An average semi, about 11 or 12 standard UPVC windows will take the average window cleaner around 20 minutes....tops!
Or rather you will do the cleaning quicker, but you have to pull up, pack up, collect and move on to the next one.
3 an hour is easily acheivable, and of these type of houses, if you had them all day long, on a good day you might well knock out about 20 of them.
If your record is 14 houses in one day, I'll bet they are not of the standard, 3 bed semi type, you'll have a mixture, some easy, some larger, some harder.
If you are still saying you have only done 14 standard houses in a day, then you are a bit slower than you could perhaps be.
But ultimately it is how much you are earning in a day, not how many houses you can clean.
Yesterday I cleaned just 5 houses and turned over £120. It would have been more, but the first couple of the hours of the day were taken up with other stuff, should hav e been £35 more, and that would have been just 9 accounts in total.
There are a few out there that can bang out 5 or more houses an hour, but they are the exception and not the rule.
Go watch him in action, tell him to put his money where his mouth is!
