Colonial Marble & Granite

Colonial Marble & Granite is a Wilmington, Delaware fabricator offering custom stone countertops for kitchens and bathrooms, with general contracting capabilities that extend their scope beyond countertops alone. Located in Delaware's largest city, they serve a market where older homes frequently need updated surfaces in both new and renovated spaces. Their review count of 26 reflects a business that's handled a meaningful volume of projects in the area. Free estimates are available, and they manage the full process from template to installation.

Colonial's services span custom countertop fabrication, template and measurement, edge profiling, sink cutouts, and installation for both kitchens and bathroom vanities. Their general contracting background means they're equipped to handle the broader context of a countertop project, including coordination with plumbing rough-ins or cabinet work happening on the same job. Edge profiling options allow customers to select a finished edge style that matches their space's design. Sink cutouts are sized precisely to your specific sink model, whether undermount or drop-in.

Fabricators with general contracting experience bring a broader view to countertop projects, which matters when a kitchen remodel involves more than just swapping stone. In Wilmington's older housing market, that kind of cross-trade awareness helps catch problems before they become installation-day surprises. Colonial's experience across both residential and contractor-driven projects gives them practical knowledge of how countertops fit into larger renovation workflows.

You start with a free estimate to review your space and discuss material options. Once a material is selected and a contract is in place, a technician returns to take precise template measurements. Fabrication at their shop follows, during which the slab is cut, edged, and prepped for your specific sink and layout. On installation day, the team arrives with the finished stone and sets it in place, making any final field adjustments needed for a proper fit.

Colonial Marble & Granite is based in Wilmington and serves customers throughout New Castle County, Delaware. The northern Delaware region, including communities near Brandywine Hundred and along the Route 202 corridor, falls within their typical service range. Contractors working on larger projects across Wilmington and surrounding suburbs also bring them in as a fabrication resource.
