misty double glaze window

I notice that a double glazed pane of glass in a sliding door now does get some "mist " between the panes. This means that the gas that was there has escaped. Is it expensive to replace these panes? Or can a glazing company reseal them? I assume it is done in a working day! ?

usually just the seals need to be replaced or a hairline crack is allowing moisture in - try the glazing company who installed them - check your contract/ invoice terms first and or take their advice. Glass does not need to be replaced

What Gas only air in there with moisture beads, you could reseal it yourself but there is a chance you would break glass,(big unit) Units should be guaranteed but it will be hard to get whoever fitted them to fulfill his guarantee, I'd just ask a local glazer or window fitter to re-seal unit.

For practical reasons the whole unit will have to be replaced- it's not possible (to my knowledge) to reseal an ex. glazed unit. These units are generally sealed in the factory using a special butyl mastic sealant, breaking this mastic seal to re-use the glass wouldn't be feasible. You may replace the entire unit. Genrally double glazed units have a life of 10- 15 years, anymore is a real plus.

Thanks once again for your expert advice. Carpenter.
