Water Leak Repair in Castroville & San Antonio, TX

Advanced Leak Detection

We specialize in precise leak detection services to protect your home and water supply. Whether it’s a leak in a wall, ceiling, foundation, or under your slab, we use specialized tools and methods to locate the issue quickly and safely.

• Hydrostatic Testing – We fill your water lines with dyed liquid and pressurize the system to find pressure loss that reveals leak locations. This method is effective for detecting even subtle shifts in pressure.
• Pinpoint & Isolation Testing – By isolating specific sections of your plumbing, we can test each individually to pinpoint the exact leak site without tearing into walls or floors.
• Electronic Leak Detection – When visual inspections aren’t enough, we use electronic sensors to detect sound frequency changes caused by water leaks behind walls, beneath concrete, or underground.

We also inspect for gas line leaks and test for pressure loss to ensure the entire plumbing system is safe and up to code.

Slab Leaks & Underground Issues

Slab leaks are among the most destructive types of water leaks in South Texas. These develop in water lines under your home’s foundation and can lead to:

• Foundation cracks
• Mold growth
• Flooding and yard damage
• Increased utility bills

These leaks are common in older homes in Castroville, especially where ground shifting or pipe corrosion occurs. Left unchecked, slab leaks can undermine your home’s foundation. That’s why our team responds quickly with trenchless repair services or pipe replacement if needed, restoring the integrity of your property.

Comprehensive Repair Services

Once a water leak is located, our Castroville plumbing experts provide targeted repair services that restore your system without unnecessary disruption. In many cases, we can complete a permanent repair on the spot—no need for a temporary fix that won’t last. We prioritize:

• Minimally invasive access
• Long-lasting solutions
• Transparent estimates before any work begins

We always attempt to repair the existing water pipe first. But when damage is too extensive—due to rust, root intrusion, or poor previous repairs—we may recommend a full replacement to ensure your water supply and pressure remain stable long term.
