I have a granite countertop. I needed a specialist to come out here and basically reseal the sink that was leaking. It costed me $175. When they gave me the estimate, they thought they would have to completely detach the sink from the granite. Then they would have to get underneath the sink, cut all the pipes, unglue the sink and then reattach it. Then they were going to come out the next day to fix all the plumbing. However, when they got out here, they realized that the only thing they had to do was basically re cork it above the granite. So they took off the cork that was around the sink and re corked it. They were here for about 20 minutes. They took off the plumbing fee but left the other fee on it. I thought that $175 was for completely detaching the sink and redoing all that work. They said that it was the service fee for coming out here and doing what they did. I thought that was a little unusual. I will probably use them again but I will make it clear that I need them to come out and give me an estimate based on looking at the job and determining exactly what they need to do.
