Hi everyone just a quick query Im due to fit a dry verge system to a bungalow which already has the front done and they want the back done now so it matchs purely for cosmetic purposes as the mortar is sound. Im just wondering wether i need to remove the mortar as for one if the mortar is sound could be a pain to remove and secondly i dont really want to damage any tiles in the process so i was wondering if I would be able to plug and screw a baton into the mortar and then fix the dry verge system to the baton ?
