Good painting contractors may have references from local work that was completed in the past few weeks. But great painting contractors will provide multiple references from both recent and past work. References from a year ago or longer show the paint job’s durability and confirm that any necessary follow-up or billing issues were handled correctly. This establishes trust and reassurance that your selected contractor will follow through.
Concrete walls must always be prepared before painting, but in some cases previous finishes will also have to be removed so that paint doesn't peel or chip off. Additionally, special sealants, primers and paints may be applied to ensure concrete's endurance in face of the specific elements. Depending on the wall's condition and exposure to the sun, painting professionals will usually estimate between $500 (~250 sq. ft.) and $2,000 (~1,000 sq. ft.), depending on wall area to cover.
Paint gets more expensive as you go from flat to gloss. The difference is usually around $1 per gallon per sheen upgrade. Flat is the cheapest, then matte flat or eggshell, satin, semigloss then gloss. Paint also gets much more expensive the darker it gets. A white or neutral paint color can be as much as $20 less expensive than a deep base red or blue.
Research the licensing requirements for your area. These laws governing professional contractor work will be different depending on where you live. It’s important to be aware of these laws and what they mean from the outset. Contact the licensing board for your state or district to find out more about what you’ll need to do to get your business off the ground.
