Slab Leak Repair Services in Cibolo, TX
A slab leak is a plumbing issue that occurs beneath the concrete foundation of a home or building. Because the leak is hidden from view, it can go undetected for a long time, causing significant damage before the problem becomes obvious. For homeowners in Cibolo, TX, understanding the signs of a potential slab leak and knowing when to seek professional help is crucial for protecting their property. These leaks can erode the soil supporting the foundation, lead to structural instability, and foster the growth of mold and mildew, creating a hazardous environment.
Prompt detection and repair are essential to mitigate damage and avoid costly repairs down the line. Addressing a slab leak requires specialized knowledge, equipment, and techniques to accurately locate the source of the leak and implement the most effective repair strategy without causing unnecessary disruption.
Identifying the Signs of a Slab Leak
Recognizing the early indicators of a slab leak is vital for timely intervention. While some signs may seem minor initially, they often point to a hidden problem beneath your foundation. Keep an eye out for any of the following:
- Unexplained Increase in Water Bill: A sudden and significant spike in your water bill that isn't due to increased usage is one of the most common indicators of a leak, including one under the slab. Even small leaks can waste large amounts of water over time.
- Warm Spots on Floors: If you notice specific areas of your floor feeling unusually warm, it could indicate a hot water line leak under the slab. The hot water heats the concrete above it.
- Sounds of Running Water: Hearing the distinct sound of running or dripping water when no faucets, toilets, or appliances are in use can be a sign of a continuous leak somewhere in your plumbing system, potentially beneath the foundation.
- Cracks in the Foundation or Walls: Persistent moisture under the slab can cause the soil to expand and contract, leading to stress on the foundation. This stress can manifest as cracks in the concrete slab itself or in the interior walls of your home.
- Wet Spots or Mildew Growth: Visible wet spots on carpets or flooring, especially along walls, without an obvious source like a spill, can indicate water seeping up from beneath the slab. The constant moisture can also lead to mold or mildew growth and associated musty odors.
- Reduced Water Pressure: A significant leak under the slab can divert water away from your fixtures, resulting in a noticeable drop in water pressure throughout your home.
If you observe one or more of these signs, it's recommended to investigate further or contact Roadrunner Plumbing & Air to handle potential slab leaks.

Common Causes of Slab Leaks in Texas Homes
Slab leaks can occur for various reasons, sometimes due to factors common in areas like Texas with expansive soils. Understanding the causes can help in preventing future issues. Some common culprits include:
- Soil Shifts and Settlement: The soil beneath your foundation can shift over time due to changes in moisture content, such as heavy rains or prolonged dry periods. This movement can put stress on the pipes embedded in or under the slab, leading to cracks or breaks.
- Pipe Corrosion: Many older homes have copper pipes that can corrode over time, especially if the water chemistry is aggressive or if the pipes react with materials in the surrounding soil or concrete. This corrosion weakens the pipes, making them susceptible to leaks.
- High Water Pressure: Excessively high water pressure within your plumbing system puts constant strain on pipes and joints. Over time, this can lead to failure, particularly in older or weaker sections of pipe under the slab.
- Poor Installation: Errors during the initial plumbing installation or during the pouring of the concrete slab can create weak points or damage pipes, leading to premature leaks. This can include pipes being bent incorrectly, resting on sharp objects, or inadequate protective sleeves.
Given the potential causes, the plumbing system under your slab is vulnerable to issues that are not easily addressed without specialized knowledge.
The Importance of Professional Slab Leak Detection
Locating the precise source of a slab leak is challenging because the pipes are hidden beneath concrete. DIY attempts to find the leak often involve guesswork and potentially unnecessary damage to your property. Professional Leak Detection + Repair services utilize advanced technology to pinpoint the leak location with accuracy and minimal intrusion.
Trained technicians employ various tools and techniques, including:
- Acoustic Listening Equipment: Sensitive microphones can detect the subtle sounds of water escaping from a pipe under pressure, even through concrete and soil.
- Thermal Imaging Cameras: These cameras can identify temperature differences on the floor surface, helping to locate hot water leaks under the slab by showing warmer areas.
- Pressure Testing: Isolating sections of the plumbing system and testing them under pressure can help confirm the presence of a leak and narrow down the affected area.
- Sewer Camera Inspection: While primarily used for sewer lines, cameras can sometimes be used to inspect certain types of pipes accessible from drain openings, potentially identifying issues close to the slab.
Accurate detection prevents unnecessary damage from exploratory digging and ensures that the repair is targeted precisely where needed.
Slab Leak Repair Methods
Once a slab leak has been accurately located, the repair method depends on several factors, including the type of pipe material, the location of the leak, the severity of the damage, and the overall condition of the plumbing system. Common repair approaches include:
- Direct Access Repair: This method involves carefully breaking through the concrete slab directly above the leak location to access and repair or replace the damaged section of pipe. This is often the most straightforward method for isolated leaks, but it does require repairing the slab afterward.
- Pipe Rerouting (Re-piping): In cases where there are multiple leaks, the pipes are extensively corroded, or accessing the leak directly is impractical or highly disruptive, the damaged section of pipe can be abandoned, and a new pipe can be run through walls or the ceiling to bypass the area under the slab. This is essentially a partial Whole Home Repiping focused on the affected line. This method avoids breaking the slab but involves minor work within the home's structure.
- Trenchless Pipe Repair: While more commonly associated with main sewer lines, some trenchless methods like pipe lining or pipe bursting might be applicable in specific situations for certain types of pipes accessible from either end. However, for standard under-slab supply lines, direct access or rerouting are generally more common repair solutions.
A plumbing professional specializing in slab leaks can assess your specific situation and recommend the most appropriate and cost-effective repair method.

- Foundation Damage: The continuous presence of water can erode the soil supporting the foundation, leading to differential settlement, cracking, and potential structural damage to the home.
- Mold and Mildew Growth: Constant moisture provides an ideal environment for mold and mildew to flourish under floors, in walls, and within the structure, potentially causing health problems and requiring expensive remediation.
- Structural Issues: In severe cases, prolonged water exposure can compromise the structural integrity of the building, affecting load-bearing walls and floors.
- Increased Water Bills: The leak will continue to waste water, leading to persistently high utility bills until it is fixed.
- Damage to Flooring and Property: Water seeping up through the slab can ruin carpets, hardwood floors, and other flooring materials, as well as damage furniture and belongings.
