Various defects noticed gradually

Hello everyone,

From May 2016 to May 2017 I built a single-family house of about 280 sqm on my own.
For laying the parquet floor, installing the interior doors, and for two bathroom cabinets, I hired a carpenter who was recommended to me by friends.
The problems started when the company unfortunately stood out for extreme unreliability. Some work was only completed long after moving in, which was in May 2017, and only after calling them 100 times. But that is another matter.
When it was finally finished, it looked quite good at first... but gradually more and more defects or shoddy work have become apparent. Of course, I could kick myself for not noticing this earlier. Some of the defects are also well hidden and not visible at first glance. Among others, the following defects are now known to me:

[*]Edge joints with silicone look like they were done by an apprentice on their first day; we have since had them fixed by a joint technician. (He could not believe what kind of amateur was at work there)
[*]On the stairs to the upper floor, one step is two centimeters lower than all the others (stairs were doubled up).
[*]On the stairs, two steps are missing part of the side cladding of the tread, so that you can see the cross-section of the parquet.
[*]On one door, the strike plate was dented because otherwise it wouldn't close.
[*]Transition strips on the parquet to other areas, e.g. with carpet, were not installed.
[*]In one room, the carpet floor and baseboards had already been installed by the interior decorator. When installing the door, the baseboard was not shortened but the door frame was cut out. ops:
[*]In the attic, the parquet at the door thresholds does not go under the door but ends before it. In the upper floor, the parquet extends under the door threshold and the door was accordingly chamfered.
[*]The door in the bathroom cabinet no longer closes on its own.
[*]On the base cabinet for the washbasin, the sealing tape is missing.
[*]...

The invoice, of course, has long since been paid. What would you do? Do you think it's still possible to arrange for the defects to be fixed? How should I best proceed? Or am I too late to achieve anything?

Thanks, KidIkarus

Hi

without explaining the entire warranty law in connection with contracts for work and services, the whole thing seems to be time-barred (2 years from acceptance - §634 para. 1 no. 1 German Civil Code). In case of fraudulent concealment, it would be 3 years.

Were you on vacation for 2 years?

Many things should have been noticeable?!

I can see bad silicone joints from 3 meters away.

And no, there is nothing you can do about it anymore.

Certain "defects" are due to normal use.

It is normal for a door to shift after 3 years and it needs to be adjusted; also, some seals can simply become loose.

I would complain to the "Eigenregisseur". He approved everything and released the invoices. You can always talk - so make an appointment with the carpenter and speak in person.

A few pictures would not be bad, but yes, you can't do anything anymore and many things can be fixed relatively easily. (Clearly cut door frames no longer).
