A Team Dedicated To You

Who We Are

Kellgard General Contracting is a full service GC licensed in Maryland, Pennsylvania, and West Virginia. Our focus is primarily high-end residential renovations, additions, exterior living areas and historic projects.

Our goal is to take your empty lot, historic building or weathered fixer-upper and create the space of your dreams. We start by getting to know you through a free consultation, ironing out all the fine details like your ultimate wishlist, budget, timeline and location. We ensure that you receive the best services by collaborating with our most trusted partners and price match competitor’s quotes to get the best price for your project. Kellgard also remains with with you a full year after project completion through our craftsmanship warranty, making sure the dream you envisioned is picture perfect for the long run.

When not demolishing drywall, we honor our communities by actively participating in volunteer opportunities and donating to various non-profits in both time and money. Kellgard is fueled by Christian values and strives to reflect such in every interaction we have.
