I would agree that in your area, a house of that size you could charge a tenner for. In other parts of the country you would not get away with that.
In my area the average price would be around £7-£8.00.
Time taken with tradition method, including pulling up, cleaning and being loaded back up and ready to move on, about 15-20 minutes.
If you had 30 accounts like this in just a single street, and access was easy to all of them, and the customers didn't keep talking to you or offering you cups of coffee
Then you could probably average 4 an hour, but you would have to be going for it.
It isn't often you can be in that sort of position, but with houses of that size you should be able to comfortably do 3 an hour. They are rarely all in the same street, or all next door to one another, so you are going to be loading and unloading your vehicle throughout the day.
But on a full time residential round you are going to have a great many different houses to clean, all of differing sizes, and all sorts of styles of windows, some will be awkward, sloping ground, bushes in the way, narraw paths, difficult parking and so on.
You won't work 8 solid hours per day either, so you can't really say that you will do 4 houses per hour, £10 per house, 8 hours per day (£320
I don't think so uncle!)
The reality is of course far less than that. You should be potentially able to earn £100 a day, many will earn a great deal more than that, equally many will earn a lot less.
I've personally had days when I have gone out and only knocked out £30, I might have been late starting, or gassing to a mate, or maybe just couldn't be arsed
Yet again, using trad methods, the average casement window should take around the 90 second mark to clean. Thats from plonking your ladder up against the wall, to starting to walk back down it.
You experienced guys still using trad methods, try a little time and motion study on yourselves and see
Make sure the window you time yourself on is an upstairs one, has one opening light, one pane about 4ft wide and 2ft 6in high and the other opening casement to be about 2ft wide and 3ft 6in high.
you are not to try and emulate 'Turbo Terry', it isn't a race to see how fast you can do it in, its your standard work speed that you are timing. and don't forget to 'detail' the window and clean the sill either
With WFP, the time taken to clean a window is more like 30 seconds, timewise, on a stand alone account of the size you mention there would not be a lot of difference in the total time taken, about 15 minutes from turning up to driving away.
But as the account gets larger, or the windows are georgian, the WFP really hits its stride.
I talk too much, I only came downstairs to check my mail and take a cup of coffee back to bed
It's cold now (I forgot to drink it cos of doing this post!
)
Gonna make another and have my lie in! It's been a tough old week, what with the bitterly cold weather, so I reckon I've earned the right to get warm and snuggly under the quilt :
The wife has gone to work, so I can't getted nagged to get up and do some work!!
Bliss!
