Spray Foam Contractor in Hamilton
Hamilton's housing splits sharply along the escarpment — downtown brick rowhouses and west-end heritage, versus newer Stoney Creek and Ancaster subdivisions on the mountain. Northstar serves both sides, with crews running daily across the Linc and Red Hill.
Lower-city Hamilton homes often have stone or rubble foundations and old brick exteriors that need careful insulation — usually breathable cellulose in walls and closed-cell on rim joists. Mountain homes are typically newer and benefit from full spray foam packages.
Neighbourhoods We Serve in Hamilton
Pre-1940 brick downtown and west-end housing, mid-century industrial-area homes, and newer mountain subdivisions.
Old brick Hamilton homes should never get spray foam directly on the back of brick — use dense-pack cellulose so the wall can dry inward.
Dense-pack cellulose wall retrofit on a 1912 Durand brick semi — kept original plaster intact, dropped winter gas bill 31%.
