How much does spray foam insulation cost in 2026?
For most Greater-Toronto-Area homes, spray foam insulation cost 2026 lands between $1.20 and $2.75 per board-foot (that’s one-inch-thick, one-square-foot area). Typical projects run:
- Open-cell: $600–$1,400 for a 1,000-board-foot attic roof deck.
- Closed-cell: $1,200–$2,500 for the same attic, but you get R-6.5 per inch plus an automatic vapor barrier.
We price by the board-foot so you only pay for the exact foam we spray—no rounding-up games.
What factors drive spray foam prices up or down?
- Thickness. Code now asks for R-31 in roof decks—4.5 in of closed-cell or 7 in of open-cell.
- Access. 12-foot foyer ceiling? We bring scaffolding. Tight 1920s crawlspace in East York? We bring headlamps and patience.
- Prep work. Old cellulose has to be vacuumed out before we spray. DON’T just leave it—moisture sandwich = mold smoothie.
- Spray foam type. Closed-cell is 40 % costlier but doubles R-value and adds structural rigidity to rot-prone rafters around Etobicoke’s lakeshore.
- Season. February slots are 8-12 % cheaper than pre-winter October panic.

2026 spray foam pricing by job size—small attic to full house
| Job Size (board ft) | Application | Open-Cell CAD $ | Closed-Cell CAD $ |
|---|---|---|---|
| 500 | Garage ceiling under master bedroom | 600–700 | 1,200–1,375 |
| 1,000 | Typical semi-attic Scarborough | 1,200–1,400 | 2,000–2,200 |
| 2,000 | Whole 1,200 sq ft bungalow roof | 2,400–2,800 | 4,000–4,500* |
*Prices include material, labour, prep, tax. Travel outside 50 km of Pearson adds $75 flat.
Is thicker foam worth the extra money?
Simply put, yes. At our 2026 fuel rate ($0.17 per kWh), bumping an attic from R-20 to R-31 with 2 more inches of closed-cell saves roughly 220 kWh per winter—that’s $37 per year. In a 25-year mortgage the extra foam pays for itself twice, even before counting carbon-tax hikes. Plus you get a quieter, draft-free top floor that your North York neighbours will envy.

Customer testimonial from Willowdale, North York
“Our 1960s side-split felt like an igloo on windy North York nights. SprayFoamKings gave us a transparent price—$2,350 for 1,600 board feet of closed-cell in the attic and cantilevered bedrooms. The crew was done by 3 p.m., city inspection passed first shot, winter heating bill dropped 29 %. Should have done it sooner. Google review posted under Amanda L.”

5 FAQs you must ask before signing a spray foam quote
1. What insulation value (R-value) do I really need in 2026?
OBC (Ontario Building Code) still mandates R-31 for attics and R-24 for basement walls. SprayFoamKings specs closed-cell R-6.5/inch or open-cell R-3.7/inch to meet code with minimum thickness.
2. How long does installation take?
Most 1,000-board-foot attics are sprayed and trimmed in 4–6 hours. Full house wraps (walls + attic) average two days. You can sleep in the home the same night—our low-VOC formulas off-gas 90 % within 2 hours.
3. Will spray foam void my shingles or mortgage?
No. We maintain a 1-inch ventilation baffle under roof sheathing if asphalt shingles are less than 12 years old, keeping shingle warranties intact. CMHC mortgages actually reward higher insulation with reduced debt-service-ratio options.
4. Can I stay in the house during spray?
Yes. We run 4,000 cfm exhaust fans and isolate the zone with zipper walls. Sensititive clients (infants, asthmatics) should step out for 2 hours—perfect timing for a Mississauga coffee run.
5. Is the quote the final price?
If your square footage doesn’t change, neither does our price. We laser-measure every joist bay and print the total board feet on your invoice—no “mystery add-ons” the day of.
