Hello Leigh,
Go for it bud, especially before you get the 'kids' and all of the trimmings.
I have recently started myself, though i did used to go and do a bit when i was 18/19 yrs old, so i sort of remembered what needed to be done and not a great deal has changed with traditional cleaning.
I'm 33 now and have started a MCSE (Microsoft) course which takes roughly 1-2 years so i wanted to find a job which could cover my bills and give me plenty of flexible time to study.
Window Cleaning is perfect for that.
I started with nothing about 6 weeks ago, i bought a roof rack, ladders and all of the gear that i would need and off i went knocking doors.
In my first couple of weeks, i did the customers houses there and then - i think i picked up about £170 worth of regular work in no time at all.
Also dont be put off by window cleaners already in the area, you will find that they don't clean everyone, some of them will have a full quota of work and wont be looking to take on any more. I have about 7 houses in a street which already had a window cleaner, just keep on knocking.
I sent out a couple of emails 2 weeks ago and found some work which was for sale not too far from me. I paid £200 for just over £300 of regular work which was a great bargain for me. The window cleaner was a good bloke and i cleaned them all and introduced myself to all the customers before paying him.
So in 4 weeks i managed to get myself £500 a month of regular work and thats just the start.
The jobs that i paid for are not brilliant and they take a bit longer than i would like, but at the moment i'm just trying to build an income up and i'm very happy with the way its going.
My own work that i price for, i am working on £15-£20 an hour and i seem to be hitting that mark, i've been out today and i did just over 3 hours for £51 - i also do realise that i'm still quite a bit slow and can pick the pace up a bit further down the road.
I've got a couple of hours to do tomorrow and then i've got a week off to try and build some more, i think once i've got a full month i will be looking to comfortably do about £80-100 a day.
There's no reason why you can't do it as well Leigh, unless you're scared of heights and are rubbish at cleaning windows that is.
Carl.
