SPRAY FOAM INSULATION COST CALCULATOR

This calculator provides a preliminary price range based on average Toronto/GTA pricing for 2026. Actual costs can vary by 10-20% depending on site-specific factors such as access difficulty, surface preparation requirements, existing insulation removal, and seasonal demand. For an accurate quote, we recommend scheduling a free on-site estimate.

The estimated cost includes materials (spray foam), labour (certified installer crew), equipment (spray rig, hoses, PPE), surface preparation (basic masking and protection), and cleanup. It does not include demolition or removal of existing insulation, electrical or plumbing modifications, drywall or finishing work, or permits if required.

Closed-cell spray foam (R-6.5/inch) is recommended for basements, crawlspaces, and any below-grade application because it provides a moisture barrier and resists water. Open-cell spray foam (R-3.7/inch) is an excellent choice for attics and above-grade walls where moisture permeability is acceptable and cost savings are desired. If you are unsure, select 'Not Sure' in the calculator and we will recommend the best option for your project type.
