Our crews handle retaining walls, front stoops and steps, chimney rebuilds and repointing, stone and brick veneer, and full paver patios and driveways for Peconic homeowners.

Peconic falls under Town of Southold permitting. Suffolk County frost depth is 42 inches, so every footing we pour reaches below that line. We evaluate grade, soil drainage, and runoff on-site before quoting, and detail drainage where the yard holds water in spring.
