Advice on removing Dometic/Seitz S5 window

[Familymarmite]

It seems one of the windows has developed a leak.
I would rather take the window out for a proper repair rather than seal around it.
I have spoken to a dealer who has given some tips and recommended a suitable non setting mastic sealant.
His words were good luck, the guys in the workshop hate doing them as they often break on removal.
I've downloaded installation instructions.
From what I can see, I remove the cover from the inner frame and unscrew from the outer frame. Then break apart the sealant between the outer frame and the outside panel.
Any advice before I start, very much appreciated.

Can I edit the title? It should read Dometic not Domestic.
Now done but I can't see how to remove this post.

You pretty much grasped it yes.
I would use some broad tape all around the frame to protect the body and use decorators scraper to break through the old sealant.

Here's one I fitted in mine for reference pictures

Thanks for that Techno, very useful.
What was the sealant used?

Remove see through bit of window, remove inner section, and take your time going round with long bladed knifed, whilst apply a bit of pressure. Much easier if you can get the sun on the side for a few hours before you start. All easy, just take your time, and keep everything clean as you go.

@Familymarmite One tip I remember from "Diamond Dave" on TV was to use small wood or plastic wedges to hold the two surfaces apart as you progress around the window. I can remember that it took quite a time to work my way around the Heki when I had to change the outer frame as the mastic was not only around the roof surface, but also on the lip of the opening.

Good luck

My old Autocruise had no sealant so it nearly fell out. The factory must have run out so they put them in dry and ran clear silicon around the outside. No wonder they went bust

I've done two windows. I used a big knife all around the seal.It takes time but I didn't find it too hard.If you look on YouTube there's a couple of threads to follow.
