What is the cost difference between epoxy and polished concrete for an Ottawa office

Comparing Epoxy and Polished Concrete Costs for Ottawa Commercial Offices

For an Ottawa office space, epoxy flooring and polished concrete are both excellent choices, but they differ meaningfully in upfront cost, long-term maintenance, and performance characteristics. Understanding these differences will help you make the right investment for your specific office environment.

Commercial epoxy flooring in Ottawa typically runs $8 to $18 per square foot installed, depending on the system you choose. A basic solid-colour epoxy with a urethane topcoat for a standard office sits around $8 to $12 per square foot, while a decorative flake or metallic system pushes toward $14 to $20 per square foot. These prices include proper surface preparation with diamond grinding, a primer coat, one or two coats of epoxy, and a protective topcoat. For a typical 2,000-square-foot Ottawa office, you are looking at roughly $16,000 to $36,000 for a professional epoxy installation.

Polished concrete, by contrast, generally costs $4 to $12 per square foot in Ottawa, depending on the level of polish and whether decorative scoring, staining, or dyeing is included. A basic grind-and-seal finish runs $4 to $6 per square foot, while a high-gloss mechanically polished floor with densifier and guard coats lands between $8 and $12 per square foot. That same 2,000-square-foot office would cost approximately $8,000 to $24,000 for polished concrete.

The cost picture shifts when you factor in long-term maintenance. Polished concrete requires periodic re-application of guard coats every one to three years, but daily maintenance is minimal — just dust mopping and occasional wet cleaning. Epoxy floors need recoating every 7 to 15 years depending on traffic, but the recoat cost is typically 50 to 60 percent of the original installation. Over a 20-year period, polished concrete often proves slightly more economical for low-to-moderate-traffic office environments.

Ottawa's climate plays a role in this decision as well. If your office has an entrance directly from outdoors, road salt and snowmelt tracked in during our long winters can dull polished concrete faster than epoxy. Epoxy with a urethane topcoat provides superior chemical resistance against calcium chloride and sodium chloride de-icing agents. For ground-floor offices or spaces with exterior vestibules, epoxy may justify its higher upfront cost through better salt resistance.

One important consideration specific to Ottawa office spaces is moisture. Many older commercial buildings in neighbourhoods like the Byward Market, Centretown, and Hintonburg have concrete slabs that emit moisture vapour at rates exceeding what standard coatings can tolerate. Both systems require moisture testing before installation, but epoxy with a moisture-mitigating primer can handle higher moisture levels than polished concrete sealers. Factor in an additional $2 to $4 per square foot for moisture mitigation if your slab tests above 3 pounds per 1,000 square feet per 24 hours.

For a clearer picture of what makes sense for your office, get a minimum of three written quotes from flooring contractors.
