Please help! I've gotten 3 different quotes from 3 companies. 1st one claims he can do the coping alone for $3,100. Second guy says must do the tile also, total price $5100. Third company tile and coping $12,000. Anyone with any info on what is reasonable here. The prices vary so much and I just don't know what is normal for the area. Has anyone done just their coping and was it successful? Any feedback would be appreciated.
