Professional Slab Leak Detection & Repair In Dallas, Fort Worth, & the DFW Metroplex
Slab leaks causing foundation damage, burst pipes, and flooding can’t wait.
Could a Hidden Slab Leak Be Damaging Your Foundation?
Slab leaks develop silently beneath your foundation, causing structural damage and driving up utility bills long before visible signs appear. We handle all common slab leak problems:
- Warm or Damp Floor Spots? Leaking hot water lines beneath your slab warm the concrete and flooring above
- Sound of Running Water? Water sounds beneath your floors when all fixtures are off signal an active slab leak
- Dramatic Water Bill Increases? Slab leaks waste hundreds of gallons daily, causing persistent monthly spikes
- Foundation Cracks or Heaving? Water eroding soil beneath your foundation causes settling and structural damage
- Low Water Pressure? Major slab leaks divert water before it reaches your fixtures, reducing pressure throughout your home
Where Slab Leaks Hide: Detection Methods We Use
Electronic Leak Detection
Sensitive listening devices detect the sound signatures of water escaping pipes beneath your concrete foundation. This non-invasive technology pinpoints leak locations precisely without unnecessary demolition.
Because we know exactly where the leak is before any work begins, we open only what's necessary, protecting your home and keeping repair costs to a minimum.
Pressure Testing
Isolating sections of your under-slab plumbing and monitoring pressure changes identifies exactly which pipe sections are leaking. This targeted approach allows focused repairs rather than wholesale replacement of your plumbing system.
Pressure testing is especially valuable when multiple leaks are suspected, helping us develop a comprehensive repair strategy based on actual system performance data.
Thermal Imaging
Hot water line leaks create warm spots on floors while cold water leaks create cool areas. Infrared cameras identify these temperature patterns that trained technicians recognize as signs of active leaks beneath your foundation.
Thermal imaging is one of the most effective non-invasive tools available for locating slab leaks quickly — reducing diagnostic time and getting repairs underway faster.
Video Camera Inspection
Camera inspection of accessible pipes reveals corrosion, wear, and damage that helps us understand overall pipe condition beneath your foundation. This diagnostic information guides repair strategy and helps identify whether isolated repair or more comprehensive repiping makes better long-term sense.
Understanding the full condition of your under-slab system prevents future surprises and ensures our repair recommendation accounts for the complete picture.
Our Comprehensive Slab Leak Repair Services
Expert Slab Leak Repair Solutions
Not every slab leak requires the same approach. Our licensed plumbers evaluate each situation individually, considering leak location, overall pipe condition, your home’s age and layout, and your budget to deliver lasting results with minimal disruption.
Our repair services include:
- Direct access repair through your foundation for isolated leaks with good overall pipe condition
- Pipe rerouting through walls, attics, or crawlspaces to avoid foundation disruption entirely
- Epoxy pipe lining to seal leaks and prevent future corrosion without excavation
- Partial or complete repiping for homes with multiple leaks or aging systems nearing end of life
- Emergency leak response to stop water flow and minimize foundation damage immediately
Unlike temporary patches, our repairs meet code requirements, include warranties, and are built to protect your foundation for the long term.
Our Leak Repair Process
Every repair starts with precision. We pinpoint exact leak locations before touching anything, so we open only what’s necessary, reducing costs and protecting your home throughout the process.
Our process includes:
- Accurate leak location using advanced detection equipment before any repair begins
- Clear explanation of what caused the leak and which repair option provides the best long-term value
- Quality repairs using materials and techniques matched to your specific pipe type and conditions
- Concrete restoration after direct access repairs, leaving your foundation properly sealed
- Prevention recommendations addressing pipe age, water pressure, and water quality factors
We handle everything from detection through repair so you’re not coordinating multiple contractors to solve one problem.
Signs Your Home May Have a Slab Leak
Because slab leaks sit beneath your foundation, the damage can pile up long before anything looks wrong inside your home. These signs help you catch one before it becomes a major structural repair.
Utility Warning Signs
- Dramatic water bill increases without any usage changes
Water meter still running when all fixtures are off
Low water pressure throughout your home
Persistent monthly bill spikes that continue month after month
Visible Warning Signs
- Warm or damp spots on floors indicating hot water line leaks beneath the slab
- Moisture or mildew smell with no visible water source
- Cracked floor tiles or buckling hardwood from moisture below
- Excessive moisture or standing water near your foundation
Structural Warning Signs
Foundation cracks, settling, or heaving
Unexplained shifts or movement in your home's foundation
Foundation problems combined with any of the above symptoms warrant immediate professional inspection
Soft spots or uneven areas in flooring over the slab

Slab leaks develop when pipes beneath your concrete foundation fail and in the Dallas-Fort Worth area, expansive clay soil makes them more common and more damaging than in most other regions.
Understanding Slab Leaks
Pipe corrosion from aggressive water chemistry and soil conditions
Abrasion and wear from pipes expanding and contracting against surrounding concrete
Poor installation creating stress points at sharp bends or inadequate supports
Ground shifting from foundation settlement or clay soil movement
Excessive water pressure accelerating wear at connection points and pipe bends
Slab Leak Warning Signs
- Sound of running water under floors when all fixtures are off
Warm or damp spots on floors indicating hot water line leaks beneath the slab
Foundation cracks, settling, or heaving
Persistent moisture or mildew smell with no visible water source
Dramatic water bill increases persisting month after month

Understanding Slab Leaks: Why These Problems Develop
Pipe Corrosion
Aggressive water chemistry, soil conditions, and pipe age gradually deteriorate copper pipe walls beneath your slab until leaks develop. Corrosive water or soil works slowly, often over decades, before the damage becomes significant enough to cause an active leak.
Water chemistry in some Dallas-Fort Worth areas is particularly aggressive, shortening the lifespan of under-slab copper pipes faster than in other regions.
Abrasion and Wear
Pipes expand and contract with temperature changes, creating constant friction against the surrounding concrete. Over years, this movement wears through pipe walls at stress points, particularly at bends, joints, and anywhere pipes contact hard surfaces.
Many Dallas-Fort Worth homes have original plumbing installed 40–60 years ago using materials that no longer meet current standards, systems that have reached or exceeded their expected service life.
Ground Shifting and Poor Installation
Foundation settlement, soil movement, and seismic activity stress rigid pipes beneath slabs, causing cracks or connection separations. Poor original installation, including inadequate pipe support, sharp bends, or improper materials, creates additional stress points where failures develop prematurely.
Expansive clay soil throughout Dallas, Fort Worth, and the DFW area shifts with moisture changes, putting more stress on underground pipes than regions with stable soil and making ground movement a leading cause of slab leaks in this area.
Water Pressure and Electrolysis
Excessive water pressure continuously stresses pipes beyond recommended levels, accelerating wear at connection points and pipe bends. High pressure is a particularly common contributing factor in homes that have never had a pressure regulator installed or inspected.
Electrolysis between dissimilar metals in plumbing systems creates galvanic corrosion that accelerates pipe deterioration. Improper connections or grounding issues cause this electrochemical damage, which compounds over time alongside other wear factors.
