About JDG — Centereach, NY
Concrete
first.
JDG Concrete & Construction is a general contractor based at 84 S Washington Ave in Centereach. Concrete is where we started; the work now runs from the foundation to the roof line.
Why a concrete contractor became a general contractor
Concrete teaches you to look underneath. A driveway that cracks or a patio that holds water failed below the surface. The same is true of roofs, siding and basements.
So JDG grew from concrete and pavers into kitchens, baths, basements, painting, roofing, siding, gutters, additions, ADUs, storm repair and insurance claims. Different trades, one habit: ground and water first, then build up.
