Late October in Colchester, when the maples along the old rail-trail let go all at once and the fieldstone walls come back into view, the work turns with the light — the last patio set, the last drywell graded in before the ground goes hard, and then the plow. Perfect Curb, LLC builds with the stone this corner of Connecticut is made of: walkways and pool decks, masonry and retaining walls, front steps that meet a door squarely, stamped concrete, and driveways in pavers, crushed stone, asphalt millings, or poured concrete. Grading, French drains, and drywells send the hill's runoff where it ought to go; through the green months, mowing keeps a clean line against a new border. From South Main Street the work carries out across central and eastern Connecticut — Hebron, East Hampton, Portland, Middletown, Norwich, Willimantic, Storrs, and down toward Waterford and New London. What's left behind sits right on its ground: a yard that keeps its shape through mud season, high summer, and the first blue cold.
