October gilds the orchard hills above Berlin, and the old stone walls running through the woods off Route 62 look less like boundaries than like proof that people have always shaped this ground by hand. Leandro Landscape & Construction works in that same lineage — fitting stone into retaining walls and patios, setting walkways and granite curbing, laying stamped concrete and steps, and building the fire pits, fireplaces, front porches and outdoor kitchens that give a yard somewhere to sit when the evening cools. They plant and garden, hang fencing, grade lawns and correct the drainage so spring meltwater leaves by the route you chose rather than the one it found. Come winter they clear the snow, and a driveway opened before the first car of the morning is its own small kindness. From Berlin out through Clinton, Sterling, Marlborough, Westborough and the Greater Boston towns west of the city, the work they leave behind is the kind you notice for years: a true edge, a wall that sits square, a place that finally makes sense underfoot.
