6 large windows in my house are rather old upvc - at least 20+ years as they are pre Fensa.
The catches are temperamental, apparently they are glazed from the outside which is a security risk, some of the hinges are a bit wobbly and one has snapped so that pane can't be opened, some of the panes are starting to mist inside the double glazing unit.
I'm wondering if I should just get the hinges and catches repaired/replaced or if I should bite the bullet and replace the whole windows. I'd love to replace with proper timber windows but I can't afford to so it would have to be upvc again. I feel like the current windows are pretty thermally inefficient but I've no idea how much better modern ones would be.
Anyone able to offer advice?
