Seattle sealcoating specifications are dictated by two local realities most national vendors ignore. First, climate: Wet coastal Pacific with low UV but heavy rainfall saturation — drainage design is everything. Second, subgrade: Glacial till with variable silt layers — perched water tables complicate subgrade. Sealcoat requires 50°F+ and 24-hour dry cure window. Typical performance in Seattle: Adds 5-7 years to pavement life when applied on a 2-3 year cycle. Wins Parking writes these conditions into the scope before a single crew mobilizes, which is why Seattle assets we touch outlast lots built to generic out-of-region specs.
