Hi, I need some advice on a window replacement. I am having a window company (not chosen yet) replace our nasty old aluminum frame windows. In the kitchen, we have a large slider window. The top ledge of our granite counter top is built up so that it is a little higher than the bottom of the window, it probably is glued up to the same sill board that the window is resting on.

The installers we have had come out to measure (3 so far) all propose to build up the sill, leaving the granite in place, and then installing the window so that it overlaps the granite on top 1/4"-1/2".

This worries me because it means that if down the road we want to redo our counter tops or cabinets, we will have to figure out how to get the granite top ledge out of there without wrecking the window.

Would the right way to do this be to have a granite guy come out and remove the top ledge, have the window installed, and then trim the ledge to fit back in its old place? Or is this too risky because it has a good chance of being broken during removal?
