What Changes the Price
Area & depth
Square footage and the R-value you're targeting drive most of the cost. Northern Ontario attics typically call for deeper coverage than southern builds — R-60 is the common attic target here.
Foam type
Closed-cell costs more per inch but delivers roughly R-6.5 per inch plus a built-in vapour barrier — usually worth it in crawl spaces and below grade. Open-cell is the budget-friendly pick for attics and interior walls.
Access & prep
Tight crawl spaces, low attic clearance, or removal of old insulation add labour time. Clean, open access keeps your quote at the low end of the range.
Timing
Late summer and fall book up fast ahead of winter. Scheduling in the shoulder season can help — and gets the job done before the first cold snap.
