I used Thumbtack to find three window contractors last year and got very different quotes — range was $3,100 to $5,800 for the same bow window replacement. The difference came down to glass packages and whether the structural work was included. Before your appointments, review their window catalog so you know which brand and glass package you want to anchor the conversation — it keeps contractors from quoting different things and gives you a real apples-to-apples comparison.
