    Hi, we have these windows in our house - from the mid 80's - so over 30 years old, excellent quality, the wood is still in great condition. They're the kind you can pivot almost all the way round so you can wash the outside from indoors. I've posted two photos. All have now dropped slightly so the end furthest from the "hinge" scrapes on closing. They don't really have a hinge as such, they glide along inside a top and bottom runner, bit like a scalextric car. I'd like to restore them if poss. Has anyone done this? Is it a case of changing the fittings? Or maybe they've done their job, and new ones are needed?

    Is the weight carried by the top channel? The window head may have sagged over the years - could check with a straightedge, cut away some soffit plaster, re-shim and screw the head to the lintol.

    If it's diagnosable mechanical wear, pos some simple adjustment or replacement of washers on spindle type of thing?

    No, I'd say more of the weight is on the bottom channel, a photo of which I was unable to upload, but I think I may now have succeeded. The house is a wooden Swedish thing, so I don't think the head has sagged, but I will check.

    The middle screw on the bottom “hinge” could be an adjuster

    If they were mine I would not be averse to planing off some of thr wood on the sash where it is rubbing.

    The glass may not have been correctly packered into the frame and/or the corner joints could have pulled apart a touch and could be sash cramped back and dowelled

    Is there a manufacturer's name on the hardware somewhere? It looks like there might be one shown in your second photo. If so, I would contact them and ask them about maintenance and adjustment. They probably have a manual and have probably dealt with the question a thousand times.

    If there's no name, I'd show photos to local window fitters or shops. Somebody will recognize them.

    Looks gd & strong by modern standards - should be mendable.
    Posted By: minisaurusAll have now dropped slightly so the end furthest from the "hinge" scrapes on closing.

    If you put the windows at the point where they just start to scrape and then lift the outboard end of the window you may be able to detect where the play is that has caused the drop. And determining this may point to the remedial action.
