Removing Rubber Seals(Gaskets) in UPVC Windows

[jam00]

Hi All

I am trying Remove the Rubber Seals(Gaskets) on my 10 year old UPVC Windows ,the rubber seals on are the outside and having a nightmare trying to pull them out they are so tight,this is so I can remove the windows beading in order to replace a double glazing unit.

Any advise on how to remove them would be great, using pliers did not work just damaged the seals.

Kind Regards

Unless I misunderstand you, the glazing beads are removed first, followed by the double glazed unit. The rubber seals should be left alone, ready for the replacement glass unit.

It sounds like you have gasket known in the trade as 'firtree'....

This isn't exactly firtree but it gives you an idea how its clipped in all the same, to be classed as firtree it should look the same as the rubber on the bead, effectively looking like half a firtree

Virtually impossible to remove without damage, your internal beads will be effectively spring loaded and this is all thats keeping them in, a sharp ish putty knife/scraper in the joint will flick them out, start in the middle though as you'll have more bend in the bead
