Our Velux is partially installed - is this amount of movement on the trim around the window (not flashing) normal? Is there any way to tighten it up?

 

thanks

No not normally that much movement.  I suspect they have not been fitted properly.  Take them off and re fit.

Unfinished?

Worth checking.

Definitely not normal. I have only ever fitted one, and cannot remember how the top trim went on, but it was solid when we'd done it. I hate 'instruction pics' with no words. My brain just does not work that way!

I think it's fairly normal - the Velux kits are all a bit nonsense IMO. Vast quantities of bits of ally with tabs that you're meant to bend back / self-adhesive flashing strips that are somehow meant to be watertight and UV-tolerant for the duration / dodgy pictogram instructions.
