Almost two years ago, we received new units (1 window, 1 door) from a window manufacturer. Previously, we had used Veka products for almost 40 years. Because of the convincing quality, we chose elements from the same company again. The installed units are from the series VEKA Softline 76 AD.
At the junction between the door and window (transition), we have recently noticed that the gap at the top has widened, so it is now visually noticeable at first glance.
We are concerned that the gap might continue to increase over time, possibly causing further damage such as leaks, stress damage, etc.
The window installer told us that this is a "movement joint" which can change due to temperature-related expansion or contraction. They said it cannot be guaranteed that the gap – the visual impairment – will get worse. They also said it cannot be fixed or repaired, only covered with an adhesive strip.
Now we are wondering if it really is a movement joint and if such extreme irregularities can occur over time, and whether a repair is truly impossible. Nothing like this ever happened with our old units. Covering the appearance with an adhesive strip feels like a “dirty” solution to us, since we did not buy the units to look like that, and if the gap grows larger, the adhesive strip might even come off over the years.
I look forward to your support.
