Replacing windows costs an average of $300 to $1,000 per window, depending on the type of window and its energy-efficiency. Vinyl windows are a cost-effective option, while wood or fiberglass windows tend to be more expensive. Installation adds another $100 to $300 per window. Additional features like double-paned glass or specialty coatings can increase the price.

The cost to replace windows is influenced by the type of material and the number of windows you need to replace. Vinyl windows offer a balance of affordability and efficiency, while wood provides a premium look at a higher cost. Installation costs vary depending on the difficulty of the job, but a professional installation helps ensure the new windows are properly sealed to maintain energy efficiency and improve home comfort.
