Frequently Asked Questions
Which cracks are worrying?▾
Horizontal cracks, stair-step cracks in block walls, cracks that widen over time and cracks that let water through. A fine, stable vertical crack is generally benign.
Is excavation always required?▾
No. An isolated crack in a stable wall is often repaired by injection. Excavation is called for when the wall is at fault over a larger area or the drain must be replaced.
When is an engineer needed?▾
With settling, a horizontal crack or progressive movement, and before major work. The report frames the work and protects your investment.
How do I compare quotes?▾
By starting from a shared diagnosis. Otherwise you are comparing solutions to different problems.
What warranty should I require?▾
A written warranty on the repair, with its term and exactly what it covers, plus proof of insurance and the CNESST clearance.
Foundation & Waterproofing in Quebec: what to know
Foundation problems almost always announce themselves through basement water or a crack. The right reflex is not to pick a solution but to establish the cause first.
Not all cracks are equal
A fine vertical crack in a concrete wall is common and often benign. A horizontal crack, a stair-step crack in a block wall, a crack that widens or lets water through are another matter and deserve a professional opinion.
Water before concrete
Downspouts discharging at the wall, a lot sloping toward the house, a blocked weeping tile: those three causes explain a large share of damp basements, and they are corrected without major work.
When an engineer becomes necessary
With settling, a horizontal crack or movement that is progressing, an engineer's report defines the problem and lets you compare quotes on the same basis. Without it, each contractor proposes their own solution and the prices mean nothing.
Licence
The contractor must hold a Régie du bâtiment du Québec licence, liability insurance and a CNESST clearance. Require a written warranty on the repair.
