How much does foundation crack repair cost in Vancouver?

Foundation crack repair in Vancouver costs $250 to $700 per crack for interior injection and $1,500 to $4,000 per crack for exterior excavation and repair — with the right method depending on the crack type, the foundation material, and whether water is actively leaking through. Most hairline to moderate cracks in poured concrete foundations can be repaired effectively from the interior using injection, while structural cracks, stone foundations, and recurring leaks may require exterior work.

Interior crack injection is the most common repair method for poured concrete foundations across Metro Vancouver. The process involves cleaning the crack, installing injection ports along its length, and injecting either epoxy or polyurethane under pressure to fill the crack from front to back. Epoxy creates a rigid, structural bond that is actually stronger than the surrounding concrete — it is the preferred choice for structural cracks and dry cracks. Polyurethane foam is flexible, expands to fill irregular voids, and works well for actively leaking cracks because it cures even in wet conditions. Most injection repairs cost $250 to $700 per crack in Metro Vancouver, depending on the length and accessibility. A typical basement might have two to five cracks that need attention, putting the total at $500 to $3,500.

Not all cracks are equal, and understanding the difference is important. Hairline cracks (less than 1/16 inch wide) are extremely common in poured concrete foundations and are usually caused by normal curing shrinkage. They rarely indicate structural problems but can allow water infiltration in Vancouver's heavy rainfall — injection repair is straightforward and cost-effective. Vertical cracks wider than 1/8 inch may indicate settlement and should be assessed by a structural engineer before repair. Horizontal cracks are the most concerning — they indicate lateral pressure from soil or hydrostatic water pressure pushing against the foundation wall. Horizontal cracks, stair-step cracks in concrete block foundations, and any crack wider than 1/4 inch warrant a structural engineer's assessment ($500 to $1,500 for a foundation report) before proceeding with repair.

When Exterior Repair Is Necessary

Exterior crack repair involves excavating the soil away from the foundation wall down to the footing, cleaning and preparing the crack from the outside, applying a waterproofing membrane over the repair, and backfilling. This is significantly more expensive at $1,500 to $4,000 per crack because of the excavation labour, but it is the superior solution for cracks that have failed previous interior injection, for cracks in stone or rubble foundations that cannot hold injection material, and for situations where the exterior waterproofing membrane is compromised. If you are already excavating for weeping tile replacement or exterior waterproofing, repairing cracks at the same time adds relatively little marginal cost.

Vancouver's climate makes foundation crack repair more urgent than in drier regions. With over 1,200mm of annual rainfall and sustained hydrostatic pressure against foundation walls for six to eight months of the year, even a small crack can allow significant water infiltration over time. A crack that weeps slightly during a heavy November rainstorm will get worse — water follows the path of least resistance, and freeze-thaw cycles (even Vancouver's mild version above the frost line) gradually widen cracks. Repairing cracks before finishing a basement is essential — sealing water entry points behind drywall is a guaranteed path to hidden mould growth.

For homes in North Vancouver and West Vancouver, where heavy rainfall combines with hillside runoff and significant hydrostatic pressure on the uphill foundation wall, crack repair should be part of a comprehensive waterproofing assessment. A single crack repair may solve the immediate leak, but if the weeping tile system is clogged or the exterior waterproofing has degraded, water will find another path in. Similarly, homes in Richmond and Delta with high water tables may experience cracks leaking during peak groundwater season even if they were dry all summer — seasonal testing helps identify these issues.

Most reputable waterproofing contractors in Metro Vancouver offer warranties on crack injection repairs — typically 10 to 25 years for the injection itself. Ask for a written warranty that covers both the material and labour for re-repair if the crack leaks again. For structural crack repairs, ensure the work is designed or reviewed by a structural engineer, particularly if you plan to finish the basement afterward — the BC Building Code requires that structural integrity be maintained, and any modifications near structural cracks need professional oversight.
