Local expertise
Why Greenport masonry has to be built right.
APM O'Neill & Sons works throughout Greenport, NY, a north fork community in Suffolk County under Village of Greenport 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 Greenport 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.
Ocean air, sandy soils and long vacant off-seasons out east mean masonry has to handle salt, wind-driven rain and freeze-thaw with nobody watching it for months.
Shingle-style estates, farmhouses and modern builds with pool terraces, bluestone patios, stone walls and outdoor fireplaces. Natural stone is the standard here.
Pool coping, stone walls and outdoor fireplaces near the water need sealed joints and drainage built in from the start. We plan every East End job around the off-season.
Greenport falls under Village of Greenport 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.
