When Does a Home Need Excavation?

A home needs excavation when the sewer, water, drain, or septic line has failed in a way that cannot be fixed from the surface. Common triggers are repeated backups, a water leak under the yard, a soggy drain field, or a sinkhole opening along the line path.

We understand that the yard matters. Our goal is to open the smallest area that lets us do the repair correctly, then put the surface back the way we found it.

How We Diagnose It

Trenchless or Open Cut for a Home?

We prefer trenchless when the pipe is intact and the slope is good because it preserves landscaping and hardscape. We recommend open cut when the pipe is collapsed, the slope is wrong, or the connection at the main has to be exposed.

The recommendation is based on the camera and the grade, not on what is easier for us.

How an Excavation Job Runs

  1. 1

    Camera and Locate

    We scope the line, grade it, and mark depth and defect locations. Utility locates are requested and verified on site before any equipment moves.

  2. 2

    Permits and Traffic Control

    Sanitary review, right-of-way permits, and a traffic control plan where the street requires one. We carry these rather than handing them to the owner.

  3. 3

    Site Protection

    Access route planned, surfaces protected, spoils staged, and tree protection observed where the canopy or root zone is regulated.

  4. 4

    Careful Exposure

    Around known crossings we vacuum excavate rather than dig blind. Paint on grass is an approximation, not a guarantee.

  5. 5

    Excavate, Shore, and Repair

    The trench is opened and shored to depth, the pipe is replaced or the connection is made, and the work is inspected before it is covered.

  6. 6

    Backfill and Restoration

    Compacted in lifts to the spec for the surface above, then the surface is restored to what was cut, including concrete, asphalt, and landscape.

What Denver Customers Say About Working With Us

Very direct and to the point. Extremely efficient and professional.
Sam Hayden
They cleared our drain where Roto Rooter couldn't and quoted us to replace the line under our concrete.
Jason Gold
Prompt service and worked well into the night to restore service due to hard soil. And did their best to prevent large scars to the yard

What Drives Excavation Cost?

We will not put a number on this page, because excavation pricing is driven by conditions we have to see first. Depth is the single largest driver, followed by what is above the pipe and what has to be put back.

The honest version is that a shallow lateral in an open back yard and a deep connection under a concrete street are the same pipe and very different projects. We quote after the scope and the locate, not before.
