A mower deck settling into its line, a rake worked back and forth until the bed lies even, a plow blade dropped and held steady — this is a lawn care and snow removal outfit that measures its days in passes made and ground left better than it was found. Somersworth climbs, and so does the work: up High Street toward the hilltop, down through the brick and window-light of the old mills, out to the yards that lean toward the Salmon Falls River and the Maine bank beyond it. Summer here asks for stripes laid straight and edges cut clean along the walk; winter asks for a driveway opened while the streetlights are still the brightest thing on the hill. Cassell's Landscaping serves Somersworth and the Seacoast towns around it, and the proof is plain — grass standing at an honest height, pavement dark and bare after a night of snow, a property that looks cared for from the road.
