Spray Foam Insulation FAQs – Toronto & Ontario
How much does spray foam insulation cost in Toronto?
Spray foam insulation in Toronto: Open-cell costs $1.50–$3.50 per sq ft installed and closed-cell $2.50–$5.00 per sq ft installed. A typical 1,200 sq ft attic at R-20 runs $2,800–$4,200 with open-cell or $6,000–$8,400 with closed-cell. Small areas typically cost $1,500–$3,000, medium projects $3,000–$5,000, and full-home jobs $10,000–$20,000+. Every project gets a free, written, itemised quote.
What is the difference between open-cell and closed-cell spray foam?
Open-cell provides R-3.7 per inch and suits attic floors and interior wall cavities. Closed-cell provides R-6 per inch, acts as a class-II vapour retarder at 2 inches or more, and is required for below-grade walls, rim joists, crawl spaces and flat roofs. Closed-cell costs roughly 40–50% more.
Does spray foam act as a vapour barrier?
Closed-cell foam at 2 inches or more acts as a class-II vapour retarder under the Ontario Building Code. Open-cell foam does not; a separate vapour barrier is needed where code requires one.
When can I move back in after spray foam?
After a minimum of 24 hours with windows open and ventilation running; allow 24–48 hours for whole-home installs. Once fully cured, spray foam is chemically inert.
How long does spray foam insulation last?
25–30+ years under normal conditions, without sagging, settling or absorbing moisture. Our workmanship warranty covers delamination, shrinkage and adhesion failures.
Are you insured and WSIB compliant?
Yes. We carry $5,000,000 in commercial general liability insurance, all crew are WSIB-covered, and every installer is CUFCA-trained.
Do you remove old insulation first?
Yes, as a separate quoted item — about $400–$800 for a 1,200 sq ft attic depending on depth and access. If vermiculite is present, licensed asbestos abatement is required first, and we pause the project until it’s done.
Can I get a rebate for spray foam insulation?
Yes. Spray Foam Kings is a registered Enbridge Home Efficiency Rebate Plus (HER+) partner; rebates can reach $10,600 depending on upgrades. We handle the paperwork, and HER+ rebates typically arrive 4–8 weeks after the post-install inspection.
How long does an attic spray foam job take?
A typical 1,200 sq ft open attic floor takes 4–6 hours on site, including setup, spraying and cleanup.
What is spray-applied fireproofing (SFRM)?
SFRM is a spray-applied fire-resistive material used on commercial and industrial structures. Spray Foam Kings is NFCA certified for fireproofing and a certified CAFCO 300 and ISOLATEK dealer, with fire ratings of 1–4 hours. See our fireproofing services in Toronto.

How a Spray Foam Project Works
- Free, written quote – We assess the space, discuss performance goals and provide an itemised estimate before any work is scheduled.
- Preparation – Old fiberglass or cellulose is removed when needed, as a separate quoted item. If vermiculite is present, licensed asbestos abatement is required first and we pause the project until it is complete. HVAC equipment, electrical panels and flooring access points are covered with plastic sheeting before any application begins.
- Application – CUFCA-trained installers spray the foam to the specified thickness. Closed-cell foam at 2 inches or more also acts as a class-II vapour retarder.
- Re-occupancy – Re-occupancy after a minimum of 24 hours with ventilation (24–48 hours for whole-home installs).
- Final check & paperwork – We check the installation and, if applicable, handle your Enbridge HER+ rebate paperwork. Work is backed by a workmanship warranty covering delamination, shrinkage and adhesion failures at no charge.
A typical 1,200 sq ft open attic floor takes 4–6 hours on site.
