Double Glazed window 'steaming up'

May 08, 2005 10 Replies

I have a bedroom DG window that has been getting condensation build up in between the 2 panes for some years now, and would like to know whether I would be able to get a replacement 'panel' for the frame? I had the window installed 17 years ago, so would this mean 'modern' units would all be the wrong size and therefore make this impossible? Or do you reckon it should be a simple task to do?



TIA tim


it sounds as if the seal's gone you should be able to get a replacement unit from most suppliers just check the depth of the glass

Yes I guess. Reckon it would be expensive (65" x 36")? tim

Educated guess, 60quid from a glass merchant (cheaper), not a glazier. If you're nervous about fitting it then under a hundred fitted. Wooden, plastic or metal frame?

Here in Stockport there are several companies specializing in this kind of on-site repair - look in your local Yellow Pages for something like "Double Glazing Surgeon" or "Window Doctor", etc.

I have been quoted £80 a square metre.

UPVC...yea, not sure I'd want to do it myself, as I wouldn't have a clue about how to get the existing one out! tim

theres always the demisting trick. Drill small hole in corner using tile drill. Apply direct sun to window to dry it out - use mirror or other heat source if itdoesnt get direct sun. fill hole with clear sealant.

Its a repair, but one thats liable to fail again after a while, since the unit is left unsealed. But I've heard of people having no further problem years down the line, so...

If the window gets direct sun in normal use I might even be tempted to fit a filter to the hole and let it demist itself effortlessly in future.

They probably take the sealed unit apart, clean the class, and reassemble with new dessicant seals. Saves replacing the glass itself which is fine. You might even find a local glazing unit manufacturer who will do this while you wait if you can live with a large hole in the window for a few hours.

Whilst the unit is out of the window, check the drainage holes in the frame. The most common reason for failure of sealed units is they end up sitting in a puddle of water in the frame because it can't drain out. In cold weather, the puddle freezes, stressing the dessicant seals. The water should be able to freely drain out of the bottom of the channel. (Water will always get in there as the rubber weather strip is not completely waterproof.)
