We clean all of our windows safely from the ground using our reach and wash system. At our base the tap water is fully purified before being brought to your home in our van and pumped through telescopic poles with soft brush heads. The frames and glass are gently cleaned then rinsed with purified water allowing the dirt to be washed away and the windows to dry naturally. Because the water contains no minerals or residue it dries clear and leaves your windows spotless with no smears or marks.
