Hi Adie,
Pro's - You are ya own boss, the work is rewarding and you can earn good money if you stick at it, you work in cash most of the time and the longer you stick at it the easier it becomes. New work is always available, overheads are relatively low. Once established word of mouth takes over and your reputation grows. Opportunity to get other work for wet weather, gutters, fascias etc... Generally if you can hack it the work is rewarding and fun and the summer brings lots of wonderful opportunities to admire the local scenery, if ya get my drift!!
Con's - Stigma of being a window cleaner despite we are a good bunch really and earn good money!! Bloody hard work, every house has about 5 upstair windows, climb a ladder 5 times a house 30 - 40 times a day and ya know about it. Rain!!! Cold in winter!!! Collecting in the evenings!! Make sure you are fully insured for YOU and the business, god forbid you fall off your ladder or worse still go through a conservatory roof you need peace of mind to know you and the customer will be taken care of! Don't be a cowboy and risk it, it is really not worth it!!
Wish you the best of luck, any specific help feel free to ask, if can help you i will, my email is
