From a Basement Dream to a Full-Scope Contractor

Since 2006, ZLC has grown from residential remodels to demolition, concrete, utilities, and excavation, driven by passion, resilience, and the trust of our clients.

About ZLC Corp

Built on Machines, People & Follow-Through Since 2006

ZLC started in a Walnut Creek basement in 2006 with a small crew and a big vision. When the market shifted, we adapted, completing hundreds of pool removals by 2011 and taking on our first large-scale commercial demolition in 2014. Today, headquartered in Concord, CA, we deliver turnkey demolition, concrete, utilities, and excavation across Northern California, one team, one contract, fewer handoffs, and projects finished right.

Two decades later, our foundation is the same as day one: hard work, good people, and a commitment to do what we say we’ll do.

Testimonials

Trusted by GCs, Owner Reps & Developers

Clients count on ZLC to show up prepared, coordinate clearly, and keep work moving—from surgical demo to full site packages. Most jobs pass first inspection and finish to spec.

ZLC planned the sequence, kept the site clean, and hit every inspection on the first pass. When conditions changed, they adjusted without drama and kept us on schedule. Reliable field crews and responsive office support.

From selective demo to the slab pour, communication was tight and logistics were dialed. One contract for demo, utilities, and concrete meant fewer handoffs and fewer surprises. They solved problems before they showed up on my dashboard.

ZLC delivered exactly what they promised—safe, compliant, and on time. Their coordination with inspectors and utilities avoided delays, and their reporting made it easy to brief stakeholders. One team we can trust on complex, fast-track work.
