ᐅ Are cracks in window sills normal?

After returning from our vacation, we visited our construction site for the first time today. In the meantime, the internal window sills have been installed. We were shocked by the many cracks.... Of course, it is a natural material, but it really doesn’t look good. Is this normal and something we just have to accept?

Another question: Our front entrance door has already been installed, even though the interior plastering hasn’t been done yet. We have already noticed some scratches. The door wasn’t covered at all to prevent damage. The interior work is only just beginning, and different tradespeople are coming and going. How was this handled in your experience, and who is responsible for any potential damage?

Thank you for your opinions. We’re a bit upset with the carpenter right now.

No, door frames are always installed after the interior plaster. Frames may only be installed beforehand if they are flush-mounted.
You can easily see this in practice when visiting older buildings, where there is always plaster beneath the frame.

If you install the frame before the plaster, you are also installing it before the screed. Therefore, you practically cannot install the door frame beforehand, as it is set with a minimal gap above the screed and floor covering.

We are talking here about the front door. That is installed before the plaster and screed. It’s different for interior doors.

🙂 And now everyone reading here knows that you are planning a natural stone slab eight meters long in the kitchen. 😉

And what is so bad about that? It was meant as an example to show that size does not always matter. Not always... :-)

No, usually not. The plaster and screed leave some space. The door is installed at the very end and is slightly adjusted afterwards.

I have learned this now as well. I outsourced the doors and only followed the installation timing for the interior doors as shown on the construction plan. As a result, the exterior and interior plastering, as well as the screed, had to be done twice—once before and once after the door installation. Here are photos from outside and inside.

Hallway under construction: green pipes on the ceiling, insulation panels, unplastered walls, and wooden door.

Doing the work twice means double the travel costs and total expenses. The construction time also gets extended because the plasterers have to come right after the door installation, which rarely works out...

Just like in your case...
But it's still cheaper than constantly repairing the damage to the door. And then there are the discussions with the homeowners – as you can see here with the original poster.
