[house46uk]

the seals have perished on my patio door what can I do

I reckon I've got the same problem - but on my windows. Cold air gushes in (and rain too at the bottom apex oof each window),

What to do?

I experienced shrinking seals on my UPVC windows, leaving gaps at the corners that let the rain into the frame. The solution was simple - remove the seal (it should pull out with the help of a blunt scraper to hook it), then give the seal a good stretch to lengthen it a bit, refit by pushing it back in, and finally put a spot of superglue at each end to stop it shrinking back again. Start with the bottom and top seals then do the verticals. Mine has been absolutely fine since.
