Please note: there are tons of references online on the subject of painting (from pros who have been doing it for years). This post is going to be an overview of the steps, mistakes, and successes we used/had.

How much you’ll make owning your own house painting business will depend a lot on how you choose to run your business. There’s no one clear answer to the question of “how much do paint company owners make”, so consider asking yourself a few questions that will allow you to gauge your unique income potential. Will you do all of the work yourself or will you hire workers to pick up some of the slack? How many jobs do you plan to take on? Will you be able to invest in advertising? What is the demand like in your area? What do other house painters in your community charge?
