ᐅ Door frame does not fit / no sound insulation

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?

Somewhere I read that a reduction of 5 dB feels like 10 dB. Let’s see if it makes a difference in everyday life.

I think you mean that the decibel scale increases exponentially. A 10 dB change is roughly perceived as doubling the noise level.

That could certainly be the case. In any event, it clearly made a difference.

Why wasn’t a wooden strip used to fill the gap?

They did it the same way here as well.
