WFP here, is used, when at all, for com work and high work to save cherrypicker costs etc. I see WFP as an alternative method of WCing. Like some people on here say, it's not a magic wand. If it ever replaces trad completely, it will take years and years before that happens.
Before anyone says, I'm too tight to give the money out for WFP, I'd just like to say that I've invested more than 5 grand in my carpet cleaning equipment, so it's not that I don't want to spend money on my biz.
Health and safety means just that,HEALTH and safety. It's not all about falling off ladders, take a look at the physical problems some guys get with WFP. Shoulder or joint problems etc etc. Where's the "Health" bit in that?
