think all's been said.
simp, was going to suggest trad downstairs.
I started wfp in sept 06.
did most of downstairs trad then gradually went all windows wfp, still do odd kitchen window trad

these are the ones that get the most scruetiny, mrs doing washing up and staring through window.
for me wfp is good for 98% of my work,
If i have too many problems off the custy then i just drop them.
If the windows don't suit wfp then i don't bother.
I've been up and down ladders looking for marks that aren't there, simply because the customer won't be honest and don't like wfp.
yes wfp pole isn't perfect, it won't give good results on windows that are in poor condition.
but there you go choice is uo to window cleaner get ladders off and do or don't bother with

thanks all
Lee.
