About Us

More Than Just Concrete

Structural concrete is our forte.

From casting the deepest below-grade garages to raising the tallest buildings in the D.C. area, Miller & Long builds safe and lasting concrete structures.

Jack Miller and Jimmy Long founded the company in 1947, pouring concrete for driveways, curbs, gutters, and sidewalks. Today, as a self-performing, turn-key, structural concrete subcontractor for buildings of all shapes and sizes, Miller & Long draws on more than 75 years in the construction business to offer a full suite of award-winning services.

From providing our own machinery and equipment to employing personally trained, high-caliber skilled trade and project management professionals, Miller & Long is trusted to build strong, functional, and efficient structures that stand the test of time.

From bid to topping out, we deliver:

  • Preconstruction services
  • Formwork installation
  • Hoisting
  • Rigging
  • Concrete conveyance/pumping
  • Concrete finishing
  • Erecting/dismantling of tower cranes

Indeed, we are a one-stop subcontractor that gets every project done – and done right – no matter the size or complexity.
