Countertop support. In most spots, your cabinetry will provide the support for the countertops, but think about what will support the counter around the appliances. A slide-in range like the one pictured has a 2-inch strip of counter behind the cooking surface. Because it is tricky to move two large slabs connected by a 2-inch strip, this spot will often be seamed together onsite. Make sure you install wood blocking flush with the top of the adjacent cabinets so the contractor can properly attach this strip.
Another common trouble spot is where a counter ends on a dishwasher. The dishwasher can't support the counter, so provide structural support on the side — ideally more than a ¾-inch fill panel.
