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.

Your building has good bones—it's served you well for decades. But now it needs big updates and repairs. Renovating an older building takes different expertise than new construction. You need someone who can work with what's there, solve problems as they come up, and maintain the character that makes your building special. That's been our specialty for 35 years. Call us to discuss what your building needs.
