1. Replace the door frame: If the distance between the door and the ground is too small, consider replacing the door frame. Replacing the door frame can increase the distance between the door and the ground, thus avoiding the problem that the door scratches the floor.
2. Replace the door leaf: If the distance between the door and the ground is not enough, consider replacing the door leaf. The way to replace the door leaf is relatively simple, but we should pay attention to whether the size and type of the door leaf are consistent with the original door.
3. Adjust the height of the door frame: If we are not going to replace the door frame or door leaf, we can try to adjust the height of the door frame. This requires some tools and skills. If you are not familiar with it, please ask a professional to operate it.
4. Add a doormat: If the distance between the door and the ground is not great, consider adding a doormat at the bottom of the door. The door mat can increase the distance between the door and the ground, thus avoiding the problem that the door scratches the floor.
Generally speaking, the problem of scraping the floor when the door is short can be solved in many ways, and we can choose the method that suits us. However, before any operation, you must ensure your own safety and correct operation.
