Between the costs of paint, materials, tools, accessories, labor, gas, taxes, insurance, and more, learning how to bid a painting project accurately is no simple task and takes some serious strategizing!
As a professional painter, job costing is generally one of the more difficult skills to master. After all, biding a new project accurately can make or break your margins.
In this article, we will review in detail the steps required to accurately bid your next interior and exterior house painting project. Even experienced estimators can walk away with some valuable tips from this post!
Why Is Estimating a Paint Project So Difficult?
Before you started painting, you probably thought it would be simple to bid on a job and figure out the cost to paint. Just do a few quick measurements, get the square footage, calculate the labor cost, and add a little extra on the top as your markup. Right?
Well, not so fast. Estimating costs for a painting project takes intelligence, precision, knowledge, and a fair bit of know-how, which oftentimes is easier said than done.
In reality, every painting project you bid will have a unique set of challenges. No two projects are alike because you complete the work onsite. Plus, your cost to paint interior or exterior surfaces is always going to vary based on labor, which is dependent on the overall simplicity or complexity of a job.
While there’s no “one size fits all” approach to estimating your cost to paint, being as accurate as possible is always in your best interest. It makes you look professional, increases your chances of getting the job, and lowers your risk of losing money on the job.
