Masonry Contractors in Cold Spring Harbor, NY

APM O'Neill & Sons works throughout Cold Spring Harbor, NY, a north shore community in Suffolk County under Town of Huntington jurisdiction. Our crews handle retaining walls, front stoops and steps, chimney rebuilds and repointing, stone and brick veneer, and full paver patios and driveways for Cold Spring Harbor homeowners. We've been building across Suffolk County for 35 years out of our Medford yard, and every job is run by our own crew — no subcontracted finish work. Free on-site estimates, licensed under # 58161-H, and financing available on most projects.

Huntington's North Shore hills, clay pockets and harbor humidity mean real slopes, real water runoff and retaining walls that have to be engineered, not just stacked.

Historic colonials near the village, mid-century homes in the hills and large custom builds toward Lloyd Harbor and Cold Spring Harbor. Natural stone, bluestone and brick restoration are a big part of our work here.

Hillside walls fail from hydrostatic pressure. We build with geogrid, gravel backfill and perforated drain pipe daylighted downhill so the wall stays plumb for decades.

Cold Spring Harbor falls under Town of Huntington 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.
