Hello everyone,
The interior doors have been installed in our new house. The measurements were taken before the tiler came. The walls were then tiled up to halfway, which meant that the door frame no longer fit because it was too narrow. The installer planed part of the door jamb but couldn’t go further due to stability concerns.
Now we have a large gap between the door frame and the wall. This is a disaster in terms of soundproofing, and any door installed would have the same problem. The company refuses to replace it, saying the fault lies with us. Regardless of who is to blame, I will take care of it myself.
How can I improve the sound insulation? Should I install a joint seal profile and seal it with silicone (see pictures)? Additionally, should I foam the entire area with expanding foam or something similar?

It's not about the noise coming into the bathroom, but which noise goes out. That won’t change much, no matter what you do. It’s better to simply close the child’s door in the morning.

Listening to music will also become an issue later on. Is it the child’s annoying music leaking into the bathroom, or the parents’ pop music bothering the child? Who actually needs to be protected?
Besides the fact that it is simply sloppy workmanship.
I don’t understand why the gap should have any effect on the sound insulation.
The door frame should actually fit tightly into the wall opening; whether there is a gap on the inside or outside next to the wall should be irrelevant.
Who is responsible for the planning? In my opinion, either the construction manager or the tiler overlooked this. You can’t just tile halfway up to a wall opening like that.

Reini12349 Jan 2020 16:35Maybe the frame is not flush with the opening? The increased sound must be coming from somewhere. The tiler didn’t mention anything about the doors, so I just let him do his work.
I agree with @Otus11. A tile installer must know that you cannot install tiles like that. The tiles need to be removed and then fitted properly after the door frame is installed according to professional standards. An acrylic sealant joint is then applied, and that’s it. However, the door installer should not have installed the frame like that either! Therefore, each trade is responsible for their costs due to poor workmanship. Anything else would be shoddy work again.
It seems to me that the site management has messed up the coordination between the trades here. The tiler doesn’t know what the door frame looks like, and the door installer is unaware of a half-height tiled splashback. Neither seemed willing to accept an additional trip, so both just went ahead on their own. We had the door frames in the bathrooms installed first, and only after that did the tiler come in.
