Replacing Velux Window

Sealed units can be got from any double glazing or glass shop.

You need to know the total thickness of the unit.

I would contact one or two local private double-glazing companies (*not* the national chains!). You should find someone who will come out and measure up and then make and fit a new sealed unit for a lot less than Velux are quoting.

If you're anywhere near Warwick, I would recommend Warwick Glass - but similar firms exist elsewhere.

there's a company near me that makes DG units, they'll knock up a DG pane, any size, same day if you give them enough warning and rough dimensions. I took the original glass to the factory and they did one for me while I waited, took them 30 minutes

If you can get a trestle set up for two to work on, removing a Velux sash is a doddle. They unclip and lift up and of their hinge. Take it off and have a look what you can do with it. Then, first thing next day, take it to wherever for a refurb.

You can take it off by yourself if you are competent. Also you can take it off from on the roof if you have roof ladders.

How long have you had the Velux?

Can you expand on how to unclip the hinge? What aspect should the window be in to do this? Can it then be slide directly through the aperture, or will it be necessary to tilt it slightly obliquely? I'm guessing the window unit will be about 15-20kg - it's the size and weight of the window which is making me approach the task with caution.

As it will be the first time I've done anything with a roof window, I guess competency is a difficult thing to gauge. Presumably if I end up standing around with a large hole in my roof and a mess of glass and wood on the ground 5 storeys below me I will realise I am not as competent as I thought I was...

I don't know - the window is about 10-15 years old from what I can make out.
