Is there a point to make that regardless of prefered technique, Wfp is the future? Modern houses now all have UPVC frames none now a days are being built with lead are they?! WFP lends its self nicely to upvc.
I expect there was the same out cry when people stopped using newspaper and vinegar and used a shamee lol. Not sure if i got that in the correct window cleaning timeline of events, i wasnt there, but you get the point.
When i switched, still 20% trad now. People saw it as a good thing as i was "investing" in my business and was more likely to stick at it. Thats what my custies want someone half decent and reliable. Already had someone today say cleaned them myself, wasnt angry at me, just said i knew cos of snow, rain etc youd be a bit late, so im not reliable all the time

and there more i feel unreliabliity in WF as eqp breaks and water freezes etc but on the whole i would say its faster, safer and more convienient. Any older lot have any shoulder/arm problems from the repeat squeege action? infact poling actually gets my neck so that arguement probably isnt valid for pro WF, as I feel worse after a day!!
Anyway the point im making, is i dont think it will be down to preference it think it will come down to law and insurance.
Insurance quotes will for trad go up and up and up and may altogether ban ladders in a legal sense, who knows?
