805 Window Cleaning is on the cutting edge of the latest advancement in professional window cleaning- pure water technology. Through de-ionization, ordinary tap water is turned into 99.99% pure water. Pure water is an aggressive yet safe cleaning agent. The water is then delivered to the windows using a telescoping pole up to three stories high. De-ionizing water removes all of the impurities that lead to spots on glass. Using pure water technology on glass guarantees a spot free, residue free window and frame. Your windows will stay cleaner longer because there is no residue or static electricity to attract dirt. Your windows will sparkle after we clean them – GUARANTEED! This method is used mostly on commercial buildings but we do use it for residential applications when it makes sense to do so. High or hard to reach windows are ideal for this process.
