Building in the Shadow of "Whisper the Bull"

Smithtown is the definition of the classic Long Island suburb, anchored by the iconic Whisper the Bull statue and the historic charm of the Village of the Branch.

The housing landscape here is diverse, ranging from the stately Colonials and Ranches on the tree-lined streets of The Landing to the new wave of "smart growth" luxury lofts and townhomes rising near the train station, like The Lofts at Maple & Main.

At J.B.T Contracting LLC, we understand the standards of this community. Whether you are modernizing a Split-Level near Blydenburgh County Park or customizing a unit in a 55+ gated enclave like Country Pointe Woods, we provide the licensed craftsmanship required to match the prestige of Smithtown.

MANAGING THE TERRAIN

Overcoming Groundwater & Slope Challenges

Smithtown’s geography presents specific challenges for homeowners, particularly regarding water and terrain. We offer construction solutions designed to protect your home in these conditions.
 
  • High Groundwater Solutions: In many residential pockets of Smithtown, the water table is exceptionally high, which can threaten basements and foundations. We specialize in industrial-grade waterproofing and interior drainage systems to keep your lower levels dry, a critical step before finishing any basement in this area.
 
  • Steep Slope Grading: With little vacant land left, many renovations and extensions take place on the town's remaining hilly terrain. We expertly manage site grading and install retaining walls to control erosion and ensure your new structure is stable.
 
  • Renovation Coordination: We understand that many Smithtown homes rely on private septic systems. When planning a major renovation (like adding bathrooms or bedrooms), we manage the project timeline to coordinate seamlessly with your sanitary engineer, ensuring your site is ready for any necessary system upgrades required by the town.
