About GWJ Granite
For over 10 years, GWJ Granite has grown from a small countertop shop into a full kitchen design and cabinetry studio — without losing the part that made people refer us in the first place.
We do the work ourselves: walking the slab yards, fabricating in our own shop, and installing the work we sold you. No middlemen, no mystery subcontractors — just craftspeople who care what your kitchen looks like a decade from now.
What we do
Pick the piece you need — or hand us the whole project. Either way, the same team is on it from first measurement to final install.
Hand-selected slabs cut and finished in-house. We help you pick the stone in person, then template, fabricate, and install with precision.
From semi-custom lines to fully bespoke cabinetry built to your kitchen, our team handles design, ordering, and installation end-to-end.
A single team for your whole remodel — layout, cabinets, countertops, backsplash, and install — so the finish you imagined is the one you get.
Bath vanities, shower surrounds, fireplace surrounds, and commercial work — if it's stone or cabinetry, we build it.
How it works
Come see slabs and cabinet samples in person, or we'll come to you. We talk through your space, budget, and the look you're after.
We help you pair stone, cabinets, and finishes — then template your space precisely so what you pick is what you get.
Cuts, edges, and cabinet builds happen here in Wilmington — by the same crew that will install them.
Clean install, on schedule, with a final walkthrough so you sign off only when it's right.
