2026 Sewer Line Replacement Cost Per Foot: The Short Answer

Most Denver‑area sewer replacements in 2026 land in these per‑foot ranges:

• Traditional excavation: $110 to $250 per foot
• Trenchless pipe bursting: $150 to $300 per foot
• Trenchless CIPP lining: $180 to $350 per foot

Why the spread? Depth, access, surface restoration, and pipe size drive the number more than material alone. A typical 40 to 70‑foot residential run often totals $6,500 to $18,000, but well‑planned trenchless projects with good access can come in lower. Complex digs under driveways or mature landscaping can run higher.

"Justin A. was on time, highly professional and fixed my drain line clog in less than an hour for a reasonable price that was quoted before he began. We will be using them as our go to plumbing service in the future" –Justin A., Denver

What Drives Sewer Cost Per Foot in the Front Range

Four factors swing price the most in Denver, Aurora, Thornton, and nearby cities:

1. Depth and soil conditions
   • Shallow lines cost less. Deep lines need shoring, extra crew, and time.
   • Expansive Front Range clay and freeze‑thaw cycles can slow excavation and backfill.
2. Access and surface restoration
   • Under lawns is cheaper than cutting and replacing concrete, pavers, or asphalt.
   • Fences, sheds, or tight side yards increase labor and equipment needs.
3. Method: trenchless vs. open‑cut
   • Trenchless minimizes digging and can bypass obstacles. It can reduce restoration costs.
   • Open‑cut can be efficient on very shallow or short runs with easy access.
4. Pipe diameter and fittings
   • Most homes use 4‑inch or 6‑inch. Larger diameter and multiple tie‑ins raise material and labor costs.

Trenchless vs. Traditional: Which Lowers Your Total?

• Trenchless pipe bursting
  • Replaces the old pipe by pulling new HDPE through while breaking the old line.
  • Ideal when driveways, trees, or patios would make open‑cut expensive.
  • Typical 2026 range: $150 to $300 per foot.
• Trenchless CIPP lining
  • Creates a new resin‑cured pipe inside the old line without full replacement.
  • Great for minor offsets, small cracks, and root‑damaged clay when the host pipe has shape.
  • Typical 2026 range: $180 to $350 per foot.
• Traditional excavation
  • Best for collapsed sections, major bellies, or when the pipe has lost shape.
  • Restoration costs matter: lawns are cheap, concrete and hardscape are not.
  • Typical 2026 range: $110 to $250 per foot.

Local tip: Older Denver neighborhoods often have clay or cast‑iron laterals. Trenchless can preserve mature trees and historic hardscape that would be costly to rebuild.

Permits, Inspections, and Code Items That Affect Price

• Sewer permits and inspections are required in the Denver metro. Plan for city fees and scheduling windows.
• Colorado law requires you to call 811 before any digging. State statute (CRS 9‑1.5) mandates utility locates at least two business days before excavation.
• Proper slope is critical. Modern code requires gravity lines to maintain consistent fall to prevent standing water and backups.
• Cleanouts may be added for future maintenance, which slightly increases current cost but lowers lifetime ownership cost.

Hard facts you can count on:

• Colorado 811 notification is required by law prior to excavation. Fines can apply for violations.
• Denver’s frost depth is about 36 inches. Sewer laterals are commonly deeper than the frost line, which influences labor, shoring, and safety planning.

What a Professional Estimate Should Include

A camera‑verified estimate prevents guesswork and surprise adders. Expect:

1. CCTV inspection with recording and depth/location marking.
2. Written scope showing method (bursting, lining, or open‑cut) and exact footage.
3. Surface restoration plan for lawns, beds, concrete, or asphalt.
4. Permit and inspection schedule, including traffic or sidewalk considerations if needed.
5. Warranty terms on materials and workmanship.
6. Financing options and payment schedule.

"I had a clog in my kitchen drain at a spot in the outgoing drainage system that leads into the main sewer line... Connor identified the outgoing drain blockage and the probable area in the pipe involved and used the appropriate equipment to correct the problem quickly and efficiently. Great service!" –Connor, Denver

Sample Scenarios and Ballpark Pricing

These examples reflect common Denver‑area conditions. Your price will be verified by camera and site visit.

1. Short, shallow lawn run (35 feet, 4‑inch, minimal roots)
   • Open‑cut: $110 to $160 per foot
   • Total: ~$3,850 to $5,600
   • Why lower: Easy access and low restoration.
2. Under driveway with mature trees (55 feet, 6‑inch)
   • Pipe bursting: $190 to $280 per foot
   • Total: ~$10,400 to $15,400
   • Why mid‑to‑high: Access pits plus concrete considerations. Trenchless avoids full slab replacement.
3. Host pipe holds shape but has offsets and roots (60 feet)
   • CIPP lining: $200 to $320 per foot
   • Total: ~$12,000 to $19,200
   • Why: Resin, curing, reinstating connections, and pre‑cleaning.

How to Lower Your Cost Without Cutting Corners

• Choose trenchless when surfaces are expensive to replace.
• Approve a cleanout now to reduce future service costs.
• Bundle necessary drain cleaning and pre‑lining prep during the same visit.
• Ask for a combined camera report plus estimate to avoid duplicate diagnostics.
• Use financing to spread payments while protecting your property value.

What To Expect From Our Process

• Step 1: Camera inspection
  • We run a CCTV camera to pinpoint cracks, bellies, roots, or collapses and log depth by foot.
• Step 2: Clear and prep
  • Hydro‑jetting removes heavy roots and scale so we can evaluate the true condition.
• Step 3: Options and fixed price
  • You see a side‑by‑side of open‑cut, bursting, or lining with per‑foot pricing, restoration notes, and timeline.
• Step 4: Permit and utility locates
  • We manage permits and schedule Colorado 811. You do not have to coordinate utilities.
• Step 5: Install and restore
  • We replace or rehabilitate to code using durable, high‑quality materials that hold up long‑term, then restore the area.

Signs Your Sewer Needs Replacement, Not Just Cleaning

• Recurring sewage smells or gurgling after recent cleaning
• Soggy or sunken yard sections along the line path
• Multiple fixtures backing up together
• Camera shows bellies, major offsets, or collapsed segments

If a section is failing but not the whole line, a point repair may be appropriate. We perform targeted excavation or spot lining to minimize disruption and cost.

Trenchless Technology Benefits in Denver Neighborhoods

• Minimal disruption to landscaping, driveways, and sidewalks
• Faster completion than full excavation in most cases
• Cost‑effective when surface restoration would be expensive
• Long‑lasting materials designed for gravity sewer service

Our crews use pipe bursting, point repair liners, and CIPP for the right problem at the right price. You get the new sewer line you need without the mess you do not.

Material and Warranty Considerations

• Pipe materials are selected for local soil and groundwater conditions.
• Joints, transitions, and connections to the city main are built to code and pressure‑tested or inspected as required.
• Warranties vary by method and site conditions. We provide terms in writing so you know your coverage.

How Denver Compares to Nearby Cities

Per‑foot pricing is broadly similar across Aurora, Thornton, Arvada, Boulder, Westminster, Centennial, Lafayette, Longmont, and Highlands Ranch. Differences usually come from:

• City permit and inspection fee structures
• Access challenges on tight urban lots vs. newer subdivisions
• Restoration standards for sidewalks or ROW work

Maintenance After Replacement

Protect your investment with simple habits and scheduled care:

• Do not flush wipes, feminine products, or grease.
• Use root maintenance only as recommended by your plumber.
• Schedule routine sewer cleaning annually if you have heavy trees or a history of roots.
• Consider our Home Care Club for reminders, priority service, and member pricing on future work.

Frequently Asked Questions

How many feet of sewer line do most homes have?

Most Denver‑area homes have 40 to 70 feet from the house to the city tap, but lots vary. Corner lots, long setbacks, and rear alley taps can extend runs to 90 feet or more. A camera inspection with a locator wheel gives the true footage used to price your project.

Is trenchless always cheaper than digging?

Not always. Trenchless often wins when you would otherwise destroy and rebuild patios, trees, or long driveways. For short, shallow lawn runs, open‑cut can be less. A side‑by‑side estimate that includes restoration costs reveals the lowest total for your property.

Can you line a pipe with major bellies or collapses?

CIPP lining needs the host pipe to maintain shape. Severe bellies or collapses often require pipe bursting or open‑cut replacement. We verify with CCTV and depth readings, then recommend the safest method that meets code and protects flow.

How long does a sewer replacement take?

Simple open‑cut lawn replacements can finish in one to two days. Trenchless projects with access pits are often done in a day. Add time for permits, utility locates, inspections, and any concrete curing or surface restoration required by your city.

Do you handle permits and Colorado 811 locates?

Yes. We pull required permits, schedule inspections, and request Colorado 811 utility locates as state law requires. You will receive scheduling updates and a single point of contact so you are never guessing about next steps.

Final Takeaway

In 2026, sewer line replacement cost per foot in the Denver area typically ranges from $110 to $350 depending on depth, access, and method.
