A sticking door is a common problem that can be frustrating and inconvenient. There are a few simple steps you can take to repair a sticking door yourself. First, check to see if the door is rubbing against the frame. If it is, you can adjust the hinges to fix the problem. You may also need to lubricate the hinges with a silicone-based lubricant. If the door is still sticking, you may need to replace the hinges.
It is important to repair a sticking door as soon as possible to prevent further damage to the door or frame. A sticking door can also be a safety hazard, as it can make it difficult to escape in an emergency.
