mould on window putty

NowRetired

My grandson and his partner have just bought a dive, sorry new home, in which the windows are wooden framed single glazed and must have had a lot of condensation running down them as the putty is absolutely black with mould.

The previous owner was an old woman who did nothing to the house, it needs completely modernised and redecorated.

How do people live like that?

New double glazed windows are a few years away.

What's the best way to treat the mould on the windows?

I say let some bleach run down the window into the mould and leave for a few days but they are not too keen on that because of their young child.

And also think the glass will fall out of the windows :rotfl:

Any other suggestions?

Plenty of anti mould sprays available. Best solution is to remove old putty and renew, especially as windows are there for the forseeable future.

Contact local glazier for a quote or do it DIY.

If they are painted timber windows the easiest way to get rid of the mould is to cover it with new paint. Scrape off any loose mould, lightly sand the putty (be careful not to scratch the glass) and apply a primer/undercoat and a gloss. Let the paint spread on to the edge of the glass by approx 5mm to seal the joint between the glass and the frame. It will last for 3-4 years. If the windows are in good condition it might be worth thinking about secondary double glazing, particularly in a child's bedroom where condensation can cause problems.

Try Dettol Mould & Mildew remover first, tends to work quite well.
