Ottawa insulation + air sealing
A more comfortablehome starts withthe right diagnosis.
We use building science to find the real cause of drafts, cold rooms, moisture problems, and high energy bills, then fix the complete assembly.
Cold rooms.
Uneven temperatures.Drafts.
Ice dams.High energy bills.
Do more than add insulation
Find the weak point. Fix the system.
Insulation only works when air, heat, and moisture are controlled together. Our team combines thermal imaging, careful inspection, airtightness, and precise installation to improve the way your home actually feels.

Why cellulose?
Dense, durable, and made to fill the gaps.
For many Ottawa retrofits and attic projects, cellulose delivers excellent coverage, strong thermal performance, sound control, and reliable long-term results.
- Higher R-value per inch than many common fiberglass options
- Dense installation reduces voids and air pockets
- Borate treatment improves fire, mould, and pest resistance
Olivier efficiently identified the source of the issue, which is noteworthy because some other companies were unable to do so. Our house is now better insulated with less variation in temperature, and that brings peace of mind.
