About Us

Celebrating 15 Years of Service

We are Siller Construction Co., a family-owned business that is built on exceptional customer service and hard work. Over the years, we’ve had the opportunity to get involved in many types of projects related to general engineering construction and to serve numerous repeat clients. Our goal is to deliver high-quality, efficient services that support our clients in accomplishing their projects on time and within budget.

What do we do?

As a general engineering contractor, we perform everything from excavation and grading to erosion control, matting, power line support, substation work, and beyond. We hold an engineering license and have the resources available for small or extensive projects in the northern California region. Our team is made up of seasoned project managers, expert heavy equipment operators and skilled support staff who know the ins and outs of the field.
