Average Ottawa Pricing for a Garage and Basement Epoxy Combo

Combining your garage and basement into a single epoxy project is one of the smartest ways to save money in Ottawa. The average contractor quote for a garage-plus-basement combo in the Ottawa market runs between $4,500 and $12,000, depending on total square footage, concrete condition, and the coating system selected. Most contractors offer a 10 to 20 percent discount on the per-square-foot rate when you bundle both spaces, compared to pricing them as separate projects.

A typical combo project involves a two-car garage (400 to 600 square feet) and a finished or unfinished basement floor (300 to 800 square feet), giving a combined area of 700 to 1,400 square feet. At the discounted combo rate, you are looking at roughly $6 to $10 per square foot for a mid-range flake or solid-colour system with proper surface preparation and a clear topcoat. That compares to $7 to $12 per square foot if you had each space quoted individually — the savings add up to $700 to $2,800 on a typical project.

The discount exists for good reason. When a contractor mobilizes equipment — diamond grinder, vacuum system, mixing tools — to your home, the setup and teardown time is the same whether they coat one room or three. Crew travel time, vehicle costs, and administrative overhead are absorbed once rather than twice. Material purchasing in larger quantities also means better pricing from suppliers. Some Ottawa contractors even offer a further discount if you let them schedule the basement portion during a slower week, giving them scheduling flexibility.

There are a few important planning considerations for a combo project. Your garage and basement may need different coating systems. A garage floor takes extreme abuse from road salt, hot tires, and freeze-thaw cycles, making 100 percent solids epoxy with a polyaspartic topcoat the ideal choice. A basement used as a family room or home gym may benefit from a metallic or decorative flake finish with a different colour palette. Good contractors will customize each space while still giving you the combo discount on the overall labour and mobilization.

Moisture management differs between the two spaces. Your Ottawa basement almost certainly has higher moisture vapour transmission than the garage, especially during spring snowmelt when the water table rises. A professional moisture test ($150 to $400) should be performed in both areas. If the basement requires a moisture mitigation primer, that adds $2 to $5 per square foot to the basement portion — a cost that should be clearly broken out in the quote so you understand what you are paying for.

Scheduling typically works like this: the contractor preps and coats the garage on day one, then moves to the basement on day two or three, depending on cure times and crew size. A polyaspartic system might allow both spaces to be completed in a single day. Traditional epoxy usually requires two to three days for the full combo. Either way, the project is done in one mobilization rather than two separate visits weeks apart.

When gathering quotes, ask each contractor to provide line-item pricing for each space plus the combo discount, so you can compare apples to apples.
