Window cleaning - double glazing 29 November 2022 at 11:15AM in In my home (includes DIY) MoneySaving 14 replies 455 views

For the last year the window cleaner has been using hi-reach poles.  Now, I am noticing that all the double glazing appears to be misting up far more than it ever did.  The heating in the house is lower now of course.

Would the pressured water have been getting through the seals do you think?

Hi
How old are the windows?
Who installed them?
Are the the lower floors behaving in the same way?
Thanks

Approx 10-12 yrs old.  The lower ones are behaving the same; the north facing ones more so than the south.
They were installed at different times as work was done on the house.

Hi,

do you mean misting between the double panes?

Yes, I've bee around them all, and whilst the north facing ones do look worse due to some external condensation, they do have internal misting.

Lifespan of sealed dg units is about 10 years. I doubt very much you can blame the window cleaner since they should be made well enough to withstand rain beating on them at 50 mph or more. Which reminds me of this old advert ..

Window cleaners don't use high pressure water, it won't be that.

Hello
My sincere apologies as for some reason I don't always get the alerts  and i was out for a while and just noted your response

From what you have told me, I'm pretty sure it's not your window person. However, it is slightly odd for most of them to fail around the same time  (Can you confirm that is the case or is it only a couple of windows?)

Doe your windows have a bigger gap of about 25mm/1 inch and a black strip between the two panes as often there are better if done well,

FYI, I'm no double glazer but have loads of experience with our property and the rentals me and my family have and over the last 12/15 years double glazing has improved IMO.

Have you asked for a free quote and see what they are saying?

Good luck

Hi

No it's not  (highlighted bit) if you have half-decent windows.

We had a bit of mist in the first house, my parents, bought in London in 78 a few years after we bought the place it was a big victorian house and one of the smaller top opening units had a bit of mist in it - they were the metal double glazing and since that time' I've never seen a  misty unit and a couple of our rentals DG is over 20 years old as we got the paperwork for it.

IMO, in certain areas of the country I think there may have been a spate of awful DG outfits that gave DG a bad name at one time but I think we are over that forthe last 15 yrs or so

Thanks

I doubt it's the window cleaner he doesn't use high pressure so It's no different to when it's raining. My windows were misted up the other day for the first time, I googled it and the reply was. It's normal and tells you your windows are working perfectly.

Misting on the outside is perfectly normal when cold. Mist forming between the two panes of glass is an indicator that the sealed units have "blown".
