Newport Beach runs its own municipal water system, with interconnects to Irvine Ranch and Mesa Water District supplies. The water itself is fine. The problem is what happens inside walls and slabs where decades-old copper and galvanized lines have been breathing ocean air through vents, crawlspaces, and attics. Pinhole leaks multiply, pressure drops room by room, and patch repairs turn into a subscription you never signed up for.
When Repiping Beats Another Patch
One pinhole leak is a repair. Three in two years is a system failure in slow motion. Whole-home repiping replaces every aging supply line with new pipe in a planned, single project — instead of opening walls one emergency at a time. Most repipes finish in days, not weeks, and because we route new lines thoughtfully, the drywall patches are small and contained.
For coastal homes we typically recommend PEX. It doesn't corrode, it flexes instead of bursting, and salt air means nothing to it. The result is stable pressure at every fixture from Balboa Island cottages to Big Canyon estates, and an end to the drip-bucket era.
Finding Leaks Before They Find Your Flooring
Pinhole leaks love to hide — inside walls, under slabs, above ceilings — and by the time water shows itself, the damage is already spreading. Our slab leak detection uses acoustic listening and thermal imaging to pinpoint the exact spot, so we open a square foot of drywall instead of demolishing a room to go looking.
That precision matters in homes where the finishes cost more than the plumbing. Whether it's a 1960s ranch in Dover Shores or a remodeled kitchen in Eastbluff, we find the leak first and cut second.

If you're patching leaks more than once a year, it's time to talk about a repipe.
Frequently Asked Questions
**Why do Newport Beach homes get so many pinhole leaks?**
Salt-laden ocean air accelerates corrosion on copper piping, especially in vented attics and crawlspaces where air circulates freely. Combined with naturally hard local water attacking from the inside, copper walls thin until tiny pinholes open — often in clusters along the same runs.
Is PEX or copper better for a repipe near the ocean? PEX, in most cases. It can't corrode, so salt air and aggressive water don't affect it, and its flexibility means fewer joints — fewer joints means fewer future failure points. Copper still has its place for exposed runs, but inside walls near the coast, PEX wins on longevity.
How disruptive is a whole-home repipe? Less than most homeowners expect. We work room by room, keep water on overnight whenever possible, and most homes are fully repiped within a few days. Wall and ceiling patches are kept small, and we leave each work area broom-clean daily.
The city is replacing water mains in Corona del Mar — does that fix my pipes? No. The city's main replacement program upgrades public mains in the street. Your home's private supply lines — from the meter inward — are your responsibility and aren't touched by the project. If those lines are failing, only a repipe fixes them.
