    A couple of double glazed panes on my front window are "steaming up". Obviously, the seals have gone.
    My options are:
    - Replace the panes. Could be expensive, given they are large and have leading inside.
    - Some companies offer to "reseal" such double glazing. Would probably be cheaper, but is it a reliable long term fix?
    I welcome your recommendations and personal experiences on this topic.

    If you search the forum for something like “double glazing condensation” I think you’ll find that the experts here are not enthusiastic about the possibilities of resealing. Not that I know anything myself...

    if you can find your local "double glazing repairman" I think there is a good chance you will be pleasantly surprised how how cheap and easy it is. Mine are not very big but averaged around £50 a pane.

    Personal recommendation is the best source.

    An internet advertising website, where the traders pay to be listed and unfavourable reviews seldom appear, is not a personal recommendation.

    I would be very surprised if anyone is resealing a clear sealed unit, the time it takes to take apart the old unit , clean it up enough , and then reseal it..it will be cheaper to have a new unit. If it's a company offering to remove them then reseal them then I'm even more sceptical, as they have to visit your property several times ( remove old unit , take it away, then come to refit after resealing ) , they also need to factor in what they are going to put in the sealed units place whilst they are doing that. It is much more cost effective to have a completely new unit. The only time we would recommend ' stripping and resealing' is if there is something special about the unit...eg decorative glass. For what it's worth we replace sealed units in wood, aluminium and pvc all the time , so trust me when I say it's not cost effective to strip and reseal
    As a comment aside to actually stripping and resealing ..if the current unit is going ' milky ' , it's a new unit every time , as that's calciumification and you will never get rid of the marks ..it may look like you have but a ' rainbow ' effect will always be present at certain lights and angles.
