A technician then visits to take exact measurements and create a template from your existing cabinets or framing. Back at the shop, the stone is cut to spec, edges are profiled, and sink cutouts are made before the slab is delivered and installed. Most customers in the Oakley area find the turnaround reasonable for the level of customization involved.
