Siding Installation in Smithtown

Smithtown's housing stock spans three generations of Long Island residential construction — 1960s-era capes and ranches around the village, larger 1970s-80s colonials in Kings Park and Nesconset, and newer construction in Hauppauge and St. James. The 1960s originals often still carry aluminum siding that has faded, dented, or started lifting at the seams — a common trigger for full replacement.

Mid-range vinyl (CertainTeed Monogram or Royal Estate) is the dominant choice in the 11787 zip, though Kings Park homeowners with larger lots increasingly opt for insulated vinyl or LP SmartSide for the added R-value. Permits are filed through Town of Smithtown Building Department at 99 West Main St — our contractors handle permit applications on every job, including required setback checks for additions involving new sheathing or foam board underlayment.
