Industry Testimonials

I have worked with Keith Stone for over 30 years. During that time he has constructed both residential and commercial projects designed by my firm. Diamond Construction excels in several ways. Keith takes great care to ensure that he satisfies the customer, he listens carefully to the customer’s desires. He strives for, and creates, top quality construction results. His employees, and the sub contractors that he employs, share his desire for quality construction. Keith researches solutions, so when the inevitable challenge during construction appears he provides valuable suggestions for solutions. I highly recommend Diamond Construction.

I have had the opportunity to work on many projects with Diamond Construction over the past 21 years. From the highly experienced crew to the unwavering integrity of management, I could not ask for a better partner in the construction process. I find that instead of the typical stress-filled construction environment, working with Diamond is always pleasurable and a rewarding experience for myself and a hassle-free, highly professional project for the client. The entire crew is not just knowledgeable in construction but is constantly courteous and considerate of the clients and others on the jobsite. They go out of their way to make the whole process as invisible and innocuous as possible.

I always look forward to working with Diamond for I know I can spend more time on Design and less time on detailing and directions. They know their craft and they do it well.

  • Dennis A. Giacovelli

I have had a varied and fulfilling career as an architect and much of it as the principal in charge of design. During a great deal of that time, I had the enjoyable experience of observing and working with Keith Stone and his company. Foresight, honesty, integrity and competency are the benefits that Keith Stone brings to a project when he is made part of the construction project. This is to say, that his experience and talents start to contribute to a project at whatever point he enters. Many of our projects included with his involvement before a line was drawn as a feasibility team member in site selection, construction cost budgeting and to construction logistics.

It is without question that I refer Keith Stone and his company to any prospective client for a contractor that will bring value and order to a project. And on top of that he’s a nice guy.

While I cannot remember exactly how long we have been working with Diamond Construction I can say that it has been at least 8 years. Creegan + D’Angelo Engineers (C+D) has a very long history of providing civil and structural engineering services to the home building community in the bay area since 1956. Diamond Construction stands out as one of our finest home builder clients with a very loyal and qualified staff of project managers and skilled workers. Most of the engineers in my office have fond memories of site visits to the job sites run by Keith and his crews.

When Keith Stone or one of his architect/designers such as Dennis Giacovelli calls us to discuss a new project it is always with enough time to have participation in the early phases of the project. We will generally discuss the schematic design and look at various options with the intention of arriving at decisions that will give optimal results to the ultimate client, the homeowner. With all Diamond Construction projects C+D appreciates our role on a team of professionals from the preliminary design through the design development phase and then to the construction phase and final inspection. Keith is always diligent and strives for perfection in every aspect of the projects we have had the pleasure of working on. We look forward to working with Diamond Construction for many years to come.

In reflecting, I must admit that when I first met and began working with Keith Stone on a home in the Oakland Hills, I did not fully comprehend his choice of names for his construction company. However, having had the opportunity to collaborate on many projects over the years, I now fully understand and realize that Diamond was the most appropriate name he could have selected. Keith Stone has consistently shown a brilliance of insight, an assurance of value and a commitment to fine quality in his building. Further, in his dealings with his clients, team and associates, he has always demonstrated in his person a rare integrity and honesty- words and concepts that are often overused but in this case most appropriate.

It has been my great privilege to work with and learn from Keith and his team.
