CRACKED FOUNDATION IN TORONTO?

Foundation Crack Repair Toronto

A crack in your foundation is not something to wait on. Some are harmless shrinkage lines, but others let water in or signal a foundation that is moving. IcyReno has repaired foundation and basement cracks across Toronto since 2009, and we start every job by finding out which kind you actually have. Then we fix it properly, with engineer-backed methods and the right permit when the work calls for one. We repair:

  • Leaking cracks: sealed from the inside with epoxy or polyurethane injection to stop water for good.
  • Structural cracks: reinforced or underpinned when the crack points to a foundation problem.
  • Settlement cracks: stabilized so the movement stops instead of coming back.
  • Poured concrete and block foundations: repairs matched to how your Toronto home was built.

What Foundation Crack Repair Involves

Foundation crack repair seals and stabilizes cracks in your basement walls and footings so they stop letting water in and stop spreading. For a leaking crack, we inject epoxy or expanding polyurethane that fills the crack the full depth of the wall. For a structural or settlement crack, the fix goes further and may include exterior excavation, reinforcement, or underpinning. The right method depends on the crack, which is why we inspect first.

Types of Foundation Cracks We Fix in Toronto

  • Hairline cracks: thin shrinkage lines from concrete curing. Usually cosmetic, but worth watching if they widen or stain.
  • Vertical cracks: common in poured foundations and often the source of a leak during heavy rain. Injection is the standard fix.
  • Diagonal cracks: run at an angle, usually from a corner, and often point to uneven settlement that needs a closer look.
  • Horizontal cracks: the most serious. They form when soil pressure pushes on the wall and can mean the wall is starting to fail. These need professional assessment right away.
  • Stair-step cracks: follow the mortar joints in block foundations and usually signal settlement or shifting.

Crack Injection vs Exterior Excavation

Interior crack injection is fast, clean, and cost effective. We inject the crack from inside, it cures in the wall, and the leak stops, ideal for vertical and hairline cracks where water is the only problem. Exterior excavation is the more involved fix: we dig down to the footing, repair the crack from outside, and add membrane and drainage. It is the right call when a crack keeps coming back, when there are several cracks, or when the foundation needs structural work. After a free inspection we tell you which one your home actually needs, not the most expensive one.

Our Foundation Crack Repair Process

  1. Free inspection: we identify the crack type and the cause, not just the symptom.
  2. Honest recommendation: injection, exterior repair, or structural reinforcement, with a clear quote.
  3. The repair: done by our licensed crew, with a City of Toronto permit and engineered drawings when the work is structural.
  4. Protection: we pair the repair with drainage or waterproofing so water stops finding its way back in.

Foundation Crack Repair Cost in Toronto

A single interior injection on a straightforward vertical crack is at the low end. Multiple cracks, exterior excavation, or structural reinforcement cost more because there is more work and, in some cases, engineering and a permit involved. We give you a firm number after the inspection so there are no surprises. If the crack is tied to a bigger foundation issue, we will tell you that too, and walk you through underpinning or foundation waterproofing if that is what the house needs.

Foundation Crack Repair FAQ

It depends on the type. Hairline shrinkage cracks are usually cosmetic. Horizontal cracks, cracks that are widening, and cracks paired with sticking doors or sloping floors are signs of movement and should be assessed by a professional. When in doubt, a free inspection settles it quickly.

Yes. Most leaking vertical and hairline cracks are repaired from inside with epoxy or polyurethane injection that fills the crack through the full depth of the wall. Structural cracks and repeat leaks often need exterior work instead.

A single interior injection is often done in a few hours. Exterior excavation or structural repair takes longer because of the digging, reinforcement, and any permit or engineering involved.

Yes. IcyReno repairs foundation cracks across the City of Toronto, including North York, Scarborough, Etobicoke, East York, and the downtown core.
