What is the typical square footage pricing for a townhouse garage epoxy in Barrhaven?

Great question — Barrhaven townhouse garages are one of the most common epoxy projects we see in Ottawa's south end, and the pricing is pretty straightforward once you understand what goes into it.

What to Expect for Epoxy Pricing in a Barrhaven Townhouse Garage

A typical attached townhouse garage in Barrhaven runs between 180 and 280 square feet for a single-car space, though some of the newer builds in communities like Half Moon Bay, Stonebridge, and Longfields push closer to 300 square feet with tandem or oversized layouts. That size range puts you squarely in the most common residential epoxy bracket for Ottawa.

For a standard water-based epoxy system — which is the entry-level professional option — you're looking at roughly $3 to $7 per square foot installed, putting a typical Barrhaven townhouse garage in the $540 to $1,960 range depending on floor condition and finish. That said, water-based epoxy is a thinner film product and honestly not the best long-term choice for a garage that sees Ottawa winters, road salt, and snowmelt tracked in from the driveway.

The more appropriate system for a garage floor in this climate is a 100 percent solids epoxy, ideally with a flake broadcast and a urethane or polyaspartic topcoat. That combination gives you a film thickness of 8 to 12 mils, excellent chemical and salt resistance, and the texture needed to prevent slipping on wet floors — which is a real concern in Ottawa garages from November through April. For that full system, expect to pay $6 to $12 per square foot, putting a 220-square-foot Barrhaven garage in the $1,320 to $2,640 range. If you upgrade to a polyaspartic system, which cures faster and performs better in low temperatures, pricing moves to $8 to $15 per square foot, or roughly $1,760 to $3,300 for the same space.

One cost factor that catches a lot of Barrhaven homeowners off guard is concrete preparation. Many of the townhouse builds in that area — particularly anything from the mid-2000s through the 2010s construction boom — have garage floors with surface contamination from construction oils, existing sealers, or minor cracking from frost heave. If the contractor needs to diamond grind the surface (which they absolutely should — no professional skips this step), or fill cracks and spalls before coating, add $2 to $5 per square foot to your budget for that prep work. Proper mechanical surface preparation is non-negotiable for adhesion, and it's one of the most common places where cheap quotes cut corners.

From a seasonal timing standpoint, spring and early fall are ideal for Barrhaven garage projects. Most attached townhouse garages in that area are unheated, so you need ambient and slab temperatures above 10 degrees Celsius throughout the application and cure period — typically 5 to 7 days for vehicle traffic. That means April through October is your practical window, with May and September being particularly good months when humidity is manageable and temperatures are stable.

Moisture testing is essential before any coating goes down. Barrhaven sits on clay-heavy soil in several pockets, and spring snowmelt can push significant vapour through concrete slabs. A calcium chloride test or relative humidity probe should confirm moisture vapour emission below 3 pounds per 1,000 square feet per 24 hours before application begins.
