Leak Repair San Diego Trusted Local Plumbing Experts
Water leaks in San Diego don’t just waste gallons — they destroy walls, weaken foundations, and send water bills skyrocketing. Whether you’re dealing with a slow drip behind the drywall, a slab leak under your feet, or a corroded pipe that just burst, one thing’s sure: the longer you wait, the worse it gets.
At American Plumbing Co., we specialize in full-service leak detection and leak repair in San Diego, delivering fast, accurate, and long-term solutions. From small fixture leaks to complex underground sewer line failures, we bring over 40 years of local plumbing expertise to every job — with licensed work, real diagnostics, and zero-pressure sales tactics. Our team utilizes non-invasive diagnostics, including thermal imaging, acoustic leak detection, and digital pressure testing, for pinpoint accuracy.
Why San Diego Homes Leak More Than You Think
Most homes in areas such as Clairemont, El Cajon, North Park, and La Mesa were built before modern PEX piping became the standard. These properties often rely on aging copper or galvanized steel lines that corrode over time, especially under San Diego’s mineral-rich water conditions. Pair that with slab-on-grade construction, and you’ve got leaks happening beneath flooring, inside walls, or between joints that haven’t been touched in decades.
That’s why so many of our calls involve pinhole leaks, slab leak detection, and water loss that isn’t visible. These aren’t just nuisances. A slow leak under your slab can lead to thousands in structural damage, warped flooring, mildew behind drywall, foundation moisture problems, and months of rising utility costs before you even realize it.
How We Detect Hidden Leaks
No two leaks show up the same way. Some are obvious — like a dripping faucet or a damp cabinet under the sink. Others are completely hidden until you start seeing signs like musty odors, bubbling paint, or cracks forming in your walls.
Thermal & Acoustic Leak Detection
At American Plumbing Co., we utilize non-invasive leak detection tools, including thermal imaging, acoustic sensors, and digital pressure testing, to locate the source of the leak without tearing open walls or floors. Once we’ve found the issue, we recommend the best solution — whether it’s a direct repair, pipe replacement, or pipe repair service to avoid old or compromised sections.
Slab Leak & Pinhole Leak Repair
We handle:
- Slab leak repair for homes with shifting foundations
- Pinhole leak repair in copper and aging plumbing lines
- Toilet and faucet leak repair to stop slow water loss
- Ceiling and wall leak detection when signs appear, but sources are unclear.
- Irrigation and outdoor leak detection for older yard systems
- Water line reroutes and pipe replacements when repairs aren’t enough.
Signs You Might Have a Leak Even if You Don't See Water
You don’t need visible flooding to be in trouble. The most damaging leaks are usually the ones you can’t see. If you’ve ever asked, “Why is my water bill so high?” or “How do I find a hidden leak in my home?” here’s what we tell San Diego homeowners every day:
Listen for water running when no fixtures are in use. Watch for discolored paint, soft spots on the floor, or a sudden increase in your utility bill without corresponding increased usage. Hot areas on the tile may signal a hot water slab leak, and a persistent musty smell could mean that the water has been trapped behind the wall. These are the first signs we hear about in neighborhoods across Chula Vista, Serra Mesa, and University Heights, and they almost always lead us to a deeper problem that needs fast attention. Many homeowners also notice alerts from smart water meters when water is running while no taps are on.
What Happens When You Call Us
We don’t walk in swinging a sledgehammer. Our job is to solve the problem, not create a bigger one.
When you call us, we start with fundamental questions about your home, your plumbing system, and the symptoms you’re seeing. Then, we send a licensed, uniformed plumber, not a commission-driven tech, who arrives equipped to perform non-invasive leak detection and precise diagnostics on-site.
If we identify the issue, you’ll receive a clear explanation, flat-rate pricing, and repair options tailored to your home’s specific needs — not a one-size-fits-all package. We offer same-day repairs when possible and clean up after ourselves as professionals should.
Whether the leak requires a single pipe repair or a more extensive water line reroute, our approach is based on transparency, speed, and long-term results — not guesswork.
