New countertops can be installed over existing cabinetry; however, we will NOT be able to install new countertops if the cabinets are not structurally sound or are not level. If the cabinets are not level or structurally sound upon arrival of our installers, your installation will be rescheduled once these issues have been rectified. Cabinets need to be leveled within 5/8” over a 10-foot length.
