No, why:

I would be interested in the T&Cs of the Allianz, whether they pay if you build with a general contractor and not with an architect.
To my knowledge, it is the risk of the construction managers if damages occur due to the trades.
The builder accepts a defect-free house. If defects are present, the construction manager must have the defect rectified.
If the defect is only noticed later by the builder, it must probably be proven that this defect was caused by the trades and not only later.
You also cannot simply google a contribution rate, since only advice is mentioned there.

If you have the insurance, I would be interested in how much you pay.

Hello, no, I did not conclude with Allianz; however, with another insurer. Costs of the insurance between 300-800€ one-time for 2 years. Insurance amount naturally dependent on the construction volume! Regards Barossi

Damages

They just need to be defined! The layperson would say the scratched door is scrap. Get it out, new one. In total not less than 5,000 euros, preferably more. Upwards basically open. However, the insurance, the craftsman, the builder, the general contractor, the forum say: The damage is 250 euros (see #4, #5 and #6). So what good is insurance to you? (A new car buyer would not accept such a scratch. In this respect, building a house is something special.)
