wfp overall is faster over the working week.you ll find some jobs your considerably faster and others similar to trad.as for some customers not liking wfp.well ive picked up a lot more than ive lost since going wfp 13 months ago.
you can clean 99% of windows with wfp plus the add on jobs.also those large houses and commercial will become good earners.
the learning curve will be a good few months plus you ll spend a fair bit on equipment and finding what suits you best.
wfp is the best move ive ever made in window cleaning and if your serious about your business then you gotta get a set up and wise up.i do use trad on some work as its easier esp in tight spaces or certain types of windows but wfp is one hell of a tool and is the main tool of choice.
safer,easier,faster and you will earn more money.it really is a no brainer for most work.
