Plumber repairing pipe as part of a larger sewer line replacement project

Sewer Line Replacement

Not every sewer problem needs replacing — but when repair stops making sense, we camera the line first, walk you through the yard, through-floor and tunnelled options honestly, and handle the permit and inspection so the job is done right.

Repair and replacement solve different problems, and the camera inspection is what tells us which one your line actually needs. A single break or an isolated root intrusion is usually a repair. Replacement becomes the right call when the same section keeps collapsing after repeated repairs, when root damage runs extensively along the pipe rather than at one point, when older clay or cast iron has developed a long offset or bellied stretch that repeated cabling can't fix, or when a pre-sale inspection has flagged the line as a disclosure item a buyer's lender won't ignore. We show you the footage and explain why repair either will or won't hold before recommending replacement.

How a line gets replaced depends on where it runs. An exterior or yard run is the most straightforward and the least disruptive to the house. A line under the slab is replaced either through the floor — opening the slab from inside — or by tunnelling underneath it from outside, which leaves your floors intact but costs more. On a house with original cast iron throughout, replacing the whole system at once is usually better value than paying three times for three separate sections. We camera and locate the line first so the recommendation is based on what is actually down there, and we tell you plainly which method your line calls for rather than defaulting to whichever is easier for us.

Texas municipalities require a permit for sewer line replacement, and most require a city inspection before the trench or access pits are closed up. We pull the permit and schedule the inspection as part of the job — it's built into how we sequence the work, not an extra step you have to chase down yourself. Because this is one of the larger jobs a home will ever need, payment options are available — ask when we quote yours.

Upfront pricing — three ways to get one

Flat-rate, approved by you before any work starts. You pay for the work, not for a truck in your driveway. What you pay to find out depends on what you already know.

Know what needs replacing?

Photo or phone quote

Water heater, toilet, faucet, disposal, a repipe — anything where you already know what needs replacing. Send a photo and we price it without sending a truck. Costs you nothing, obligates you to nothing.

Don't know what's wrong?
$150

Service visit

A licensed plumber diagnoses it on site. Covers the visit and the first 30 minutes of work — and it applies to the repair if you go ahead with one. It is also our minimum charge, so a small fix is often this and nothing more.

Need a specific test?
From $189

A named diagnostic

Pressure and PRV test, hydrostatic test, sewer scope, camera inspection, slab leak investigation. Each one is a fixed price with a written result you keep — real work with a real deliverable, not a sales call.

Evenings, weekends and holidays add a $149 after-hours fee, which members don't pay. The flat rate for the work itself never changes, and you approve every number before we start.

Frequently Asked Questions

How much does sewer line replacement cost in Dallas?
The number follows the method and the scope: an exterior yard run starts at $4,495, through the floor at $5,495, and tunnelled under the slab at $8,995, each with a per-foot rate beyond the base length; a whole-house cast iron replacement is $18,500. What moves it is the length and depth of the line, how much has to be opened up, the pipe material and diameter, and whether the permit and city inspection add scheduling steps. Every flat rate includes the camera-verified diagnosis, the permit pulled on your behalf, all materials and labor as quoted, passing the required city inspection, site restoration, and a 1-year workmanship warranty. Replacing a fixture? Send a photo and we'll quote it free. If the problem needs diagnosing, the $150 service visit covers that and the first 30 minutes — and it applies to the repair. You approve the flat rate before any work starts.
How do I know if I need repair or full replacement?
We start every sewer call with a camera inspection, because guessing costs more than looking. Recurring collapse in the same spot, extensive root damage along the pipe rather than one location, a long offset or bellied section in old clay or cast iron, or a disclosure issue flagged before a home sale all point toward replacement. An isolated break or a single intrusion point is usually still a repair. You'll see the footage and hear the reasoning either way.
Is it better to tunnel under the slab or open the floor?
It depends on what you value more. Tunnelling from outside leaves your floors, cabinets and finishes untouched, which matters a great deal in a finished home — but it is the more expensive route because someone has to dig and shore that tunnel by hand. Going through the floor is cheaper and often faster, at the cost of opening and restoring the slab inside. On a vacant house or a make-ready, through-the-floor is usually the sensible call; in an occupied home with new floors, tunnelling frequently wins. We price both so the trade-off is yours to make.
Do I need a permit to replace my sewer line in Texas?
Yes — Texas municipalities require a permit for sewer line replacement, and most require the work to pass a city inspection before it's closed up. We handle pulling the permit and scheduling that inspection as a normal part of the job.
