Excavation Services in Columbus, Ohio
Excavation is the open-cut method for installing, replacing, and repairing sewer and water lines when trenchless lining or pipe bursting is not the right call. Wooley Water Sewer Trenchless has been digging across the Columbus, Ohio metro since 1978 — running our own owned fleet of excavators, mini-ex, and dump trucks, pulling permits with Columbus Public Health, Franklin County, and the surrounding municipalities, and restoring every surface we open. We do the digging when digging is the right answer, and we say so when it isn't.
What Excavation Work Actually Is
Excavation — also called open-cut work or trenching — is the traditional approach to underground sewer and water service: dig a trench from the structure to the city main, lay or replace the pipe in a properly graded bed, pressure-test or camera-verify the new run, then backfill and restore the surface. It is the oldest method in the trade and it is still the right answer for an entire class of jobs that trenchless cannot handle.
At Wooley, excavation is roughly one-third of what we do. The other two-thirds — CIPP pipe lining and pipe bursting — are the reasons most people find us. But when a pipe is fully collapsed, severed by a contractor's auger, missing entirely (new construction, ADUs, additions), or hidden behind a service that is itself failing, the trenchless tools cannot work and the trench is the right tool.
We dig because we want the right method on every job, not because every job looks like a nail. The crew, the equipment, the permit relationships, and the surface-restoration discipline are the same crew that's been doing trenchless work for the last two decades — applied to a different toolset.
When Excavation Is the Right Method
Excavation is the correct method when trenchless cannot work, when there is no host pipe to line or burst, or when the surface conditions favour an open cut over an entry-and-exit pit pair.
No existing pipe to line or burst — new construction, ADUs, additions, or properties that never had a lateral or water service.
Fully collapsed pipe — when the host pipe has lost its cross-section, CIPP cannot support the cure pressure and bursting may not have a clear pull path.
Severed water main from a contractor's auger, fence-post auger, or directional drill — the line is in two pieces and needs to be reconnected.
Isolated spot failure — a single 6-foot section of pipe is bad and the rest is fine; a targeted dig is cheaper than relining the entire run.
Material transitions that trenchless tools can't bridge — clay to cast-iron, lateral-to-stack, or non-standard fittings that need a hand-built repair.
Water service installation — water lines are usually shallow enough and short enough that open-cut is faster and cheaper than mobilising trenchless equipment.
Surface conditions favour the cut — an open yard with no mature landscape, an existing torn-up driveway already scheduled for replacement, or a site where the surface will be redone anyway as part of a larger renovation. The trench becomes the cheaper path when restoration is already in the scope.
The honest test: if Wooley can solve your problem with trenchless work and save the yard, we'll quote it that way. Our trenchless sewer repair hub walks through method selection. If trenchless isn't right, this hub explains the open-cut path.
The Three Excavation Services We Offer
Wooley's excavation work breaks cleanly into three service lines. Each has its own page with detailed cost ranges, process steps, and code requirements.
Sewer Line Installation
New sewer lateral installed from the structure to the city main. New construction, ADUs, room additions, and homes that were never connected. PVC SDR-26 or SDR-35 per Ohio Plumbing Code, pressure-tested, camera-verified. Typical range $5,500–$15,000.
Water Line Installation
New domestic water service from the meter pit or city tap to the house entry. Type-K copper, HDPE, or PEX depending on jurisdiction. Buried below Ohio's 48-inch frost depth, pressure-tested at 100+ PSI, chlorination certificate per code. Typical range $3,500–$8,000.
Sewer & Water Line Repair
Targeted open-cut repair for fully collapsed laterals, severed mains, and isolated spot failures where trenchless methods cannot be used. Pre-camera diagnostic, sonde locator, access pit, splice with matched fittings, surface restoration. Typical range $2,500–$8,000.
Our 9-Step Excavation Process
Every Wooley excavation — install or repair, sewer or water — runs through the same nine-step sequence. The order is fixed; the schedule is whatever the jurisdiction's inspector allows.
Permit pull
We pull the permit in the property owner's name with the right jurisdiction — Columbus Public Health for Columbus and Bexley, Franklin County Public Health for unincorporated Franklin, and the corresponding county health department elsewhere. Right-of-way permits where the trench crosses public property are filed separately with the municipal engineer.
Utility locate (OUPS 811)
Ohio Utilities Protection Service (OUPS) 811 ticket filed at least 48 hours before the dig. Gas, electric, telecom, and water mains are flagged on the surface. We do not break ground until every utility on the ticket has cleared.
Surface protection & staging
Plywood pathways protect lawn from track damage. Spoil pile location is staged on tarps. We document the pre-existing condition of every surface that will be opened or driven over — concrete, pavers, fence lines, hardscaping — before the first bucket moves.
Trench excavation
Mini-ex for tight residential lots, full-size excavator for longer runs and commercial work. Trench width is sized to the pipe diameter plus working clearance per OSHA shoring requirements. Depth follows the existing pipe (for repair) or local code minimums (for new install). Spoil is set well clear of the trench edge.
Pipe bedding
Compacted sand or pea gravel bedding, 4 to 6 inches under the pipe, properly graded at 1/4 inch per linear foot for gravity sewer or below frost line for water. Grade is the make-or-break detail — a poorly bedded pipe will belly and back up regardless of the pipe's condition.
Lay or repair pipe
Sewer: PVC SDR-26 or SDR-35 with rubber-gasket joints, glued where the jurisdiction requires it. Water: Type-K copper, HDPE with electrofusion fittings, or PEX depending on the city. Fittings matched to the existing material at every transition.
Pressure or camera test
Water lines pressure-tested at 100+ PSI and held for the duration the jurisdiction requires (typically 15 minutes to one hour). Sewer lines camera-scoped end-to-end and, where required, low-pressure air-tested. Test results documented for the inspector.
Municipal inspection
Health department or building department inspector visits the open trench before we backfill. Some jurisdictions allow video walkthrough; most still require an on-site inspection. We do not backfill until the inspector signs off. If the inspector flags something, we fix it on the spot.
Backfill & surface restoration
Backfill in lifts — 12-inch compacted layers — to prevent settlement. Topsoil, seed, and straw mulch on lawn restorations. Concrete or asphalt patch for driveways and sidewalks (subcontracted to a paving partner where the scope warrants). Final walkthrough with the property owner before we leave site.
What Excavation Work Costs in Columbus
Columbus-metro excavation ranges for residential and light-commercial work. Final pricing always quoted in writing after a site visit — never a phone estimate, never a markup on materials.
Type-K copper, HDPE, or PEX. 48-inch frost depth. Chlorination certificate.
Single failure point, surrounding pipe intact. Access pit, splice, backfill.
When trenchless is not viable. Yard restoration included.
Cost factors: trench length, depth (water lines run 48" minimum, sewer follows existing depth), surface type (lawn, driveway, sidewalk, asphalt), permit jurisdiction, soil conditions (clay vs. fill vs. rock), and complexity of any tie-in or fittings. Permit costs run $85–$450 across Columbus and the surrounding suburbs — quoted line-item, never marked up.
| Surface Restoration Type | Typical Add | Notes |
|---|---|---|
| Lawn (topsoil + seed + straw) | Included | Re-seed at season; ~30-day grow-in |
| Concrete sidewalk patch | $450–$1,200 | Subcontracted; matched to existing |
| Asphalt driveway patch | $700–$2,400 | Cure-and-restore per municipal spec |
| Stamped concrete or pavers | Project-priced | We salvage and re-set where possible |
Permits, Code, and Inspection Sequence
Every excavation job in Central Ohio is governed by the Ohio Plumbing Code, the local health department, and — where the trench crosses public property — the municipal right-of-way office.
Ohio Plumbing Code — OAC 4101:3 governs material, slope, depth, and inspection requirements for sewer and water service. Wooley installs to code on every job, no exceptions.
Columbus & Bexley — Columbus Public Health issues sewer and water service permits inside Columbus city limits, including Bexley. Sewer-lateral permits are typically $150–$285.
Franklin County (unincorporated) — Franklin County Public Health covers unincorporated areas and some smaller jurisdictions. Different permit fee structure, similar inspection sequence.
Other counties — Fairfield County (Lancaster, Pickerington), Pickaway County (Circleville), and Delaware County each maintain their own health departments. Wooley pulls permits in all of them as part of standard project setup.
Right-of-way permits — when the trench crosses a sidewalk, curb, or roadway, a separate ROW permit is required from the municipal engineering office. Traffic-control plans, sidewalk closure notices, and pedestrian routing are submitted with the application.
Inspection sequence — open-trench inspection before backfill (mandatory for most jurisdictions), pressure-test verification (water), camera-scope or air-test verification (sewer), and final restoration sign-off. Wooley schedules and meets every inspection.
Where We Excavate
Wooley's 25-mile dispatch radius from Carroll, OH covers the full Columbus metro and the surrounding county seats. Sewer and water installation, lateral replacement, and spot repair are performed across the entire service area.
Excavation Work — Frequently Asked Questions
How long does an excavation job take in Columbus?+
A typical residential spot repair is one working day on site once the permit is pulled and the locate clears. A full lateral replacement or new install is two to four working days on site, plus inspection scheduling. Permit and OUPS-locate lead time adds 3 to 7 business days before the dig starts. Larger commercial scopes run on their own schedule and are quoted with a written timeline.
Do you handle the permit pull?+
Yes — permit-pull is included in every Wooley excavation quote. We file with the correct jurisdiction (Columbus Public Health, Franklin County Public Health, or the corresponding county / city office), pay the fee at submission, and pass the cost through line-item on the invoice with no markup. Right-of-way permits where the trench crosses public property are handled the same way.
What surface restoration is included in the quote?+
Lawn restoration — topsoil, seed, and straw mulch — is included on every job. Concrete sidewalk patches and asphalt driveway patches are quoted line-item; we coordinate with a paving partner where the spec requires it. Stamped concrete, pavers, and decorative landscaping are project-priced and discussed at the site visit. We never quote a job without putting restoration scope in writing.
Can you work on tight Bexley lots?+
Yes. Our mini-ex fits through a standard 36-inch gate and turns inside a 12-foot working corridor. We have excavated on hundreds of Bexley properties with mature trees, side-yard easements, and very narrow access. When the access is genuinely impossible for the mini-ex, we have hand-dug short runs (typically <10 feet) rather than damaging the property.
How deep do you dig for water vs. sewer lines?+
Water lines: minimum 48 inches below grade in Ohio — that is the published frost-depth requirement. We typically install at 54 inches to give a buffer. Sewer lines: depth varies by the existing connection point. New laterals tie into the city main at whatever depth the main runs (usually 6–10 feet), then rise toward the structure at the code-required 1/4-inch-per-foot slope. We confirm depth on the site visit before quoting.
