| Item | Published range |

What the quote should say
- How many cracks, and where each one is
- The injection material (the Ottawa-area price pages list epoxy and polyurethane), and why
- Whether the price covers one crack or a set number
- What happens if the crack turns out to be part of a structural problem
- The warranty terms: what is covered, for how long, whether they transfer to a buyer
Permits
Crack injection is not named on either of the City of Ottawa's permit lists, so ask the City before the work starts. "Structural foundation repairs" are on the permit list.
City rebate
The City of Ottawa's Residential Protective Plumbing Program rebates protective plumbing devices (backwater valves, and sump pumps with battery backup). It does not list this work among its rebates.

Quick answers
When does a leaking crack become a permit question?
We found no City or Code statement that it is. The City lists "Structural foundation repairs" as permit work, so if a contractor says the crack is structural, ask about the permit and whether an engineer is involved.
Is crack injection on the City's rebate list?
No. The City's protective plumbing program rebates backwater valves and sump pumps with battery backup, not crack repairs.
