I had a phone call a few months ago from someone enquiring about window cleaning.
The caller explained that his window cleaner had retired due to ill health and so required somebody else.
He then asked me if I used the "Brush on a Pole" method to clean windows?
To which I replied "Yes for 99% of the properties I clean."
He paused and then said "Well I don't think that will be suitable and maybe i'll continue looking for someone else."
So I gave him the spiel about wfp cleaning windows/frames/sills every visit and H&S aspects etc.
To which he replied "But I don't see how it can be any good, and my old window cleaner said you can't see what you are doing if you are cleaning an upstairs window while stood on the ground?".
I asked him if his windows had ever been cleaned with the wfp method, to which he replied "No".
So somebody who had never had their windows cleaned by wfp and previously used a traditional window cleaner who had never used wfp.
But had still made up his mind that wfp could not do a proper job and couldn't be convinced otherwise.
