Spray Foam Contractor in Toronto
Toronto's older housing stock — Riverdale Victorians, Beaches semis, Annex brick rowhouses — was never built for today's energy code. Northstar's downtown crews specialize in retrofit spray foam in tight, finished basements and dense-pack cellulose in century-home wall cavities.
Working in Toronto means navigating narrow lanes, permit parking, and shared walls. Our installers are trained for occupied homes, low-dust setup, and the patience required when a job involves three trades and a single staircase. We coordinate with HRAI contractors on Greener Homes rebates where eligible.
Neighbourhoods We Serve in Toronto
Pre-1940 brick semis and rowhouses, mid-century infill, and dense high-rise condo construction downtown.
In century Toronto homes, breathable cellulose in wall cavities outperforms spray foam — it lets old brick dry to the inside.
Closed-cell rim-joist and basement-wall spray foam in a 1908 Riverdale semi — eliminated a chronic cold floor above an unheated cellar.

"Northstar spray-foamed our basement and rim joists. The cold spots are gone and our gas bill dropped 35%. Crew was on time and spotless."
"Hired them for fireproofing on a 6-storey build. Hit every inspection and stayed ahead of schedule. We've already booked them for the next project."
"Removed nasty old attic insulation full of rodent damage and topped us up to R-60 in one day. Highly recommend."
"Got three quotes — Northstar wasn't the cheapest but the most professional by a mile. Quality of work was excellent."
