I honestly can’t say enough amazing things about Roy and his team. His level of attention to detail surpasses anyone I’ve ever met (and I work in the design industry). Feel beyond lucky that we had him with us for our last three renovations. The man works tirelessly to get work finished on time and in impeccable condition. He’s also an incredible human. I will be referring him to any and all friends in the future. Thank you Roy & team!!

Roy and Bantry really saved our project. Our previous contractor had had a series of mishaps, and Roy and his team rectified them. He is highly skilled, professional, and has a fantastic crew working for him. I can't recommend him highly enough.
