Our Philosophy
A higher standard, held quietly.
For nearly two decades — since 2006 — New Horizon Plumbing has brought a builder's precision and a craftsman's patience to homes across Los Angeles. Licensed as both a general building and plumbing contractor, we hold every job to one measure: work we'd be proud to leave exposed.
What We Do
The Work
Residential plumbing at the level of finish carpentry — clean, considered, and guaranteed.
Tankless Water Heaters
Design, installation, and flawless manifold work for endless hot water and a smaller footprint. Our signature craft.

Copper and PEX repipes that replace aging, failing lines — installed to last decades, not years.
Water Heaters
Tank and hybrid installation, repair, and replacement — sized correctly the first time.
Drain & Sewer
Camera diagnostics, hydro‑jetting, and trenchless sewer repair that spares your landscaping.
Leak Detection
Precise, non‑destructive location of hidden leaks — found and resolved before they cost you a wall.
Whole‑Home Water Treatment

The Signature
A specialty in tankless.
Endless hot water, a fraction of the space, and years more life than a tank — when it's installed correctly. Most aren't. We treat the manifold like millwork: every line measured, every joint clean, every unit balanced. The result is a system that performs beautifully and reads like a piece of craftsmanship.
From a single unit to a cascaded bank for a large estate, tankless is the work we're known for.
Here's what most homeowners are never told: a tankless heater needs to be professionally descaled and serviced roughly every eighteen months. Los Angeles' hard water leaves mineral scale on the heat exchanger, and left unchecked it quietly steals efficiency, voids the manufacturer's warranty, and shortens the unit's life.
— Scheduled descaling & full system flush, on time, every 18 months
— Protects your manufacturer's warranty and peak efficiency
— Multi‑point inspection of valves, venting, and connections
— Priority scheduling and preferred‑client pricing
We keep the calendar so you never have to. Enroll once, and your system is cared for for life.
I started New Horizon on a simple belief: that plumbing done right is a craft, not a commodity. For nearly twenty years I've installed, repiped, and cared for homes across Los Angeles with my own hands — and I still walk every job myself.
When you call us, you don't reach a call center. You reach me — and a standard I'm proud to put my name on.
