Leak Detection
What is Professional Leak Detection?
A water leak you can’t see is often more damaging than one you can. By the time a hidden leak becomes visible — a stain on the ceiling, a warped floor, or a persistently damp wall — the damage has typically been accumulating for weeks or months. In some cases, the only sign is a water bill that doesn’t make sense, no matter how carefully you check every fixture in the house.
SoCal 1 Plumbing & Rooter locates hidden leaks in supply lines, slab-level pipes, drain lines, and behind walls — without unnecessary cutting, demolition, or guesswork. We find the source precisely, confirm its exact location, and present your repair options with upfront pricing before any work begins.
We handle the full range of leak scenarios: slab leaks beneath concrete floors, pinhole leaks in copper supply lines, leaks registering on your water meter with no visible source, and suspected leaks hidden behind walls, under landscaping, or beneath driveways. Every detection starts with a systematic property assessment — and ends with a clear, confirmed answer about what’s leaking, where it is, and what fixing it will involve.
Starting from $199, leak detection is the step that turns “”something’s wrong”” into a precise diagnosis. It’s also what prevents the alternative: tearing up flooring, walls, or your yard looking for a source that professional detection can locate in a fraction of the time and cost.
Signs You Need Leak Detection
Hidden leaks don’t always announce themselves with visible water. Most homeowners notice something is wrong through indirect signals — a bill, a sound, a smell — long before water becomes visible. If you’re experiencing any of the following, a leak detection inspection will tell you whether a hidden leak is the cause.
Your water bill has spiked without any change in household usage. A sudden or gradual increase in your water bill — particularly when you haven’t changed your usage habits — is one of the most common indicators of a hidden leak. Even a small continuous leak can add hundreds of dollars to a monthly bill over time.
Your water meter continues to run when all fixtures are off. This is the single most reliable home test for a hidden leak. Turn off every fixture and appliance that uses water, then check whether the meter dial or the small leak indicator on your meter is still moving. If it is, water is escaping somewhere in your system.
Warm or hot spots on the floor — particularly on a concrete slab. A slab leak in a hot water supply line heats the concrete directly above the leak point. If you notice an unexplained warm patch on a tiled or concrete floor, it’s a strong indication of a slab-level hot water leak.
The sound of running water when nothing is on. Water moving through a pipe under pressure makes a faint but detectable sound. If you can hear what sounds like running water or hissing from within walls, floors, or the ground — with all fixtures off — a leak is likely.
Wet, discoloured, or soft spots on walls, ceilings, or floors. Discolouration, bubbling paint, soft drywall, or buckled flooring above or adjacent to plumbing runs indicates sustained moisture exposure. By the time these signs appear, the leak has usually been running for some time.
Mould or mildew with no obvious source of moisture. Mould growing in an area with no apparent water source — particularly in wall cavities, under flooring, or in ceilings — often points to a slow, hidden leak providing sustained moisture to an enclosed space.
Cracks appearing in your foundation or driveway near plumbing runs. A sustained underground leak saturates the soil around the pipe and can create voids beneath concrete. If you’re seeing new cracks in concrete near plumbing line paths, subsurface water movement may be the cause.

Process
Our Leak Detection Process
We make solving your Leak Detection hassel-free from start to finish.
Call or Book an Inspection
Call us any time or book online. Describe what you're seeing — high bills, sounds, wet spots, or a spinning meter — and we'll dispatch a technician equipped to locate the source. No guessing over the phone: we assess on-site.
On-Site Property Assessment
Your technician begins with a systematic assessment: reviewing your plumbing layout, checking the water meter, and identifying the most likely leak zones based on your symptoms. This shapes the detection approach before any tools are deployed.
Systematic Leak Detection
Using a combination of pressure testing, acoustic listening, and where applicable thermal assessment, we systematically isolate sections of the plumbing system to narrow the leak to an exact location — without cutting or demolishing anything in the process.
Exact Leak Location Confirmed
Once the leak is located, we mark the precise source and show you exactly where it is and what's causing it. You see the evidence — meter readings, pressure results, or other indicators — before any repair discussion begins.
Repair Options and Upfront Quote
With the leak confirmed, we present your repair options — whether that's a targeted spot repair, a pipe reroute, a section replacement, or a larger scope depending on what we found. Full pricing is provided upfront before any work begins. No surprises.
Repair Completed and Verified
Once you approve the repair, we complete it and verify the result — confirming that the leak has stopped and the plumbing system is operating correctly before we leave. Where applicable, we re-test the meter to confirm zero flow with fixtures off.

Why Choose Us For Your Leak Detection Issues
We are commited to provide the highest quality plumbing service.
From $199 — Clear Diagnostic Pricing
Leak detection starts from $199 — a clear, upfront diagnostic cost that gets you a confirmed answer before any repair expenditure. No open-ended ‘investigation’ fees. You know the detection cost before we start, and the repair is quoted separately after the leak is located.
Non-Invasive — Find It Before Fixing It
We locate the leak precisely using systematic detection methods before any cutting, drilling, or demolition takes place. The goal is to know exactly what needs to be opened up — and nothing more — so the repair scope is as targeted as possible.
Full Scope — Slab, Supply Lines, Walls, Drains
We detect leaks across the full plumbing system: slab-level hot and cold supply lines, wall-run copper lines, main water service connections, and drain lines. Whatever the source, we have the approach to locate it.
Detection and Repair in One Call
We don’t locate the leak and leave you to find someone else to fix it. Once the source is confirmed and you approve the repair quote, we handle it — keeping the process in one place, with one team, and one accountable guarantee.
FAQs
Frequently Asked Questions
Everything you need to know about our Leak Detection before you call.
A slab leak is a leak in a water supply or drain pipe that runs beneath the concrete foundation of your home. Because the pipe is embedded in or under the slab, the leak isn’t visible — water seeps into the soil below or works its way up through the concrete. The most common signs are warm spots on a tiled or concrete floor, the sound of running water with all fixtures off, a persistently high water bill, or a water meter that continues to move when the house is completely shut down. A leak detection inspection confirms whether you have a slab leak and locates it precisely before any repair is discussed.
We use a combination of systematic pressure testing, acoustic detection, and visual assessment to isolate the leak location methodically. By pressurising sections of the plumbing system and listening for the distinctive sound signature of water under pressure escaping a pipe, we narrow the location to a specific point — typically within a very small area — before any surface is opened. The goal is to know exactly what needs to be accessed and nothing more, so the repair is as targeted as possible.
Yes — this is one of the most common presentations of a hidden supply line or slab leak. The most reliable first step is to turn off every fixture and water-using appliance in the house, then check whether your water meter is still moving. If the dial or leak indicator continues to move with everything off, water is escaping somewhere in your system. A leak detection inspection will locate the source. We’ve found significant leaks in homes where the only symptom was a billing anomaly — no visible water anywhere.
Most residential leak detection inspections are completed in one to three hours, depending on the complexity of the plumbing layout and the number of zones that need to be tested. Slab leaks in larger homes may take longer if the pipe runs cover significant distances. We’ll give you a realistic time estimate when you call based on what you’re describing.
Once the leak is located and confirmed, we present your repair options with a clear upfront quote. Depending on the type and location of the leak, repair options may include a targeted spot repair, a pipe reroute to bypass the damaged section, a section replacement, or — for more widespread pipe deterioration — a broader repining assessment. You decide which option to proceed with, and we complete the repair in the same visit where possible.
Slab leak repair cost depends on the repair method: a targeted spot repair through the slab typically starts in the $1,500–$3,500 range; a pipe reroute that bypasses the slab entirely can range from $2,000–$6,000 depending on the pipe run; and a trenchless solution such as pipe lining may apply in some cases. We provide a full, itemized repair quote after the detection inspection — before any work begins — so you have a complete picture of the cost and options before committing to anything.
It depends on your policy and the cause of the leak. Many homeowners insurance policies cover sudden and accidental water damage from a slab leak, but coverage for the detection and repair of the leaking pipe itself varies significantly. Some policies cover the access and repair of the pipe; others cover only the resulting water damage to the structure. We provide full documentation of the leak location and the repair performed — including before-and-after evidence — that you can submit directly to your insurance provider to support a claim.
