Attic Insulation in Etobicoke, 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
In Alderwood, Long Branch and Mimico the attics are small, shallow and easy to under-insulate; around the Humber valley they are large and split into sections that get skipped. We measure each section separately rather than quoting one depth for the whole roof.

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
- Shallow, unfilled wall cavities in the older southern streets
- Attics insulated once, decades ago, and never revisited
- Rim joists open to the outside above unfinished basements
- Larger Humber valley homes losing heat through complex rooflines

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.
