3. Simultaneously provide world class customer service from our field operations to our office administration.

4. Safety & Growth

How we started

It’s in the blood!

The Lambaren family has construction in their blood. Following in the footsteps of their father, Jose "Chon" Lambaren, the siblings have kept up the tradition of hard work, honesty, and integrity. Sticking to these core values has created a tight-knit company culture and top-notch construction projects that have been handed down through generations of satisfied customers.

As time has gone by, more families who share these original principles have become part of our team. This unity of purpose has not only improved the quality of what we do but has also led to impressive growth that's hard to beat.



Who we are

A family-owned business, today EFI successfully preserves family cultures and values while implementing and maintaining corporate principles.

This successful formula has resulted in EFI becoming a full turnkey contractor performing work throughout the state of California and the Western United States becoming the preferred contractor in the industry.


Our future

Promoting growth remains integral to our culture here at EFI. Currently, our workforce includes father-son and mother-daughter teams collaborating harmoniously. This sets the foundation for younger generations to join the EFI family, fostering an environment where individuals craft careers rather than merely occupy positions.
