Ian,
For the past three years, February always used to be my worst month for morale.
By this time you've spent Nov/Dec struggling to meet the demands of providing Christmas for your family and then struggled again to cover the bills in Jan.
By February you're feeling burnt out and have had enough of the dark, cold, damp dreary days!
However for me, this year is different; not so much of a struggle; hardly a struggle at all because work is really starting to pay!
So stick with it, mate;come up with some 'plan' to increase your income; Spring is just round the corner and remember that there's some people earning a good income from window cleaning. If they can do it, so can you.
And when it comes to giving quotes and putting your prices up:
i charge around £5 to £6 for a 3 bedroom house is that ok,as i feel like i am riping peolpe off if i charge more
As long as you quote your price and frequency are up front; do a good job; and they agree to your terms and conditions, you're not ripping anyone off.
However, you may do your customers a diservice by being too cheap; then 'jacking it in' and not turning up ever again.
They may well have been prepared to pay a lot more for a good, regular honest 'Joe' window cleaner.
Spring's round the corner and all those 'B list jobs' that other window cleaners have dropped during the rainy weather and shorter working days could soon turn into your 'A Jobs'; if you price them well enough.
