“Keystone, led by Paul were exceptionally professional, trustworthy and knowledgeable. They were a pleasure to deal with. They worked on a fairly large Kitchen/Orangery project for us which took approx. 5 months to complete, and the work is outstanding. Another differentiator for us was Paul’s contacts in the industry and his excellent advice across a wide range of trades. He also had an excellent eye for what would look good or not. We would definitely recommend Keystone to anyone looking for trustworthy professionals.”
