As of 2015, replacement windows cost between $300 and $700 per window when the existing window frames are used. Some windows cost as much as $1,000 for each window, depending on the type and window and the manufacturer.
Windows with argon gas and double and triple-glazed windows generally cost more than standard windows. The cost of the replacement windows is also higher if the frame needs to be repaired or replaced entirely due to damage or rotting. The average cost of replacing all windows and frames in a home ranges from $5,000 to $40,000. If the contractor is also responsible for disposing of or recycling the old windows, the cost is often higher.
