Expert Slab Leak Repair in Boerne, TX
A slab leak is not a problem any homeowner in Boerne, TX wants to face, but it's a serious issue that demands immediate attention. Essentially, a slab leak occurs when a water pipe beneath your home's concrete foundation develops a leak. Because the leak is hidden under inches of concrete and soil, it can go undetected for extended periods, slowly causing significant damage to your property before you even realize it's happening.
The warm, humid climate and expansive clay soils common in the Texas Hill Country area, including Boerne, can contribute to foundation shifts. These shifts can put stress on underground plumbing pipes, leading to cracks, breaks, and eventual leaks. Addressing a slab leak quickly and effectively is crucial to prevent escalating costs and extensive damage to your home's structure and value.
Signs You May Have a Slab Leak
Since slab leaks are out of sight, identifying them often relies on recognizing subtle (or not so subtle) indicators within your home or property. Being aware of these signs can help you catch a leak early and mitigate potential harm.
Look out for any of the following:
- Unexplained Increase in Water Bills: This is often one of the first and most telling signs. If your water usage hasn't changed but your monthly bill is unusually high, it could indicate a leak.
- Warm or Cold Spots on Your Floors: If you notice areas on your concrete slab floor that feel noticeably warmer or colder than the surrounding floor, it could mean a hot or cold water line is leaking directly beneath that spot.
- Sound of Running Water: Listen for the persistent sound of running water when all your plumbing fixtures (faucets, toilets, showers) are turned off. This sound might be heard near exterior walls or coming from the floor.
- Wet Spots or Standing Water: Water from a slab leak can seep up through the foundation or travel under the slab and appear as damp spots, puddles, or water accumulation around the exterior of your home's foundation.
- Cracks in Walls or Floors: Constant moisture under the slab can lead to differential settling of the foundation, causing visible cracks to appear in interior walls, ceilings, or the concrete slab floor itself.
- Mold, Mildew, or Musty Odors: Excess moisture trapped beneath flooring or within walls due to a leak creates a perfect breeding ground for mold and mildew. You might notice visual signs of mold or a persistent musty smell.
- Reduced Water Pressure: While not always a direct indicator of a slab leak, a significant drop in water pressure throughout your home could sometimes be related to a leak somewhere in the system, including under the slab.
If you observe one or more of these signs, it's important to contact a professional plumber experienced in Leak Detection + Repair right away.

Causes of Slab Leaks in the Texas Hill Country
Understanding why slab leaks happen can help highlight the importance of professional service and potential preventative measures. Several factors contribute to slab leaks, and some are particularly relevant to the conditions found in Boerne and the surrounding Texas Hill Country:
- Pipe Aging and Corrosion: Over time, pipes can simply wear out. Older homes built with copper pipes are susceptible to corrosion, especially if the soil pH is acidic, leading to pinhole leaks.
- Poor Installation: If pipes were kinked, improperly supported, or had faulty connections during the home's construction, these weak points can fail years later under pressure.
- External Pipe Damage: Shifting soil, root intrusion from trees, or even nearby construction can put external pressure on pipes, causing them to crack or collapse.
- Ground Movement and Foundation Shifting: This is a significant factor in areas with expansive clay soils like ours. Cycles of drought and rain cause the soil to swell and shrink, leading to movement that can stress both the foundation and the pipes embedded within or beneath it.
- High Water Pressure: Excessive water pressure in your home's plumbing system can put undue strain on pipes, increasing the likelihood of leaks, especially in older or weakened sections.
The High Cost of Waiting: Why Timely Repair is Crucial
Ignoring a suspected slab leak is never a good idea. The potential consequences of delaying repair are far more costly and damaging than addressing the problem promptly.
Here’s why waiting can be so expensive:
- Severe Foundation Damage: The most serious consequence. Constant water flow under the slab can erode the supporting soil, leading to uneven settlement, cracking, and potential structural damage to your entire home. This can be incredibly expensive and complex to repair.
- Exponentially Increasing Water Bills: Every day the leak goes unrepaired means gallons of water are wasted, running your water bill higher and higher. This cost accumulates rapidly.
- Mold and Mildew Growth: The persistent dampness creates an ideal environment for mold and mildew to flourish under flooring, behind walls, and in other hidden spaces. Beyond property damage, mold can pose significant health risks.
- Damage to Flooring, Walls, and Belongings: Water seeping up through the slab can ruin flooring (carpet, wood, tile), damage drywall, and even affect furniture and personal items stored near the floor.
- Higher Repair Costs: A small leak addressed quickly is much easier and less expensive to fix than a major leak that has caused extensive damage to the foundation, surrounding soil, and interior structures.
Acting quickly when you suspect a slab leak is the best way to protect your home and your wallet.
Our Advanced, Non-Invasive Slab Leak Detection Process
Finding a hidden leak under a concrete slab requires specialized equipment and expertise. Our approach focuses on accurate, non-invasive detection to pinpoint the leak's location with minimal disruption to your home.
Our skilled technicians use advanced technology, including:
- Acoustic Listening Equipment: Highly sensitive microphones can detect the faint sound of water escaping from a leaking pipe under the slab.
- Thermal Imaging Cameras: These cameras can detect temperature differences on the floor surface caused by hot or cold water leaking below, helping to narrow down the search area.
- Pressure Testing: Isolating sections of your Plumbing Services and applying pressure can help confirm if a leak exists in a specific line.
By combining these techniques, we can precisely locate the source of the leak without resorting to unnecessary, destructive exploration, saving you time, money, and hassle.
Effective Slab Leak Repair Solutions
Once the leak is accurately located, we will recommend the most appropriate repair method based on the leak's location, severity, the type of pipe, and the overall condition of your plumbing system. Common repair options include:
- Spot Repair: If the leak is isolated and easily accessible under the slab, a spot repair involves carefully opening a small section of the concrete directly above the leak to access and repair or replace the damaged pipe section. This is often the least invasive method, but only suitable for specific leak scenarios.
- Pipe Rerouting: In cases where the leak is difficult to access, involves multiple leaks in one area, or the pipe section is in poor condition, it may be more practical and cost-effective to bypass the damaged section entirely. This involves abandoning the leaking underground pipe and installing a new section of pipe through walls or overhead, rerouting the water flow.
- Whole House Repipe: If your home's plumbing system is older, has experienced multiple slab leaks, or shows widespread signs of deterioration, a Whole Home Repiping may be the most durable long-term solution. This involves replacing the entire existing water supply piping system with new, more durable pipes, bypassing all underground lines.

Frequently Asked Questions About Slab Leaks
Here are some common questions homeowners ask about slab leaks:
What causes slab leaks?
Slab leaks can be caused by pipe aging, corrosion, poor installation, external damage, ground movement, foundation shifting, and high water pressure. Local soil conditions in Texas, like expansive clay, significantly contribute to ground movement.
How do you detect them?
We use non-invasive techniques such as acoustic listening, thermal imaging, and pressure testing to accurately pinpoint the leak's location under the concrete slab.
Can they damage my foundation?
Yes, absolutely. This is one of the most severe consequences. Continuous water flow can erode the soil supporting the slab, leading to settling, cracking, and potential structural damage.
What are the signs?
Key signs include high water bills, warm or cold spots on floors, the sound of running water, wet spots, cracks in walls or floors, mold growth, and reduced water pressure.
How are they repaired?
Repair methods depend on the leak but can include spot repair (opening the slab directly above the leak), pipe rerouting (abandoning the old pipe and installing a new one elsewhere), or a Whole Home Repiping (replacing the entire system).
Will my water bill decrease after repair?
Yes, repairing a slab leak eliminates the water waste, which should result in a significant decrease in your water bill, returning it to a normal level based on your actual usage.
How long does detection/repair take?
Detection typically takes a few hours, depending on the complexity. Repair time varies significantly based on the chosen method. A spot repair might take a day, while a reroute or repipe could take longer. We provide an estimated timeline after detection.
Is slab leak repair covered by insurance in Texas?
Homeowners insurance policies vary widely. While the damage caused by a sudden, accidental leak may be covered, the repair of the leaking pipe itself often is not unless it's explicitly included. It is crucial to review your specific policy and contact your insurance provider directly to understand your coverage. We can provide documentation of the leak and necessary repairs for your claim process.
Do you offer emergency service?
Yes, we understand that a slab leak is often an emergency. We offer prompt service to address urgent leak situations.
Can slab leaks affect indoor air quality?
Yes, the moisture from a slab leak can lead to mold and mildew growth, which can release spores into the air and negatively impact indoor air quality, potentially causing health issues for sensitive individuals.
Are older homes more at risk?
Generally, yes. Older plumbing systems are more susceptible to wear, corrosion, and material breakdown, increasing the risk of leaks, including those under the slab. However, issues can occur in newer homes due to installation flaws or external factors.
What should I do if I suspect a slab leak?
Turn off your main water supply if possible to stop the leak temporarily and prevent further damage. Then, contact experienced plumbers specializing in Leak Detection + Repair like us immediately. Avoid attempting to locate or repair the leak yourself, as this can cause more damage.
