Client Testimonials

Diamond Construction

Steven and I first hired Keith Stone almost 30 years ago. He was recommended to us by our architect in San Francisco. We were one of his first jobs as an independent contractor. Not only did Keith exceed all of our expectations but his thoroughness and attention to detail is extraordinary. Since then we have hired Keith for all of our projects. This includes working on three homes for us. He has remodeled extensively and built from the ground up at our home in Napa. We cannot recommend Keith highly enough as he is the most honest and reliable contractor one could ever find. In addition he is a gentleman and a friend. Thank you.

Diamond Construction

Keith Stone, and his crew from Diamond Construction, are to be commended for their work in building our home last year. We could not have been more satisfied with the job they did. Keith has a long-standing relationship with his subs, and they too, are first class. Every call I made was answered within the day. Communication never lacked, which is a vital part of construction and design. We highly recommend them.

Diamond Construction

Diamond Construction has done two jobs for me. A penthouse on Lake Merritt in Oakland and they also did a remodel job on the home we are living in now, which is on Round Hill Country Club in Alamo. The remodel job was a major one- over 3 million plus. Both my wife and myself are very very happy with the outcome of both jobs. They are a first class operation- Very honest and on time.

Diamond Construction

Keith Stone and his team at Diamond Construction are honest, professional, hardworking and build great, solid, beautiful homes. We have used them for two separate projects- new home construction and an addition. Repeat business is common for Diamond Construction and we think that speaks volumes about their integrity in the building industry and quality of their workmanship. We highly recommend Diamond Construction.
