"Tony did a major renovation on a difficult site for me. The whole process was fun, and we couldn't be happier with the outcome, which is largely due to Tony's attention to detail, diligence and the fact that he is a down to earth nice guy who is easy to get on with. I fully recommend Tony and am happy to provide verbal references."

"Tony has been my go-to builder for several years now. Being a tradesman myself I look for high quality workmanship and honest pricing. Tony takes ownership of the project from start to finish, he is easy to communicate with, and his team are easy to have around. I highly recommend Buchanan Renovations."
