- Take photos of visible symptoms if it is safe to do so.

Sewer Line Service Built Around Diagnosis, Not Guessing
Sewer problems often look similar on the surface, but the actual cause can be very different. A recurring backup could come from roots, a sagging line, a cracked section, grease buildup, old pipe deterioration, or a larger structural failure.
That is why our first job is to understand what is really happening underground. Once we inspect the line and identify the likely cause, we can recommend the most practical path forward - whether that means cleaning, targeted repair, trenchless replacement, pipe lining, or excavation.
Sewer Services We Evaluate and Perform
Sewer Line Repair
Targeted sewer line repair for damaged, leaking, cracked, offset, or failing pipe sections.
Trenchless Sewer Repair and Replacement
Less invasive repair and replacement options when the line condition, access, and project setup make trenchless methods the right fit.
Sewer Line Replacement and Installation
Full replacement or new line installation when the line is too damaged, too old, or too compromised for a smaller repair.
Sewer Scope and Video Inspection
Camera-based inspection to identify the actual condition of the line and guide the next decision with more confidence.
Sewer Locating and Troubleshooting
Line locating and problem diagnosis for unclear underground issues, recurring symptoms, and hard-to-find failure points.
Sewer Cleaning and Hydro Jetting
Cleaning services to remove buildup, debris, roots, and blockages while improving line function and helping prevent repeat backups.
Sewer Cleanouts
Cleanout-related service when access, maintenance, inspection, or repair requires a proper cleanout approach.
Sewer Leak Detection
Leak-focused sewer diagnosis when line damage or underground seepage is suspected.
Sewer Pipe Lining
Pipe lining options for qualifying line conditions where internal rehabilitation makes more sense than full excavation.
Sewer Excavation
Excavation-based sewer work for lines that need full access, deeper correction, or conditions trenchless methods cannot solve well.

Why Homeowners and Property Managers Choose a Specialist for Sewer Line Work
Focused Sewer Expertise
General plumbing companies often treat sewer work as one more service. This page should position Denver Sewer & Water as a team that actually focuses on underground line problems and the decisions that come with them.
Education Before Pressure
Customers want to understand what is wrong, what the options are, and why one repair path makes more sense than another. That clarity builds trust and improves conversion quality.
Trenchless When It Fits
Trenchless repair and replacement are powerful options, especially when reducing disruption matters, but they are not the right answer for every line condition. We explain when trenchless makes sense and when excavation is the better route.
Inspection and locating matter
High-intent visitors want to know that the company can diagnose accurately, not just sell a repair. That means camera inspection, locating, and real problem assessment should be central to the page.
Multiple Repair Paths Under One Roof
This page should make it clear that Denver Sewer & Water can route a sewer problem into cleaning, repair, trenchless work, lining, replacement, or excavation based on what the line actually needs.
Common Signs of a Sewer Line Problem
- Repeated backups in lower-level drains, tubs, or floor drains.
- Slow drainage in multiple fixtures at the same time.
- Sewage odors inside or outside the property.
- Recurring clogs that keep coming back.
- Wet or soggy spots in the yard near the likely line path.
- Gurgling toilets or drains when water is used elsewhere.
- Old sewer lines with known material or age concerns.
- Tree root intrusion or suspected underground breakage.
If one or more of these issues sounds familiar, inspection is usually the safest next step.
Trenchless if Possible. Excavation if Necessary.
One of the biggest questions customers have is whether the sewer line can be fixed without tearing up the yard, driveway, or landscaping. Sometimes it can. Sometimes it should not.
The right answer depends on the line material, location of the damage, how severe the failure is, access conditions, and what kind of long-term result the project needs.
Trenchless May Be a Fit When
- The line condition supports a less invasive repair or replacement method.
- Property disruption matters and access can be created efficiently.
- The goal is to restore line performance without opening a long trench.
Excavation May Be the Better Path When
- The line is collapsed, badly offset, deeply compromised, or affected by site conditions that require full exposure.
- Code requirements, depth, access, or surrounding infrastructure make open repair the smarter choice.
We inspect first, then explain the options clearly so the customer understands whether repair, lining, trenchless replacement, or excavation makes the most sense.

Do You Need Sewer Line Repair or Full Replacement?
Repair may be the right move when
- The issue is limited to a smaller section of pipe.
- The rest of the line is still in serviceable condition.
- A targeted fix solves the actual cause of the problem.
Replacement may be the better move when
- The line is broadly deteriorated, repeatedly failing, or too compromised for a durable repair.
- There are multiple damaged sections or long-term reliability concerns.
- The material, age, or line condition makes replacement the smarter long-range decision.

Frequently Asked Questions
Do I Need a Sewer Inspection Before Repair?
In many cases, yes. Inspection helps identify the actual line condition and supports a smarter recommendation instead of guessing.
Can Trenchless Sewer Repair Fix Every Sewer Problem?
No. Trenchless methods are excellent in the right situations, but some sewer lines still need excavation or a different repair path depending on the damage and access conditions.
What Causes Sewer Line Problems in Denver?
Common causes include roots, buildup, aging pipe materials, cracks, offsets, sagging sections, blockages, and broader structural deterioration.
How Do I Know if I Need Repair or Full Replacement?
That depends on the condition of the line, how much of it is affected, and whether a targeted fix will create a reliable long-term result.
Do You Only Work on Residential Sewer Lines?
No. Denver Sewer & Water also works with commercial properties and other property stakeholders who need sewer line diagnosis, repair, replacement, or maintenance-related service.
Do You Also Clean Sewer Lines?
Yes. Cleaning, hydro jetting, and maintenance-related services can be part of the right solution when buildup or blockage is the main issue.
