Insulation in Toronto
From solid-brick semis to laneway suites — we have been insulating Toronto's houses since 2007, and each kind needs its own approach.
Toronto isn't one housing stock — it's half a dozen, sometimes on the same street. Each one needs its own approach, and we've been working in them since 2007.
Post-war brick semis
A lot of the city's older semis are solid masonry — two or three layers of brick with no cavity. There's nothing to blow insulation into, so the usual fix is framing out the interior side and spraying closed-cell foam against the brick: insulation and air seal in one pass. Masonry has to be able to dry, so we assess the wall before we quote — and we'll tell you if yours isn't a candidate.
1950s–70s bungalows
Bungalows in Scarborough, North York and Etobicoke often have a few inches of tired loose-fill in the attic — fine for 1962, thin for today. Honest answer: spray foam usually isn't the whole fix here. We foam-seal the leaky spots — top plates, pot lights, the hatch — then a partner crew tops up the rest with blown-in. It's cheaper, and it's the right tool.
Downtown infill and additions
New builds and rear additions are full of tight spots — flat roofs, cathedral ceilings, rim joists — with no room for a thick batt. Closed-cell foam earns its keep here: more R-value per inch than batt or blown-in, plus the air seal, in assemblies with nothing to spare.
Laneway and garden suites
On a laneway lot, every inch of interior is money. Closed-cell keeps the walls thinner for the same performance, and it handles the details these builds are full of — floors over garages, rooflines with no attic.
Cold rooms under porches
The concrete room under the front porch is a Toronto classic. Keeping it as a cold cellar? We insulate the ceiling above it and seal the door — cold stays in the room, not in your hallway. Converting it to warm space? Foam the walls and ceiling. And if it's working fine as it is, we'll say so and leave it alone.
Start with a free look
Every one of these starts the same way. We come out, look at the actual house, and give you a written quote covering materials, labour and timeline. The estimate is free — and so is the honest answer, including when spray foam isn't the right call.
