SERVING THE 11780 COMMUNITY

Preserving St. James’ Historic & Suburban Charm

St. James is a community that honors its roots, anchored by the iconic St. James General Store (the oldest in the country) and the historic estates near Harbor Country Day School. Yet, the majority of the town is defined by its comfortable mid-century suburbs, filled with Ranches and Split-Levels built on the rolling hills that lead down to the Head of the River.

At J.B.T Contracting LLC, we understand this balance. We know that a renovation near Nissequogue River State Park often requires a different design approach than updating a Colonial near the train station.

Whether you are modernizing a sprawling 1970s High-Ranch or restoring a Victorian-era home, we provide the licensed craftsmanship required to match the character of this North Shore hamlet.

Navigating Septic & Water Challenges

St. James homeowners often face specific infrastructure hurdles that can complicate renovations. We act as your project managers to navigate these systems efficiently.
 
  • Septic System Coordination: Many homes in St. James still rely on aging cesspools. With Suffolk County’s strict nitrogen-reduction standards, major renovations often trigger a required upgrade to an Innovative and Alternative (I/A) Septic System. We manage this entire process, coordinating with sanitary engineers and installers to ensure your project stays compliant and on schedule.
 
  • Water Pressure Solutions: Due to the dramatic elevation changes in the area, water pressure can vary significantly between neighborhoods. During your kitchen or bath renovation, we assess your plumbing needs and can coordinate the installation of pressure-boosting systems to ensure your new rainfall shower works exactly as intended.
 
  • Site Grading: The hilly terrain that makes St. James beautiful can also cause runoff issues. We ensure proper grading and drainage around your foundation to protect your home from water damage during heavy storms.

CUSTOM DESIGN & BUILD

Updating High-Ranches and Historic Colonials

We tailor our renovation services to the diverse housing stock of St. James.
 
  • High-Ranch Transformations: The "High-Ranch" is a staple of St. James. We specialize in transforming these layouts by removing the wall between the kitchen and living room, creating the open-concept flow that modern families desire.
 
  • Historic Restoration: For homes near the Lake Avenue business district, we provide sensitive exterior renovations. We replace siding and trim with historically accurate materials that respect the village aesthetic while reducing maintenance.
 
  • Luxury Extensions: Whether you need a master suite addition or a new great room, we design seamless extensions that blend perfectly with your existing home, adding square footage without looking "tacked on."
