What Is a Slab Leak and Why Does It Matter
Slab leaks occur when water lines beneath your concrete foundation break or crack. These underground leaks can happen due to pipe corrosion, shifting soil, poor installation, or age-related wear and tear. Since they’re hidden, slab leaks often go unnoticed until visible symptoms appear, such as damp flooring or a sudden drop in water pressure.

The danger lies in how quickly the damage can escalate. Even a small, slow leak can compromise your foundation and cause structural issues, mildew, or mold growth. In some cases, slab leaks may also impact your home’s resale value or result in insurance complications if not addressed early. That’s why homeowners in Noblesville, IN, count on Thornton Plumbing for prompt and professional service to detect and repair slab leaks with minimal disruption.
Signs You May Have a Slab Leak
Knowing the early warning signs of a slab leak can save you thousands in repairs. Because slab leaks occur below your home, they’re not always obvious at first. However, there are some red flags to watch out for that may indicate a leak is present under the foundation.
- Unusually high water bills without a clear explanation
- Damp, warm, or wet spots on the floor, especially near bathrooms or kitchens
- Low water pressure throughout the home
- The sound of running water when no taps are open
- Cracks in your walls or flooring, which may signal shifting caused by water damage
- Mold or mildew smells, particularly in lower levels or basements
If you notice any of these signs, don’t delay. Call Thornton Plumbing right away for a professional inspection. Our expert plumbers use non-invasive leak detection methods to locate the problem and provide straightforward, affordable solutions.
How We Detect Slab Leaks
At Thornton Plumbing, we take slab leak detection seriously. Our team uses advanced diagnostic equipment like electronic leak locators, thermal imaging cameras, and pressure testing to precisely identify the location of leaks without tearing up your floors. This allows us to pinpoint the problem with minimal disturbance to your home.
Our process begins with a thorough inspection of your plumbing system. We check for pressure loss, analyze water usage patterns, and perform acoustic testing to find leaks under the slab. Our trained technicians can differentiate between minor moisture issues and significant leaks that require immediate action. We communicate our findings clearly and walk you through all repair options, so you’re never left in the dark about what’s next.
Slab Leak Repair Options
Once a slab leak is located, we’ll help you choose the best repair method based on the severity and location of the issue. At Thornton Plumbing, we offer several effective slab leak repair options:
- Pipe rerouting: We bypass the damaged section by installing a new water line through your walls or ceilings. This is ideal when leaks occur in hard-to-reach or high-risk areas.
- Direct access repair: If the leak is easily accessible, we may remove a small portion of the slab to fix the broken pipe directly.
- Epoxy pipe coating: For small leaks or corrosion, we can apply an epoxy lining inside your pipes to seal the damage without excavation.
- Trenchless repiping (if applicable): In certain cases, we may recommend trenchless technology to repair or replace lines under the slab without major digging.
Our plumbers always aim for the least invasive option while ensuring a long-term fix. You can count on honest recommendations and quality workmanship from start to finish.
