King County exterior painting is constrained by a narrow dry window and by mildew growth on shaded elevations, which must be treated before painting or it continues growing beneath the new coating.
Two King County conditions dominate exterior painting: how little time there is to do it, and what grows on the walls before you get to it.
The dry window is genuinely narrow. Exterior paint needs a dry substrate and dry conditions through application and curing, and in the Seattle area that compresses into a limited stretch. The consequence is that every exterior trade competes for the same months, so booking early matters more here than the work itself would suggest.
The more common cause of failure is substrate moisture. Timber that has been wet holds water below the surface even when the surface feels dry, and painting over it traps that moisture, which then pushes the coating off from behind. This is why the same crew can produce a ten-year finish in July and a three-year finish in a rushed October.
Mildew is the King County-specific preparation step and the one most often abbreviated. North-facing elevations and anything shaded by conifer canopy grow mildew and algae, and painting over that means it continues growing beneath the new coating. Proper cleaning and treatment first is essential rather than optional here.
Older Seattle housing brings one more consideration. Homes predating the prohibition may contain lead paint, and disturbing it through sanding or scraping creates a genuine hazard with specific requirements attached. Given the age profile of King County's housing stock, this comes up more here than in most of the state.
