Why Northern California Homes Leak More Than You'd Think
I'll be straight with you — Northern California is not an easy environment for plumbing. Older homes across the valley were built on slab foundations, which means water lines run directly beneath your concrete floor. When those lines fail, the leak is completely invisible until it's not.
A lot of our work in Chico, Redding, and Yuba City involves homes built in the 1950s through 1970s — houses with original cast iron supply lines and copper that's been fighting high-mineral water its entire life. That mineralized water corrodes copper from the inside out, faster than most homeowners realize. (We once found a pipe that looked perfectly fine from the outside and had a pinhole you could barely see with the naked eye — it had been running water under a slab for months.)
Add in aging galvanized steel, hard water scale, and the temperature swings we get from valley summers to foothill winters, and you have a recipe for hidden leaks that can cost thousands in water bills and structural damage before they announce themselves. Earl's Plumbing has been pulling these problems out of Northern California homes since 1998 — we know what to look for, and we know how to fix it right the first time. If your home needs a full house repipe, we handle that too.
Our Leak Detection & Repair Services
From a suspicious water bill to an active emergency — here's how Earl's Plumbing covers the full spectrum of leak problems.
Slab Leak Detection
Electronic acoustic listening equipment lets us locate breaks in water or drain lines beneath your concrete slab — without tearing up your floor to find them. We pinpoint first, then repair.
Hidden Pipe Leak Detection
Leaks inside walls, ceilings, or underground don't announce themselves. We use pressure testing and listening tools to find them before the damage gets worse. Pair with our video inspection service for complete diagnosis.
Water Line Leak Repair
Whether it's a pinhole in your copper supply line or a cracked galvanized fitting, our technicians make durable repairs that restore your water pressure and stop the waste. All work is backed by a 1-year warranty.
Gas Leak Detection
A gas leak is a life-safety issue — not a wait-and-see situation. If you smell gas or suspect a leak in your gas lines, call Earl's immediately. Our technicians are trained and equipped to locate and repair gas leaks safely. See also our underground line location service.
Sewer Line Leak Inspection
Sewer line leaks can cause foundation damage, sinkholes, and serious sanitation issues. We inspect sewer lines for leaks, offset joints, and root intrusion using camera technology. Check out our full drain and sewer cleaning services too.

An active burst pipe or slab leak can flood a home in hours. When you're dealing with an emergency, call the nearest Earl's office directly — Chico (530) 343-0330, Redding (530) 244-3275, Yuba City (530) 674-0330. We respond fast.
Signs You May Have a Hidden Water Leak
These six symptoms are the most common early warnings that something is leaking inside your walls, under your slab, or in your yard — often long before visible water damage appears.
Unexplained spike in your water bill
Sound of running water with nothing on
Wet spots, staining, or soft drywall with no visible source
Low water pressure throughout the house
Warm or damp spots on floors — a classic slab leak sign
Musty smell or mold appearing without an obvious cause
Notice any of these? Don't wait for it to get worse. Schedule an inspection or call your nearest Earl's office — no service call fee, ever.
"Working with Earl's on a leak in our home's crawl space was one of the BEST service experiences we've ever had! Everyone was so professional, from the person we initially called… to our technician himself, Travis. Travis was on time, friendly, professional and eager to get the job done. He gave us a quick no-obligation estimate and we went for the repair. He got it done quickly and completely! He identified the exact issue and fixed it so fast."
