Hi - I am planning to replace my kitchen counters with quartz stone. The problem: House was built in 1992, and laminate was put on counters and rolled up to be the backsplash, too. How can I remove this without ripping out the drywall ? It appears to go up under the upper cabinets for about 1/4 - 1/2 inch. If I have to replace the drywall, what would the typical cost be or what should it cover ? I live in Louisiana. Thank you for any help/advice - !!
