When Replacement Is Needed
Signs You Need Sewer Line Replacement
These signs indicate the pipe has failed structurally — not just accumulated a blockage. Cleaning or spot repair won't provide a lasting solution:
Frequent sewer backups
If backups keep happening even after professional cleaning or repair, the pipe structure itself is failing — cleaning is no longer a solution.
Severe pipe damage on camera
A sewer camera revealing collapsed pipes, crushed sections, major cracks spanning multiple feet, or severe corrosion throughout means repair isn't viable.
Multiple drain failures at once
When every drain in the home fails simultaneously and cleaning doesn't hold, the main sewer line has likely failed structurally.
Soggy or sunken yard
A leaking sewer line saturates and erodes the soil above it — creating wet patches, depressions, or sinkholes above the pipe path.
Persistent sewer odors
Ongoing foul smells that return after cleaning indicate a broken pipe releasing gases that were meant to stay contained underground.
Old aging infrastructure
Clay, cast iron, and Orangeburg pipes in homes built before 1970 are at or beyond their design lifespan and typically warrant proactive replacement.
Your Options
Sewer Line Replacement Options
We select the replacement method after camera inspection confirms what the pipe actually needs — not based on what's most profitable for us:
Most Popular
Pipe Bursting
A hydraulic bursting head is pulled through the old pipe, fracturing it outward into the surrounding soil while simultaneously pulling a new HDPE pipe into place behind it. Requires only small access pits at entry and exit — no full trench.
- Full pipe replacement without a full trench
- Can increase pipe diameter in same pass
- Minimal disruption to landscaping and hardscape
- Suitable for most soil conditions and pipe materials
Pipe Lining (CIPP)
A resin-saturated felt liner is inserted and inflated inside the existing pipe, then cured to form a rigid new pipe within the old one. Effective when the pipe structure is still mostly intact but has cracks, leaks, or root entry points throughout.
- No excavation required
- New smooth interior surface
- Seals all existing cracks and root entry points
- 25–50 year lifespan for cured liner
Partial Sewer Replacement
When damage is concentrated in a specific section — a collapsed elbow, a severely offset joint, or a pipe bellied beyond re-grading — we excavate and replace only the damaged section, reducing cost and disruption compared to full-line replacement.
- Most cost-effective for isolated severe damage
- Smaller excavation footprint
- Combined with lining where appropriate
- Fast completion — often one day
Full Excavation Replacement
When the entire sewer line has failed — through widespread collapse, end-of-life Orangeburg, or damage along its full length — open-cut excavation and complete pipe replacement is the definitive solution. We install modern Schedule 40 PVC at proper slope and depth.
- New system for the entire run
- Correct slope and depth guaranteed
- Modern PVC or HDPE material
- Final camera inspection confirms completion
No-Dig Advantage
Trenchless Sewer Replacement Benefits
Trenchless methods are often preferred when applicable because they preserve your property while still delivering a full replacement result. When your sewer runs under a driveway, mature landscaping, or finished hardscape, trenchless protection of that investment is significant.
How We Work
Our Sewer Line Replacement Process
Sewer Camera Inspection
We run high-definition cameras through the entire line to document the damage location, type, and severity — producing footage you can review with us. This determines whether repair or replacement is appropriate and which method is feasible.
Diagnosis & Recommendation
We explain damage severity clearly, present repair vs. replacement options with honest cost breakdowns, and recommend the best long-term solution. We never push replacement when repair is genuinely the right answer.
Permit & Planning
Where required by your municipality, we pull the necessary permit and handle city compliance. In many Colorado jurisdictions, sewer line replacement requires a permit and inspection — we handle this so you don't have to.
Replacement Work
We execute the agreed method — trenchless bursting or lining with minimal access pits, or open-cut excavation and new pipe installation — with proper slope verification at every stage.
Final Testing & Inspection
After replacement, we run water through the full system to confirm flow, check for leaks at all connections, verify proper slope, and run the camera one final time. Before-and-after footage is provided for your records.
Replacement vs. Repair
When Does Replacement Beat Repair?
Replacement is often more cost-effective long-term when damage is extensive. Here's how the two approaches compare:

Why It Happens
Why Sewer Lines Need Replacement in Colorado
Colorado's specific conditions — expansive clay soils, freeze-thaw cycles, mature urban tree canopy, and a large stock of pre-1970 homes with original sewer infrastructure — create predictable failure patterns that our technicians know well.
Tree Root Intrusion
When roots have infiltrated a pipe so extensively that structural integrity is compromised — not just blocking flow but actually breaking the pipe apart — replacement is the only lasting fix.
Aging Pipe Materials
Orangeburg (tar-paper composite), clay tile, and cast iron all have finite lifespans. Orangeburg begins failing at 30–50 years; clay tile cracks and offsets; cast iron corrodes through. Once material failure is system-wide, replacement is more cost-effective than repeated patching.
Ground Movement
Colorado's expansive clay soils shift seasonally. Years of freeze-thaw cycling can crack, offset, or entirely separate pipe joints along a run — producing multiple failure points that exceed what spot repair can address.
Corrosion
Cast iron pipes corrode from the inside as well as outside. When the pipe wall is thinned to the point of collapse risk, replacement with modern PVC or HDPE is the only safe long-term option.
Improper Original Installation
Poor slope means water pools rather than flows, producing chronic debris accumulation and bacterial growth. Correcting slope requires replacing the line at proper grade.

Frequently Asked Questions
How do I know if I need sewer line replacement vs. repair?
The decision is based on what a camera inspection reveals. Repair is appropriate when damage is isolated — a single cracked section, one root entry point, or a limited area of pipe lining candidate. Replacement is recommended when the pipe is collapsed, has multiple simultaneous failure points, is made of end-of-life material (Orangeburg, severely corroded cast iron), or when repair costs approach replacement costs. We show you the camera footage and walk you through both options with honest pricing — the decision is yours with full information.
Can sewer lines be replaced without digging up my yard?
Yes, in many cases. Pipe bursting and pipe lining (CIPP) are trenchless methods that require only small access pits at each end rather than excavating the full length of the pipe. Whether trenchless replacement is appropriate depends on the pipe condition, soil type, pipe material, and access constraints. A camera inspection determines feasibility. When trenchless is possible, we almost always recommend it — it's faster, less disruptive to your property, and the end result is a new or rehabilitated pipe.
How long does sewer line replacement take?
Trenchless pipe bursting or lining for an average residential sewer line typically takes 1–2 days. Partial replacement of a specific damaged section usually takes one day. Full open-cut excavation and replacement of an average residential line (typically 50–150 feet) takes 2–4 days depending on depth, soil conditions, and restoration requirements. We'll give you a clear timeline before starting.
How long do new sewer lines last?
Modern Schedule 40 PVC pipe is rated for 100+ years in normal soil conditions. HDPE pipe used in pipe bursting is similarly long-lived. CIPP (cured-in-place pipe lining) has a manufacturer-rated lifespan of 50 years or more. All of these far exceed the materials they replace — Orangeburg (30–50 years), clay tile (50–60 years), and cast iron (75 years, but with active internal corrosion).
Will trenchless sewer replacement damage my yard?
Trenchless methods require access pits typically 3–4 feet wide at entry and exit points — not a full trench. Your lawn, landscaping, driveway, or patio over the pipe path is largely preserved. Some surface restoration is needed at the access pits themselves, but the disruption is significantly less than open-cut excavation. If the line runs under a driveway or finished landscaping, trenchless is often the primary reason we choose it.
Do you offer emergency sewer line replacement?
Yes. A collapsed sewer line or severe backup creating an active health hazard is treated as an emergency. Our team is available 24/7 — we respond with camera inspection to confirm the scope, then mobilize replacement as quickly as possible. For true emergencies, we prioritize getting your system operational and can often begin replacement the same day as diagnosis.
