My husband and I began the remodel of our home in Orinda in 2016. We interviewed five builders and decided to work with Keith and Jeff Stone and their team at Diamond Construction. It was one of the best decisions we have ever made. The work performed on the house was of the highest quality, and the workers were all professional and meticulous. The head forman, Jim was on the site continuously working along side the team demanding the best. Additionally, he diplomatically managed neighbors and traffic issues with the construction trucks. Keith was transparent and efficient with the billing. All invoices were prepared and presented to us with clear tracking of expenses and budget including all supporting documentation. Yes, there were some glitches; the first year had a record rainfall season and some materials were delayed. These and other problems were managed and time adjustments made. The result of our extensive remodel exceeded our expectations. The house is not only solidly built but the workmanship is exquisite. Needless to say, we give our highest recommendation to this experienced and excellent company. It truly was a pleasure to work with Keith and Jeff Stone and the Diamond Construction family.

Diamond Construction is a building team like no other. They bring the entire meaning of the word “Team”to a higher level because of the quality of their work, the quality of their collaboration and ultimately their commitment to the client. Diamond Construction never cuts corners, goes the distance and makes all of us other professionals look good. I love working with them as they not only bring my designs to life, they make them better in every way.

We have now worked with Diamond Construction on several design projects and have only had positive experiences. Jeff and Keith are skilled project managers, keeping communication strong between all project entities and making sure that the projects move forward efficiently. Jeff Stone is very attentive and always appreciative of our work. The team at Diamond Construction focuses on providing quality work for their clients while treating their colleagues and collaborators with the utmost respect.

Diamond performed a major remodel of our Lafayette home: complete kitchen and dining room; double garage, including new slab; doors and hardware throughout; and lots of incidentals.
Working with Diamond was a dream! Their work flow and cost estimates were clear and concise, and spot on. The schedule was extended only a bit by our change orders, and the final invoice was within 1%. Jeff and Keith met with us nearly every day, and involved us in every step.
The subs were timely, reliable, personable, professional, and routinely performed excellent work. They have all partnered with Diamond for many years, and obviously have a lot of respect for Keith and Jeff. We would use any of them again, in a heartbeat.

Diamond Construction is certainly a quality custom home builder with a knack for addressing the specific needs of their clients. We have worked with Keith and Jeff Stone for few years now providing landscape architecture design services and value their desire for a holistic approach to site planning. With their home building talent, passionate energy, and enthusiastic personalities we highly recommend Diamond Construction for those seeking exceptional professional construction services.

We’ve used other contractors before Diamond, but only Diamond after…Over the last 24 years we have worked with Diamond on 4 major projects both inside and outside our home. They always put their client’s satisfaction first and foremost. They are always responsive, knowledgeable, diligent, fair, and trustworthy. They fully disclose cost and don't barage you with unaticipated " change orders." They have wonderful subcontractors. The quality of their work is unsurpassed. They leave the job site clean daily, and their employees feel like part of the family. We look forward to our next project with them.

Diamond Construction holds a class of its own when it comes to integrity, quality and customer care. A family business run by founder Keith Stone and his son Jeff Stone, Diamond consistently delivers beautiful craftsmanship with precision care. The firm’s entire team has long-term relationships in mind with everything they do. If they can’t do it in a way that bears the test of time, they won’t take the job.
While Diamond Construction sets a high bar for quality, they are sensitive to cost and highly skilled at improving design within existing footprints. Keith’s 30+ years of experience helped us transform a 4800 sq. ft. custom 1960’s contemporary home into a gem in line with today’s market. He and Jeff presented creative, affordable and viable solutions to costly conundrums that arose from new code requirements. In the end, they presented a home that was in a class of its own, just like Diamond Construction.
Integrity, quality and service form the backbone of Diamond Construction. What’s truly unique about Diamond is the heart that drives the firm. Across the board, Diamond’s crew consistently hears customers and responds to their concerns. They are compassionate and supportive in tough times, celebrative in times that are good, and always your best advocates for getting a project done well, on time and on budget.

Without any hesitation, we would recommend Diamond Construction. In fact, when we asked others who had worked with Diamond, they all said the same things "We loved working with Diamond and would recommend." Keith and Jeff Stone, owners, held our hands throughout every step of the remodel process and still continue to check in and fix the most minor issues a year after our beautiful home is complete. Keith sat with us through meetings with the architect and as he has a great eye, corrected the architect when necessary, met me when shopping for moldings, windows, doors, fixtures, cabinets, floors, etc - you get the point. As both Keith and Jeff have a great eye for design, they gently and diplomatically led me toward better choices when mine were not quite right - very important when you are making choices for a nearly 7,000 square foot house! One of the most impressive points about Diamond is the fact that they take responsibility for all of their work and for their subs - if something is not correct, they fix it and make it right. Our foreman, Oscar, was exceptional as were all of the men working on our house. Prior to this project we had done many small remodeling projects which almost always left us feeling unsatisfied and upset with the contractors. We will never use another contractor again, Diamond has gone beyond our expectations and they are exceptional.

The Diamond Construction team did a large outdoor living / remodel for us. They have the professionalism of a Fortune 500 business with care and high touch of your favorite high-end shopping destination. They are true to their word and take great care in getting it right, they way you want it, each time. We liked them so much that we started to call them family.

Diamond Construction did an excellent job on our residence. Our site was steeply sloped with several protected trees and the house included many exacting architectural features. The final result was outstanding and Diamond Construction were professional, efficient and always easy to work with. We highly recommend them.

I have worked with Keith Stone and the fine crew at Diamond Construction for over eight years providing structural engineering services for a wide range of residential and commercial projects. It is always a treat to work with Diamond as they are dedicated to providing only the best finished products to their customers. When we work together we are always treated as an equal and important member of the team, with mutual respect and professionalism.
