What is the cost to install a stucco finish on a poured concrete garage in Kanata?

Applying stucco over a poured concrete garage is a popular upgrade in Kanata, where many homes—particularly in newer subdivisions like Arcadia, Richardson Ridge, and Kanata Lakes—have exposed concrete or block garages that look stark against the rest of the house. Stucco transforms the look and adds weather protection.

Pricing for Kanata Garage Stucco

A typical detached or attached two-car garage in Kanata has roughly 400–600 sq ft of exterior wall surface (excluding the door openings). Here's what you'd pay:

• Standard three-coat stucco over concrete: $4,000–$7,500- Acrylic/polymer-modified stucco: $3,500–$6,000- One-coat stucco system: $2,800–$4,500

Per square foot, you're looking at $8–$13/sq ft for traditional stucco and $6–$9/sq ft for acrylic systems. These are fully installed prices including surface prep, materials, and labour. Kanata pricing is generally in line with broader Ottawa rates.

Key factors that affect your garage project cost:

Surface preparation ($500–$1,500): Poured concrete needs proper prep before stucco adheres. The surface must be clean, rough enough for mechanical bond, and free of form-release oils. If the concrete is smooth (common with newer pours), it needs either mechanical scarification or a bonding agent. Some contractors apply metal lath over the concrete for best adhesion—this adds material and labour but produces the most reliable bond through Ottawa's freeze-thaw cycles.

Parging vs. full stucco: Many Kanata homeowners confuse parging with stucco. Parging is a single thin coat (usually 3/8") applied directly to concrete for basic protection and appearance—it costs $3–$5/sq ft and is simpler but less durable. Full three-coat stucco (7/8" total thickness) provides superior weather resistance and a much wider range of finish textures.

Insulation integration: If you're upgrading an uninsulated garage, you can install rigid foam insulation board with stucco applied over it (an EIFS-like assembly). This adds $3–$5/sq ft but brings your garage closer to the Ontario Building Code's energy efficiency recommendations—particularly relevant if you heat the garage or use it as a workshop.

Finish options at different price points:

• Sand float (most common): No extra cost—this is the standard finish- Dash texture: Add $0.50–$1.00/sq ft- Smooth/Santa Barbara: Add $1.50–$3.00/sq ft (requires extra finish coats)- Custom colour integral pigment: Add $0.75–$1.50/sq ft versus painting after

One Kanata-specific consideration: many newer garages sit on frost walls with exposed concrete below grade. Make sure your quote includes a proper base termination with a weep screed at least 4" above finished grade, and that any below-grade concrete gets proper waterproofing membrane rather than stucco, which will fail below the soil line. Most reputable Ottawa-area stucco contractors know this, but it's worth confirming in writing.
