Possible to repair sagging double glazed windows?

Reue

Hello all,

Wondering if it is possible to repair upvc double glazed windows that have sagged or will it require full replacements?

We have the windows that sit horizontally with hindges on the left and right sides. Several of them have sagged so that they are now difficult or impossible to close as they catch on the bottom window frame.


Many thanks!

Presumably it's possible to lift the window clear of the frame when you close it. It seems the hinge has worn so can you move it upwards in the frame?

Google 'double glazing repairs' in your area. There are loads if companies that will repair them. It sounds like your hinges have dropped.

If i'm understanding correctly then best case worn hinges as others have said and an easy fix, worst case inadequate or no reinforcing in the sashes. New sashes if you know which profile or new windows may be the only option.

Is the sash catching on the bottom? If so the sash will need taking off and the hinges moved down the sash slightly
If the sash is catching on one of the sides at the bottom then the glass needs repacking to suit
Ring a local double glazing company

Is there no lintel above, causing the bricks above to press on the DGUs causing the sag you describe?

now that will be a can of worms....

Whilst the above responses could be correct, the main reason that plastic sashes sag is that the DG units are not fitted correctly in there frames.
If they aren't the weight goes over to the unsupported side and allows the frame to sag. removing the mitres and repacking should take up the slack.

There is more than enough adjustment in the fixing to take up any minor maladjustment. but the frames/sashes do have to be packed square
