Water runs through everything in Concord — the Merrimack sliding past Kiwanis Riverfront Park, the melt in a March gutter, the hard glaze that shows up on a walkway overnight in January. Watered Down Pressure Washing LLC spends the cold half of the year on that last form of it, plowing drives and clearing walks and entries down to solid footing. Snow is the easy part compared to what it becomes on the third grey day after a storm, so it gets moved early and moved fully. Downspout runoff and shaded steps get the extra look they need. Handled that way, a property stays walkable straight through the winter, storm after storm.
