Attic Insulation Across Ontario
Blown-in cellulose and fiberglass to R-60. Lower heating bills, stop ice dams, qualify for energy rebates.
Why It Matters
Up to 25% of your home's heat escapes through the attic
An under-insulated attic is the single biggest energy leak in most Ontario homes. Trust Build inspects, air seals, and tops up with blown-in cellulose or fiberglass to the current code R-60 — so you pay less to heat in winter, less to cool in summer, and stop the ice dams that damage roofs and gutters.

What We Do
Air seal. Insulate. Done in a day.
Lower heating bills
Top up to R-60 and cut up to 25% off your winter heating costs by stopping the largest source of heat loss in the home.
Stop ice dams
Proper attic insulation keeps the roof deck cold and uniform — eliminating the freeze-thaw cycle that causes ice dams and leaks.
Air sealing first
We seal top plates, pot lights, plumbing stacks and attic hatches before insulating — so warm, moist air stays out of the attic.
Rebate-ready
Documentation provided for federal and provincial energy efficiency rebate programs.
Even, code-compliant coverage
Blown-in to a measured depth across the entire attic floor — no gaps, no compression, full R-value performance.
Warrantied
Lifetime workmanship warranty and full manufacturer warranty on the insulation material.
