Condensation

If the weather has changed from being cold to mild quite rapidly moisture will condense on anything that is cold (e.g. glass). lt's all to do with the dewpoint - just physics and nature and nothing you can do about it.
As i understand it this is quite normal. We are having new windows fitted in a few weeks and were warned before hand by the glazing company to expect this. It is much more likely to occur if you have 'k' glass especially if the units are argon filled, as these insulate better than standard units, therefore the outside of the glass is quite cold and then IanDB's dewpoint comes into effect.
Hi, I'm looking into this too as we had the same problem. Previous house double glazed with argon filled but never had condensation outside, regardless of temperature variation. It spoils the view and have to go outside to wipe the windows unfortunately.
Perfectly normal with high spec energy efficient glass unit, just shows how bad even your argon units were previously though the argon has all but leaked out within 4 years or so. Condensation forming on the outside shows the glass unit is working as it should keeping the heat escaping and warming the outer pane up with heat you've just paid for, if the outer pane was warmer then condensation wouldn't appear, because its cold then it does
If you just ignore it for an hour or so, it will evaporate by itself.
