Sewer line repair cost in Houston

Inspection and cleaning

Plenty of sewer problems end here: a jetting job and a clean camera pass, and no repair at all. The sewer line repair cost Houston homeowners fear is often a $600 cleaning once someone actually looks.

Repair and replacement by method

• Spot repair, yard, 2–5 ft deep$1,500–$3,000
• Spot liner, one section$1,500–$3,500
• Spot repair under concrete$2,500–$4,500
• Short under-slab tunnel$4,000–$9,000

Typical ranges, not a quote.

• Open trench, 30–50 ft$4,000–$8,000
• Open trench, 50–80 ft or deep$7,000–$12,000
• Open trench under driveway$9,000–$15,000
• Trenchless lining, full lateral$6,000–$12,000
• Pipe bursting, full lateral$7,000–$15,000
• Reroute around the slab$8,000–$20,000
• Long under-slab tunnel$12,000–$25,000

Typical ranges, not a quote.

Each row links to a page that explains the method: repair, replacement, trenchless, under-slab. For a full-line job, sewer line replacement cost by method goes row by row.

What moves the price

• Depth. Houston laterals are shallow — 2 to 5 feet on most lots — which is why Houston open-trench prices tend to sit below national figures. A lateral that runs 6 feet deep to reach a main under a wide street costs more in shoring and spoil.
• What is on top. Grass is cheap. A driveway is $1,500–$4,000 of demolition and re-pour. A pool deck, a retaining wall or a big live oak's root zone pushes the job to trenchless.
• Length. Inside the Loop, 30–50 feet is typical. Memorial, Spring Branch and Kingwood lots can run 80–120 feet.
• Access. A cleanout at the house saves $600–$1,500 up front and makes every future visit cheaper. Most pre-1980 Houston homes do not have one.
• Material. Cast iron is heavier to remove and often means the under-slab section is failing too. Orangeburg means a full replacement, no exceptions. An offset joint in old clay is its own case — see offset joints in clay pipe.
• Restoration. Sod, sprinkler repair, concrete and landscaping are separate lines, and they should be on the estimate rather than the invoice.
• Permit and inspection. $100–$300 in the City of Houston, similar in the suburbs, listed as its own line.

A worked example

A 1972 house in Westbury, 45-foot lateral, 3 feet deep, ABS with two offset joints and roots, under grass with a sprinkler line crossing it. Camera and locate $350; open-trench replacement in schedule 40 PVC with a new cleanout, permit and inspection $6,200; sprinkler repair and sod $450. Total about $7,000, two days. The same house with the lateral under a stamped-concrete driveway would be a lining job at about $8,500 and one day, because the driveway would cost more to replace than the price difference. These are illustrative figures built from the typical ranges above, not a quote.

Ways to keep the bill down

• Get the camera first. A few hundred dollars up front is what stops a replacement being sold for a jetting problem.
• Add a cleanout if you have none. It pays for itself on the second visit, because nobody has to pull a toilet.
• Fix the section, not the line, when the footage allows it. One offset joint is a spot repair.
• Combine jobs that share a trench. If the water service is failing too, one trench for both is cheaper than two.
• Ask about timing. Some companies are slower in late winter than in root season, and a non-urgent job can be scheduled then. Ask; do not assume a discount.
• Read the restoration lines. Doing your own sod can save a few hundred dollars. Ask before the job, not after.

Costs people forget to budget for

The repair is rarely the only line. Plan for the camera visit, a cleanout if the house has none, the permit, sprinkler repair where a trench crosses the system, sod or seed, and concrete if a walk or driveway is cut. On slab homes, add a hydrostatic test after the work if the slab was involved. If the home flooded or backed up, there may be cleanup and drywall inside the house, which is a separate trade. A quote that lists all of these is easier to trust than one that lists none.

When to get a second opinion

A second camera visit costs a few hundred dollars. It is worth it when the first quote is for a full replacement or a long tunnel, when the price is well above the ranges on this page, or when you were not shown the footage. Ask the second company to look without telling them the first number. If both see the same thing, you can hire with confidence.

Reading a Houston sewer quote

A real quote lists the method, the footage, the depth, the pipe material, whether a cleanout is included, the permit, the restoration, and any warranty terms. It comes with the camera footage the quote is based on. Things that should make you get a second opinion:

• A replacement quoted without a camera inspection, or with one you were not shown
• One number, no line items
• A "today only" price, or a large deposit before the permit is pulled
• Tunneling quoted for the whole house when the hydrostatic isolation found one leaking run
• No Responsible Master Plumber license number on the paperwork — Texas requires a licensed plumber for this work, and you can check the number on the TSBPE website

The average cost of sewer line repair in Houston goes deeper into three real-world scenarios, and sewer inspection before buying a house covers how to use a quote in a negotiation. Sewer line insurance Houston homeowners are sold — the utility-line protection plans that arrive in the mail — is covered on the about page, and it is worth reading before you rely on one.
