Slab Leak Detection in Keller, TX

Serving Keller Since 1991: Free Estimates, 24/7 Emergency Response

A slab leak is a water line failure beneath your home’s concrete foundation. Out of sight, it quietly causes water damage, mold growth, and foundation movement long before it becomes obvious. When you suspect something is wrong, you need someone who picks up the phone and can tell you exactly what’s happening beneath your floor. ABC Plumbing has been serving Keller and the greater Fort Worth area since 1991, and that’s what we do.

Every detection visit starts with a free onsite estimate. Repairs are backed by a 90-day parts and labor warranty. And if you’re calling at 2 a.m. because your water bill just tripled, someone can answer.

Call ABC Plumbing now at (817) 854-4007 for slab leak detection in Keller. We’re available 24/7, including nights, weekends, and holidays.

Why Keller Homes Are Especially Vulnerable

Tarrant County sits on Blackland Prairie clay, documented by the USDA Natural Resources Conservation Service as having high to very high shrink-swell potential. The soil beneath your foundation expands when wet and contracts sharply when dry, cycling with every rain and drought. Every cycle bends the copper pipes embedded below your slab at every joint, elbow, and direction change.

Homes built before 1995 are particularly at risk. Original copper supply lines weren’t designed to flex with ongoing foundation movement, and decades of Tarrant County’s hard water accelerate interior corrosion on top of that mechanical stress. If your Keller home is more than 30 years old and hasn’t had its supply lines evaluated, the soil has been working on those pipes for a long time.

Signs You May Have a Slab Leak

These symptoms don’t always appear together, but any one of them is worth a call:

• Unexplained water bill increase with no change in household use or irrigation
• Sound of running water when every faucet, toilet, and appliance is confirmed off
• Warm or damp spots on the floor, especially on tile or hardwood, pointing to a hot water line failure below
• New drywall cracks, sticking doors, or gaps around window frames caused by uneven slab movement from saturated soil
• Mold or mildew odor rising through flooring seams or from baseboards on the first floor without a visible source
• Low water pressure across multiple fixtures alongside a rising bill

How We Locate Slab Leaks Without Tearing Up Your Floor

We use non-invasive detection methods to find the leak precisely before anything is opened. Three tools work together to identify the source before any floor or concrete is disturbed.

Pressure Isolation Testing
Pressure isolation testing separates the hot and cold supply lines independently to confirm which side is losing pressure and how significant the loss is. This establishes scope before detection equipment is deployed.

Acoustic Leak Detection
Acoustic leak detection amplifies the sound of pressurized water escaping beneath the slab, letting us localize the leak point without penetrating your floor or concrete.

Thermal Imaging
For hot water line failures, thermal imaging reads the heat signature on the floor surface above the leak, giving us a second data point that narrows the location further. We know where we’re going before we cut anything.

Texas state law requires licensed, insured plumbing contractors for both slab leak detection and repair. Every technician we send is fully licensed and insured.
