Thanks folks, some good advice and tips.
My windows are internally beaded can anyone suggest the best way I might get these off? I've seen some use an old chisel, some a stiff blade scraper etc etc.
Also, in terms of replacement. What should I ideally be looking at, a local glazing manufacturer, online sellers, something/someone else?
Best,
Ns
The first bead to remove is the longest one - try in the middle, once it’s started it should begin to prise out easily.
