How much does it cost to epoxy a basement floor in an Ottawa bungalow

Basement Epoxy Costs for Ottawa Bungalows

Epoxying a basement floor in a typical Ottawa bungalow will cost between $3,600 and $10,500 professionally installed, depending on the size of the basement, the coating system you choose, and the condition of your existing concrete. Most Ottawa bungalows have basements ranging from 600 to 900 square feet, and at current 2025–2026 rates of $6 to $14 per square foot, that range covers everything from a basic solid-colour epoxy to a premium decorative flake or metallic system.

A solid-colour 100 percent solids epoxy is the most popular mid-range option for Ottawa bungalow basements. It produces a thick, durable film of 8 to 12 mils in a single coat and holds up extremely well against foot traffic, furniture scuffs, and the occasional basement moisture that Ottawa homes are notorious for. For a 700-square-foot bungalow basement, expect to pay roughly $4,200 to $7,000 for this type of system, including diamond grinding, crack repair, and a urethane topcoat. Water-based epoxy brings the cost down to $3,600 to $5,600 for the same area, though the thinner film means it will not last as long under heavy use.

The single biggest variable in Ottawa basement epoxy pricing is moisture mitigation. Bungalows built before the 1980s often lack modern vapour barriers beneath the slab, and Ottawa's high water table combined with spring snowmelt can push moisture vapour through the concrete at rates that cause coating failure. If your contractor's calcium chloride test or relative humidity probe test shows moisture vapour emission above 3 pounds per 1,000 square feet per 24 hours, you will need a moisture-blocking primer or vapour barrier epoxy applied first. This adds $2 to $4 per square foot to the project but is absolutely essential — skipping it is the number one cause of peeling basement epoxy in Ottawa.

Concrete condition also affects cost significantly. Older bungalow basements in neighbourhoods like Alta Vista, Westboro, or the Glebe may have decades of cracks, spalling, and surface contamination from old paint or tile adhesive. Diamond grinding to create a proper concrete surface profile (CSP 2 to 3) is standard, but extensive crack filling, spall repair, or old coating removal can add $2 to $5 per square foot on top of the coating price. Your contractor should include a detailed floor assessment in their quote so there are no surprises.

One advantage of basement work is that it can be done year-round in Ottawa, unlike garage floors. Since your bungalow basement is climate-controlled, temperatures stay well above the 10-degree Celsius minimum that epoxy requires for proper curing. This means you are not limited to the April-through-November window and can often get better pricing during the slower winter months when contractors have more availability.

Before committing, get at least three written quotes and confirm each contractor carries WSIB coverage and a minimum of $2 million in liability insurance.
