When Does a Storm Drain Need Excavation?
Storm drain excavation is needed when water is not moving away from the property the way it should. That can mean a broken line, a catch basin that has settled, a downspout tie-in that has separated, or a line that was installed without proper fall.
Jetting and cleaning can clear a clog, but they cannot fix a collapsed pipe or a belly. If the problem keeps coming back after cleaning, the line usually needs to be exposed and repaired.
(720) 935-6221Signs a storm drain needs excavation
- Standing water that does not drain within a day of rain.
- Erosion or washout along the line path.
- A settled or cracked catch basin.
- Downspout water backing up at the foundation.
- A storm line that clogs repeatedly after cleaning.
How We Diagnose It
Is It a Clog or a Structural Failure?
A single clog after a heavy storm is usually debris. A line that clogs every season, holds water between storms, or shows settlement in the basin is more likely a structural problem that excavation will solve.
We scope private storm lines with a camera when access allows, and we excavate targeted sections to confirm what jetting cannot show.
How an Excavation Job Runs
- 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
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
Site Protection
Access route planned, surfaces protected, spoils staged, and tree protection observed where the canopy or root zone is regulated.
- 4
Careful Exposure
Around known crossings we vacuum excavate rather than dig blind. Paint on grass is an approximation, not a guarantee.
- 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
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.”
“They cleared our drain where Roto Rooter couldn't and quoted us to replace the line under our concrete.”
“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.
