Trenchless sewer repair fixes damaged pipes without digging a trench across your yard or driveway. The two main methods — cured-in-place pipe lining and pipe bursting — require only small access points, which means your landscaping stays intact, the job finishes faster, and the new or rehabilitated pipe is often stronger and smoother than what it replaced.

No Trench Means No Landscape Destruction

The most immediate benefit homeowners care about is what doesn’t happen to their property. A conventional sewer excavation requires opening a trench the full length of the damaged pipe run — often from the house foundation to the city main at the street, which can be 50 to 100 feet or more. That means removing grass, garden beds, walkways, and in many cases cutting through concrete driveways or sidewalks. Trenchless methods require only a cleanout access point at one end and a small exit pit at the connection, leaving the yard and driveway between them untouched. In Denver’s older neighborhoods where mature landscaping has taken decades to establish, this difference is significant.

Faster Completion

Open excavation involves not just digging but shoring, backfilling in compacted lifts, waiting for concrete patches to cure, and surface restoration — often spread across multiple days or visits. A pipe lining job on a typical residential sewer run can often be completed in a single day. Pipe bursting takes longer due to the pull setup, but still completes faster than an equivalent excavation. Faster completion means less time with drain service interrupted and less disruption to daily life.

The Repaired Pipe Often Outperforms the Original

Epoxy liners used in cured-in-place pipe lining are rated for 50 years or more by most manufacturers. The smooth interior surface of a cured liner has less flow friction than original clay tile or cast iron and is continuous — no joints where roots can enter. HDPE pipe installed via pipe bursting is flexible, joint-free for long runs, and resistant to the corrosion and root intrusion that ends the life of older pipe materials. In both cases, the repaired or replaced pipe addresses not just the current damage but the vulnerability that caused it.

Handles Colorado’s Soil Conditions Well

Denver’s expansive clay soils are a primary reason sewer lines fail here — the ground moves seasonally and stresses pipe joints over time. HDPE pipe used in bursting is flexible enough to absorb minor ground movement without cracking, and a continuous epoxy liner eliminates the individual joints in old clay tile that are the first to fail when soil shifts. For Front Range homeowners, this means the trenchless repair is more durable in the actual soil conditions of the region than a conventional PVC open-cut replacement that introduces new joints in the same unstable ground.

Less Disruption to Home and Family

A full sewer excavation can mean days with limited plumbing use, construction equipment in your yard, and an open trench that presents safety concerns — particularly if children or pets are present. Trenchless repairs limit the work zone, keep heavy equipment to the access points, and restore drain service faster. For homeowners with mobility concerns, elderly family members, or small children, this reduction in the scope and duration of the work zone matters.

Cost Comparison With Open Excavation

Trenchless repair often costs less in total project cost than open excavation when surface restoration is factored in. Excavation estimates frequently exclude or understate the cost of concrete removal and replacement, sod or landscaping restoration, and paving work — costs that add up quickly on a full sewer run. Trenchless eliminates most of those restoration costs because the surface between the access points is never opened. Done provides written estimates that include all aspects of the project so you can compare accurately. Financing is available for larger sewer projects regardless of method.

  • No full trench — landscaping and hardscape between access points untouched
  • Faster completion, often in a single day for lining jobs
  • Epoxy liners rated 50+ years; HDPE pipe is joint-free and corrosion-resistant
  • HDPE flexibility handles Front Range clay-soil movement
  • Smaller work zone — less disruption, fewer safety concerns
  • Total cost often competitive once surface restoration is included in the comparison
