Diagnosing & Repairing Foundation Damage

The foundation of your home must be reliable, solid, and strong enough to carry the rest of the structure. Although foundations are built of strong concrete, they shift, expand and contract over time due to changes in temperature and moisture in the soil. This can cause the concrete to crack or corrode — issues that must be attended to so that major structural problems don't arise.

Neglecting the foundation of your house can be one of the most expensive mistakes you can make when it comes to home repair and renovation. Maintaining your house's foundation should be a priority! At the first signs of leaking water, moldy walls, or a musty smell in your basement, give us a call — small problems can put your entire house at risk for more serious issues.

Types of Foundation Damage

Not all foundation cracks are created equal. We diagnose the specific type of movement affecting your Toronto home and implement the precise structural repair required.

Non-Structural Cracks

Typically caused by concrete shrinkage during curing or minor settling over time.

  • Vertical or diagonal cracks
  • Less than 1/8 inch wide
  • Often leak water but don't threaten stability

Structural Cracks

Caused by water pressure, soil movement, or major foundation settling.

  • Horizontal cracks or stair-step patterns in brick
  • Cracks wider than 1/4 inch or growing
  • Accompanied by bowing walls or sticking doors

The Danger of Band-Aid Fixes

Many contractors offer quick crack injections from the inside. While these might stop a leak temporarily, they don't address what's actually causing the problem — and the crack will likely return.

A crack is a symptom. If you only treat the symptom, the wall will continue to move. We excavate to relieve the exterior pressure, repair the wall permanently, and install proper exterior drainage so the problem never returns.

Time, water, shoddy building materials, and improper maintenance around your house can all contribute to foundation damage — a problem that extends upward into your entire house, leading to plumbing and gas line damage, damage to insulation and interior walls, cracked or sloping walls and floors, and devaluation of your home.

Quick FAQ

Foundation Repair FAQs

Have concerns about a crack you found or a door that won't shut? Find answers to common questions about structural damage and repair costs.

How do I know if a foundation crack is structural?

Horizontal cracks, stair-step cracks in brickwork, cracks wider than 1/4 inch, or any crack that leaks water during heavy rain are warning signs of structural issues. Other indicators include bowing walls, doors and windows that stick, sloped or uneven floors, and new drywall cracks appearing upstairs. We provide a free structural assessment where we measure crack widths, check for wall movement, and determine whether you need monitoring, simple sealing, or full structural repair with reinforcement.

Why is excavation better than a quick interior crack fix?

Quick interior crack fixes often don't address the root cause. If the foundation wall is still moving or water is still pushing against it, those cracks will reopen or new ones will form. We excavate to expose the exterior foundation, repair cracks properly from the outside, and install waterproofing and drainage systems. This permanent approach stops water intrusion, stabilizes the structure, and is backed by our 20 year warranty.

How much does structural foundation repair cost?

Foundation repair costs vary based on the extent of damage, wall height, excavation requirements, and waterproofing scope. After our free inspection, we provide a clear quote showing exactly what work is needed and why. Proper repairs are a permanent investment in your home.

Should I repair foundation cracks before selling my house?

Absolutely. Unresolved foundation cracks, bowing walls, or signs of settlement are major red flags for buyers, home inspectors, lenders, and insurance companies. Taking care of the repair now, with proper documentation and a transferable 20 year warranty, eliminates objections, proves structural integrity, and protects your home's value. Buyers are far more confident purchasing a home with documented repairs than one with visible foundation issues.

What causes foundation cracks in Toronto homes?

Toronto's clay-heavy soil expands when wet and shrinks when dry, placing constant pressure on foundation walls. Freeze-thaw cycles make this worse — water seeps into small cracks, freezes, and forces the crack wider over time. Homes built before 1980 are especially vulnerable because original waterproofing and drainage systems have likely deteriorated. Tree roots near the foundation and poor surface grading also contribute to cracking and settlement.
