QuestionCondensation in double glazing - what are the solutions?

Just moved in to a house which has a number of windows with condensation between the glass panels. Can they be cleaned or do they require replacing? Thanks.

If you have condensation between the glass (double glazing), it means your units have broken down, best to get a window fitter out to measure up for new units, he will need to remove a couple of beads to also measure thickness of glass.
Although some window firms have a device for this.


hi, re: double glazing condensation, the seals have broken and you will need to purchase new glass units to fit the original windows.

the only way to cure this is to replace the glazing units, the frames will be o/k, post a job on this site and get several quotes from tradespeople in your location,regards Terry.

i am not an expert on double glazing condensation but i think you may need to replace these units ..not much help ..but good luck


The only solution is to replace the glass units. Many suppliers offer long guarantees on their windows so if you could find out when & who they were supplied by they may still be under guarantee.

hi ,if there is condensation in double glazing the seals on your units have gone or there is a small crack in the glass, either way you would probably be better off (and cheaper) replacing them.

It does sound like the seals have gone on the units which means they will need replacing

Most companies do give a 5 year guarantee when they supply new double glazed units, I would check this. This covers when there is condensation in double glazing.

You can still get condensation on the units where they can still be ok this usually happens when clothes are being dried in a room when it is cold and wet outside.

You can get information from Pilkington K glass site just put in condensation and it will give you good information.
