We had a garden window with a cracked vertical pane and a fogged top pane. Chris replaced both panes within a week of providing his estimate, which was 1/2 the timeframe he originally provided. How he managed to do it by himself on a ladder 12 feet above the ground, I don't know?. When he was done, I didn't realize he had put the glass in already. It was so clear I thought the glass was still missing. I couldn't be happier
