In some cases, it is possible to replace a single damaged panel instead of replacing the entire garage door. However, this depends on the availability of matching panels for your specific door model. Contact a professional garage door service to assess the feasibility and cost-effectiveness of panel replacement versus door replacement. By understanding common garage door problems and how to fix them, you can address minor issues on your own and determine when professional intervention is necessary. Remember to prioritize safety and consult a professional for complex repairs or if you are unsure about performing any tasks yourself.
