How Long Does Sewer Line Replacement Take?

HomeGuide lists 1–5 days to replace or repair a sewer line, depending on length and what sits in the way. Trenchless work is the short end of that band. A traditional dig is the long end, and Angi says that dig can run more than a week. Prices for the job itself are on the sewer line replacement cost page. This page is the calendar.

You usually can stay in the house. You can't send water down the drains while the lateral is open. No toilets, no laundry, no showers until the new pipe is connected and tested.

How long sewer line replacement takes by method

HomeGuide's 1–5 day range already includes trenchless work and digging. It says trenchless replacements take less time than trenching. We'd rather leave that blank than print a dig-only day count HomeGuide never published.

Trenchless sewer line replacement uses two small pits, or a cleanout, instead of a trench across the yard. Pipe bursting pulls in HDPE, a flexible plastic pipe, and breaks the old pipe outward. Lining, CIPP, cures a resin liner inside a pipe that is still round. Bursting doesn't wait on a cure. Lining does.

What those days don't include

Permits, city inspections, and utility locates sit on top of crew time. Call 811 before anyone digs so gas, electric, and water get marked. Weather, a frozen trench, or work in the street can add days the bid didn't show as “pipe work.” Angi notes that a traditional job may close a street for equipment.

A camera inspection at $100–$500 should happen before the method is chosen. Doing it after the trench is open is how a lining plan turns into a multi-day dig.

Restoration is its own clock. The pipe can be in use while the driveway patch is still on a contractor's schedule. Sewer line repair is shorter when the camera shows one joint instead of a dead run.

Living in the house

You'll lose your drains while the crew is working. The permit wait before that doesn't affect them. Bottled water, a paused dishwasher, and a neighbor's laundry room get you through a one-day lining job. A dig that runs several days is harder. Ask the bidder, in writing, when the line will be usable again and whether overnight caps are part of the plan.

If sewage has already entered the house, cleanup is a different duration. HomeGuide puts a simple sewage cleanup at 1–3 days and a large restoration at 1–2 weeks. That clock starts when the water got in. It doesn't wait for the new lateral to be finished.

Worked example

A 50-foot suburban lateral. The camera shows a collapsed clay run, which rules out lining, so the crew plans to burst it.

HomeAdvisor's trenchless window is 1–3 days of crew time. HomeGuide's overall band is still 1–5 days. Put both on the bid: “pipe work, 1–3 days; permit and inspection not included.”

If the same house had needed a trench under a driveway, Angi is the source for “over a week,” and restoration would continue after the toilets worked again. The dollars for that 50-foot bursting job, with a camera and a permit in a Midwest suburb, are about $7,700–$11,000. Time and money are separate lines.

How to save money

• Book the camera before you approve a method, so you aren't changing from lining to a dig mid-week.
• Ask for a written schedule: start day, day the drains work, day restoration ends.
• Call 811 early. Locates that arrive after the crew does are dead time you still pay for.
• If the city owns the stretch under the street, get that in writing so you aren't waiting on the wrong permit.
• Don't treat “one day” as a promise unless the bid names lining or bursting and the path is already filmed.
