In 2026 a single crack injection typically costs $400 to $800, and most homes need two to four cracks done. Exterior waterproofing runs about $150 to $300 per linear foot. Your quote depends on wall type, access and how many cracks there are.
Usually not. Thin vertical cracks in poured concrete are normally shrinkage cracks and only a water problem. Horizontal cracks, stair-step cracks in block, cracks wider than about 6 mm, or a wall that bows inward should be looked at, and may need a structural engineer.
The spring melt saturates the soil around the foundation, and Ottawa's Leda clay drains slowly, so water sits against the wall for weeks. Freeze–thaw cycles over the winter also open existing cracks. A crack that was dry in August can leak in April.
Polyurethane is the usual choice for a leaking crack because it stays flexible and seals even when the crack is damp. Epoxy is used when the crack is dry and the goal is to bond the concrete back together. We pick based on the crack, and tell you why.
Yes. Every job includes before-and-after photos, a description of the repair and an itemized invoice, which is what most insurers ask for. Call early; spring is the busiest season.
Interior injection can be done year-round as long as the basement is heated. Exterior excavation is best from late spring to late fall, before the ground freezes.
