The camera inspection determines which method is right for your line. We recommend whichever is appropriate — not whichever is more expensive.
Open-cut sewer replacement means excavating a trench along the full length of the lateral, removing the old pipe, installing new pipe, and restoring the surface. Trenchless replacement achieves the same result — a new, functioning pipe from house to main — without a full-length trench. Two access pits are dug at each end, and either a new pipe is pulled through the old one (pipe bursting) or a new liner is cured inside it (CIPP). The surface between the access points stays intact.
Neither method is universally better. The correct choice depends entirely on the condition of the existing pipe, its depth, its path, and what's above it. The camera inspection makes the determination.
Trenchless is appropriate when the line is deteriorated but structurally passable — meaning a bursting head or liner can travel through the full length. This rules out complete collapses, severe misalignment (horizontal or vertical), and pipes with obstructions that cannot be cleared. For all other cases, trenchless offers significant advantages.
The primary benefit is surface preservation. In Denver, many sewer laterals run under finished concrete driveways, mature landscaping, or decorative hardscape. Open-cut through a concrete driveway requires cutting, full excavation, pipe installation, compaction in lifts, and concrete restoration — a process that adds $2,000–$6,000 and multiple days to the job. Trenchless eliminates that cost and disruption entirely.
Job duration is also shorter. Most residential trenchless jobs on a standard 60–120 foot lateral complete in a single day. Homeowners have a functioning sewer by end of day rather than living without drain use for 2–5 days during open-cut work.
The new pipe installed by trenchless methods is also excellent. HDPE pipe used in pipe bursting is rated for 100+ years. CIPP liner produces a jointless, seamless interior that is highly resistant to root intrusion. Both methods require permits and final inspection.
Open-cut is required when the pipe condition prevents trenchless equipment from doing its job. A fully collapsed section means a bursting head cannot pass through. Severe vertical or horizontal offset means a liner cannot follow the pipe path. Orangeburg pipe — a tar-and-paper composite installed in Denver from the roughly 1940s to 1970s — is too fragile to burst and too irregular to line reliably; open-cut is typically the recommended approach for Orangeburg.
Open-cut is also sometimes preferable when the lateral is very shallow, when the trench must be excavated anyway for another reason (like a utility conflict), or when soil conditions above the pipe make access pits impractical.
The tradeoff is disruption. A full-length trench through a finished yard means weeks before grass recovers. Concrete or asphalt must be saw-cut, removed, and poured back. Compaction and settlement take time. Total job duration is typically 3–5 days for a standard residential lateral, with surface restoration sometimes handled separately.
| Factor | Trenchless | Open-Cut |
|---|---|---|
| Cost (full lateral) | $4,000 – $12,000 | $6,000 – $18,000 |
| Timeline | 1 day | 2–5 days |
| Yard disruption | 2 access pits only | Full-length trench |
| Surface restoration | Minimal | Concrete, asphalt, or landscaping |
| Pipe lifespan | 50–100+ years | 50–100+ years |
| Eligibility | Requires passable pipe path | Works on any pipe condition |
| Permit required | Yes | Yes |
Trenchless pipe bursting: $4,000–$9,000 for a standard 60–120 foot lateral. CIPP lining: $4,500–$12,000 depending on diameter and length. Open-cut replacement: $6,000–$18,000 including excavation and surface restoration. When comparing options, always get total project cost — pipe + excavation + permits + restoration — rather than per-foot pipe cost alone. The trenchless premium often disappears when restoration costs are included.
Trenchless is especially advantageous in established suburbs where sewer laterals run under finished driveways and mature yards. In Lakewood, many homes built in the 1960s–80s have clay laterals under concrete driveways — trenchless eliminates the costly driveway restoration that open-cut requires. Aurora spans a wide age range; older neighborhoods near Colfax benefit most from trenchless, while newer east Aurora homes may have shallower lines where either method works well. In Parker, longer laterals on larger lots make the per-foot cost comparison especially relevant — the camera determines which method fits.
The camera inspection determines method eligibility. If the line is a trenchless candidate, we present both trenchless and open-cut options with pricing for each, and you choose. If the line is not a trenchless candidate, we explain why on video and recommend open-cut. No method is recommended without camera evidence to support it.

Learn more →Trenchless is better when your line is a good candidate — meaning it is deteriorated but not completely collapsed, and the pipe path does not have severe misalignment. The main advantages are minimal disruption to your yard, driveway, and landscaping, and a faster job. Open-cut is sometimes the only correct answer when the line is fully collapsed, badly misaligned, or at a grade or depth that trenchless equipment cannot handle. A camera inspection determines which applies.
Trenchless pipe installation costs more per linear foot than open-cut pipe installation — typically $80–$200/ft for trenchless versus $50–$120/ft for open-cut pipe work alone. However, open-cut requires excavation, backfill, compaction, and surface restoration (concrete, asphalt, landscaping) that can add $3,000–$8,000 to the job. When total project cost is compared — including restoration — trenchless is often competitive and sometimes cheaper, especially where the lateral runs under a finished driveway or mature landscaping.
Most trenchless pipe bursting or CIPP lining jobs on a standard residential sewer lateral complete in one day. Open-cut replacement typically takes 2–5 days for excavation, pipe installation, backfill, and initial surface restoration, with final concrete or asphalt restoration sometimes scheduled separately.
Open-cut is required when the existing pipe has completely collapsed and a bursting head cannot pass through, when there is severe misalignment that would prevent a liner from following the pipe path, when the pipe is Orangeburg (tar-paper composite) that is too fragile to burst, or when the lateral is too shallow for trenchless equipment access. A camera inspection identifies these conditions before any method is proposed.
Yes. Both trenchless and open-cut sewer lateral work requires permits and final inspection in Denver and most metro municipalities. Oh Drain It handles all permit pulling, utility locates, and inspection scheduling as part of the job.
