Signs You May Have a Slab Leak
Slab leaks don’t always show themselves right away, but there are usually clues if you know what to look for. Catching these signs early can help you avoid more extensive damage to your home’s foundation and flooring.
Watch for these warning signs:
- Unexplained increase in your water bill
- Warm spots on your flooring
- Sound of running water when everything is off
- Low water pressure throughout the home
- Damp carpet or flooring with no clear cause
- Cracks in walls or flooring
- Mold or mildew smell without a visible source
If you’re noticing any combination of these signs, it’s worth calling a plumber promptly. Slab leaks tend to get worse the longer they go unaddressed, and the resulting water damage can become far more expensive than the plumbing repair itself.
How We Detect Slab Leaks
Finding a leak beneath a concrete slab requires more than guesswork, and it’s not something that should involve tearing up your entire floor to search for the source. At Harry Hayes Plumbing, our slab leak detection process in Jacksonville, FL, relies on specialized equipment designed to locate leaks accurately without unnecessary damage to your home.
We use acoustic listening devices that can pick up the sound of water escaping from a pressurized line, even through concrete. In many cases, we also use thermal imaging to identify temperature variations in the flooring that indicate where water is escaping and pooling beneath the surface. When additional confirmation is needed, we may use pressure testing to isolate which line is affected.
This combination of tools allows us to pinpoint the leak’s location with a high degree of accuracy before any work begins. That precision matters because it means we open up only the area that actually needs attention, rather than guessing and creating more disruption than necessary.
Slab Leak Repairs
Once we’ve confirmed the location of a slab leak, we walk you through your options for slab leak repair in Jacksonville, FL, clearly and honestly. Depending on the specifics of your situation, there are a few different approaches that may make sense.
Direct access repair involves opening a small section of the slab right above the leak to reach and fix the damaged pipe. This approach works well when the leak is isolated to a single, accessible location. Pipe rerouting is another option, where we run a new line above the slab or through walls instead of repairing the original line beneath the foundation. This method avoids cutting into the concrete altogether and can be a good fit depending on your home’s layout.
For homes with aging or failing pipe materials throughout the slab, a broader repiping approach may be the more cost-effective long-term solution rather than repairing leaks one at a time as they occur. We’ll give you a straightforward recommendation based on what we find, along with the pros and cons of each option, so you can make the decision that’s right for your home and your budget.

Frequently Asked Questions
How do I know if I have a slab leak versus another type of plumbing issue?
Slab leaks often come with specific signs like warm spots on your floor, the sound of running water when nothing is in use, or unexplained spikes in your water bill. If you’re seeing these signs along with low water pressure or damp flooring, a slab leak is a likely culprit, and professional detection can confirm it.
Is slab leak detection invasive?
No. We use acoustic equipment and thermal imaging to locate the leak without needing to break into your flooring first. This lets us confirm the location before any repair work begins, which keeps the process as non-invasive as possible.
How much damage can a slab leak cause if left untreated?
Left unaddressed, a slab leak can lead to foundation damage, mold growth, warped flooring, and even structural issues over time. The water bill also keeps climbing the longer the leak goes unresolved.
Will my homeowner's insurance cover slab leak repair?
It depends on your specific policy. Many policies cover the cost of accessing and repairing the leak but may not cover the underlying cause or the water damage itself. We recommend checking with your insurance provider, and we’re happy to provide documentation from our detection and repair process.
How long does slab leak repair take?
Most direct access repairs can be completed within a day. Pipe rerouting or more extensive repiping work may take longer, depending on the scope of the project. We’ll give you a clear timeline once we’ve confirmed the best repair approach for your home.
