In the heart of Texas—spanning from McKinney to Allen, Plano, and beyond—slab leaks are one of the most frustrating plumbing issues homeowners face. These underground leaks are not just annoying; left unchecked, they can lead to expensive repairs, structural damage, and even pose health risks from mold and mildew. At Sewell Plumbing, we understand how stressful these hidden leaks can be, which is why we’re here to help guide you through the causes and detection methods with compassion and care.
Slab leaks are especially relevant in North Texas due to the region’s soil composition, climate, and rapid suburban growth. Whether you’re in Frisco, Celina, or Anna, it’s crucial to understand the warning signs and know when to call in professional support.
Key Takeaway:
Slab leaks are caused by various factors, from shifting soils to corroded pipes, and can be hard to detect without professional help. Timely leak detection services are essential to protect your home and save on costly repairs.
What Causes Slab Leaks in Texas Homes?
Aging Plumbing Systems Beneath Concrete
Older homes in Richardson and Prosper may have galvanized steel or copper pipes that are more susceptible to corrosion over time. These pipes expand and contract due to temperature changes, eventually weakening and causing leaks under the slab. In addition, mineral-rich Texas water accelerates this corrosion process, increasing the risk of failure in your plumbing system.
Homes with outdated systems are also more likely to face issues with their electric water heater or gas water heater, leading to water pressure problems that stress the lines further. If you’re dealing with warm spots on your flooring, it’s time to consider calling a professional for plumbing repair.
Soil Movement and Foundation Shifting
Texas is known for expansive clay soils, particularly in McKinney and Melissa. These soils swell when wet and shrink when dry, putting immense pressure on your home’s foundation. Over time, this movement can lead to cracks in pipes beneath your slab, especially if your home was built without proper soil cushioning techniques.
Foundation shifting also often results in misaligned piping or breakage at pipe joints. This causes water to leak undetected beneath your home—until flooring damage or a spike in your water bill gives it away.
Improper Installation and Construction Flaws
Fast-growing suburbs like Frisco and Plano have seen a boom in new construction, and unfortunately, that sometimes leads to rushed plumbing installations. Poor soldering, bent piping, or lack of protective wrapping around pipes can all contribute to early slab leak failures.
Pipes that rub against concrete or rebar due to improper spacing are vulnerable to abrasion. Over time, this constant friction wears holes in your piping system, leading to a silent but damaging leak beneath your home’s slab foundation.
How Slab Leaks Are Detected
Acoustic Listening Devices and Thermal Imaging
Detecting a slab leak without breaking into the floor used to be a guessing game. Fortunately, our team uses state-of-the-art leak detection tools like electronic listening equipment and infrared thermography to pinpoint leaks with precision.
These non-invasive technologies are especially helpful in modern homes across Allen and Anna, where homeowners seek swift and minimal disruption during plumbing inspections. Using these tools, our plumbing specialists can isolate the problem area and determine the best repair strategy.
Water Pressure and Meter Tests
Unusual fluctuations in water pressure can be a red flag for a hidden leak. Our professionals often conduct pressure tests to measure the rate at which water is escaping from your plumbing lines. A sudden drop points to a breach—often under the slab.
We also perform water meter tests to verify if the system continues to pull water even when fixtures are turned off. If your hot water heater keeps running non-stop, or if you notice constant wet spots, it might indicate a hot water line leak beneath the slab.
Leak Correlation Tools and Video Pipe Inspection
In more complex cases, especially in homes with a history of renovations or additions, we may deploy leak correlation tools that triangulate the exact location of a leak by analyzing sound frequencies. This method is ideal for large properties or commercial plumbing systems in areas like Plano or Richardson.
We also use video pipe inspection to navigate through your plumbing system with high-definition cameras. These help visualize blockages, pipe degradation, and pinpoint slab leak origins—essential for accurate plumbing installation and repair.
Warning Signs You May Have a Slab Leak
Sudden Spike in Your Water Bill
If your water usage hasn’t changed but your bill has, you might have a hidden leak. Homes in Prosper and Celina, where many properties have slab foundations, often experience this issue. It’s crucial to act quickly before the leak undermines your home’s structural integrity.
Warm or Wet Spots on Floors
A hot water line leak will often create warm areas under tile or hardwood floors. Homeowners in Allen and Frisco frequently report such signs, especially near bathrooms and kitchens. This is often an early warning that your water heater replacement or plumbing lines need professional attention.
Mold, Mildew, or Musty Smells Indoors
Excessive moisture from slab leaks can promote the growth of harmful mold under your flooring or walls. If you notice persistent musty smells in your home, particularly in humid areas like Melissa or Anna, don’t ignore it—call a trusted plumber for emergency leak detection.

Answering Common Questions
How do I know if I have a slab leak or just a plumbing issue above ground?
If you’re noticing water damage but no visible source above ground, it’s often a slab leak. Signs like warm floors, unexplained water sounds, or mold under flooring usually point to leaks beneath the concrete.
Can slab leaks cause structural damage?
Yes, if left untreated, slab leaks can erode your foundation, leading to cracks in walls, uneven floors, and even foundation failure over time. Early plumbing repair helps prevent these expensive outcomes.
Is slab leak detection covered by homeowners insurance?
Coverage depends on your policy, but many plans cover the cost of leak detection and some repair work. It’s best to consult your insurer and get professional documentation from a licensed plumber near you.
How Soil Conditions in McKinney Affect Slab Leaks
Expansive clay soil in McKinney causes more foundation movement than other regions. This frequent shifting can lead to cracked water lines under the slab. Homes in this area especially benefit from proactive leak detection and routine plumbing inspections.
The Role of Water Pressure in Pipe Damage
High water pressure, especially in rapidly developing areas like Frisco and Prosper, stresses pipe joints and connections. Over time, this pressure can rupture lines beneath the slab. Installing a water pressure regulator can help preserve your system’s longevity.
