Again I’m not knocking you or anyone but if someone has a good window cleaner they hang on to them 9-10 it’s not the money really,I use a certain builder and he’s not cheap but I won’t use anyone else he does the job properly and thoroughly.
Look at how you clean the windows and what type of jobs they are certain houses-jobs it doesn’t matter how good you are having clean windows isn’t the be all and end all find customers that think it is,I won’t take on certain jobs if I think nah they’ll have it done a few times then sack me off learn to suss em on the doorstep when you first take them on I’ve had customers for decades.
