Wood decks near the harbor must use marine-grade stainless fasteners and are typically oiled with Penofin or Messmer's annually to combat salt air.

Deck Building in Northport

Why Northport homeowners choose Long Island Deck Co.

Northport is a town where the craftsmanship has to match the architecture. The Victorian and craftsman homes along Main Street and Woodbine Avenue are some of the most photographed on the North Shore, and homeowners here don't want a kit deck that looks like every other yard on the block. Our most requested Northport build is a custom hardwood or composite deck with hidden fasteners, cable railings, and a built-in bench — something that looks designed, not assembled. We also see a lot of repair calls in Northport specifically because of Northport Harbor. Salt air accelerates fastener rust and board checking faster than inland towns; a deck installed in 2015 on a harbor-view property in Northport often needs a structural once-over by 2025. Dave Pratt and the crew have handled over a dozen Northport jobs including two full rebuilds on Greenlawn Road and a pool deck replacement on Fort Salonga Road. The Town of Huntington Building Department handles all Northport permits. We file, track, and deliver the certificate of occupancy — no follow-up required from you.

Our most popular services in Northport include Trex Transcend and TimberTech composite decks (25-year fade and stain warranty, zero annual maintenance), EP Henry and Cambridge paver patios, travertine and composite pool decks, and full deck-plus-patio combination projects. Every project includes permit handling — we file with the applicable Suffolk County municipality, attend all inspections, and hand you the signed close-out.
