replace double glazing unit

[mickcoulson]

hi.... I am having a go at replacing a small double gazed unit in a small bedroom ( misting up, seals are knacked ) no matter how I try I cannot get the upvc beading out. the internet says just shove a thin chisel in the joint and prise out, but this is not happening and I don't want to use too much force for fear of damaging the window the beading is mitred.
help please

Try using something like a flat knife or scraper. You might have to really work it in.

you may need to take the gasket out of the other side to 'loosen' the glass and beads. if not keep trying with something sharp, try one of the longest beads first and start in the middle

Warming the plastic can help, clothes soaked in boiling water, put on bottom centre bead. I had to use a trimming knife to open up the crack to .5mm (??) enough to get the edge of a scraper in between the bead and the frame.

I also start with a stanley knife blade, on the longest side of the frame. Gently tap the sharp side of it in to the beading crack and it'll give you a 1mm wide crack to start working with.

Depending on the beading design, you can then normally get a small sharp flat headed screwdriver down the back of the beading and then pull it out (but without levering against the frame plastic - hold the screw driver with two hands!)

The small frames are the worst!

maybe a daft question but are you trying to take the beading off from the right side?
some windows are beaded from the outside, then a either a rubber seal pushed in from the inside or sometimes they are stuck in using double sided tape

You need to remove the gasket on the other side...

The rubber seal, pull it out carefully, once it's out rattle the glass till it's loose.
