We Take on Construction Projects Other Contractors Won’t
For hillside, tight access, or zero-lot-line construction in San Rafael, we’re the company to call. We have built a reputation for succeeding where others fail. With our extensive experience and equipment, you can count on us for the following and more.
- Tight access projects: We take on jobs in areas with little to no access, using creative solutions like bucket brigades and conveyor belts to move soil when using heavy machinery is infeasible.
- Crawlspace work: Our crews have completed projects in spaces with as little as 18 inches of headroom, proving that no space is too tight for us to work safely and effectively.
- Steep hillside construction: We stabilize and build on slopes where most contractors cannot operate.
- Zero-lot-line properties: We excel in projects where homes are built directly against one another. In fact, we’ve corrected foundation issues on neighboring properties when other contractors failed to account for them.
- Unique site conditions: From jobs restricted to low tides to projects that demand innovative approaches, we adapt to conditions and deliver the results our clients need.
