Disputing plumber invoice

Hello guys

I was notified a couple of months ago that my bathroom (I own the apartment) was causing a water leak in the floor below, more precisely in the corridor underground that leads to the communal garage.

A plumber was called and after a long time, he disassembled the whole shower, did some work, dried everything and reassembled everything.

A couple of weeks ago we started again using said shower but unfortunately the water leak is still there. In the meantime we got an invoice for 4k approx and stopped using the shower again (good we have another one).

What is the best way of handling this ? Am I correct in not paying this invoice yet ? I already got a second mahnung and obviously haven't paid yet. Is it unreasonable to have the problem solved before paying ? What is the collective EF opinion ?

Thanks!

Have you actually informed the plumber that his work was useless??

You should have tested the shower and let him know the situation immediately and not wait for two reminders...

I called him up of course as soon as we were notified of the leak and informed him, but that didn’t prevent him from requesting his money...

From now on I would stick to registered letters, so that you prove that he was informed about the fault etc.

Also have you contacted your insurance regarding the water damage?

Is it a new build? Just asking in case there still is any guarantee.
