What are common causes of dropped or misaligned doors?

Hinges can wear or loosen, fixings may move, and a door or frame can shift over time. Changes in temperature and repeated use can also make an existing alignment issue more noticeable. Look for uneven gaps or rubbing without dismantling anything.

A professional should assess adjustment and hardware before changes are made. A dropped door may show an uneven gap, rub on the frame or require lifting to engage the lock. Causes can include hinge wear, loose fixings or movement in the door/frame; the exact reason varies.

Do not compensate by lifting hard every time, because that can put extra strain on hardware. If the door is a fire door, report faults to the responsible person rather than adjusting it yourself.
