Bathroom renovation: Liability issue (Not an old building!)

We want to renovate our bathroom and have a quote from the installer for this. He writes that no liability is assumed for damages (cracks) on the opposite wall. Is that correct? He can't just roughly damage the house without making sure everything is repaired, can he? He must be insured for something like that, right? Or does it work according to the motto: bathroom is finished, house is broken?

The house is not broken, but apparently your wall construction is such that he fears cracks. It's logical that he wants to exclude the risk. Contractual freedom still applies. How old is the house?

17 years. Are craftsmen not insured? If further damages are excluded, why should I then use a certified craftsman? Then I might as well take one from Ebay. He is cheaper and does not take liability either. It can’t be that I pay 25 thousand for the bathroom and then also be liable for all further damages caused by negligence or even accidentally.

Calm down. Nobody wants to deliberately demolish your house just because they don’t take responsibility for walls they don’t know. Always stay calm and objective. Nothing has happened yet!

I am quite calm. I am just puzzled by the additional remark. As far as I know, craftsmen are insured. This gives me an uneasy feeling about whether that is really the case.

A burnt child dreads the fire... Maybe the craftsman had problems with a customer before (whether his own fault or not) and is now taking precautions. Talk to him about it. But if the basic trust isn’t there, why don’t you accept another offer? (There are always residents who report after construction measures that cracks have appeared in their house since the street was renewed. Only an expert can then prove the opposite... The craftsman surely doesn’t want to harm you, but he also doesn’t want to walk into an open trap.)
