They fixed multiple cracks in a stone fireplace with a very large hearth. They did a good job and I would call them again for a similar project. I was afraid there would be dust everywhere and that did not happen. Also, they were able to match the existing cement perfectly so you can't even tell it was repaired. It was always my concern that it would be obvious that it was repaired, but you can't tell at all.The price seemed a little high to me but I was happy with the results. The worker pretty much kept to himself and did his work in an efficient and professional manner.
