Could mould be connected to broken double glazing seals?

[Oldisthenewblack]

I think the seals are gone on the double glazing in my bedroom. There is misting in between the panes and I'm sure there are gaps as I can hear the outside noise much more than when I moved in. It's a housing association property so have made an appointment for someone to come round next week to replace whatever needs to be replaced.

I'm wondering if this issue with the double glazing (it's been like that for quite some time - yes, I should have addressed it sooner) could have contributed to a mould problem in the room?

There appears to be a mould issue going on though there are no obvious patches anywhere on the walls. The mould seems to bloom on certain items around the room, it's appeared in a jewellry box near the window, plus some clothes that are in chest of drawers by the window, and on my bed frame. Also on an item at the opposite end of the room. When I first moved in I never had an issue with mould, so I'm connecting the two and hoping someone can maybe give me any insight?

I do ventilate the room every day for several hours. I open all the windows in my flat when I go out, including in the winter!

Thanks in advance

What floor is your flat on - top, ground, middle? It sounds to me as though there are other issues in addition to the windows.

wowfudge - I'm on the fourth floor of a high rise, twelve floors in all. None of my other windows have had this issue and I've been here 15 years.

Shamelessly marking my place....I hate mould...sorry you are plagued with it, OP.

[Oldisthenewblack]

It's awful, isn't it, Colly? I'm just hoping that the two are related then once the windows are fixed, maybe the mould will be too! It'd be easier if there were large patches, but there are none. It just blooms here and there, and looks just like dust but I can tell by the pattern that it's not.

I suppose it depends on the type of mould. If it is the type due to inadequate ventilation I would have though the windows being draughty would actually reduce the mould. I think you can rule out rising damp on the 4th floor

I'm wondering if you've got a slow leak anywhere or if the pointing on the external walls needs re-doing. Is there an air brick which is covered over/blocked up?

[Oldisthenewblack]

Yes, Odd, I guess that's something I can rule out . Ventilation is good. Despite the seal being broken, and yes, a draught can be felt here and there, condensation still gathers on the window when it's cold outside. All very strange. Looking forward to getting the window replaced at any rate.
