One of the most important things for you to understand about commercial painting is that, generally speaking, no two companies are created equally. All painting contractors do things in their own way and have their own unique approach - which makes sense, considering that what you're talking about is every bit as much an art as it is a science. Having said that, there are a few key qualities that all successful (and trustworthy) commercial paint contractors share that you should definitely be aware of before you choose your next partner.
The Entire Process is Fair - Including the Estimates
Easily the most important quality to look for in a commercial painting contractor is a sense of fairness - the idea that they treat you the way that they themselves would want to be treated. This includes giving you fair, accurate estimates and pricing on all projects up front before the job actually begins. Anytime the estimating process is muddy, you're probably looking at a situation where hidden fees and sudden up-charges are considered "normal" - and that is not a situation you want to be in.
Integrity, Commitment and Professionalism
Another key quality to look for in a commercial painting contractor involves how they operate before they ever arrive at your site to begin work. Not only should they make an effort to hire trustworthy employees who are also subjected to things like drug tests and background screenings, but those employees should also receive quality and continuing education such as “on the job training”. This alone is often the difference between "getting the job done" and "getting the job done properly. Above the industry standard.
They Don't Skimp on Materials
Finally, always be on the lookout of the quality of the paint and equipment a commercial painting provider uses. If a quote seems too good to be true, it probably is - and it probably means that they're using inferior materials to try to save money elsewhere. Remember the age-old saying: "you get what you pay for and anything worth doing is worth doing right."
