Sewer Line Repair & Replacement in Portland & Southern Maine

The tell-tale sign is the lowest drain in the house backing up when water runs elsewhere — flush an upstairs toilet and the basement floor drain gurgles. Several slow drains at once and sewer odors also point to the lateral.

Outside, watch for a strip of lawn that stays soggy or unusually green, a sunken patch over the pipe run, or foundation cracks near where the line exits the house. A camera inspection confirms it in under an hour.

Sometimes. If the pipe is intact but root-choked, hydro-jetting or a root-cutting head restores flow without excavation. If there is one break or offset joint, a spot repair opens a single small hole rather than a trench.

A collapsed section, a bellied pipe holding water, or cast iron rotted through needs replacement. Trenchless lining or pipe bursting can avoid a full trench in some cases; depth, bends, and the host pipe condition decide whether they are options.

Sewer work is the widest cost range in plumbing. A single spot repair on an accessible section typically runs $1,500 to $4,000. Full replacement of a lateral from house to street runs from around $5,000 to $15,000 or more.

What moves it: depth (Maine laterals often sit four to six feet down to stay below frost), the length of the run, and whether the trench crosses a driveway, sidewalk, or city street.

Ground conditions matter too — ledge is common on the Portland peninsula and Munjoy Hill and turns a day of digging into two. Every sewer job gets a written quote after the camera inspection, before any excavation starts.

Day one is locating: Dig Safe utility marks, a camera and locator to trace the pipe path and depth, and permits filed. We tell you how long you will be without drains and schedule around it.

Excavation, new PVC pipe, and a new cleanout at the house take one to three days depending on depth and length. The inspector sees it before backfill; then we backfill, compact, and restore lawn, driveway, or sidewalk as quoted.

Stop running water — every flush and laundry load ends up on the basement floor. Keep people and pets out of standing sewage, use a floor-drain plug or backwater valve if you have one, and photograph damage for insurance.

Find your cleanout if you know where it is — usually a capped pipe in the basement near the foundation wall or outside close to the house. Clearing a path to it saves the crew time you are paying for.
