Replacing gaskets in UPVC windows

Postby Steve1109 » Sun Mar 14, 2021 3:02 pm

Hi folks, this is my first post. I am looking to replace the gaskets in my upvc windows (on the frame rather than the window), as there is a gap of 2 or 3 mm down the centre of one side.
I am guessing this is a twisted frame or similar, but can afford to replace at the moment.
I expected to just pull out the old bubble gasket, and add new stuff.
The photos below might help, but the rubber here is right at the edge and is attached (glued I am guessing) to the frame.
There is a gap directly next to the rubber that is there that looks like it should be the slot for applying the gasket, but it is that close to the existing rubber that there is no space.
Any ideas anyone?

Thanks in advance

Hi steve1109
You can replace the seals - these usually have a finned younger which fits into a slot in the frame. Rather than a twisted frame it is more likely that the hinges have worn.

Thanks for replying. Is there any magic trick to gutting the current stuff off? I was expecting it to just pull away but it feels really well attached to the very edge of the frame.
