We're based in Branchville, NJ and proud of it! For over 35 years, KG has been part of Sussex County, building commercial spaces where businesses grow, homes where families put down roots, and landmarks that have stood for decades. From building to solar, when you work with us, you're working with your neighbors.

Many of our clients who want to break ground in spring start the process in the fall. Permitting, design, and planning take time. If there's a project on your radar, don't wait. A conversation now can keep your project on track later!

KG is one of the only contractors in Sussex County equipped to self-perform site-cast tilt-up wall construction. Why does that matter? You have access to cutting edge building techniques without having to find contractors that travel. We’re familiar with Sussex County and have strong relationships with other vendors and contractors in the area. If your building project is a candidate for tilt-up, contact us first!

KG has been installing solar since 2010 and has overseen more than 5 megawatts of installations. What sets us apart from most solar contractors is our construction background. That means cleaner installs, better coordination, and a finished product that performs and looks sharp. Curious whether solar makes sense for your property?

Having a contractor that is familiar with the structures on which they are building ensures you have the safest and most professional installation possible. KG brings both solar and contracting experience to the table to guarantee success on your solar project.
