No fire protection door to the garage - whose fault?

If it is required in the building permit, the execution plans should have been changed and you should have signed again as well as received information that such a door cannot be delivered by the contractor – which does surprise me a bit, as this is not exactly rocket science.

It is a bit dumb of the construction company, but you probably wouldn’t have gotten around the costs of a special door. I would buy the T30 door and try to have them install the door free of charge.

Attention: If a fire protection door is required, this may mean that the door frame also needs to be modified. The craftsman is responsible for completing a declaration of conformity after installation, which must be handed over to the client along with the manufacturer's approval notice and installation instructions.

You probably wouldn't have avoided the cost of a special door.

Correct. In my opinion, she is not liable for the costs of - the wrong door - the installation of the wrong door - the removal of the wrong door.

The house company told me that they generally do not supply such things.

I find that quite weak.

Hello Brandt123

such a fire protection door costs 200 euros. Plus the door closer.
I would try to have the construction contractor install the door, and you provide the door.
It is quite simple (an hour and the thing is in) to install such a door, but during the building inspection you might be asked for confirmation of correct installation.
I have always installed my doors myself. Never had any problems.
