Whether to repair or replace old windows depends on several factors, including the condition of the windows, the extent of the damage, the energy efficiency of the windows, and the cost of repair or replacement. Here are some factors to consider:

Condition of the windows

If your windows are in good condition overall, with only minor issues like cracked or broken glass, damaged hardware or weatherstripping, then it may be more cost-effective to repair the windows rather than replace them. However, if the windows are extensively damaged or show signs of rot or decay, replacement may be a better option.

Energy efficiency

If your old windows are drafty or have single-pane glass, they may be significantly less energy-efficient than modern windows. Replacing old windows with newer, energy-efficient models can lead to significant energy savings over time, making replacement a worthwhile investment.


The cost of repairing or replacing windows can vary depending on the extent of the damage, the type of windows, and the complexity of the installation. In general, repairing windows is less expensive than replacing them, but if the cost of repairs is too high, it may be more cost-effective to replace the windows.

Overall, if your old windows are in good condition and have only minor issues, repairing them can be a good option. However, if your windows are extensively damaged or are not energy-efficient, it may be better to replace them with newer, more efficient models. Consulting with a professional window contractor can help you determine the best course of action for your specific situation.
