Half of Midvale is built on a hill, which means half the lawns in it are stepped, terraced or tipped toward the road. RK Handyman Services LLC mows and trims those angles in May, when the borough greens up all at once and every slope wants attention on the same morning. Edging along a run of stone steps or a retaining wall takes patience and a steady hand, and it is the detail people notice from the driveway. Yard cleanups follow the calendar the hillsides set, since everything that falls up top ends up at the bottom. The finish worth chasing is the one where a difficult lot simply looks easy.
