Contract law, law, construction expert

Does anyone perhaps know if he is legally entitled to that?

Section 632 of the Building Code.

Audacity

Nope. Not at all.

Outrageous.
Zizzi, do you have the opportunity during the day to visit and accompany your construction site? Can you or your wife provide the men with coffee, lemonade, and cake or maybe a pot of warm sausages? Would you also slip the guys a little cash now and then? You would get a thousand times better results with that than with an expert. Build a relationship, talk to them, appreciate them, and also say frankly, men, I don't like this, can you do better? If appropriate... accompanied like that you'll get 100% quality. And pay much less. Karsten

Nordlys, I especially like your answer [emoji57] you are right, above all my wife bakes magical cakes [emoji108]

Regarding the building savings contract, I had an appointment with him to explain his services and costs, he explicitly said that our first appointment is free of charge. He gave us a few tips and finally said we will receive a protocol of our conversation today including all the points discussed as well as an offer with a detailed description of services and prices. I never applied to him.
He even argues: I also have to pay for my insurances, software, seminars, etc.

Final inspection at the beginning of September. The boss will come with the final invoice. Check all doors, inspect everything outside and inside. Etc. Then. Mr. S., the construction went smoothly. The men enjoyed being here. They felt well cared for and welcome. We earned our part. I did not charge for the Muster inspections....build relationships.

I would never build without a [Bausparvertrag]. Botched seals, slopes, connections, etc. certainly don't get better with cake and pea soup.

Yes, I agree. Karsten, you often make good contributions that hit the point. But unfortunately, with your procedure (e.g., handshake instead of contract) you are the absolute exception. If I am not an expert and work with unknown craftsmen, I have to have it checked. Currently, there is a thread running here where the connections may have been set incorrectly. That can still be judged alone, but other things the average person simply cannot.
