RELATED: What to Consider Before Buying New Windows. For a complete window installation, find your own qualified contractor and window manufacturer. For a standard-size, double-hung, double-pane (energy efficient), vinyl window, expect to pay between $450 and $600, including installation. Wood windows are more expensive. The cost of a wood replacement window can range between $800 and $1,000 per installation. If the entire window and framing has to be removed (down to the studs), be prepared to add at least $50 to $100 per installation. This is referred to as new construction windows or full-frame replacement windows, and requires more work at an additional cost.
