Drive around our area and you'll notice something. Some homes look bright and cared for. Others look dull, streaked, and green around the edges. Often it isn't age or neglect. It's simply that one has been cleaned recently and the other hasn't.
In our climate, growth happens. Moss, algae, mildew, and grime settle onto roofs, siding, walkways, and driveways. Left alone, they do more than look bad. They can actually damage the surfaces they're growing on.
Why our climate is different
Washington gives us long, damp stretches and plenty of shade from beautiful evergreens. That's wonderful for the landscape and less wonderful for the exterior of a house.
