It depends on sizing, framing, glass, and your budget. Size will actually be your most important factor. For the average vinyl window, the low-end cost will be about around $650, give or take. You might have some small little bathroom ones, which will be cheaper, but let’s say $650 for a single-story house. That’ll get you an XO-sliding window. It might cost more if you have a two-story home, depending on where you want the replacement window located. But $650 – $1,500 is the average pricing. When it comes to doors, that starts at $1,500 and it goes up depending how the factors I mentioned: size, framing, glass, or other accessories like sound or sun-shield packages.
