What Causes Garage Door Sagging?

As garage doors age, they inevitably begin to show signs of wear and tear, losing some of their former pristine appearance. While minor cosmetic issues like fading paint can often be remedied with simple sanding and repainting, more serious problems such as sagging require immediate attention, particularly for those with wooden or metal garage doors.

The causes of garage door sagging can vary depending on several factors, including the material of the door and the condition of the garage door opener. For wooden doors, prolonged exposure to the elements can be a significant contributing factor, especially in regions with fluctuating weather patterns like Missouri. Over time, the wood may contract, expand, and eventually warp due to changes in temperature and humidity, particularly if the garage lacks adequate ventilation.

Additionally, garage door sagging can also result from trauma or wear and tear. Ideally, garage doors operate smoothly when all components are uniform. However, wear on rollers and panels can disrupt this balance, putting additional strain on the door and causing it to sag. Furthermore, if the door has sustained damage such as dents or dings, it may not function as intended, leading to sagging issues.

Another potential cause of garage door sagging is an incorrect or incompatible opener. Not all garage door openers are suitable for every type of door. If the door is too heavy for the opener, a common issue in cases of self-installation, it can lead to sagging and other operational issues.

While many sagging garage doors can be repaired if addressed promptly, delaying repairs can lead to more significant and costly problems down the line. In some cases, replacing a single panel may be sufficient to rectify the issue without the need for a full door replacement. However, regardless of the underlying cause, seeking professional assistance is crucial to ensure that the problem is properly addressed and resolved.
