Window installed crookedly - How much discount is possible?

Hello,

in our newly built house, unfortunately, a window in the bathroom was installed crookedly. This only became really noticeable after the windowsill (and thus the entire bathroom) had been tiled.

The interior windowsill has a width of approx. 60 cm. On the far left, it is 21.5 cm deep. On the far right, only 20 cm deep.

The window can be opened and closed normally. It stays in position when left half-open. From the outside, the crooked window is not noticeable – unless you measure it.

I do not want to have the tiles broken out, the window torn out, and a new one installed correctly. That would be a bit exaggerated. Nevertheless, I did not order a crooked window for my house. My question is therefore – what is a realistic amount that I could propose as a price reduction to the construction company? I think an agreement can certainly be reached. They also have little interest in tearing everything down again.

The window is approx. 80*40 cm.

Thank you

My layman’s assessment:

One thing at a time: You should keep to yourself that you have no interest in having the window removed again. First, you should formally complain about the defect in writing and demand a remedy within a reasonable deadline (3 weeks?). Additionally, you can announce that you will withhold part of the payment until the defect is repaired. The appropriate withholding amount is 2 to 2.5 times the cost of remedying the defect. The defect remedy costs result from the expenses for removing and reinstalling including all ancillary work such as tiling, etc. The withholding will therefore probably be comfortably a four-digit sum. However, if plaster and tiles are not from the same contractor, it becomes more complicated.

Are window, plaster, and tiles from the same contractor? If so, I would insist on the window being installed straight, but the contractor will probably offer you a financial concession on their own, which might amount to about half of the aforementioned withholding.

Are you sure it is the window and not the plaster or the tiles?

Nobody likes to give money back, but services in kind usually go smoothly. Window installers usually have connections to [Plissee] and similar things. How about a set of [Plissee] for some windows instead of money? It would definitely be worth considering.

What’s important is that the visual defect doesn’t bother you. Neither the few hundred bucks nor a few [Plissee] will make you overlook a visual defect if it really bothers you.
