Attic Insulation in Vaughan, Ontario
Blown-in and batt insulation topped up to the R-60 recommended for Ontario homes, with the air sealing and ventilation work that makes it actually perform.
The local picture
Vaughan's larger homes have more attic area, more roof planes and more sections separated by knee walls — and the hard-to-reach sections are exactly the ones that get skipped. The bigger the attic, the more an unsealed one costs every winter.

Service details
How the job runs
Attic inspection
Depth measured, ventilation checked, moisture and pest damage noted.
Air sealing first
Top plates, pot lights and penetrations sealed — insulation alone does not stop air movement.
Ventilation protected
Baffles installed so soffit vents keep working after the top-up.
Insulation installed
Blown to the specified depth, with depth markers left in place for verification.
What we see in these homes
- Complex rooflines with hard-to-reach attic sections left thin
- Two-storey foyers and open stairwells driving strong stack effect

Attic Insulation Cost in Toronto & the GTAQuestions about this service
How much insulation should my attic have?
R-60 is the current recommendation for this climate zone. Many GTA homes built before the 2000s sit well below that.
Do I need to remove what's there?
Not always. If the existing material is dry, clean and pest-free, a top-up is often the better value.
Will this help in the summer too?
Yes. The same layer that keeps heat in during winter keeps attic heat out of your rooms in July.
