One Firm That Does It All

Design-build General Contractor in The Bay Area

As both builder and design coordinator, we take each project from first sketch to final walkthrough without handing it off. Two decades of Bay Area construction experience across custom homes, whole-home remodels, offices, restaurants, retail, warehouses and HOA facilities means we have usually already solved the problem your project is about to run into. Whether it is a hillside addition in Lafayette or a tenant build-out in Concord, the process is the same: a straight assessment, an itemized proposal, a fixed scope, and a schedule you can hold us to.

Our Clients Say it Best

Rated by more than 30 clients on Google. Here is what they say.

I have several reasons for highly recommending Smith & Son Inc. Our project was the installation of a composite deck over a worn out cement patio. Out of the three quotes we received, Lance Smith not only provided us with a detailed quote quickly, he was the only who followed up to discuss his quote. This discussion clarified our project and saved on the overall cost, putting us within budget. Lance recommended a decking material which we are extremely pleased with. Knowing we were eager to start, Lance found a way to begin our project much sooner than expected. His three man crew was led by a seasoned and experienced foreman, Noe, who checked in with us frequently to make sure we were satisfied. Noe took great pride in his work and was very eager to please. We are very happy with the finished project which exceeded our expectations. We would not hesitate to use Smith & Son again!

As a Real Estate Director with a portfolio that contains both commercial and residential properties, I am always managing construction in some capacity. After using Smith & Son for one project, they have become our go-to contractor for any and all construction needs. They have completed at least 6 major projects for us (not counting minor alterations and repairs) and the work has all been impeccable with all details paid close attention to. In addition to the quality of the work done, Lance is fantastic to work with. He is responsive, proactive, and up-front. Every project has been completed on-time, and, when any issues have arisen Lance has communicated them clearly with a plan already in place to address them. He will provide multiple options for projects and recommendations as to how things could be done better, more efficient, and less costly. Everyone I have interacted with at Smith & Son has been equally as fantastic, whether working in their office or onsite at jobs. I cannot recommend Smith & Son highly enough; you will not be disappointed.

I hired Smith & Son to remodel the home office in our backyard. After getting quotes from several contractors, meeting with Lance was like a breath of fresh air -- he was clear, detail oriented, on top of everything, and took ownership over the project. He cares about quality and is not in the business of squeezing money out of customers -- I feel like he was giving the advice he would give to a friend.

I knew the project was in good hands with him and his team in charge. We had great/easy communication throughout, Lance stopped by to check in on the details, and his team was great. We are really happy with the result and I would hire Lance again in a heartbeat.

If you are deciding between contractors for your project, hire Smith & Son!
