    The heating bills on my flat are extortionate and I believe this is du
    to the draught from my windows. The rubber sealant is ruined. Any idea
    on how I go about replacing it? I phoned window ppl from my yellow page
    and was advised I would probably have to replace all the windows

    Which seals are you talking about? Is it the glass to frame seal or
    the frame to outer frame seal. I had the same problem but double
    glazing guy came round and showed me it was the hinges on the opening
    windows that were worn and they were not pulling the opening window
    tight on the frame seals.

    £150 to renew hinges on whole of house. You might be lucky.

    If it's the rubber strips on the moving bits, then a roll of draught
    excluder from one of the sheds should do - it certainly did it for my
    daughter's windows.

  6. One technique like this is to smear Vaseline on one surface then put a
    bead of silicon on the other surface. When they are closed and the
    silicon allowed to cure it will only stick to the non-Vaselined surface,
    thus creating a tight seal.

    Never tried it myself. I'd be cautious about using plenty of Vaseline
    on all adjacent surfaces in case I siliconed the window shut completely!

  7. Could be avoided by using clingfilm, vaselined where the silicone should

    I got a follow up question:
    If it's the gap between the window frame and the wall, can I put the silicon sealant over the existing clear sealant?
