If you notice any of these warning signs in your Katy home, call us immediately at (281) 601-1513.

How much does slab leak repair cost in Katy, TX?

How long does slab leak repair take?

Most slab leak repairs in the Katy area are completed within 1–3 days. Simple pipe re-routing or epoxy lining can often be done in a single day. More extensive repairs involving tunneling under the foundation may take 2–3 days. We work efficiently to restore your water service and minimize disruption to your household.

Does homeowners insurance cover slab leaks?

Many homeowners insurance policies cover the cost of accessing and repairing a slab leak (including breaking and restoring concrete), but coverage varies by policy. The water damage caused by the leak may also be covered. We recommend contacting your insurance provider to review your policy. We can provide detailed documentation to support your claim.

Can a slab leak be repaired without breaking concrete?

Yes — in many cases, slab leaks can be repaired without jackhammering your foundation. Epoxy pipe lining coats the inside of the existing pipe to seal the leak, while pipe re-routing runs a new line through your walls or attic, completely bypassing the damaged section. Our licensed plumbers will assess your situation and recommend the least invasive solution possible.

Our Slab Leak Detection & Repair Services

Not all slab leaks are the same, and not all repairs are created equal. We offer a full range of detection and repair options to address every situation:

Electronic Leak Detection: Our plumbers use electronic amplification equipment to listen for the sound of pressurized water escaping from pipes beneath your slab — pinpointing the leak location without unnecessary digging.
Thermal Imaging: Infrared cameras detect temperature changes in your floor caused by warm water leaking from hot water lines, allowing us to locate the leak non-invasively.
Acoustic Detection: High-frequency acoustic sensors identify the exact leak location by analyzing sound patterns in your pipes — highly accurate even under several inches of concrete.
Epoxy Pipe Lining: For leaks caused by internal pipe corrosion, we can coat the inside of the existing pipe with a structural epoxy liner — sealing the leak without any concrete cutting.
Pipe Re-Routing: We run a new water line through your walls, attic, or crawl space, completely bypassing the damaged section of pipe under the slab. No jackhammering required.
Tunneling & Pipe Replacement: For severe leaks or older galvanized pipes, we tunnel beneath your foundation to access and replace the damaged pipe while protecting the structural integrity of your slab.
Pressure Testing: After every repair, we pressure-test the affected lines to confirm the leak is fully resolved before we leave your property.

Signs You May Have a Slab Leak in Your Katy Home

Slab leaks often go undetected for weeks or months because the damaged pipe is hidden beneath your foundation. Knowing what to look for can save you thousands in structural damage. Watch for these warning signs:

Skyrocketing water bills: A sudden, unexplained increase in your monthly water bill — even though your usage hasn’t changed — is one of the most reliable indicators of a slab leak.
Sound of running water: Hearing water running inside your walls or beneath your floors when every faucet and appliance is turned off points directly to a pressurized leak under the slab.
Warm or wet spots on flooring: Hot water line leaks create warm patches on tile or hardwood floors. Any unexplained dampness or discoloration in your flooring deserves immediate attention.
Cracks in walls or floors: As water erodes the soil beneath your foundation, the slab shifts — causing cracks to appear in your walls, tile, or flooring.
Low water pressure: A significant, sudden drop in water pressure throughout your home can signal a major leak in the supply line running beneath the slab.
Mold or mildew odor: Persistent musty smells — especially near baseboards or flooring — indicate moisture accumulation that could be the result of a slow slab leak.
Foundation damage: Visible buckling, heaving, or sinking of your concrete slab or flooring is a late-stage sign that a slab leak has already caused significant damage.

If you’re experiencing any of these symptoms in your Katy, Cypress, Fulshear, or surrounding area home, call (281) 601-1513 immediately. Early detection dramatically reduces repair costs and prevents structural damage.

What Causes Slab Leaks?

Understanding the root cause of a slab leak helps us recommend the right long-term repair — not just a temporary fix. The most common causes we see in Katy-area homes include:

Corrosion: Older copper pipes corrode over time due to chemical reactions with soil, water chemistry, or stray electrical currents — causing pinhole leaks that grow over time.
Soil Shifting: The expansive clay soils common throughout Houston and Fort Bend County contract and expand with seasonal moisture changes, putting physical stress on buried pipes.
Poor Installation: Pipes installed without proper support or with tight bends can develop leaks at stress points over time, especially under the constant pressure of a home’s water supply.
High Water Pressure: Excessively high water pressure (above 80 PSI) accelerates wear on all plumbing joints and fittings, including those beneath the slab.
Abrasion: Pipes resting directly against concrete or gravel can develop leaks where the pipe surface is worn down by constant friction and vibration.
