We are a family owned and operated specialty contractor operating in California since 1978 encompassing two generations. We are amongst the first firms to install Helical Anchor Products for residential underpinning in the U.S. beginning in the 1980’s as an original A.B. Chance certified installer. We continue to conduct business throughout the bay area and beyond blending innovation and creativity to execute our work on new and existing structures. Much of our work involves technically challenging construction in very difficult and sensitive environments.

Sunstone corrects, protects, saves and creates space.

We operate a fleet of equipment using vegetable based hydraulic oils in the performance of the following services:

Sunstone Construction Inc. leverages our years of experience and innovation in the seawall construction and repair business to accomplish the difficult task of addressing coastal erosion on the bluffs and at surf line. We construct seawalls in some of the harshest and most dynamic environments on the planet.


Retaining Walls

Properly engineered and constructed retaining walls are a fundamental element at residential and commercial sites and are a cornerstone of business at Sunstone.


Helical Piers Installation for Foundations and Foundation Repairs

Helical Piers or anchors are deep foundation solutions used to secure new foundations, or repair existing foundations. Because of their design, helical piers offer an easy to install solution in buildings or environments where soil conditions and other factors don't lend themselves to shallow foundations.



Continuing to work with Large and Small Companies, as well as homeowners, Sunstone Construction Inc. has been in business since 1978 as a Licensed California Contractor. We pride ourselves, in being a family owned and operated General Engineering & Building Construction Corporation, as well as being the original A.B. Chance recognized contractor/installer of helical under-pinning, in the United States.

Our focus of construction operations are on challenging projects, usually involving little or no access for conventional construction methods. To excell in this area we typically work closely with:

  • Soils Engineers
