after many years of a ladder only, i decided to add wfp to my kit - find some jobs better trad and some wfp.
went on here for tips and info.
wfp letter - not a single customer was bothered, they did read it and understood the workings tho.
first cleans - just cleaned each window a time - frames then glass, not a single prob from any jobs so far.
only using xline trolley at mo with new alloy hydra poles.
finding that it isnt any quicker - the cleaning bit is a little quicker but with having to set up the pole and mess around with hose etc it takes longer.
