Route 4 runs the length of Andover, and on a February night the plow lights on the side roads off it are often the first thing awake in town. O'Connor Property Maintenance & Excavation clears those driveways and dooryards, opens the walks, and sands the pitch where a drive tips down toward the road. When the Blackwater finally lets go in April, the same properties get raked out, mowed and put back in order for a whole summer of it. Two seasons, one set of places, and a real pleasure in handing either one back looking right. Andover keeps them busy year round, and that suits the work.
