Sewer Leak Detection in Keller | Keller Leak Detection Pros

Sewer Leaks Hide Underground — Until They Don't

A leaking sewer line can undermine your foundation, soak your yard with wastewater and fill your home with sewer gas long before a drain ever backs up. Sewer leak detection in Keller finds breaks, bellies and root intrusion early — with camera inspection, not guesswork or a backhoe.

Keller's older neighborhoods include homes with aging cast iron and clay sewer lines, and even newer PVC lines suffer when clay soil shifts and joints separate.

Signs of a Sewer Line Leak

Sewer or rotten-egg odors indoors or in the yard
Slow drains throughout the house, not just one fixture
Gurgling toilets or drains when other fixtures run
Soggy, extra-green patches of lawn over the sewer line path
Foundation cracks or settling near the line's route
Frequent backups that keep returning after clearing
Mold or moisture along the lowest walls of the home

Camera Inspection and Isolation Testing

Our sewer leak detection starts with a video camera inspection: a waterproof camera travels the line from an access point, showing breaks, root masses, bellies that hold water, and separated joints on screen — with the exact distance marked, so any repair digs in one precise spot.

Where the question is whether the sewer system itself is leaking under the slab, hydrostatic and isolation testing checks each section of the system separately. That tells us not just that the sewer leaks, but which segment — under the slab, in the yard, or at the city connection — so the repair plan targets the right section only.

Why Sewer Lines Fail in Keller

The same expansive clay that stresses water lines moves sewer pipes too — a joint that was tight at installation can gap after years of soil cycles. Cast iron lines corrode from the inside out over decades, tree roots enter through any opening and grow into blockages, and heavy rain can expose bellies and breaks as the ground saturates. A camera inspection shows the line's true condition, whatever its age.

Reading Your Camera Inspection: Five Things We Look For

When we run a camera through your sewer line, you'll watch the same screen we do. Here's the plain-language version of what the footage tells us:

Belly — a sagging section where the pipe dips and holds water permanently. Bellies collect solids, cause recurring slow drains, and usually trace back to soil that shifted or washed out beneath the pipe.
Offset joint — two pipe sections that no longer line up, so an edge sticks into the flow. Offsets catch debris and are where leaks begin at the seam.
Root intrusion — fine root hairs or full root masses growing in through a joint or crack. On camera it looks like a plant growing inside your pipe, because it is one.
Channeling and scale — in old cast iron, corrosion eats a channel along the pipe's bottom until the wall is paper-thin. Heavy orange scale on the screen means the line is living on borrowed time.
Cracks and breaks — clean fractures from ground movement or a crushed section under a driveway. These are the segments actively leaking sewage into the soil — often the same spots softening the ground under a slab.

Every finding gets a distance measurement from the access point, so if a repair is needed, the digging happens in exactly one place. You keep the findings summary either way — it's your line, and the footage is your information.

Frequently Asked Questions

How does a sewer camera inspection work?

A flexible cable with a waterproof camera and light is fed through a cleanout or access point. We watch the line's interior live, record problem areas and measure their exact distance from the access point, so repairs are located precisely.

Can you tell if the leak is under my slab or in the yard?

Yes. Isolation testing checks the under-slab system and yard line separately, and the camera inspection visually confirms where the damage is. Knowing the segment determines the repair approach and cost — which is why detection comes first.

What are tree roots doing in my sewer line?

Roots seek the water and nutrients inside sewer lines and enter through tiny joint gaps or cracks. Once inside, they grow into masses that trap debris and widen the opening. The camera shows exactly where roots have entered and how much of the line they affect.

Is a sewer leak a health concern?

It can be. Escaping wastewater saturates soil around and under the home, and sewer gas entering the house is unpleasant and unhealthy. A leaking line also erodes soil beneath slabs and driveways. It is worth diagnosing promptly.
