A look at cracks that are wide, stepped, horizontal or growing, and a clear next step.
Much of Ottawa sits on Leda clay, the marine clay left behind by the Champlain Sea. It swells when wet and shrinks as it dries, and it can lose most of its strength when disturbed. Foundations on it move a little every year.
Add a climate that swings from about -35°C to +35°C, deep frost, and a spring melt that saturates the ground around every basement, and hairline cracks become wet cracks. Most calls come in March and April, when the snowbanks go and water finds the weak spot.
Most cracks are shrinkage cracks and are cheap to seal from inside. Some are not. We tell you which kind you have, and if it needs an engineer we say so before we quote. Insurers are asking more often for proof of repair at renewal, so every job comes with photos and a written invoice you can send them.
We serve Ottawa, Barrhaven, Orléans, Kanata, Nepean, the Glebe and Old Ottawa South.
How Ottawa's clay soils, frost and water put stress on foundation walls, how to tell a cosmetic crack from a structural one, and when to get it looked at.
