Episode 03: Slab Leaks
What Is a Slab Leak—and How Do You Know If You Have One?
If you’ve noticed mysterious water bills, warm spots on the floor, or the sound of running water when everything is off, you might have a slab leak. These hidden plumbing leaks happen under the concrete foundation of your home—and they can cause serious damage if left untreated.
At North County Plumbing, we help homeowners across Templeton, Atascadero, Paso Robles, and surrounding areas detect and repair slab leaks quickly and effectively. Here’s what you need to know.
⸻
What Causes a Slab Leak?
Your home’s water lines often run beneath the concrete slab foundation. Over time, several factors can cause those pipes to leak:
• Aging or corroded copper or galvanized pipes
• Earth movement or settling foundations
• Abrasion from pipes rubbing against concrete
• High water pressure or poor installation
Slab leaks are more common in older homes, especially those built before the 1980s, which are common in North County communities.

Signs You Might Have a Slab Leak
Because slab leaks are hidden under the concrete, they’re not always easy to spot. Watch for these red flags:
• Unexplained spikes in your water bill
• Warm or damp spots on flooring
• Cracks in walls or foundation
• The sound of running water when no fixtures are in use
• Moldy or musty odors near baseboards or carpets
• Low water pressure throughout the house
If you’re seeing any of these symptoms, don’t wait—slab leaks can lead to structural damage, mold growth, and skyrocketing water costs.

How We Detect Slab Leaks
At North County Plumbing, we use advanced, non-invasive technology to locate slab leaks without tearing up your floors. Our leak detection process includes:
• Acoustic listening equipment to detect pressurized leaks
• Pressure testing of lines to confirm presence of leaks
• Thermal imaging for warm water line detection
• Moisture readings to track water migration beneath flooring
Once we locate the problem, we’ll present your repair options clearly—no upselling, just honest solutions.

Slab Leak Repair Options
Depending on the location and severity of the leak, we may recommend:
• Direct access repair – Open the slab and repair the damaged pipe
• Repiping – Reroute plumbing lines above the slab to prevent future leaks
• Epoxy lining – Seal small leaks from inside the pipe (in some cases)
We’ll help you choose the best approach for your home, your budget, and your timeline.
