Trade Playbook
Waterproofing is the trade nobody thinks about until the basement floods — and the business runs on a brutal truth: your failures show up years later, in someone's finished basement, and they get blamed on you. The questions: foundation versus restoration versus deck work, why building-science knowledge is the real moat, and how to survive the long-tail liability.

Waterproofing / foundation-repair contractor
Ontario figures for waterproofing, from the first day on site to the top of the trade. Approximate, and worth checking against current collective agreement rates and job postings in your region.
| Stage | Pay | What is going on at this stage |
|---|---|---|
| Labourer / crew | $20–28/hr | Excavation, prep, and membrane application. |
| Experienced waterproofer / applicator | $28–40/hr | Manufacturer applicator certifications raise your ceiling. |
| Foreman | More | |
| Waterproofing / foundation-repair contractor | Business income | Foundation repair is emergency, homeowner-direct, and high-margin. |
Two waterproofing contractors with the same ticket can be twenty dollars an hour apart because they picked different work.
New-build membranes and foundation repair — including the emergency, homeowner-direct wet-basement market.
Best for: People who want an accessible business with emergency demand.
Parking garages, balconies, and building envelopes — commercial, engineered, higher-value, often spec-driven.
Best for: People who want engineered commercial work.
Every figure above is what waterproofing contractors get paid. It is not what you charge once you run a waterproofing business. Your rate has to carry the hours you are not on the tools, the truck, the tools themselves, WSIB, insurance, the quote you wrote and lost, and the holdback sitting in someone else's account for 60 days. Contractors who set their rate off their old hourly wage are the ones who work every weekend and still cannot say whether the year was profitable.
The step from paid by the hour to paid by the jobEstimator, restoration project manager, building-envelope consultant, or owning a waterproofing/foundation-repair business. The diagnostic (building-science) skill is the bridge to the higher-paid envelope-consulting world — waterproofers who can explain why a building leaks, not just patch it, have the most valuable career off the tools.
Wage data, union rate sheets, and the places waterproofing contractors talk about money openly.
The rates above are the market. The live feed is the market this week: which builders and contractors just pulled a permit or won a contract in Ontario, what they are about to need, and who to call.
