ABOUT US
Ironwood Construction Company
Ironwood Construction Company is a full-service construction firm serving the San Francisco Bay Area, including the East Bay, Marin, and San Francisco.
As licensed General Contractors (CA License #B444427), we bring both engineering expertise and hands-on construction experience to every project.
We’re known for finding smart, practical solutions to complex building challenges. Our work focuses on small- to medium-sized residential and commercial projects—from new construction and remodels to structural, drainage, and foundation repairs.
Whether you’re planning a second-story addition, updating a kitchen or bathroom, or undertaking a seismic upgrade, we can support the project from engineering through construction.
Our services also include:
- Designing and building retaining walls
- Repairing and strengthening existing structures
- Diagnosing water intrusion, settlement, and foundation issues—and creating effective, lasting solutions
Many of our clients come to us through referrals, drawn to our design-build approach and our collaborative style. We’re especially comfortable working with owner-builders and partnering closely with professional engineers & contractors.
