    The seals in the glass panels have failed. This reduces the energy saving efficiency and insulating factor of the windows. On most windows, the glass panels can be removed and replaced.

    You must replace the glass like William said. This is far less expensive than replacing the whole window. If possible, sand, prime, and paint the old frames before you have the new glass put in.This way you can sand right against the old glass and not worry about scratches. After the new glass goes in, just touch up the frames if needed. Call any glass company. They will come out and tell you if the glass can be replaced.(We had all the window glass replaced in a house we used to own.)

    Just FYI, and in agreement with above, it is wise to replace windows every 15 years or sooner. I learned that from a friend who has worked in the home improvement and construction for many years.

    I have the same issue. Would caulking around the interior glass next to the vinyl frame suffice? Or would condensation creep under the caulking cause it to separate? Thanks.

    knife.had the same problem with a wall full of large double glazed windows. this what I did. Takes work& you must be handy After removing from the wooden casing.

    cut the sealer with a razor knife and putty knife.
    scrape all old stuff off.
    clean the window.
    dry out the decasent that is inside of the aluminum frame.
    put back together using a siliconized sealer.
    leave 2 small openings at the top, one at each corner.
    use a small long tubing to SLOWLEY fill with Argon, it is heavier than air which will escape through other hole.
    seal up the 2 holes.
    get friendly with a welding shop that does Tig welding or rent tank and gauges.

    I think it would be easier to just put new windows in.

    Hi, Unless you are able to replace them, one at a time, I really can't see what you can do about them, The seals have obviously gone and as you say you can't get at the problem.

    Maybe it will be possible to just change up the sealed units and clean up the frames ready to receive them? Ask a window supplier or repair man. Good luck!
