Replacing house windows generally costs between $400 and $1,200 per window, depending on material, size, and energy efficiency. Vinyl replacement windows are more affordable, while wood or fiberglass can raise the price. Installation adds $100 to $300 per window, with larger windows or complex installations contributing to higher costs. Energy-efficient windows may cost more upfront but reduce long-term energy expenses.

Replacing house windows involves the cost of both the new window and installation. Vinyl windows are a cost-effective option, but wood and fiberglass provide better durability and aesthetics. Energy-efficient windows help reduce heating and cooling bills, making them a worthwhile investment. Installation complexity, such as changes to window frames or resizing, can increase the cost, so it’s important to get professional installation to avoid air leaks and drafts.
