Granite & Quartz are extremely rigid and cannot bend to follow the irregularities of walls. No wall is perfectly straight. There will be areas where small gaps are visible. The size of these gaps is determined by the severity of the bows in the wall. Countertops receiving a backsplash will not be scribed in an attempt to follow the irregularity of any wall. A gap of 1/8” to 1/2” wide (covered by back splashes), is normally used between the granite countertop and walls in order to allow the home framing to expand and contract during the change of seasons, giving the granite room to move slightly. For areas without splashes, counters will be scribed to within industry standards. AMF, Inc. offers both stone and tile backsplashes to remedy bowed walls. These are priced separately on your quote form.
