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).
