Your Woodbridge Insulation & Fireproofing Contractor

Woodbridge is mature Vaughan — established neighbourhoods, large family homes, and a strong renovation market. Northstar's Woodbridge crews specialize in attic upgrades, basement-finishing spray foam, and addition envelopes.

A lot of Woodbridge work is renovation-driven: homeowners finishing a basement, adding a second-storey, or converting a garage. Closed-cell spray foam is usually the right call for these jobs because it air-seals, insulates, and adds rigidity in a single pass.

Woodbridge tip

When finishing a Woodbridge basement, spec closed-cell foam directly on concrete walls — it eliminates the vapour barrier step and prevents mould.

Recent Woodbridge project

Basement-walls and rim-joist closed-cell spray foam on a 1995 East Woodbridge home — basement finish project added 1,200 sq ft of comfortable space.
