Older double glazed sealed unit window replacement

[chaoticj]

Hi,

The lower middle sealed unit in the picture seems to need replacing - it has water runs inside it.

I've done this before using a putty knife to pop the inside beads off then suction cup holder to lift out.

This seems to be an older sealed unit and doesn't have any beads inside to pop off..

Is DIY possible, if so, how?

If not, approx cost to remove and replace? it's approx 80cm high x 67.5cm wide.

Thanks in advance!

That will have external beads. You need to remove the black ' wedge ' gasket , should prise out with a scraper or fllat bladed screwdriver, then you can go outside and physically push the sealed unit back and the beads should just unclip
