You must know how to estimate INTERIOR and EXTERIOR painting jobs. If you don’t, you won’t make any really good money. And you won’t be able to know HOW MUCH money you are actually LOSING on all your painting estimates and jobs.
Plus, you will not be the highest paid on the job site. Most contractors in all trades way underbid. You don’t have to be one of them. Knowing how to estimate correctly gives you the boldness to go where no man has gone before.
