Condensation on double glazed units

[axg]

Can anyone advise on what is the best course of action.

I have recently bought a house which had double sealed non-vented units put in around 1998. Every morning the windows stream with condensation, not just a little but a lot.

Do you think I need to replace the sealed units or should I replace what are structurally sound frames with ones with vents?


Any advice?

You need ventilation, [no need to touch the windows unless sealed units have failed] just put a small vent in each room.

does anybody drape wet washing around the house, or hang it on radiators?

You can often retrofit window vents in upvc frames if they are deep enough. eg. http://www.handlestore.com/category/Trickle-Vents/0/
