The threshold of the hotel wooden door is relatively loose, and the sides and walls are relatively old. What can we do to thank you?

First, straighten the threshold, drill a small hole where the screw needs to be screwed, position it directly on the wall, and then remove the door frame. Drill a hole with an impact drill at the location to put the expansion glue, then move the door frame back to its original position, aim at the expansion glue, plug the big gap with sawdust and level it, then screw it, and at least six screws on one side will be stable!
