Trenchless Sewer Repair in Denver, CO
Apex Underground performs trenchless sewer repair in Denver using Horizontal Directional Drilling (HDD) and pipebursting, without digging up your lawn, removing your driveway, or destroying your landscaping. Based in Arvada and serving the entire Denver metro, our employee-owned team has been handling underground infrastructure work on the Front Range for 40+ years. We’re available 24 hours a day, 7 days a week, including same-day emergency response for active sewer failures.
What Is Trenchless Sewer Repair, and Why Does It Matter for Denver Homeowners?
Trenchless sewer repair is exactly what it sounds like: a method of repairing or replacing a damaged sewer line entirely underground, without cutting open trenches across your yard or pulling up your concrete. Where traditional open-cut excavation requires heavy equipment to dig a trench the full length of your sewer lateral, trenchless methods work from two small access points at either end of the line. The pipe is repaired or replaced underground, and your property stays intact.
This matters more in Denver than people often realize. Many of the city’s most beloved neighborhoods, including the Highlands, Park Hill, Wash Park, Capitol Hill, and similar areas built out in the early and mid-20th century, are still running on original clay tile or cast-iron sewer laterals that are reaching or past the end of their service life. When those lines fail, a traditional open-cut repair in an established yard with mature landscaping, root systems, and hardscaping can add thousands of dollars in restoration costs on top of the repair itself. Trenchless eliminates that additional damage entirely.
Apex Underground uses two primary trenchless methods to repair and replace failing sewer lines: Horizontal Directional Drilling (HDD) and pipebursting. Each method is suited to specific conditions, and our team selects the right approach based on your pipe’s condition, depth, material, and site layout.
Apex Underground's Trenchless Methods: HDD and Pipebursting
Horizontal Directional Drilling (HDD)
Horizontal Directional Drilling is a steerable underground boring method. A drill head is guided along a precise path beneath your yard, driveway, or landscaping, and once the bore path is established, the new pipe is pulled back through the bore hole into place. The result is a fully installed pipe with no surface disturbance along the path.
HDD is particularly well-suited for sewer lateral replacement and water service line installation in situations where the new pipe must pass under a driveway, a foundation, mature tree root systems, or other obstacles that would make open-cut excavation especially destructive or technically complex. It’s also the preferred method when there isn’t a usable existing pipe to work from, such as in new service installations or when the old pipe has already collapsed.
The Apex Underground team uses advanced HDD equipment that allows us to work in tight urban lots and challenging Denver-area soil conditions alike. Bore paths can be drilled with precision to navigate around utilities, structural elements, and other underground obstructions that a standard excavation would simply destroy.
Pipebursting
Pipebursting takes a different approach. Instead of drilling a new path, a hydraulically powered bursting head is pulled through the existing damaged pipe. As it travels through, it fractures the old pipe outward into the surrounding soil while simultaneously pulling a new pipe into the space the old pipe occupied. The old line is replaced in place, without excavation.
Pipebursting works best when the existing pipe is still intact enough to guide the bursting head through, even if it’s cracked, root-infiltrated, or otherwise failing. It’s an efficient method for replacing deteriorated clay or cast-iron sewer laterals in older Denver properties and typically results in minimal surface disturbance at the two access points. HDD is the better choice when there is no usable path through the existing pipe, or when a new route is needed entirely.
Both methods deliver the same outcome for you as the property owner: a repaired or replaced sewer line, a functioning system, and a yard that looks essentially the same as when we arrived.
Signs Your Denver Sewer Line Is Failing and When to Call
- Recurring drain backups throughout the house, particularly in lower-level fixtures like basement floor drains or first-floor toilets
- Sewage odors in the yard, near the foundation, or in the basement without a clear indoor plumbing source
- Slow drains throughout multiple fixtures simultaneously, rather than a single clogged drain
- Wet spots, soft ground, or unusually lush and fast-growing grass directly above the path of your sewer lateral
- Sinkholes or slight depressions forming in the yard along the line of the pipe
- Unexplained foundation cracks or settling that coincides with other sewer symptoms
- Rodent activity near clean-out locations, which can indicate gaps or breaches in the line
If your Denver home was built before 1970, there is a strong likelihood your sewer lateral is original clay tile or cast-iron pipe. These materials can last 50 to 100 years under good conditions, but age, root intrusion, ground movement, and the freeze-thaw cycles common on the Front Range accelerate their deterioration significantly.
A camera inspection run through the sewer lateral gives a precise diagnosis of the problem. It locates the failure, identifies the extent of damage, and determines whether a spot repair or full replacement is the appropriate approach. No guessing, and no unnecessary work.
The Apex Underground Trenchless Repair Process, From First Call to Final Inspection
Every trenchless sewer repair Apex Underground performs follows the same structured process, whether it’s a scheduled replacement or an emergency call at 2 a.m.
Step 1: Initial call and dispatch. Our team is available 24 hours a day, 7 days a week. For emergency sewer failures, same-day response is standard. For scheduled work, we’ll coordinate an assessment at a time that works for you.
Step 2: Camera inspection and diagnosis. A camera is run through the sewer lateral to locate the failure precisely, assess the pipe’s condition along its full length, and determine the right repair approach. You’ll see exactly what we see before any work is recommended.
Step 3: Method selection. Based on the camera findings, pipe condition, depth, material, and site layout, our team recommends HDD or pipebursting. We explain the recommendation and why it fits your specific situation.
Step 4: Permits and planning. Apex Underground manages the permitting process with the City of Denver and any relevant local municipality. Homeowners are not responsible for obtaining or managing permits. This is included in our turnkey service from initial assessment through project completion.
Step 5: Trenchless repair or replacement. Work begins with minimal surface disturbance. Most residential trenchless sewer repairs are completed within a single day.
Step 6: Final inspection and restoration. After the repair is complete, a post-repair camera inspection confirms the line is clear, properly seated, and flowing correctly. Any surface disturbance at the access points is restored before the crew leaves.
This start-to-finish, single-source approach means one team manages your project from the first call through the final sign-off. No handoffs, no subcontracted pieces, no gaps in accountability.
Trenchless Sewer Repair Cost in Denver and Financing Options
Trenchless sewer repair is a meaningful investment, and we won’t pretend otherwise. The technology and equipment required are more sophisticated than open-cut excavation, and that is reflected in the upfront cost. But here’s the full picture: open-cut excavation requires excavating, restoring, and often replacing landscaping, concrete, driveway sections, or hardscaping that can add several thousand dollars to the total project cost. When you factor in total cost rather than just repair cost alone, trenchless is frequently comparable to or less expensive than open-cut for established properties.
The more important consideration is timing. A failing sewer line does not stabilize on its own. A cracked or root-infiltrated lateral that costs a certain amount to address today will cost considerably more after a full collapse, a sewage backup into the home, or structural damage from prolonged soil saturation. Delaying the repair almost always increases the eventual cost.
Apex Underground offers financing through Hearth, making it possible to address a sewer line failure immediately without paying the full project cost upfront. Hearth provides flexible financing options that allow Denver homeowners to protect their property now and manage the expense over time rather than waiting on a repair that will only worsen.

Trenchless Sewer Repair Denver: Frequently Asked Questions
Our customers often ask questions about our services and repair methods. Here are answers to common inquiries:
Can you repair my sewer line without tearing up my yard or driveway?
How long does a trenchless sewer repair take in Denver?
Most residential trenchless sewer repairs are completed within a single day. The initial camera inspection to diagnose the problem typically takes one to two hours, and the repair itself using HDD or pipebursting follows the same day in most cases. Emergency repairs are prioritized for same-day or next-day service, and Apex Underground maintains a dedicated emergency crew available around the clock for active failures.
How do I know if I need a spot repair or a full sewer line replacement?
The extent of damage determines the method, and the only reliable way to know is a camera inspection run through the sewer lateral. Localized damage, such as a single cracked section or a minor root intrusion at one joint, may be addressed with a targeted spot repair. A line that is extensively deteriorated, root-infiltrated along its full length, or has shifted and separated from ground movement typically requires full replacement. The Apex Underground team will show you the camera footage and explain exactly what was found and what is recommended before any work begins.
