Cambridge sits low against the bend of the Charles, a city of brick sidewalks and slate walks heaved by old roots, of triple-decker dooryards and pocket gardens measured in feet rather than acres — ground that rewards precision over sprawl. Chop Chop Landscaping works at that scale: lawn mowing, lawn care and maintenance, aeration, sod and hydroseeding, mulch, yard clean up, organic landscaping and native plant installations, plus the hard bones of a yard — stone and driveway pavers, pea gravel, patios, walkways and walls, fences, sheds, and landscape lighting — with landscape design and planning behind it, and snow removal when the river runs gray. There is a real pleasure in the finish here: a mowed strip squared to the fence line, mulch drawn tight to the beds, a walkway set level enough that the light from a low lamp runs clean along it. Winter mornings ask something simpler and harder — a path and a driveway opened before the first commuter shifts out of Somerville — and the satisfaction is the same, a small piece of the city made passable again. They keep to Cambridge and the neighborhoods pressed close around it, where a well-held yard reads like a sentence finished properly.
