Tilt-and-slide window door does not close

Is this a new house?

No, the house is older and the window is also more than 10 years old.

Is that a new house? I would write a defect notice to the GU.

That would be bad - it looks so sagged.

:

Could you take more photos of the side with the door open? I mean of the door itself? I suspect some bolts are out of position or bent. This type of door is quite susceptible to that...

Could you also take photos of the side with the door open? I mean the door itself?

Unfortunately, I can’t do that at the moment. The storm is still raging, and I’m not sure if I can get the door reasonably sealed again. On the left, there is also a tilt-and-turn door. However, I don’t know if it is from the same manufacturer in terms of fittings. Best regards, Michael
