About Us
About L.E.D.R. Corp
Long-Standing Reputation
For more than 30 years, L.E.D.R. Corp has built its name on concrete work across Southern California. Much of our business comes from past customers who recommend us to others.
Proven Project Record
We have completed projects for public agencies and general contractors, from city road work to school district jobs. Each one is built to the standards the job calls for.
Repeat Customers
Many of our clients come back for their next project. They return because the work holds up over time and every job gets finished, no matter what it takes.
Hands-On Leadership
Owner Walter Alvarado stays involved in daily operations and coordinates projects himself. He quality checks every job before it is turned over to the client.
Our Story
For more than 30 years, L.E.D.R. Corp has handled residential, commercial and municipal concrete work, from structural concrete and decorative finishes to large infrastructure improvements.
The company is named after its four founders. When they retired, they handed the business to Walter Alvarado, the employee who had been most involved in their work.
Walter has led L.E.D.R. Corp since 2017. He is still on the job every day, running operations and coordinating each project from start to finish.
