Who should I find to repair the broken door frame?

If the door frame is broken, you can find the following personnel or institutions to repair it:

1. Property maintenance personnel: Property companies usually have specialized maintenance personnel who are trained and have relevant maintenance skills and tools, and can handle all kinds of maintenance problems, including door frame maintenance.

2. Professional maintenance personnel: If the damage of the door frame is beyond the handling capacity of the property maintenance personnel, or you want to ensure that the door frame is professionally maintained, you can find a professional maintenance agency or technician to repair it. They can repair the door frame according to the type and specific problems, and may need to buy or rent necessary tools and components.

3. On-site maintenance service: If you have certain knowledge and skills of on-site maintenance, you can also try to repair the door frame yourself. You can find the relevant maintenance guide or tutorial to understand the steps and tools needed to repair the door frame. However, it is necessary to ensure adequate safety awareness and skills to avoid further damage or injury.

It should be noted that you must understand the responsibility before asking a professional to repair it. If the door frame is damaged by human factors, such as children knocking on the door frame with toys, or pets scratching the door frame, then you need to bear the repair costs yourself. If the door frame is damaged due to force majeure factors, such as natural disasters, you can contact the property or developer to seek relevant solutions.
