Never.
I am geared up for window cleaning. I’m expert at window cleaning. I’m insured for window cleaning. I have all the perfect equipment for window cleaning. I know how to price window cleaning.
I’m not geared up for anything else, and I know I won’t be as efficient at anything else.
If I have extra time available, I’ll fill it with... window cleaning!
If a customer asks for anything else, I have a collection of business cards in the van for various trades people.
great response
this is the simplest way to run a profitable business and best way to get an easier life.
far easier if you want to scale and employ too
i always want to add things and grasp 'opportunities' that 'fall in my lap', but i try to stop myself and simplify the business again and again.
the more different jobs you do, the more problems you have with staff, or trying to get yourself out of the day to day business.
even domestic window cleaning and commercial window cleaning are different jobs. often even need different equipment
saying that, some people want the variety of the additional jobs. window cleaning on its own can be very boring.. if you work on your own and like the variety thats great..
probably not best for your 'business' but as long as you know why you are doing it, and what impact it has, you can do it
