Services and Process
Keystone handles the full scope of countertop work, from initial template and measurement through final installation. Their custom fabrication service means slabs are cut precisely to your kitchen or bathroom layout, not sized generically. Edge profiling is available to add finished detail to your countertop's perimeter, with options ranging from simple eased edges to more ornate ogee profiles. Sink cutouts are completed during fabrication so undermount and drop-in sinks fit cleanly without additional field cutting.
What Sets Them Apart
In New Castle County, fabricators who handle both kitchen countertops and bathroom vanities under one roof save customers significant coordination time. Keystone's building supplies background means they're comfortable working alongside contractors on larger renovation projects, not just direct-to-homeowner jobs. That flexibility is genuinely useful in a market where kitchen and bath remodels often happen as part of broader home updates.
How the Process Works
You'll start by calling to schedule a free estimate, where a technician visits your home to assess the space and take preliminary measurements. Once you select a material, a templating appointment is scheduled so precise dimensions are captured before any cutting begins. Fabrication happens at their shop, where slabs are cut, edged, and finished to spec. Installation day typically involves setting the stone, securing it to the cabinets, and completing any final adjustments so everything sits level and tight.
