I think I have come across every problem window you can have with WFP, but I haven't had that one yet!
I have had a soaked carpet after I had cleaned a half Georgian door, that din't go down very well
so of course I now check the doors carefully on all accounts now, the same with the doors with the letterboxes on
It is always difficult when something like a seal on a window has gone, the water gets in because of the nature of the way we clean the windows, it isn't our fault the seal has gone, but you are on the back foot, and of course the customer will just think you are wriggling and trying to get yourself off the hook, and the more you protest, the worse it looks
Methinks I shall be printing out a leaflet extolling the virtues of Pure Water Cleaning, but shall also cover my a r s e with a disclaimer with regards to seals on double glazed units, and a further note pointing out the fact that windows leaking like sieve's are something else I cannot be held responsible for. To be fair though, I always ask the customer before I start an acount for the first time if their windows are weather proof, and then explain that I will leave out any that let in water.
When I was cleaning windows the 'old fashioned' way, I have had customers try to blame me for scratching their windows, the fact that the painters have been in, rubbing down the windows with sandpaper never seems to hold water with them. Fell out with one big time when she wanted to claim off my insurance for new window panes, told them I would happily see them in court, and I was d a mned if I would submit a claim. they backed down when I handed them a piece of sandpaper and got them to sand down the window frame on the back of their garage-instant scratches-
Gave them my equipment and asked them to try and deliberately scratch the glass, even dabbed it in the dirt, result? not a scratch in sight
Needless to say, I felt smug, they looked stupid, and I lost the acount lol
They didn't get their new windows off me, that was for sure
