I did one for a few months where i had to get step ladders off to clean 3 velux windows, it took longer to do that than the rest of the windows on the house. Had another with 1 velux that was so high i had to use a 39ft pole off a step ladder. Ive got one at the minute where i clean the entire house then go to the van drag the ladders out to farse about cleaning 2 velux for an extra 2 quid. There was another one where i had to stand on a tramploline, another stand on the road, another i stood in a field lol. I remember one customer i struggled my arse off with for months to clean this one awkward horrible velux at 39ft extension doing it blind backed up against a fence. In the end she sacked me because the velux wasnt being cleaned properly
why didnt i just say no lol
The moral of the story is you shoot yourself in the foot buying extra gear and wasting your time and end up being less profitable out of your need to please the customer.
Gotta learn to say no and either leave those windows or find an easier job!
