Do You Need Foundation Crack Repair?

You might if you’ve noticed:

Water leaking through the wall or floor
Thin vertical or horizontal cracks getting wider
Musty basement smell or visible mold
Floor lifting or wall bowing
Cracks near windows or door frames
A damp or humid basement despite running a dehumidifier

We’ll identify the type of crack, find the root cause, and fix it properly.

What Causes Basement Cracks in Toronto?

Whatever the cause, we’ve repaired it before—and we’ll get yours fixed right the first time.

Hydrostatic Pressure

When groundwater pushes against your foundation

Soil Shifting & Settlement

Common in older homes and clay-rich areas

Poor Drainage or Grading

Directs water toward the home instead of away

Shrinkage or Thermal Stress

Concrete expands and contracts over time

Construction Defects

Thin walls, poor rebar placement, or missed expansion joints

Our Basement & Foundation Crack Repair Services

Epoxy & Polyurethane Injection

Best for vertical or diagonal cracks under 5 feet. We seal from the inside using high-pressure injection that prevents further water intrusion.

Exterior Crack Repair

For larger cracks or exterior breaches, we excavate to the foundation, seal the crack from the outside, and apply a waterproof membrane.

Structural Reinforcement

For horizontal or step cracks (often structural), we may install carbon fiber strips or recommend underpinning if movement is detected.

Drainage Solutions

If water pressure is the root cause, we’ll install a French drain, interior perimeter drain, or weeping tile system to divert moisture away.

Waterproofing Add-Ons

We offer sump pump installation, backup systems, window well drainage, and other waterproofing upgrades if needed during repair.

“We had a crack in the basement corner leaking after storms. Pavel found the source, gave us a quote on the spot, and had the crew fix it the next day. Clean, efficient, and totally dry ever since. Highly recommended.”
