Henderson, CO Sewer Line Replacement Cost Per Foot 2026

Estimated Read Time: 12 minutes

Sticker shock from a sewer issue is real. Homeowners often ask, “What’s the sewer line replacement cost per foot?” In 2026, the answer depends on depth, access, and whether you choose trenchless or open-trench methods. Below, we break down Denver-specific ranges, the variables that move your price up or down, and how to save without risking a second dig.

Good news: Golden West offers same-day camera inspections and multiple repair options so you can compare costs with confidence.

Average Cost per Foot in 2026: Denver-Area Ranges

Per-foot pricing helps you forecast quickly, but every property has its own variables. Based on typical projects we see across Denver, Aurora, Lakewood, and nearby communities in 2026:

• Open-trench dig-and-replace: about $80 to $225 per linear foot for most residential depths and materials. Deep, hard-to-access runs can exceed that range.
• Trenchless pipe bursting: about $110 to $240 per foot, depending on access pits, depth, and surface restoration needs.
• Trenchless CIPP lining (cured-in-place): about $120 to $260 per foot, often chosen when the host pipe has continuous defects but can still serve as a conduit.

Keep in mind that per-foot rates rarely include every cost line item. Permits, traffic control, utility locating, cleanouts, and surface restoration can add to the total. The sections below explain what drives price and how to make a cost-efficient choice.

What Drives Sewer Line Cost Per Foot

Several field conditions push pricing up or down. Focus on these during your inspection and estimate review:

1. Depth and soil conditions
   • Deeper lines require more excavation, shoring, and hauling. In Denver’s Front Range clay and mixed fill, wet or collapsing soils can slow production.
   • Shallow runs under soft landscaping are faster and cheaper per foot.
2. Access and obstacles
   • Fences, mature trees, garages, or additions over the line raise costs. Removing and rebuilding hardscape takes time and materials.
   • Busy streets can require traffic control or after-hours work.
3. Method selection
   • Open-trench is straightforward for short, shallow, or isolated failures.
   • Trenchless methods reduce surface disruption and often cut restoration costs, which can make the total job cheaper even if the per-foot rate is higher.
4. Pipe material and diameter
   • Clay tile and Orangeburg in older Denver neighborhoods often need full replacement.
   • Larger diameters, transitions, and multiple tie-ins add labor and fittings.
5. Permits, inspections, and compliance
   • The City and County of Denver requires permits and inspections for replacements. Final approval typically demands a code-compliant installation and a passing test.
   • If your line connects to a district main or crosses public right-of-way, additional approvals may apply.
6. Restoration scope
   • Replacing concrete, flagstone, or asphalt can equal or exceed digging costs. Trenchless can sharply reduce this line item.

Trenchless vs. Open-Trench: When Each Makes Sense

Both approaches are reliable when designed and installed correctly. The right choice depends on the condition of your line and your property priorities.

• Choose open-trench when:
  • The failure is localized, shallow, or near the foundation.
  • You plan concurrent landscaping or slab work and do not mind restoration.
• Choose trenchless when:
  • You want minimal disruption to driveways, mature landscaping, or finished spaces.
  • The line is deep, long, or runs under sidewalks and streets.

Trenchless advantages homeowners value most:

• Reduced property damage and restoration
• Faster turnaround and less disruption
• Competitive total project cost
• Long-lasting results when properly designed and installed

Real-World Price Scenarios

Use these examples to see how the variables stack up. Your project may differ, but the math offers a helpful benchmark.

1. Small, shallow spot repair (open-trench)
   • Scope: 8 feet outside the foundation, 4 feet deep, clay soil, lawn only
   • Per-foot: $120
   • Add-ons: permit, basic restoration
   • Rough total: $1,500 to $2,200
2. Full replacement, open-trench, moderate depth
   • Scope: 45 feet to the city tap, 7 feet deep
   • Per-foot: $150
   • Add-ons: permit, new cleanout, concrete panel replacement
   • Rough total: $8,000 to $10,500
3. Trenchless pipe bursting under driveway and sidewalk
   • Scope: 60 feet, two access pits, 8 feet deep at tap
   • Per-foot: $170
   • Add-ons: permit, camera verification, pit restoration
   • Rough total: $11,000 to $13,500
4. CIPP lining to address root intrusion and cracking
   • Scope: 55 feet from cleanout to main, structurally suitable host pipe
   • Per-foot: $185
   • Add-ons: permit, reinstating branch connections if present
   • Rough total: $10,000 to $12,500

These ranges reflect the Denver metro in 2026 for typical residential jobs we see. Complex access, extreme depth, or extensive concrete and asphalt can increase totals.

How Camera Inspections Lower Your Cost

A high-quality sewer camera inspection lets you see the problem before you dig. Our licensed technicians insert a flexible camera through an access point and capture live video of the pipe interior. With the exact location and nature of the defect, we can recommend the most cost-effective fix:

• Verify whether a spot repair will hold or a full replacement is smarter
• Choose trenchless where it saves on restoration
• Confirm footage and depth to prevent scope creep

Camera inspections help you avoid paying per foot for pipe that does not need replacement. Many homeowners recoup the inspection fee through a more targeted repair.

Permits, Codes, and Inspections in the Denver Area

Compliance is not optional and should be included in your estimate. Key checkpoints:

• Permit application and approved plans where required
• Utility locating before any dig by calling 811
• Inspection after replacement or lining, with a passing test and video where applicable
• Proper slope and bedding, and code-compliant materials and fittings

Golden West has served Denver since 2002 and maintains current trade licenses. We coordinate permits, schedule inspections, and provide post-repair documentation so you have a clean record of the work.

Trenchless Methods Explained in Plain Language

Trenchless pipe bursting

• A new HDPE pipe is pulled through the old line while a bursting head fractures the host pipe outward. Ideal for collapsed or badly broken lines where a new, continuous pipe is the best solution.

CIPP lining

• A resin-saturated liner is inverted or pulled through the pipe, then cured to form a new pipe within the old one. Effective when the host pipe still has enough integrity to serve as a form.

Both methods use small access pits, reduce surface demolition, and often deliver faster timelines than open-trench.

How to Read and Compare Sewer Estimates

Not all bids are apples to apples. Ask these questions so you can align price with value and risk:

1. What is the exact linear footage being replaced or lined? Is the footage clearly marked from cleanout to tap or structure to property line?
2. What method is being used and why was it chosen over alternatives?
3. What is included in restoration and what is excluded?
4. Are permits, inspections, traffic control, and haul-off included?
5. What warranty applies to materials and labor, and what is the claim process?
6. Will there be a final camera verification and a copy of the recording?

A transparent estimate should itemize these elements, not just list a single per-foot number.

Ways to Save Without Cutting Corners

• Choose trenchless when restoration would be expensive
• Time repairs before peak ground saturation or freezing conditions
• Use financing to proceed with the right fix now and avoid compounding damage
• Become a VIP member if available to reduce diagnostic and follow-up fees
• Approve a cleanout installation if you do not have one to lower maintenance costs

Preventive maintenance matters too. Routine camera inspections and timely root management can extend pipe life and reduce future replacement footage.

Signs You May Need Replacement Now

• Recurring sewage backups despite recent clearing
• Sewage odors or saturated areas along the line path
• Foundation or slab movement tied to leaks
• Known clay tile or Orangeburg pipes in older Denver homes

A camera inspection can confirm whether you need a spot fix, a sectional repair, or a full replacement.
