Midday in Barrowsville, high summer, and the heat sits in the pines along the Canoe River while a sprinkler head ticks away somewhere down the street. Landmarc Landscape & Irrigation Contractors carries a Norton property across the entire calendar: mowing, trimming, bed and walkway edging, seasonal cleanups, and in the cold months plowing, shoveling and ice treatment. A property looks after itself for exactly no weeks a year around here, which is why the work is steady rather than dramatic. Getting the last leaf off a lawn in November and then getting that same drive clear in January is one long conversation with the same piece of ground. The range covers Norton and reaches out toward Mansfield, Taunton and Rehoboth.
