# How Long Does Sewer Line Repair or Replacement Take in Houston? Timelines by Method

*Published 2026-10-07 by Hugo Plumbing, Houston, TX.*

Sewer line repair timelines for Houston homes: hours for jetting, 1 to 2 days trenchless, up to 2 weeks under-slab tunneling, what adds time, when drains work.

The question comes right after "how much" and often matters more: **how long will my house be torn up?** For a sewer line in Houston the honest answer runs from a couple of hours to a couple of weeks, and the method, not the length of pipe, decides where you land. This guide lays out the realistic timeline for each repair method, what adds days to it, when your drains will and will not work, and how to prepare so the job finishes on schedule.

If you have not yet read about the methods themselves, our [trenchless vs. traditional](/blog/trenchless-vs-traditional-sewer-repair-houston) comparison explains what each one involves. This guide is about the calendar.

## Timelines by Method

| Method | Typical duration | Drains out of service | Restoration afterward |
|---|---|---|---|
| Hydro jetting + camera inspection | 2 to 4 hours | During the work only | None |
| Spot repair in the yard (dig one break) | Half day to 1 day | 1 to 3 hours at tie-in | Backfill, sod patch, same or next day |
| Sectional point repair (short liner) | Half day | 2 to 4 hours cure | None |
| Pipe lining (CIPP), full run | 1 to 2 days | 4 to 12 hours during cure | Access pit backfilled, if any |
| Pipe bursting | 1 to 2 days | 2 to 6 hours at tie-in | Two pits backfilled, sod or concrete patch |
| Traditional trench, yard to street | 1 to 3 days | Overnight at most, usually same-day tie-in | Backfill, grading, sod or driveway section, 1 to 2 added days if concrete |
| Under-slab tunnel, one section | 3 to 10 days | Until final tie-in, then a few hours | Tunnel backfilled and compacted, exterior landscaping |
| Full under-slab drain replacement | 1 to 2 weeks | Staged, a few hours per tie-in | Tunnels backfilled, interior access points patched |
| City tap / connection at the main | Adds 1 to 2 days | None beyond the main job | Street or right-of-way restoration per city requirements |

These are working-day ranges for a typical single-family Houston home with a 4-inch line and normal depth. A longer run, deeper pipe, or a line under a driveway, pool deck, or mature tree moves you toward the top of each range.

## What the Days Actually Look Like

### Before anyone digs: locates and permits

Texas law requires a utility locate request before excavation, and the markings take **two working days** to be completed after the Texas 811 ticket is filed. That means a repair diagnosed on a Monday is dug on Wednesday at the earliest, unless it qualifies as an emergency, in which case the locate is expedited and the crew can work the same day with extra care. The City of Houston plumbing permit is pulled by the licensed plumber, usually within a day or two, and an inspection is scheduled for after the pipe is in and before backfill.### Day one for a yard repair or bursting job

Crew arrives, confirms the locate marks, and opens the pits or trench with a mini excavator. The old pipe is exposed, cut, and either repaired or burst and replaced. For bursting, the new HDPE pipe was fused into one length the day before or that morning. The new line is connected at the house and at the downstream end, and the city inspector sees it open. If the inspector comes the same afternoon, backfill happens that day. If the inspection lands the next morning, the trench stays open overnight with safety fencing and your drains are already working on the new pipe.

### Lining day

The line is hydro jetted to bare wall and camera-checked in the morning. The liner is wetted out with resin and inverted or pulled in from the cleanout, then cured with hot water, steam, or UV. Cure time is the no-drain window, anywhere from four to twelve hours depending on the system and the length of the run. Branch connections are reopened with a robotic cutter, a post-repair camera confirms the result, and drains are released that evening. Longer or multi-branch runs push into a second day.

### A tunnel job

A tunnel is hand-dug from an access pit outside the foundation, horizontally beneath the slab, to the failed section. In Houston clay a two-person crew typically advances **two to three feet per hour**, shoring as they go. A 15-foot tunnel is roughly a day of digging; 30 feet is two to three. Once at the pipe, the repair itself takes a few hours, the inspector views it, and the tunnel is backfilled and compacted in lifts, which takes about as long as the dig did. Your existing drains keep working until the final tie-in because the old pipe stays live until the new section is ready to connect.

### Full under-slab replacement

Multiple tunnels or a long tunnel following the main run, with branch lines picked up along the way. Expect one to two weeks of a crew on site, usually working from the exterior so the inside of the house stays largely untouched. Drains are switched over in stages, so you lose a bathroom for a few hours at a time rather than the whole house for days. When the pipe is still round enough to hold a liner, lining the under-slab run from a cleanout replaces most of this with one to two days, which is why we camera every line before quoting a tunnel. Our [pipe bursting vs. pipe lining](/blog/pipe-bursting-vs-pipe-lining-houston) guide covers when under-slab lining qualifies.

## What Adds Time

- **Weather and saturated clay.** Houston clay turns to paste after a hard rain. Trenches slump, tunnels need more shoring, and compaction cannot be done properly in mud. A heavy rain mid-job can add a day or two of waiting.
- **Depth.** A main that is 3 feet down is a morning. One that is 7 feet down at the street end needs trench boxes, more spoil, and more time to put back.
- **Concrete.** Cutting a driveway, sidewalk, patio, or garage slab adds the cutting itself, then a separate pour and cure for the patch, typically one to three extra days before you can drive on it.
- **The city tap.** If the break is at the connection to the city main, work in the right-of-way needs its own permit, sometimes a traffic plan, and inspection coordination. Add one to two days.
- **Utility conflicts.** A gas service, water line, or communications conduit crossing the trench slows digging to hand work around it.
- **Tree roots and mature trees.** Root mass around a line slows the dig, and protecting a live oak's root zone can dictate hand excavation. See [tree roots in sewer lines](/blog/tree-roots-sewer-lines-houston).
- **Inspection scheduling.** Same-day inspections happen; next-morning is common. A trench that stays open overnight is normal and safe when fenced.
- **Surprises on camera.** A second break, a belly, or a collapsed section found once the line is open changes the scope. A thorough camera inspection before the quote is how those surprises get found ahead of time instead of mid-job.

## When Your Drains Will and Will Not Work

For most methods, you have plumbing at the start and end of every day. The no-drain windows are short and predictable:

- **Yard spot repair or bursting:** a few hours around the tie-in, usually midday.
- **Lining:** the cure window, four to twelve hours in a single block. Plan showers before the crew arrives and laundry for the next day.
- **Tunneling:** essentially none until the final tie-in, then a few hours.
- **Traditional trench:** tie-in the same day in nearly every case.

If a job must leave you without drains overnight, you should be told in advance. "You will be without drains from roughly 10 a.m. to 4 p.m. Tuesday" is the level of detail to expect in the written plan.

## How to Prepare the House

- **Clear the path.** Move vehicles off the driveway if it is in the work zone, and pull back anything in the yard along the pipe route: planters, furniture, grills, toys.
- **Mark what you care about.** Point out sprinkler heads, landscape lighting wires, and any plantings you want protected before the first shovel.
- **Find your cleanout.** The crew will need it for the camera and for jetting. If you do not have one, this job is the time to add it; see [how to find your sewer cleanout](/blog/how-to-find-your-sewer-cleanout-houston).
- **Plan the no-drain window.** Shower, run the dishwasher, and do laundry ahead of it.
- **Pets and kids.** Open trenches and tunnel pits are fenced, but the yard is a work site for the duration.
- **Access to the house.** Lining and camera work may need a toilet pulled or an indoor cleanout; someone 18 or older should be home for those parts.

## What the Written Quote Should Say About Time

A quote that only has a dollar figure is half a quote. Before you sign, it should state:

- The **method** and why the camera supports it.
- A **start date** that accounts for the 811 locate and the permit.
- The **expected duration** in working days, with the weather caveat.
- The **no-drain window**, if any.
- **Restoration**: who backfills, compacts, replaces sod, and repours concrete, and when.
- Whether the **city tap** and right-of-way work are included.
- That a **post-repair camera video** will be provided.

## Frequently Asked Questions

**How long does it take to replace a sewer line in Houston?**

It depends on the method. A spot repair in the yard is usually a half day to one day. Trenchless pipe lining or pipe bursting typically takes one to two days, including cure time for a liner. A traditional open trench across a yard runs one to three days. Under-slab work is the long one: tunneling to reach and replace a section usually takes three to ten days, and replacing all the drain lines under a house can take one to two weeks. Add two working days up front for Texas 811 utility locates before any digging.

**Can I use my plumbing while the sewer line is being replaced?**

Usually yes, with a short window where you cannot. For most yard repairs and bursting jobs, the line is cut over at the end of the day, so drains are back the same night. Pipe lining takes drains out of service for the cure, typically four to twelve hours in one block. Tunneling leaves the existing line working until the final tie-in. Your plumber should tell you the exact no-drain window before the job starts so you can plan showers and laundry around it.

**Why does a sewer repair take longer under the slab than in the yard?**

Access. In the yard an excavator opens a trench in an hour. Under a slab, crews hand-dig a tunnel from outside the foundation to the pipe, usually two to three feet per hour in Houston clay, shore it as they go, make the repair in a confined space, then backfill and compact. A 20-foot tunnel can take two to three days just to dig. Lining from a cleanout avoids the tunnel entirely when the pipe is still round, which is why the camera inspection comes first.

**How long does it take to get a sewer repair permit in Houston?**

For a residential sewer line replacement inside the City of Houston, the plumbing permit is typically pulled by the licensed plumber in a day or two, and the inspection is scheduled after the pipe is in and before backfill. Permit and inspection timing is the most common reason a one-day job becomes a two-day job. Hugo Plumbing includes the permit, the 811 locate request, and the inspection in the written price and builds that time into the schedule you are given.

**Does the sewer line have to be replaced all at once?**

No. If the camera shows one break or root intrusion in otherwise sound pipe, a spot repair or a short sectional liner fixes it in a day. If it shows failure along the whole run, a staged approach is possible but usually costs more than doing it once, because mobilization, locates, and permits repeat. The camera inspection, $295 to $350 at Hugo Plumbing, is what tells you which situation you have.
