Stephen, we want to thank you for your wonderful work on the major remodeling job that you just finished for us. Since this was our first time doing such a big project- multiple rooms,- we were nervous, as we had heard many horror stories. However, you made us feel safe and taken care of from the start. There were a lot of things that impressed us, like how well you supervised your team. You or your supervisor always made sure that things were done right. Your guys cleaned up every day. And the easy approval from Home Owners Association was such a relief, your help was invaluable. Our friends and family that have seen the work love it, and we were glad that one of them has already contracted with you for a project. Thanks again for everything. We're saving for the next project you guys do for us!
