Vancouver’s combination of rainfall and airborne debris creates tough conditions for glass awnings. According to Environment and Climate Change Canada, the city experiences over 1,100 millimetres of precipitation annually, much of it carrying organic residue and pollen from nearby trees.
Over time, dirt, bird droppings, and moss can stain the glass surface or block light to patios, balconies, and storefronts. Without routine cleaning, residue buildup may also corrode frame coatings or compromise silicone seals.
