Rejuvenating uPVC window seals

Blueyonder · 2005-11-20T21:13:04+00:00

I have PVC windows about 15 years old. The windows and glass are good (no warping), but the seals are not working properly. Is there any way I can rejuvenate the seals, to get them a little more flexible again?The seals look to be black rubber of some sort, V-shaped, with a little T-protrusion hanging off one side that slips into a groove on the window frame (kind of like this: V+). The seals have basially closed up through being closed over the years. Can they be softened so that they open up again? Is there anywhere to buy new seals from (I've looked everywhere - no-one seems able or willing to supply a consumer).In the meantime, the winter wind howls through the gaps around these windows. The gap that needs sealing is about 6mm (same seals used inside and outside), and the V-shaped seals have closed to about 5mm. I can't see anywhere to stick on any additional seals.-- JJ

Thankyou. I don't think I have ever seen so many rubber extrusions, in one place, in my life!

Then you can just replace the glass units for a fraction of the cost of new windows. This replacing windows after 15 yrs is a crock especially if they have been maintained

indeed, so many people fall for anything these days. No-one should buy windows that are kaput after 15yrs. If you get here via a saner portal you'll see recent posts rather than old ones.
