Window showing signs of condensation

The UPVC windows in my house are showing signs of condensation and this is darkening the net curtains . Can this possibly be repaired or what can be done to correct this.

Thank you

 

There are companies which suggest they can repair and reseal them, but the other option is one of replacing the complete panel.

 

If the condensation is on the inside of the glass and the frames, simply drying it off every morning with a cloth and leaving the window open for 10 minutes would likely resolve the problem. If the condensation is between the panes of the sealed unit then the sealed unit needs replacing.

 

You need to improve airflow.

 

You need to clean up the mould which is all over the cill and which by the sound of it is all over the nets. You are causing the condensation, wipe it up.

 

Nets make condensation slightly worse, because they reduce the air flow.

 

Your problem is excessive humidity.

Find and correct the cause.

Does anybody drape wet washing inside the house, on radiators or airers?

Does your bathroom have an effective extractor fan?

Is rain getting in?

Do your windows have trickle vents or a small ventilation setting?

 

The op seems to have fired and run, without even confirming whether the moisture is on the inside, or between his panes of DG.. His 'be repaired' suggested to me that the issue was maisture between the panes of the DG.

Apologies, I was away .

Does anybody drape wet washing inside the house, on radiators or airers? yes my wife does i will have to get this stopped

Does your bathroom have an effective extractor fan? yes it does i believe

Is rain getting in? No not at all

Do your windows have trickle vents or a small ventilation setting? No it doesn't it's an old style window

 

Thank you everyone for the comments

 

Trickle vents can often be retrofitted to uPVC units. It really can be as simple as just drilling a series of whole through the uPVC frame and then screwing on the vent covers.

The above is just to show you what they look like. They can be purchased elsewhere for less.

If you are interested in fitting some, take photos of the upper parts of the windows. That said, looking at your's I suspect they can't be but others might be able to give you a definitive answer.

 

If there is some reason why indoor draping has to continue, put a line over the bath and run the extractor fan all the time, with the door and window shut. It will remove the water vapour from your home and prevent it spreading through the house.

 

Yes sadly, I would be unable to retrofit on my windows . I have now decided to change the windows. They must be 20 - 25 years old.
