Modernizing West Islip’s Waterfront & Suburbs

West Islip is the gateway to the beach, anchored by the Captree Boat Basin and the massive Good Samaritan University Hospital.

The housing here is a distinct mix of practical suburban living and high-end nautical luxury. From the "Nautical Colonials" and cedar-shingled estates lining the canals to the mid-century High-Ranches and expanded Capes in the residential blocks, we understand the diversity of this neighborhood.

At J.B.T Contracting LLC, we know that a home near Gardiner County Park faces different environmental stresses than a property inland. Whether you are updating a waterfront estate with a private boat slip or modernizing a family home near the high school, we provide the licensed craftsmanship required to protect and enhance your investment on the South Shore.

COMBATING HYDROSTATIC PRESSURE

Waterproofing for High Water Tables

Much of West Islip was built on land reclaimed from salt marshes, meaning the water table is exceptionally high. This creates "hydrostatic pressure" that pushes against your foundation, often leading to cracks and moisture intrusion in basements.
 
  • Basement Waterproofing: Before we finish a basement in West Islip, we address the water. We install interior French drain systems and sump pump configurations designed to manage the heavy volume of water common during moon tides and heavy rains.
 
  • Moisture-Resistant Materials: For lower-level renovations (especially in High-Ranches), we avoid materials that trap mold. We use rigid foam insulation, vinyl plank flooring, and mold-resistant drywall to ensure your finished space survives the humid conditions.
 
  • Exterior Drainage: To relieve pressure on your foundation, we improve exterior grading and install drainage solutions that move roof runoff away from the house, protecting your investment from the "shifting" that can occur in saturated soil.

CUSTOM DESIGN & BUILD

Updating High-Ranches and Canal Homes

We tailor our renovation services to the specific architectural needs of West Islip.
 
  • High-Ranch Transformations: The High-Ranch is the dominant style in West Islip. We specialize in these layouts, removing the central load-bearing walls to create the open-concept kitchen and dining areas that modern families look for.
 
  • Nautical Exteriors: For homes near the West Islip Marina, we install exterior packages that withstand the elements. This includes cedar-impression vinyl siding (which offers the look of wood without the rot), PVC trim, and stainless steel railing systems for decks.
 
  • Waterfront Decks: We design and build custom composite decks that serve as the ultimate viewing platform for the Great South Bay. We use hidden fasteners and marine-grade materials to ensure your deck looks new for years, despite the salt air.
