Coronado's island salt air and many historic, older homes corrode copper piping over time, making slab leaks one of the most common plumbing problems on the island.

Coronado's island setting and blend of historic and custom homes make it a hot spot for slab leaks.

As a proud provider to Coronado's Navy community near Naval Air Station North Island, we offer a military discount, and every repair is backed by our 1-year workmanship warranty.

Straight answer: your homeowners policy almost never pays to replace the leaking pipe itself — that cost falls to you. What a covered policy can pay for is locating and accessing the leak (the tear-out and put-back) and repairing the resulting water damage — drywall, flooring, and cabinets soaked by the leak.
The one thing that decides almost every claim: the loss has to be sudden and accidental. A leak that's been seeping for months reads as neglect and gets denied — and the moment mold appears, coverage usually disappears with it. That's why speed matters more than anything: the faster we pinpoint and stop the leak, the stronger your position. We document our findings clearly so you have what you need to file — see our insurance claim reports. Always confirm specifics with your own insurer.
A single hidden leak can waste thousands of gallons a year. The EPA WaterSense program estimates household leaks account for nearly 1 trillion gallons of wasted water nationwide every year. With San Diego water rates among the highest in the state, fast leak detection in Coronado pays for itself.
If you suspect a leak, check your meter through the City of San Diego Public Utilities Department, and review conservation resources from the San Diego County Water Authority. Then call Tri Express Plumbing to pinpoint and fix the source — fast.

Leak detection in Coronado typically starts around $295 for an electronic diagnostic, with slab leak location from about $350 — often credited toward the repair. Tri Express Plumbing provides upfront pricing before any work begins and pinpoints the leak with no demolition to your floors or walls.
Coronado's island setting and many historic and older homes make slab leaks one of the most common plumbing problems in the area. Salt air, bay humidity, and San Diego's hard water corrode the copper supply lines running through the slab, leading to pinhole slab leaks. We pinpoint them precisely before any concrete is cut.
We use non-invasive electronic and acoustic equipment, pressure testing, and thermal imaging to locate the exact point of a slab leak under your foundation. This protects the hardwood, tile, and custom finishes common in Coronado homes by keeping any repair small and targeted.
Usually not the pipe repair itself — that's the homeowner's cost. What a covered policy typically pays for is accessing the leak and repairing the resulting water damage (drywall, flooring, cabinets), and only when the leak is sudden and accidental. Slow, long-term leaks are commonly denied, and once mold develops, denial is near-certain — which is why we respond same-day to pinpoint and stop the leak fast. We document everything clearly so you have what you need to file. Confirm specifics with your insurer.
