What is the Cost to Spray Foam 1,000 Square Feet?
Spray foam is often the premium insulation choice on Alberta builds, and one of the first questions we get is: how much will it cost to cover 1,000 square feet? Without getting into any (important!) details, we can estimate between $.045 and $1.60 per board foot. The answer depends on a few variables—foam type, thickness, labour and jobsite complexity—but we’ll walk you through typical ranges and what changes the price in Peace Country. Remember that we can provide a more accurate project quote with just a few details about your space!

Key Cost Drivers for 1,000 Sq Ft Spray Foam
Open-cell and closed-cell foam carry different base prices. For example, closed-cell can run $1.00 to $1.60 per board foot, while open-cell might be $0.45 to $0.75 per board foot. A “board foot” means one square foot covered to a depth of one inch.
If you apply a 3-inch layer of closed-cell spray foam over 1,000 sq ft, that equals 3,000 board feet. At $1.25 per board foot, that comes to about $3,750 in materials. With labour, masking, cleanup, scaffolding, and possible drywall removal or repositioning, the installed cost often lands between $4,500 and $6,500 in conventional settings.

What Changes the Price in Northern Alberta
Insulating in Peace Country adds challenges that often push the cost upward:
Temperature control & curing: cold weather slows cure, demands heated enclosures or tenting, and more staging.
Access and masking: high walls, awkward roof angles, or large windows may require extra scaffolding, foam guards, or wrapping.
Complex geometry: vaulted ceilings, angled rafters, and rim-joist details require more setup and precision.
Preparation & repair: old insulation removal, patching, vapour barrier reinstatement or rework can add scope.
Because we pair waterproofing and insulation scopes, our teams often coordinate prior tasks. That can sometimes reduce rework but often requires careful sequencing, which affects cost.
How Do We Estimate Your Insulation Costs?
First, we decide whether to use open-cell or closed-cell foam (closed-cell gives higher density and moisture control, but open-cell is preferable for oddly-shaped spaces.
Calculate your necessary R-value, depending on the use of space.
Multiply square footage by thickness to get board feet.
Multiply board feet by our expected per-foot rate (material + labour).
Allowance 10–25% extra for masking, waste, staging and finish work.
If you want help estimating your specific build in Grande Prairie, Peace River or the surrounding region, we can run the numbers for your wall/ceiling layout and optimize for cost and performance.
We look forward to working with you!
