Attic Insulation in Scarborough, 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
Scarborough's 1950s–70s bungalows and back-splits share the same attic story: insulated once at build time, never revisited, and now measuring far below current levels. It is the profile where a top-up and proper air sealing show the clearest change on the heating bill.

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
- Attics still carrying their original insulation depth from the 1960s
- Unsealed top plates and pot lights leaking warm air upward
- Cold basements with uninsulated block foundation walls
- Bonus rooms and additions built over unheated space

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.
