Should interior window sills be installed before or after the interior plaster?

How about getting your windowsills from another supplier? My stonemason delivers 5 windowsills within 4 days.

Hm, what material are yours made of? I asked several (Juramarmor), all need at least 2 weeks

Mine are made of granite.

I think Juramarmor is important to you!? Well, I would definitely want to do it beforehand, but in the end, everyone has to decide for themselves. I have also already ordered my aluminum windows from Aluminium Systemtechnik GmbH, and they will arrive in the next few days and be installed. After that, it takes about another week, and then the interior plastering will be done. However, what is important is that especially with special windows, you take care of it early on.

We also had the natural stone window sills installed by our stonemason within 1 week after he took the measurements.

EDIT: oh man, I just noticed the post is already almost 2 months old. The window sills have long been installed anyway
