We hold no licence to check for this category, so insurance and WSIB clearance are what a homeowner compares. That says what we hold, not what the province requires: nobody here has checked whether Ontario licenses this work.
Basement water diagnosis and repair. Quotes state the suspected cause and rule out grading and downspouts before proposing excavation.

Check on record out of dateThe record says this was checked with the Private insurer on Mar 27, 2026, about 5 months ago, past the 120 days we treat as current. Valid until Mar 31, 2027, 221 days from today.

Crack injection at the low end, full exterior excavation at the high end. Excludes landscaping restoration and finishing the basement afterward.
Demand and price peak in spring. Booking outside it is the cheapest saving available on this job.
Each of these has a specific answer. A vague answer to a specific question is the information.
This work usually needs a municipal permit. Confirm in writing who pulls it. A contractor who offers to skip it is offering you a disclosure problem at resale and a declined claim if something goes wrong.
