thanks all didn't have time to type out much as run out of time on internet at library.

Doing customer today £18 job he phoned me up last month and in a round about way was blaming me for a blown decrocative window.

I gave all explanations and stood my ground i.e south facing windows tend to go first and all other reasons given here, in the heat of the moment i agreed to carry but use ladders, i now regret saying this and don't know wether to dump him,
leave a note saying sorry but no thanks.
Just don't feel comfortable cleaning somones windows who's going to hold me responsible for every problem on his property?

I have actually cleaned upvc with wfp and seen water running inbetween panes so it can't be impossible to get in(am i wrong)

dangerous subject!

if the seals have gone then yes it can get in, if it hasnt gone it cant.

I would avoid this customer just to be on the safe side.

I can't imagine any possible way for water to get into a double glazed unit from being cleaned with WFP.
The seal would have to be incredibly badly damaged for water to get in as a result of being cleaned, and as has been pointed out, the seal is on the top edges of the pane, and this is invariably up inside the beading holding the pane in place.
Moist air might get inside but not water in it's liquid form.

I agree with Ian, really can'r see water getting in at the top of the unit, you are probably seeing what sometime happens and the water is getting past the seal on an opening window and trickling down the insides of the glass flooding the sill

[Londoner]

Water can't get into a window unit. The only reason you might see water running down the back of the glass is if the water is getting past the frame and running down the other side, not the inside.

Condensation forms inside as the leaking unit heats up and contracts so does the air inside. When the air inside expands it forces some of the air inside out past the leaking seal. When the unit cools down again air is sucked back it from outside. However the air that is sucked back contains a little moisture which condenses against the cold glass. Next day the process is repeated and so on. Eventually the unit looks like somebody has boiled a kettle in there.

ian window washers seems like your the only one that agrees with me.

I'm not making it up guys it was another customer next door to this one funny enough downstairs window was shut at the time of cleaning was blown but not terrible, as i cleaned with wfp, water trikled down inbetween pane, i poop myself.
left my bill as customer out, in with cheque was a note saying they were cancelling til further notice.

I always tell customers there's no way water can get in(fullstop).

intresting one this,i'm a fitter during the week(need to build my round up so i can sack the day job)vince is right regarding expansion and contraction-the use of washing liquid will quicken the failure of a sealed unit(it reacts with the seal(as most are oil based)and causes the unit to fail)being wrestling with this one for a bit,do i use fairy and get loads of work changing glass or use say unger detergent instead, if anyone is in the leeds area and would like a free lesson on changing sealed units i'm up for it as for where you can get them-most glaziers will make them for you nowadays at very cheap prices around £30 a metre is average-this is a very good add-on to get into fourty or fifty quid profit for an hours work(including a cup of tea is not to be sniffed at)
