Our Story
Three generations below the surface.
Woolworth Construction LLC was founded in 2025, but our connection to underground utility construction goes back generations.
1960s
Where it started
The Woolworth family’s connection to underground utilities began when our grandfather entered the industry after serving in the United States Navy during World War II. His discipline, work ethic, and integrity established the standards that would be carried forward by the generations that followed.
1986
The next generation
Our father continued the family tradition, building decades of hands-on experience and a reputation for craftsmanship and reliability throughout California.
2025
Woolworth Construction LLC
Today, Woolworth Construction LLC carries that legacy forward as a family-owned and operated company focused on underground utility construction throughout Southern California.
The company may be new.
The experience isn’t.

More than putting pipe in the ground.
