Slab Leak Repair in Van Nuys — Trusted Since 1989

If you own or manage property in Van Nuys, you already know the neighborhood’s housing stock tells a story — rows of two-story apartment buildings and single-family homes built throughout the 1950s, ’60s, and ’70s, most of them still running on their original galvanized or early copper pipe systems. Those pipes are now pushing 50 to 70 years old, and when they begin to corrode or shift under a concrete slab, the damage can be swift and expensive. Slab leak repair in Van Nuys is something EZ Plumbing handles regularly, and we understand the specific pressures facing property owners in this part of the Valley.

A slab leak happens when a water or drain line running beneath your home’s concrete foundation develops a breach. In Van Nuys’s older multi-unit rentals — particularly along corridors like Oxnard Street and the blocks surrounding Van Nuys Boulevard — galvanized steel pipes have had decades to rust from the inside out. The result is pinhole leaks that hide under your slab until you notice warm spots on the floor, a water bill that keeps climbing, or the faint sound of running water when every faucet is off. Don’t wait. Left alone, these leaks erode the soil beneath your foundation and can cause structural settling.

EZ Plumbing has held a California C-36 Plumbing License (#583868) since 1989 and has worked in Van Nuys long enough to know what these buildings are dealing with. We use non-invasive electronic leak detection to pinpoint the break before we ever touch the slab — saving you unnecessary demolition and keeping your tenants or family as undisturbed as possible during the repair process.

Why Van Nuys Properties Are Especially Vulnerable to Slab Leaks

The combination of aging galvanized pipe and the San Fernando Valley’s expansive clay soils creates a uniquely challenging environment. Clay soil swells when wet and contracts during dry stretches — and Van Nuys gets both. That constant ground movement puts lateral stress on pipes that are already thinning from decades of mineral buildup and internal corrosion. In multi-unit buildings, the problem is compounded: a shared water main or sewer lateral that serves six or eight units puts significantly more pressure and wear on underslab lines than a single-family connection would. We frequently get calls from property managers who discovered a slab leak only after a ground-floor tenant complained about buckling laminate floors or a musty smell that wouldn’t go away. Slab leak repair in Van Nuys for multi-unit properties also raises questions about shared infrastructure responsibility — something our team can help you document and navigate.

What to Expect from EZ Plumbing’s Slab Leak Repair Process

Every slab leak repair Van Nuys call starts with a thorough diagnostic. We use electronic amplification equipment and thermal imaging to locate the exact failure point without guesswork. Depending on what we find, repair options typically include direct-access spot repair, pipe rerouting through walls or ceilings to bypass the damaged slab section entirely, or full repipe when galvanized lines are too far gone to patch reliably. For older Van Nuys apartments where galvanized supply lines are widespread throughout the building, we often recommend a full repipe consultation at the same visit — it can prevent the next slab leak before it starts. We’ll walk you through every option, explain the tradeoffs honestly, and give you a written estimate before any work begins. Slab leak repair in Van Nuys doesn’t have to mean tearing your property apart — with the right tools and experience, it can be clean, fast, and done right the first time.

Frequently Asked Questions About Slab Leak Repair in Van Nuys

My Van Nuys apartment building was built in the 1960s — does that mean my galvanized pipes are likely to fail under the slab?

Almost certainly, the galvanized steel pipes in a 1960s Van Nuys building are in the late stages of their service life. Galvanized pipe typically lasts 40 to 70 years, and internal rust buildup accelerates failure at joints and bends — exactly the spots most likely to develop slab leaks. If you haven’t had a professional inspection in the last few years, now is the right time, especially if water pressure has been dropping or you’ve noticed discolored water from lower-floor units.

As a property manager, how do I handle a slab leak when it’s unclear whether it’s on a shared lateral or inside an individual unit?

This is a common dispute in Van Nuys’s dense multi-unit housing. The general rule in California is that the property owner is responsible for all plumbing up to the point where it connects to the city main — including shared laterals. EZ Plumbing can perform a camera inspection and produce a written report that clearly identifies where the leak is located, which is invaluable if you’re coordinating with your HOA, an insurance adjuster, or a neighboring property owner over repair costs and liability.

Will you have to break up my entire floor to fix a slab leak in my Van Nuys home?

Not necessarily. Our electronic leak detection equipment lets us pinpoint the breach to within inches before we open anything. In many cases — especially when the damaged section is accessible from a wall cavity or crawl space — we can reroute the pipe entirely without major concrete demolition. Even when direct slab access is required, we target only the specific area of failure rather than making broad cuts across the floor.

How much does slab leak repair in Van Nuys typically cost, and does homeowner’s insurance cover it?

Repair costs vary depending on the pipe type, leak location, and whether rerouting or spot repair is the better solution — but most residential slab leak repairs in Van Nuys range from a few hundred dollars for a simple accessible repair to several thousand for complex rerouting in a multi-unit building. Many standard homeowner’s insurance policies cover the cost of locating and repairing the leak itself, though they may not cover consequential damage like flooring replacement. We recommend calling your insurer before work begins, and we’re happy to provide the documentation they typically require.
