Got to disagree with Trev here, at least in part.
I think the arguement is flawed to say that you have bills to pay, it's my job and I'm doing it come hell or high water.
As some others have said, if I had a window cleaner and he turned up to clean my windows in the conditions we have experienced of late, then I would tell him not to bother this time.
If he used the arguement that Trevor uses to justify working, and further said something along the lines of, 'I'm only prepared to do regular work, if you are goingto use the weather as an excuse not to have your windows cleaned then you will have to find another window cleaner.'
I'd feel angry and frustrated that I was literally being blackmailed.
If I agreed to his demands, I'd probably drop him at the first opportunity, particularly if I paid him a tenner, and by the time he'd loaded up his van my windows were grubby and dirty again
Now if that is the way I feel, then I am not going to subject my DOMESTIC customers to something I myself would object too.
However; Should a customer come out to me and say, 'No thanks mate, it's going to rain tomorrow.'
When I've turned up on a perfect window cleaning day then I'd probably not bother coming back the following month.
The car wash analogy isn't a good one, if I take my car into the car wash, that is my personal choice, might be different if someone turned up and cleaned my car in bad weather
Commercial work is different, and particularly shops, some are done more than once a week, I'll do those in a monsoon without a qualm, with strict contract work you have to.
Domestic can drift in the winter, that is of course unless the customer wants to stick rigidly to a day or date, in those circumstances, they are done whatever the weather.
On my top end commercial accounts I'll also not risk jeapordising them by cleaning them in really poor conditions, though I will clean them in conditions that I would have second thoughts about on domestic work.
On offices you are often contracted to clean them monthly, but you can usually getthem done in the week you are supposed to get them done in.
