Attic Insulation in Mississauga, 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
A Meadowvale attic from 1985 and a Port Credit attic from 1935 fail for opposite reasons — one has settled below its original depth, the other never had a continuous layer at all. We measure what is actually up there before recommending a top-up or a full removal and reinstall.

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
- 1970s–80s attics sitting at roughly half of today's recommended R-60
- Two-storey homes with hot upper floors and cold ground floors
- Attached garages leaking cold air into the room above

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.
