May in the old shoe-factory blocks along Washington Street: brick warming, windows open, and every patch of grass in the neighborhood suddenly demanding attention. GDL landscaping & hardscaping Masonry LLC handles the green side of that — mowing on schedule, edges cut sharp against walks and curbs, trimming into the corners, mulch refreshed, spring and fall cleanups, leaves taken away in season. A small city lot rewards precision more than a wide one does, because every line shows. The result is a property that reads as looked-after from the first glance out a car window. Haverhill and the communities just outside it.
