It can cost anywhere from $250 to $1,000 to replace a window with a door. The price will depend on the size and type of window that needs to be replaced. A smaller, single-pane window will be less expensive than a larger, double-pane window. And a standard door without any special features or extras will cost less than a door with added features like sidelights or a transom window. A standard window typically starts at $175 to replace with a door, not including labor. The labor cost will depend on your area but typically ranges from $75 to $125 per hour.
