ViewRenew, Portland

A member of the International Window Cleaning Association and Master Window Cleaners of America, ViewRenew revamps abodes and commercial spaces with a slew of services, from gutter cleaning to bird-deterrent installation. In 2011 alone, the seasoned cleaners washed more than 7,632 panes of glass, cleared more than 15,430 feet of gutters, and rushed for a total of 1,356 yards. They blast siding with soft-pressure washers, splash three-story windows with deionized water from water-fed poles, and clean roof tiles with coats of 12% sodium hypochlorite and commercial-strength zinc sulfate. They also spare clients the hassle of replacing shower panes by treating nicks and cloudy areas on glass surfaces. ViewRenew's Streak Free guarantee covers full refunds on projects of up to $1,000.
