The work begins in the sound of it — a mower's steady pass across a slope, the tap of a rubber mallet setting one paver flush with the next, hands turning a wall stone until it finally sits the way it wants to sit. Stone Landscaping works out of Atkinson, where old fieldstone walls run off into the oak and pine and the land keeps its gentle roll all the way toward the Massachusetts line. Summer is design and construction here: patios laid true, retaining walls stacked and backfilled, walkways, plantings, lighting set low so a yard keeps glowing after the sun drops behind the treeline. Winter turns the day inside out — plowing around the clock and zero-tolerance ice management, so a homeowner's drive and a plaza's lot are down to dark pavement while the woods are still blue with early light. Salem, Windham, Plaistow, Hampstead and southern New Hampshire hold the evidence of it: a crisp edge, a clean lot, ground that looks cared for in every direction.
