What Kinds of Jobs Does This Cover?

A large share of our residential work is replacing an aging clay sewer lateral running under a mature parkway strip, where the roots of an old street tree have found every joint in the pipe over decades. That job means locating the line, camera inspecting it, deciding whether a trenchless method will work around established roots or whether excavation is required, and restoring the parkway once the new line is in.

On the water side, a common job is swapping a galvanized water service, now corroded and restricted, for a new copper or approved replacement line, often running under a driveway or a section of concrete that has to be cut and replaced. Storm drainage work frequently involves re-grading a run that has settled at a joint and stopped draining, which shows up as standing water after rain rather than a dramatic failure. Commercial work includes tapping a new fire line into a building for suppression system service, a job with its own permitting and inspection requirements separate from a domestic water tap.

Categories of work we regularly perform

  • Clay and cast iron sewer lateral replacement under lawns, parkways, and driveways.
  • Galvanized water service replacement with copper or an approved modern material.
  • Storm drain re-grading and repair where a run has settled and stopped draining.
  • Trenchless sewer repair where root damage or a break allows it.
  • Commercial fire line taps and connections for new construction and retrofits.
  • Sewer and water line excavation where trenchless methods are not a fit.
  • Drain camera inspection to find the cause of a recurring backup.

How We Diagnose It

How We Decide the Approach on a Job Like This

Every job in the categories above starts with a camera inspection or a locate, not a guess. On a lateral replacement, that means knowing where the pipe runs, how deep it sits, and what is above it before deciding whether trenchless repair is realistic or whether the parkway has to be opened. On a water service swap, it means confirming the existing line's material and path before cutting concrete.

The same discipline applies to storm and fire line work. A storm run that has settled needs its grade corrected, not just its blockage cleared, or the same call comes back next season. A fire line tap has to meet the requirements of the local jurisdiction and the fire authority, which we confirm before any excavation starts.

What we confirm before starting a job

  • Pipe material, depth, and condition from a camera or locate.
  • Whether trenchless methods fit the site conditions.
  • What is above the line: trees, hardscape, utilities, structures.
  • Permitting and inspection requirements for the specific work.
  • How to limit disruption to the property while the work is done.

How We Approach a Representative Job

  1. 1

    Take the call and hear the symptoms

    Backups, low water pressure, standing water, or a known old line prompt the first conversation.

  2. 2

    Locate and inspect

    Camera and locating equipment establish what is actually in the ground before anything is quoted.

  3. 3

    Choose the method

    Trenchless repair where the line and site allow it, excavation where they do not.

  4. 4

    Do the work

    The crew completes the repair or replacement according to the method chosen.

  5. 5

    Restore the site

    Landscaping, driveway, or hardscape disturbed by the work is put back as close to its original condition as the job allows.

What Drives Cost on These Job Types

Depth of the line, distance to be replaced, what sits above the pipe, and whether trenchless methods are an option all move the number on a lateral or water service job. A parkway with a mature tree over the line is a different job than open lawn with nothing above it.

On storm and fire line work, access and the scope of grading or connection required drive cost more than the length of pipe involved. We do not price representative work on this page because every property is different, and the categories above exist to describe method, not cost.
