yes
although i know someone who subs me to clean insides trad.
However its not that they can't its just they can't be bothered and earn more money per hour using wfp exclusively.
A lot of people just start up with WFP, and know absalutely naff all about the window cleaning trade in general!!
They see a water fed pole in operation and think that looks easy.
I had a lad work for me back in 2005 and he said he had experience, he didnt last the first day!!
he then told me he thought it was very easy, to which I replied if it was that easy, don't you think EVERYONE would be doing it.
I told him WE make it look easy as we do it day in day out.
