A First Choice in Building Since 1959

Learn More About Us

Pacific Systems Interiors has been providing premier building solutions since 1959. We’re proud to be a 100% employee-owned company with strong ties to our union. Every team member is trained, respected, and supported by PSI, making us the most admired and successful contractor for wall systems, finishes, and specialty interiors in Southern California. Our clients come from a wide range of industries, and we are a first choice for many contractors and end users.

Our services include preconstruction, prefabrication, and onsite construction. These services, the heart of PSI’s work, are performed by expert, union-trained team members. We work cooperatively with each party involved to ensure our services are delivered on time and under budget.

Excellence Starts with Safety

We are completely committed to safe work environments. Nothing is more important to us than having our employees and tradespeople return home safely every night. Toward that end, we have a robust safety program, a dedicated safety team, and safety-empowered worksites.

Infection Control Industry Leaders

Explore Infection Control

We understand the importance of infection control for construction projects in occupied facilities. All employees receive a minimum of 20 hours of ICRA (Infection Control Risk Assessment) certification training. Control measures include using negative air machines and an anteroom for changing into Tyvek suits, boot covers, headcovers, gloves, and masks or breathing equipment. PSI has regularly collaborated with epidemiologists over the decades to ensure the highest industry standards in infection control.

PSI’s Radiation Shielding Installation Division is a one-stop shop for all lead-based shielding needs. With decades of experience installing lead-lined walls, doors, and windows, our team has developed a comprehensive, safe, and efficient program that exceeds all regulatory requirements. Whether you need lead-lined drywall for partitions or ceilings in your X-ray department or lead sheets, lead-lined doors, door frames, and windows to protect employees in your energy plant, we look forward to providing radiation shielding installation services to contractors and end-user clients.
