and give you a clear, honest quote with no pressure.

Sewage Backup? You May Need a Back Flow Valve Sump Pump

If you’ve ever dealt with sewage backing up into your basement during a storm, you know how awful it can be. That’s where a back flow valve sump pump setup becomes your home’s unsung hero.

A backwater valve blocks sewage from backing up through your floor drains, while the sump pump handles groundwater buildup. Together, they protect your home from two major threats.

And what about the backwater valveinstallation cost in Toronto?

  • Expect a range between $2,000 and $3,500, depending on your plumbing setup
  • Good news: the City of Toronto offers up to $1,250 in rebates under the Basement Flooding Protection Subsidy Program
  • We’ll help with the paperwork so you don’t have to stress
