Most Westchester homes were dominated by consistent post-war single-family homes near LAX — 1940s–50s tract homes built for the aerospace workforce, on slab foundations. That uniform post-war vintage means predictable patterns: first-generation galvanized supply lines, aging water heaters, and slab leaks under concrete foundations. So when it comes to water leak detection in Westchester, the realities of these homes shape the work. New Pro handles it from our base minutes away on National Blvd, diagnosing first and quoting a flat rate before anything begins.

We locate first, then fix — no exploratory demolition. Many hidden leaks in Westchester turn out to be slab leaks in slab-foundation homes; when corroded supply lines are the cause, a repipe is the lasting solution.
Our process is simple and the same on every job. One: a licensed plumber comes out and diagnoses the real problem — with a camera or electronic location where it helps — so we’re fixing the cause, not guessing. Two: you get one flat-rate price in writing that you approve before we start; no hourly clock, no surprises. Three: we do the work cleanly and stand behind it. We’re family-owned since 2010, licensed and insured (CSLB #974600), available 24/7, and fully bilingual — and we leave your home cleaner than we found it.
The best water leak detection in Westchester finds the source without guesswork or needless demolition — we pinpoint it, then fix exactly that.
Affordable water leak detection saves money by avoiding torn-up walls and wasted water. We quote detection and repair flat, in writing.

Because Westchester homes share an era and a builder, the plumbing problems are remarkably consistent street to street — which means we often recommend the same proven fixes, and many owners now choose a full repipe over patching the same lines again and again. For water leak detection specifically, that means pinpointing the source before opening a wall or slab keeps the repair small and the damage minimal. It’s also why this page is part of our full Water Leak Detection service and our Westchester plumbing coverage — a water leak detection problem is rarely isolated from the rest of the home’s plumbing.
For local water and permitting questions, the LADWP and the City of Los Angeles are the authorities; for national drinking-water standards, see the U.S. EPA.

Westchester was built out in the 1940s–50s for the aerospace workforce, so the homes share an age and construction style — and therefore the same end-of-life galvanized lines and slab-foundation issues. We see the same fixes repeat across the neighborhood.
Electronic and acoustic equipment plus pressure testing let us pinpoint the source first, so any opening is small and targeted.
That’s exactly when leak detection pays off. Hidden slab or supply leaks are common in Westchester; we’ll find it.
