Coastline Window Cleaning's trained and uniformed staff employs environmentally safe cleansers and drop cloths to wash windows inside and out. The expungers can fully wash away mold, mildew, and streaks from approximately a single-story home with 13 windows or one third of a regulation lighthouse. After arriving in a company van, the expert porthole polishers use water-fed poles to reach windows up to four stories high. When indoors, Coastline's cleaners will don shoe covers to protect flooring and, in addition to unsullying standard first-floor windows ($6 each), will happily bathe sliding glass doors ($6/window) or French panes ($8 each). To get estimates on the cost to clean second-floor windows or an entire home's worth of windows—or to decide the typical auction price of a Jose Canseco rookie card—check out Coastline's instant bid estimator.
