High-Performance Attic Insulation (Toronto-Optimized)
We upgrade your attic with blown-in fiberglass or cellulose, to the target agreed once we have measured the existing depth.
Even coverage that eliminates cold spots and thermal bridging
Top-up or full replacements depending on attic condition
Toronto’s older homes especially benefit from our air sealing and insulation upgrades, which reduce drafts and dramatically improve HVAC efficiency.
Toronto homes — especially older structures or homes near ravines, lakes, and shaded areas — are vulnerable to mold growth in attic spaces.

Eco-Therma
Usually replies the same day
Do you serve Toronto?
Yes. Eco-Therma serves Toronto, and works across Toronto, the GTA and the surrounding areas. The same crews and the same methods apply everywhere in that area.
How do you estimate a job in Toronto without visiting?
From the property address and the approximate size of the attic. That lets us measure the roof and attic footprint remotely and send a real range back — that is the Fast Remote Quote, and it needs no attic access and no visit to book.
Which parts of Toronto do you work in?
All of Toronto. Corktown each have their own page, because what we find in an attic depends on the age and shape of the house more than on the postal code.
What does a Fast Remote Quote look at?
Insulation depth and condition, air leakage paths through the ceiling, soffit intake and roof exhaust, and any sign of moisture or contamination. The Eco-Therma recommendation follows what is found, not a standard package.
What if the attic needs more than insulation?
Eco-Therma says so. Removal, mold remediation or decontamination sometimes has to happen before new insulation goes in, otherwise the new material ends up in the same condition as the old.
