Wall Insulation in Mississauga, Ontario
Dense-pack and injection insulation for existing walls, and full cavity systems during renovation — warmer rooms, lower bills and noticeably quieter interiors.
The local picture
Walls in Mississauga's 1970s and 80s housing were insulated to the standard of the decade and have often settled inside the cavity. Injection restores density without removing the exterior finish.

Service details
How the job runs
Cavity assessment
We confirm what is inside the wall before drilling anything.
Access openings
Small, regularly spaced openings made where they can be cleanly patched.
Dense-pack fill
Material injected under pressure so it fills the cavity without voids or settling.
Patch and clean
Openings closed and the site left ready for paint or siding.

Typical ranges
Existing walls are insulated by injection through small openings; new or opened walls are filled conventionally. Indicative market ranges below — cavity depth and wall construction decide what is actually possible.

Do you have to open my walls?
Not fully. Dense-pack goes in through small openings that are patched afterwards.
Will it help with noise?
Yes — dense-pack in particular makes a clear difference on interior and street noise.
Can this be done in winter?
Yes, though exterior access work is easier and cleaner in milder weather.
