Our Story

Built on
Decades of
Integrity.

DLO Plumbing was founded in 1973 by the De La Ossa family and has been a cornerstone of the Nogales community ever since. For over fifty years, we've built our reputation the old-fashioned way — showing up on time, doing the work right, and standing behind every job we complete.

We specialize in both residential and commercial plumbing across Santa Cruz County. Whether it's a new water heater in a single-family home or a full plumbing system for a multi-unit complex, DLO has the licensed expertise to handle it.
