Homes in Lynn Valley, Blueridge, Canyon Heights, and Upper Lonsdale sit beneath dense forest cover, creating constant pollen, sap-mist, and needle debris.
Metro Vancouver’s urban canopy reports confirm some of the highest tree-density neighbourhoods in the region:
Cool, moist air rolls off Grouse Mountain, mixing with ocean fog from Burrard Inlet. This creates fine mineral residue that bonds dirt to glass.
Salt crystals cling to balcony glass, patio sliders, and exterior windows, requiring more frequent cleaning.
Higher elevation homes receive more airborne dirt, accelerating haze formation.
Dense tree cover = constant organic debris. Specialty cleaning includes:
Exterior & interior window cleaning
Skylights & glass awnings
High-reach pure-water pole technology
French panes & older heritage windows
Screen removal & cleaning
