Under-Slab Plumbing Services for Henderson Homes

Everything we do happens below the floor you walk on. Whether it is a hot water line leaking into the slab, a cast iron sewer that has cracked, or a remodel that needs a toilet moved across the room, the goal is the same: find the problem precisely, reach it with as little disruption as possible, and leave the home in better shape than we found it. Most of our work is done by tunneling from outside the foundation, but we also explain when a reroute, lining or a small floor opening is the smarter call. Start with the service that fits your situation below, or reach out if you are not sure which one applies to your home.

Choose the service that matches the problem

Slab Leak Repair

A hidden water line leak under the floor gets pinpointed first, then fixed through a short tunnel or a clean reroute, whichever suits the pipe.

Sewer Line Tunneling

When the main building drain cracks or sags beneath the house, we replace it from below through a tunnel and leave every finished room untouched.

Drain Line Replacement

One shower, tub or kitchen drain giving trouble? We replace just that branch under the concrete, whether cracked cast iron, aged ABS or a sag.

Remodel Plumbing Relocation

New island, moved toilet or curbless shower? We reroute drains beneath the concrete with correct slope so the new floor plan works from day one.

Camera Inspection and Leak Detection

Video, listening gear, thermal imaging and pressure tests show what is actually failing below your floor, and where, before anyone breaks ground.

Water Line Leaks and Leak Location

Repairing leaks in water lines below the slab

Pressurized water lines under the slab can develop pinhole leaks, especially older copper in established parts of Henderson. Our water line slab leak service covers locating the leak, tunneling to it for a spot repair, or rerouting the line through walls or the attic when the old pipe is no longer worth saving. We walk you through both options and the reasoning behind our recommendation, so the decision stays yours and is based on evidence you can see.

Finding the problem before anything is opened

Most under-slab mistakes come from guessing. Our sewer camera and electronic leak location work uses pressure testing, acoustic listening, thermal imaging and video inspection to narrow down what is failing and where. Sometimes that visit is all you need: the result may show a simple fix above the slab, or confirm that the line is healthy and the problem is somewhere else entirely.

Sewer and Drain Lines Under the Slab

Replacing the main building drain by tunnel

The main drain that carries everything out of the house often runs the full length of the slab. When it cracks, separates or sags, opening the floor can mean tearing through several rooms. Our main sewer tunneling service replaces that line from below, with the tunnel backfilled and compacted when the work is done, and your finished floors left alone.

Fixing individual drain branches

Not every drain problem involves the main line. A single branch from a shower, tub or kitchen can belly, crack or corrode while the rest of the system is fine. Our under-slab drain branch replacement targets just the failed run, whether it is older cast iron, aging ABS or a section that has settled out of grade. Fixing only what is broken keeps the job smaller and more predictable for you, and it leaves healthy pipe alone where it belongs.

Remodels and Choosing the Right Approach

Moving plumbing for a new layout

Kitchen islands, curbless showers and relocated toilets all need drains in new places under the slab. Our plumbing relocation for kitchen and bath remodels plans the new drain routes with proper slope, coordinates with your general contractor or designer, and gets the rough plumbing ready for inspection. In many remodels the floor is coming up anyway, so we will tell you when trenching from inside makes more sense than a tunnel.

How we recommend one method over another

We weigh the location of the problem, the condition of the rest of the pipe, what sits on the floor above it, yard access, and any HOA limits on exterior work. Then we lay out the options side by side, including the ones we do not perform. Our goal is the repair that fits your house, not the one that keeps a crew busiest. If you want a second look at a recommendation you already have, that is a perfectly good reason to reach out to us.
