Due to the difficulty of concrete finishing, you should only hire a contractor with demonstrated experience. Stamping and coloring of concrete is one of the more sensitive aspects of laying concrete. If it is done improperly, then you may end up with uneven or oddly-colored concrete. This is why you should only consider hiring contractors with a demonstrated knowledge of concrete finishing.

Try to only hire contractors with references. Local references are always the best if you want to learn about the contractor before hiring him or her. Most contractors can project an image of themselves that shows confidence, skill, and experience. However, you can never be completely sure of whether or not you're getting the full picture. When you contact references, you will be learning about the skill, professionalism, and experience of the contractor before hiring.
