I would agree with Ross, there are safety procedures you should follow with the use of ladders if you wish to fully comply with all the legislation, but as I drive around, very few ladder monkeys seem to bother about them. not just us window cleaners either.
Do some research on the forum about WFP, ask loads of specific questions, with the type of work you have, you would greatly benifit with having a WFP.
WFP does have an achilles heel though, and that is frames with oxidized paintwork. But that is something you need to learn of at a later date.
It isn't the be all and end all, you can do a superb job with WFP in a third of the time it takes you with trad methods, but you can also do an awful job too, with great ease
Hard to overstate the safety angle, huge, massive and once you start with WFP you are unlikely to want to climb a ladder again.
I've been going 21 years now, going over to WFP has made a huge difference to my business.........5 grands worth of difference in the first year actually
I still use traditional methods, most days in fact (due to the nature of my particular work) but have only climbed a ladder to clean windows (pointer ladder notwithstanding) on perhaps 3 or 4 times in 12 months.
If you are happy and content to stick with ladders then do so of course, just check out the regs concerning safe ladder use.
But you will most certainly have to compete for work more and more with WFP window cleaners.
Perfect system? There isn't one, each will have their champions, Matt, who has replied to your post has done an excellent posting on a DIY system, so there is that option too.
All the info you could possibly want with regards to WFP can be found here, or over on
http://www.another forum.co.uk/
Most of the major manufacturers also frequent the forums, most notably Ionics and Omnipole, you will find they are all helpful and professional (sometimes they squabble
But thats fun
)
Loads of info about WAHD too, ask Rosskesava, its his favourite topic! Isn't that right Ross
Time to go, I've a wife working as a supervisor in a local Spar shop, 10pm finish for her, I get into enough grief for being on here as it is, if I'm late picking her up cos I'm posting on the forum she won't be best pleased
