Repairing Double Glazing

BobQ

I have seen adverts from various firms who claim to offer a service in which they repair misted up double glazed units by somehow sucking out the air/water and resealing them. Judging by a quick Google it seems that many firms now offer this solution rather than replacing the window or the double glazed units with new.

I also found the enclosed discussion about this option from 2007

Has anyone any experience of having this done, seen any independent reviews of the technique?

Any views appreciated.

If its blown, its blown, get a new unit.

A new unit is enough to sort out and you could get one of the better uprated units at the same time.

We have just moved into a house where all the windows are blown. Is the costs of replacing the glazing the same (or roughly similiar) that getting it repaired? its a 4 bed detached house (20 years old).

A new unit is normally the best answer iunless it a nice leadlite or bevel etc . drilling and "sucking" out the moistureoften leaves a water mark . Splitting and resealing using a new spacer bar and desicant will work but not really cost effective.

Yes agreed but be aware that K-Glass ,Planithem and Plan-ebella [sic] have different shades once made to a stadard unit Argon filled again a different shade too. o know whats coming out to get a matching unit in.

Unfortunately, all double glazed units will fail sooner or later. I'm not convinced that even if they last 20 years, which is a good life span many won't reach, that the more expensive units with special gas fills and coatings will actually save money (compared to a regular unit) before they fail.

a basic guarantee for a dg unit is normally 5 years from the manufactuer i get 10 along side my windows but thats covered by the window company not the dg maker.
Thats for Upvc windows not going into timber or replacing failed units

If the windows are beaded on the outside, get rid of them and get new units. Otherwise you can just order the glass. I've had to remove the beading on some modern units and using a putty scraper it's been fairly easy. Start on the long beads and then do the short ones. measure the actual glass and order - shouldn't take long. When putting them back in, do the shortest ones first.

Well that was my question!

I have seen adverts from one firm who do the repairs and they say its guaranteed for 10 years (insurance) and costs £50+VAT per pane. But I have no idea of the pros and cons. Although one pro is that because its done in place it may be a solution for windows that are difficult to access such as dormer window.
