We had Rocky Mountain concrete Specialists do a back patio for us about 10 years ago. It still looks great. 4 years ago we had them back to add a front porch and wall and a side walk from the driveway to the back yard. Again great work. Some of our neighbors have patterned concrete work as well, but these contractors cut corners, and there is stain in places there should not be, and they did not clean it up well. Ours looks perfect.
