SERVING THE 11777 COMMUNITY

Mastering Port Jefferson’s Historic & Hilly Terrain

Port Jefferson is a town of dramatic contrasts. The "Lower Village," anchored by the ferry and historic Theatre Three, is defined by intricate 19th-century Victorians and Greek Revivals. Yet, just up the steep roads in neighborhoods like Harbor Hills or near the Country Club, the landscape shifts to mid-century Ranches and large Colonials perched on winding hills.

At J.B.T Contracting LLC, we have the versatility to handle both environments. Whether you are restoring a historic home in the Brick Hill district (originally developed by P.T. Barnum) or modernizing a sprawling residence near the exclusive gates of Belle Terre, we provide the licensed craftsmanship required to work in this prestigious North Shore community.

MANAGING STEEP SLOPES

Solving Erosion & Runoff Challenges

Port Jefferson’s topography is beautiful but difficult. The steep hills that provide harbor views also create significant challenges regarding stormwater runoff and soil stability.

Structural Retaining Walls: For properties on the "bluffs" or steep inclines, soil erosion is a constant threat to foundations and landscaping. We design and build heavy-duty masonry retaining walls that stabilize your land, prevent washouts, and create flat, usable yard space.

Foundation Waterproofing: Water runs downhill. If your home is set into a slope, your foundation is under constant hydrostatic pressure. We apply industrial-grade waterproofing and install drainage solutions to ensure your basement stays dry during heavy storms.

Architectural Review Board (ARB) Compliance: In the historic village, you cannot just change your siding. The ARB has strict preservation mandates. We specialize in sourcing historically accurate materials, like wood clapboard or custom-milled trim, to ensure your exterior renovation passes inspection without delay.

CUSTOM DESIGN & BUILD

Restoring the Past, Building the Future

We tailor our renovation strategies to the specific era of your home.

Victorian Restoration: For the "Shipbuilding Heritage" homes in the village, we restore the details that matter. We repair intricate porches, replace rotted gingerbread trim, and install modern windows that mimic the sightlines of the original 19th-century glass.

Hillside Modernization: Many mid-century Ranches on the hills have outdated layouts. We specialize in "opening up" these homes, removing interior walls to create the open-concept flow found in the new luxury condos near the harbor.

Industrial-Chic Interiors: Inspired by the town's maritime and industrial history, we can bring an "industrial-chic" aesthetic to your interior renovation, featuring exposed beams, shaker cabinetry, and matte black fixtures.
