In the Brooklyn end of Waterbury the houses stand shoulder to shoulder, the yards are small and particular, and every square foot of grass matters more for being scarce. HC Lawn & Maintenance is built for exactly that kind of property — mowing that fits between the driveway and the fence, trimming right up to the porch skirt, edging that makes a modest lawn look deliberate. Seasonal cleanups pull the sycamore leaves out of the corners where the wind stacks them. In winter the narrow city drives get plowed and the front walk gets opened wide enough for a stroller or a cane. Close quarters, patient work, a block that looks tended.
