Leak Detection in Los Angeles, CA

A hidden water leak can cause thousands of dollars in damage before you even know it exists. Slab leaks, underground leaks, and concealed pipe leaks are common in Los Angeles homes due to aging copper pipes, ground movement, and high water pressure. 24/7 Rooter Service provides professional leak detection throughout Los Angeles, CA using non-invasive equipment to locate leaks without unnecessary demolition. Call (213) 281-4751 for fast, accurate leak detection service.

Types of Leaks We Detect

We locate and repair slab leaks under concrete foundations, underground water line leaks in your yard, leaks inside walls and ceilings, pool and spa leaks, irrigation system leaks, and commercial water system leaks. Many of these leaks produce no visible water but still cause mold, foundation damage, and high water bills. Our detection equipment allows us to pinpoint the exact leak location before any cutting or digging begins.

Signs You May Have a Hidden Leak

Watch for these warning signs: a water bill that has increased significantly without explanation, the sound of running water when all fixtures are off, warm or damp spots on floors or walls, cracks in your foundation or flooring, mold or mildew odor without a visible source, low water pressure throughout the home, or a water meter that continues to move when all water is turned off. Any of these signs warrants a professional leak inspection.

Slab Leaks in Los Angeles

Slab leaks are one of the most serious and common plumbing problems in Los Angeles. The city has a large inventory of homes built in the 1950s through 1970s with copper water lines embedded in the concrete slab foundation. These pipes corrode from the outside due to soil chemistry and high water pressure, developing pinhole leaks under the slab. Left unaddressed, slab leaks erode the soil beneath the foundation, cause concrete cracking, promote mold growth, and can lead to structural damage. We use electronic amplification equipment and pressure testing to locate slab leaks precisely so repairs can be made with the smallest possible opening.

Our Leak Detection Process

We start with a whole-house pressure test to confirm a leak is present and isolate which system is affected — hot water, cold water, or sewer. For slab and underground leaks we use electronic listening equipment and ground microphones to amplify the sound of escaping water and pinpoint its location. For wall and ceiling leaks we use moisture meters and thermal imaging to find wet areas without opening walls. Once the leak is located we give you a clear explanation of what was found, where the leak is, and your repair options before any work begins.

Leak Detection for Home Sales and Insurance Claims

We provide written leak detection reports that can be used for homeowner insurance claims, home sale disclosures, or HOA documentation. If you are buying or selling a home in Los Angeles and need a plumbing leak inspection, we provide thorough documentation of any leaks found including location, type, and recommended repair method. Many insurance claims for water damage require professional documentation of the leak source — we provide that documentation on every leak detection job.

Frequently Asked Questions

Question: How do I know if I have a slab leak?
Answer: Common signs include warm spots on your floor, the sound of running water when everything is off, cracks in flooring or walls, and high water bills. A water meter test can confirm if water is escaping even when all fixtures are closed.

Question: Can you find a leak without cutting open my walls?
Answer: In most cases yes. We use non-invasive electronic detection equipment, moisture meters, and pressure testing to locate leaks before any demolition. We only recommend opening walls or cutting concrete once the leak location is confirmed.

Question: How much does leak detection cost in Los Angeles?
Answer: Cost depends on the type and complexity of the leak. We provide upfront pricing before starting any work. In most cases the cost of professional detection is far less than the damage caused by an undetected leak.

Question: Do you repair the leak after finding it?
Answer: Yes. We are a full-service plumbing company. After locating the leak we provide repair options and can complete the repair the same day in most cases.
