Sewer line repair
Sewer line repair in Houston: a homeowner's guide
Most Houston sewer problems are one bad section in a line that is otherwise fine. A good contractor finds that section with a camera, opens the ground only there, replaces it in PVC and puts the yard or the slab back. This guide to sewer line repair in Houston explains what breaks, how the repair goes, and what it should cost, and you can get a written price before anything is dug.
What actually breaks in a Houston sewer line
Cast iron under the slab, 1950s–1970s. The drains cast into the slab of a Meyerland, Bellaire, Oak Forest or Westbury ranch have been sitting in wet gumbo clay for sixty years. The bottom of the pipe rusts out first — channel rot — so the camera shows a flat, rough floor where the pipe should be round, then a gap where the hub let go. Water leaks into the clay, the clay swells under that part of the slab, and a foundation crew ends up finding the leak with a hydrostatic test. Repair here is a short tunnel from the outside of the slab to the bad hub, covered on the under-slab sewer repair page.
Separated joints in the yard. From Sharpstown to Katy to Pearland, the 1970s–90s yard laterals are PVC or ABS, and they were fine until the clay pulled the joints apart. Two or three inches of offset at a coupling is enough to catch paper, then roots. This is the classic sewer lateral repair Houston homeowners need: one dig, one section, usually done in a day. Offset joints in clay pipe covers the older clay version of the same failure.
Bellies. A low spot in the run where the clay settled under it. Water and solids sit there, and the line clogs every few months no matter how often it is snaked. A short belly is a spot repair — re-bed that section on compacted bank sand at the right fall. A long one is a replacement conversation.
Root intrusion. Live oaks in Braeswood and River Oaks, pecans in Garden Oaks, water oaks and Chinese tallow everywhere else. Roots do not break a sound pipe; they find a joint that has already opened. Tree roots in sewer line Houston-wide are a symptom: the roots get cleared, the joint they came in through gets a camera, and that joint gets repaired, or the roots are back by next summer.
Collapsed sections. When cast iron finally gives up or a crushed line under a driveway lets soil in, nothing gets through. Collapsed sewer line repair in Houston usually starts with getting the house draining, then a permitted replacement of that run.
How a spot repair usually goes
- Camera inspection through the cleanout. If the house has no cleanout — common on pre-1980 homes — the plumber will pull a toilet or add a cleanout first, which you will want anyway.
- Sonde locate. The camera head carries a transmitter; the break gets marked on the surface with paint and its depth noted.
- A written price for the repair, with the depth, the permit and the restoration listed.
- A Texas811 locate request for gas, water and cable, then the dig — typically a 4-by-6-foot hole to the pipe, which in most of Houston is only 2–5 feet down.
- The bad section is cut out and replaced with schedule 40 PVC on proper couplings, bedded in bank sand.
- City of Houston plumbing inspection with the trench open, then backfill, compaction and the grass put back.
- A second camera pass. Ask for the recording.
Most yard spot repairs are one working day. Under-slab spot repairs through a tunnel are two to three.
When repair is the wrong answer
The sewer pipe repair Houston homeowners ask for is sometimes not what they need. If the camera shows three or more separated joints, cast iron with channel rot along its whole length, or a belly longer than 10 feet, patching one spot buys a few months and you will be paying again. Ask to see the footage and the math. The replacement page covers the whole-line options, and trenchless covers the case where digging is not realistic.
Hydro jetting first, sometimes
When the camera shows grease, scale or a root mass in a pipe that is otherwise intact, the fix is cleaning, not surgery. Hydro jetting Houston kitchens and laundry lines need runs water at 3,000–4,000 psi through the line and scours it back to bare pipe wall, which a cable never does. It is $350–$900 and it is the right first step on a main sewer line clog Houston homes get every year from a mature oak. Jet, camera again, and only then talk about a repair if the pipe itself is damaged. Hydro jetting vs. snaking explains the difference. If every drain in the house is slow right now, start with how to spot and clear a main-line clog. A contractor who quotes a repair without a camera has skipped the part where they find out what is wrong.

Typical market ranges, not a quote. The pricing page has the rest. If you searched for sewer line repair near me, Houston-wide the number that matters is depth and what is on top of the pipe, and the camera shows both.
Choosing who does the repair
Every Houston sewer line repair that replaces pipe is permitted plumbing work, so the company doing it needs a Texas plumbing license under a Responsible Master Plumber. Ask for the number and check it on the TSBPE website. Compare quotes line by line — method, footage, depth, permit, restoration — rather than by the total, and be wary of any drain and sewer repair offer that needs an answer on the doorstep.
Neighborhoods
In practice, the sewer line repair Houston, TX homeowners need clusters where the housing is oldest or the clay moves most: Meyerland and Braeswood after a foundation job, Bellaire tear-downs that kept the old lateral, Oak Forest under the pecans, Sharpstown and Westbury on 1960s cast iron, and the 1980s stock in Sugar Land, Katy and Cypress. See the Bellaire and Sugar Land pages, and signs of a broken sewer line if you are still deciding whether to call.

How long does a sewer line repair take?
A yard spot repair is usually one day including the inspection. A repair under a driveway is one to two, because the concrete has to be cut and poured back. A short tunnel under the slab is two to three days. Ask the contractor to get the house draining at the end of each day so you are not without plumbing for the whole job.
Can a sewer line be repaired without digging up the yard?
Sometimes. A single cracked section with sound pipe on both sides can be spot-lined from the inside — a short sleeve cured in place — for $1,500–$3,500. If the joint has offset more than an inch or the pipe is crushed, the liner cannot bridge it and the section has to be dug. The camera shows which.
Do I need a permit for a sewer repair in Houston?
Yes. Replacing any section of the building drain or lateral is permitted plumbing work in the City of Houston and most of the suburbs, and the inspector looks at the pipe before the trench is closed. The licensed plumber doing the work pulls the permit, and it should be on the estimate as a line item, usually $100–$300.
Why does my line keep clogging even after it is snaked?
Because the cable clears a hole through the blockage and leaves the cause — an offset joint, a belly or a root mass. If a line has been snaked twice in a year, the third call should be a camera inspection, which usually finds one bad section that a spot repair fixes for good.
