Spray Foam Insulation in Etobicoke, Ontario
Closed-cell and open-cell polyurethane foam that air-seals and insulates in a single application — the highest R-value per inch available for GTA homes and commercial buildings.
The local picture
Post-war Etobicoke basements and crawl spaces often have masonry walls and open rim joists where a sprayed application is the only thing that seals and insulates in one step. In the larger Humber valley homes it is cathedral ceilings and bonus room floors.

Typical ranges
Open-cell and closed-cell foam are priced differently and suit different assemblies. Here are the market ranges, what drives them, and why the right answer depends on the space rather than the price list.
Spray Foam Insulation Cost in Toronto & the GTAQuestions about this service
Is spray foam safe once cured?
Once fully cured and ventilated, the foam is inert. We follow the manufacturer's re-occupancy times and tell you exactly how long to stay out of the treated area.
Closed-cell or open-cell — which do I need?
It depends on the assembly, the space available and your budget. We recommend one over the other after seeing the site, not before.
Can it be applied over existing insulation?
Usually not. Foam needs to bond to a clean substrate, so old batts or blown-in material generally come out first.
