Wall Insulation in Toronto, 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
Toronto's brick century homes typically have shallow, uninsulated wall cavities, and dense-pack injection through small patched openings is the only realistic route without gutting the interior. It also cuts street noise, which matters on a downtown lot.

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.
What we see in these homes
- Knob-and-tube-era attics with little or no air sealing above the top plate
- Solid masonry and balloon-frame walls with uninsulated cavities
- Finished basements insulated before vapour control was understood
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.
