How to Know You’re in the Right Place

If you’re seeing any of the following signs, you’re not alone—and we can help:

Water pooling along basement walls or floor edges
Cracks in foundation walls or floors
Musty odours or visible mold
Water leaking from window wells
Damp drywall, peeling paint, or bubbling flooring
Sump pump struggling to keep up
Previous flood damage that wasn’t professionally repaired

These are symptoms of a larger waterproofing issue. We’re here to fix it right.

Our Basement Leak Repair Services

We handle all types of leaks—surface-level, structural, and everything in between. Each project starts with a thorough inspection to identify the real source of the problem.

Foundation Crack Repair

High-pressure polyurethane injection or epoxy seals cracks and prevents future seepage. Ideal for active leaks or visible damage.

Cove Joint Seepage Repair

Leaks where the wall meets the floor are caused by hydrostatic pressure. We install interior drainage systems or exterior footer drains to relieve pressure and stop the leak.

Window Well Leak Solutions

If water enters through or around basement windows, we install window well drains, covers, and sealed window units to prevent future flooding.

Floor Crack or Slab Leaks

Rising groundwater can push through the slab. We use perimeter drainage and sump systems to redirect water before it reaches your floor.

Sump Pump System Repair or Replacement

We diagnose sump pump issues, replace aging units, and install backup systems to keep your basement protected during storms and power outages.

Why Basement Leaks Are Dangerous to Ignore

Leaky basements don’t fix themselves. Left untreated, a minor leak can lead to:

Rotting wood and weakened framing
Electrical damage
Mold and indoor air quality issues
Damage to stored belongings
Permanent structural shifts

And the longer you wait, the more expensive it gets.

What Causes Basement Leaks in Toronto?

Toronto’s aging infrastructure, clay-heavy soil, and fluctuating water tables make basement leaks a common problem. The most frequent causes include:

Cracked or porous foundation walls
Poor drainage or grading around the home
Failing sump pumps
No vapor or moisture barriers
Hydrostatic pressure buildup below slab level
Clogged or non-existent window well drains

Every leak has a source. Our job is to find it and stop it at the root.
