Pipe Leak Repair & Leak Detection in Paramount, CA
Find It Without Tearing the House Apart | Slab Leaks · Copper · PEX · Main Water Lines | CSLB #1051553 | Se Habla Español
A leak you can see is a repair. A leak you can only hear, smell, or pay for on the water bill is a search problem first, and searching with a sledgehammer is how small leaks become big remodels. Ser Plumbing finds hidden leaks with testing and inspection tools, shows you the evidence, and opens walls or floors only where the fix actually is.
Then you get the same straight framing we bring to everything: repair the spot, reroute the line, or, when a pipe system keeps failing on schedule, the repipe conversation. One leak rarely justifies panic. A pattern of them deserves a plan.

The Problem: Why People Call
Six symptoms cover almost every leak call. Each one points somewhere different, and each one is findable.
What’s Covered
Leak detection
Pressure testing, meter isolation, zone-by-zone shutoff work, and inspection cameras narrow a hidden leak to a tight location before anything is opened. You see the evidence, and the access cut happens where the leak is, not where a guess was.
Slab leak detection and repair
Location first, then the three-path decision: open the slab and repair the spot, reroute the line overhead through walls and attic, or fold the failure into a repipe when the system’s age justifies it. Each path is priced in writing so the choice is yours. Repiping →
Copper and PEX pipe repair
Pinhole copper repairs, fitting failures, and PEX repairs done with proper materials and the right transition fittings where metals meet, so the repair does not seed the next failure.
Main water line repair and replacement
The line from the meter to the house: located, excavated or trenched as needed, repaired or replaced, and pressure-verified. Whole-house pressure loss and wet front yards usually end here.
High water pressure: the quiet leak factory
Incoming street pressure in parts of the LA Basin runs well above the 50 to 80 PSI a residential system is designed for, and a worn-out pressure regulator lets all of it lean on every joint, valve, and supply line in the house around the clock. We test pressure as part of leak visits because chronic over-pressure is the hidden author of banging pipes, weeping fittings, and repeat pinholes. When the regulator is the culprit, replacement is routine, typically completed in one visit, and it protects every repair we just made.
Burst and emergency leak repair
Active flooding stabilizes first. Shut the main, then call; the repair decision comes after the water stops. Emergency plumbing →
Smart leak detection systems
Whole-house monitors with automatic shutoff catch the next leak while it is still a puddle, and some insurers offer discounts for them. We install and configure them as an add-on to any leak repair.
Whole-house repipes have their own page → Repiping
Drain and sewer line leaks (waste lines, not supply) → Sewer service
Roof and irrigation leaks: not our trade, and we will say so honestly if that is what we find
Pricing
Leak work is quoted from findings, and here is the range the work typically falls in:
What moves the numbers: how deep the leak hides, what sits on top of it (tile, hardwood, concrete, landscaping), which repair path you choose, and whether the surrounding pipe justifies repair or replacement. Detection fees fold into one picture: find-it and fix-it is quoted as one written decision, not two surprises.
Standard labor discounts apply, and financing is available for qualifying larger repairs through our booking platform.
Why Ser Plumbing for Leaks
We prove it before we cut
Demolition is the last step, not the first. Meter isolation, pressure zones, and disciplined elimination mean the wall opens where the leak is.
Honest enough to find nothing
Sometimes the moisture is not the plumbing: an appliance, a shower pan, a roof path. When that is the verdict, you hear it plainly and keep your money for the right contractor.
The three-path decision is yours
Spot repair, reroute, or repipe: each priced, each explained, each with its expected lifespan. We recommend; you decide.
Repairs that do not seed the next leak
Proper materials, correct fittings at every transition, pressure verification before we leave. A leak repair should end a problem, not schedule one.
Documentation your insurer can use
Photos, findings, and a clear written narrative of cause and correction. Coverage calls belong to your insurer; evidence is how you make your case.

Ask us directly ↗
My water bill suddenly spiked. Is it a leak?
How do you find a leak without tearing up the house?
By elimination and evidence: meter isolation proves a leak exists, zone pressure testing narrows which line, and staged isolation with camera work closes in on it. The method does the searching so the saw does not have to.
Do you use electronic leak-detection equipment?
Our working method is meter isolation, zone-by-zone pressure testing, and camera inspection, which pins down the overwhelming majority of leaks precisely. For the rare case that calls for specialized electronic pinpointing, we say so plainly and help arrange it rather than opening walls on a guess; honesty about tools is part of honesty about price.
Will you have to tear up my floors or walls to find it?
No. The tools do the searching so the saw does not have to, and demolition is reserved for the repair itself, at the one spot the evidence points to. When a reroute is the smarter path, the floor never opens at all; the failed run stays sealed in the slab and the new line travels overhead.
What are the signs of a slab leak?
A warm spot on the floor, the sound of running water with everything off, a bill that climbed for no reason, moisture at baseboards, or a slab crack that appeared with any of the above. Two or more together make the call worth it today.
What causes pinhole leaks in copper pipes?
Age, water chemistry, and the corrosion that decades of both work into slab-era copper. One pinhole is a warning shot; several within a year or two is the line telling you its era is ending. → /repiping-plumbing-service
