# Residential Excavation in Denver

Residential excavation in Denver covers sewer laterals, water services, drains, and septic work on single family and multi-family properties. Denver Sewer and Water protects landscaping, minimizes the trench footprint, and restores driveways, patios, and yards.

- Sewer and water line excavation for homes.
- Driveway, sidewalk, and yard restoration.
- Septic tank and drain field exposure.
- Trenchless alternative quoted when possible.
- Family-owned crews serving Denver neighborhoods.

## 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.

- Sewer lateral replacement or repair.
- Water service line leak or replacement.
- Septic tank, lid, or drain field work.
- Storm drain correction in the yard.
- New tap for an addition or accessory dwelling unit.

## 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. **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 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.

- Depth of the line and the shoring the trench requires.
- Soil conditions, groundwater, and rock.
- Surface being cut: turf, asphalt, concrete drive, or city street.
- Right-of-way permitting and traffic control requirements.
- Length of the run and the number of crossings in the way.

## Frequently asked questions

**Do you locate utilities before excavating?**

Always. Locates are requested and then verified on site. Around known crossings we expose utilities with vacuum excavation rather than digging blind. Paint on grass is an approximation of horizontal position, not a guarantee of depth.

**How much of the property gets torn up?**

It depends on the method the pipe supports. A full open cut replacement needs a trench the length of the run. A trenchless repair needs only access pits. We show the footprint on the site before the work starts.

**Do you restore the surface after excavation?**

Yes, to the specification for what was cut. Concrete is replaced with concrete, asphalt with asphalt, and turf is backfilled and compacted so the trench does not settle into a rut.

**Will you destroy my yard during excavation?**

We open only the area the repair requires and protect the rest. After the work is inspected, we backfill in lifts and restore sod, concrete, asphalt, or pavers to match what was there.

**Can you work in small Denver lots?**

Yes. We have compact excavators and hydro excavation equipment that fit tight lots, alleys, and narrow side yards common in older Denver neighborhoods.
