We've been working with Jimmy for over 10 years. He came highly recommended from a friend and we're so glad to have found him. He consistently does beautiful and meticulous stonework. Over the years he has completed a brick chimney on our home, stone driveway, stonewalls, patio, bluestone steps and walkways and a gorgeous pizza/fireplace. He recently expanded our patio and it looks as though it was always there. If you are looking for an expert mason Jimmy at Gemstone is your guy!
