Some foundation problems are structural rather than a matter of water: a wall that has moved, a footing that has settled, or damage that affects what the foundation carries. The City of Ottawa lists "Structural foundation repairs and drain tile replacement" and "Structural repairs or alterations" as work that needs a building permit.
Excavating next to a foundation is a contractor duty under Ontario's construction safety regulation: if an excavation may affect the stability of an adjacent building, an engineer specifies the precautions in writing (O. Reg. 213/91, s.229). Ask whether an engineer is involved in your repair.
Below-grade masonry walls get at least 6 mm of mortar parging coved over the footing before dampproofing or waterproofing (O. Reg. 163/24, 9.13.2.3 and 9.13.3.3). Brick and stone above grade, chimneys and repointing are masonry work for a masonry contractor.
We found no two independent published sources that agree on a structural repair price, so no range is shown. Prices depend on the cause, the design and the permit.
