On each of my past few cars the window tint had a small gap at the top on windows that roll down, though not 1/4 inch. I think my installer wanted a bit more insurance that he wouldn't be replacing peeling tint anytime soon, so he left some margin there. From the sound of it, the installer you've chosen isn't the best. I don't know what kind of car you're trying to have done but a 1/4 inch gap on the windows and a two-piece rear windshield sounds silly. I'd probably keep the tint I got from this installer as-is and have someone else do the rear glass. Just my thoughts...
