I wouldn’t want to clean 3 in a row like that for 30 each Nathan,I’d be losing at least 60 quid.
No wonder some huge window cleaning companies have got 1000s of customers they are all too cheap no wonder they keep there work,clean that from a ladder and ask for 30 quid when you are done we don’t use a ladder but we’ve most of us a lot more expenses nowadays I factor that in to my prices I wouldn’t want it for 30 if I got others up the road for twice that.
