Dear W.,
I can't recommend a company, but we do have a stamped concrete patio. I was not the original purchaser -- it came with our house. I always assumed that the previous homeowner put it in because it was the cheap alternative to pavers. Or, to be fair, maybe because they wanted to do a relatively small area, in a circular shape, and maybe pavers were to hard to make in a rounded pattern. To be honest, if you were visiting us for one time, and were busy doing other things, you might think that it is brick because it is stamped with a brick pattern and stained a reddish brick color. But, most people would know, right away. Plus, with the concrete option, I believe that you will have to paint/stain the concrete if you want it to look less like concrete and more like brick or pavers. I've heard that it can be hard getting a color that you are happy with when picking the stain. If I could do it from scratch, I would go with pavers in an instant. It is a classy, timeless look which is sure to add value to your house. Our stamped brick business is just odd. Good luck with your project!
