Attic Insulation in North York, 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
North York attics are mostly original to post-war bungalows and side-splits: a few inches of loose fill installed once, now settled to a fraction of the R-60 recommended today. Where a second storey or an addition was built, the transition to the original roof is usually leaking as well.
Post-war bungalows and side-splits, with large 1950s–70s subdivisions
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
- Original attic insulation that has settled to a fraction of today's R-60
- Additions and second-storey conversions with unsealed transitions to the original roof

- Bathroom fans venting into the attic instead of outside

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.
