I am having my pool resurfaced with NPT StoneScapes and the approved applicator installer suggested replacing the tile because it was probably original (1960s). They were worried that if they damaged them during chip out they would not be able to match. I agreed and made a selection. They came and installed it last week but the grout line along the top is atrociously wide. The installer grouted the space between the top of the tile and the bottom of the bullnose instead of the bottom of the precast. Is there anything we can have them do to fix this?
