Its the insurance companies that don't like ladders.
Don't talk Piffle,
Insurance companies love ladders users, whether they are, WC's, Painters or builders they make a fortune out of us ladder users far more than they will ever make from your association.
Come on guys, you know what David means.
As a recent new-commer to WFP (and relatively speaking; window cleaning in general; three years next March); I honestly think that hardened ladder users should use a bit of common sense and make the move towards getting a WFP.
Not only is it safer; it's quicker and easier.
I can't believe there even is a WFP versus Ladders debate. I still use ladders, but only for around 5% of my accounts. Those where I deem I'm quicker for ladders, or I can't gain access with a WFP.
Educate yourself (see Matt's DIY site (provide a link please Matt)) and then educate your customers with David's WFP explanation letter (available from the documents to upload section).
You can get an entry level set-up for around £600.
In the area I live, I think there's just about more WFP window cleaners than traditional ladder users.
'They' say it's not a 'magic wand'; but it is in many ways.
