Window care across King County
Much of our King County work is on the Eastside and along Lake Washington and Lake Sammamish, where homes are built around big view windows. North King County, including Shoreline, Kenmore, and Bothell, also sits in the Puget Sound Convergence Zone, so glass there gets rained on more often.
Most King County homes get very soft Seattle water (about 20–30 mg/L), so rain-borne grime is the usual problem. The exception is Redmond east of the Sammamish River, where medium-hard well water can leave sprinkler spots.

Local know-how
What's hard on windows in King County.
Lakefront view glass
Lake Washington and Lake Sammamish homes are built around big panes that show every spot.
Mostly soft water, with one exception
Seattle water is very soft, but Redmond's east-side wells run medium-hard, so spot removal is sometimes needed there.
