It may come as a surprise that I agree with squeaky…

I don’t think that squeaky has an ‘unusual’ window cleaning round...

I actually do agree that there are many occasions when a ladder could be used to gain access to Difficult windows…

But here is the twist

WAHR is not about the quality of your cleaning ability.
WAHR is not about can you clean each and every Window.
WAHR is about working safely.
Imagine this; I could speak to my customers and say that it would be ‘safer’ not to use a ladder i.e. not to Work at Height.
Its safer because the likelihood of me falling from Height is greatly reduced if I don’t work at Height.
Would your customers be pleased to know and respect that you are working to certain standards of Safety? Or would they tell you that they didn’t care about Safety (Perhaps some would, but I dare say according to my experience they wouldn’t argue, especially as the Law is on your side).
They know you’re hard working. They know you’re reliable. This isn’t about your personal cleaning standards. Remember this is working in the safest manner possible.
Now revisit your round and but do not ask yourself can I clean ‘Every’ window rather ask yourself could those ‘Difficult’ windows be avoided?
The answer is yes.
