Sewer Line Replacement in North half of Denver metro area, CO

Sewer line replacement is a major home service that protects your property from recurring backups, contamination, and foundation damage. In the North half of the Denver metro area, CO, aging pipes, expansive soils, and seasonal freeze-thaw cycles increase the risk of pipe failure. This page explains how full sewer line replacement works, the diagnostic steps we use, the difference between traditional trench and trenchless options, permitting and restoration expectations, timeline and cost drivers, financing options, and what you should expect before, during, and after work.

Why sewer line replacement is often necessary in North half of Denver metro area homes

• Many older homes in northern Denver suburbs were built with clay, cast iron, or vitrified clay laterals that degrade over decades.
• Expansive clay soils and freeze-thaw movement common to the area cause joint separation, pipe bellies, and root intrusion.
• Frequent backups, multiple cleanout visits, strong sewer odors, or sewage pooling in the yard usually indicate systemic pipe failure rather than a single clog.
• Replacing a failing lateral protects indoor plumbing, prevents costly foundation or landscaping damage, and brings lines up to modern material and code standards.

Common sewer line problems we diagnose

• Root intrusion at joints or offsets
• Collapsed or crushed pipe sections
• Longitudinal cracks and multiple small fractures
• Bellies (sagging runs that trap solids)
• Severe corrosion in cast iron or cast lead-welded joints
• Misaligned joints from ground settlement
• Frequent backups despite repeated snaking or hydrojetting

Diagnostic process: camera inspection and soil/line assessment

• Video camera inspection: A full-color sewer camera run from the cleanout to the main reveals the exact failure type, location, distance from the cleanout, and root/grease buildup. This inspection is the foundation for an accurate scope and estimate.
• Locating and mapping: We locate the lateral path, depth, and any conflicts with utilities. Accurate mapping reduces surprises during excavation.
• Soil and line condition assessment: Technicians evaluate soil type, groundwater level, and surrounding structures. Expansive soils or high groundwater may change the recommended replacement method.
• Hydrojetting (if needed): For lines that are still salvageable or to prepare for lining, high-pressure cleaning removes roots and debris so the camera can reveal true pipe condition.

Replacement options: trench versus trenchless

• Traditional trench replacement
• Excavation along the full lateral to remove and replace the failed pipe.
• Best when the pipe is severely collapsed, has multiple offsets, or when depth and alignment require full access.
• Allows installation of a new bedding, proper slope, and use of larger-diameter pipe where needed.
• Restoration includes backfill, compaction, and surface repairs to landscaping or hardscapes.
• Trenchless options
• Cured-in-place pipe (CIPP) lining: A resin-saturated tube is inverted or pulled into the existing pipe and cured, forming a seamless new pipe inside the old one. Ideal for continuous cracks, small collapses, or lines with intact host pipe.
• Pipe bursting: The old pipe is fractured outward while a new pipe is pulled into place. This can replace clay or cast iron with more durable HDPE or PVC without digging the whole trench.
• Slip lining and directional drilling: Used in specific access-limited situations or under driveways and foundations to minimize surface disruption.
• Trenchless methods reduce surface restoration, shorten downtime, and are often preferred when preserving landscaping or driveways is a priority.

Materials used and code considerations

• Common new materials include SDR-35 PVC, schedule 40 PVC, and HDPE for trenchless installations. These materials resist corrosion and root intrusion and typically provide a service life of many decades.
• Lining materials use industry-grade epoxy resins formulated to meet local sewer standards.
• Replacement will meet local permitting and code requirements, including proper slope, cleanout placement, and connection details at the municipal main.

Permitting, inspections, and restoration

• Most replacements require local permits and an inspection process. Permit timelines vary by jurisdiction in the North half of Denver metro area and can affect project scheduling.
• Restoration scope depends on the chosen method: full trenching will require soil compaction, reseeding or sod, and repair or replacement of concrete driveways and sidewalks. Trenchless methods typically need only small access pits and reduced landscaping repair.
• Proper compaction and staged restoration prevents future settlement issues. Concrete and asphalt repairs follow local compaction and cure standards before normal traffic resumes.

Typical project timeline

• Diagnostic and estimate: 1 to 3 days after the initial appointment.
• Permitting and scheduling: 3 days to 2 weeks depending on local permit turnaround.
• Work duration:
• Trench replacement: a few days to a full week for typical single-lateral jobs; larger or complex excavations may take longer.
• Trenchless replacement: often completed in 1 to 3 days for a single lateral.
• Final inspections and restoration: a few days to several weeks for landscaping and concrete to be fully restored and cured.

Cost factors that influence estimates

• Total linear feet of sewer to replace
• Accessibility and depth of the lateral
• Presence of concrete driveways, sidewalks, or landscaping requiring major restoration
• Soil conditions and groundwater level
• Need for additional repairs (cleanouts, manholes, or connection work at main)
• Method selected: trenchless solutions can reduce surface restoration costs but may have different material costs
• Required permits and inspection fees

Financing options

• For many homeowners, sewer replacement is an unplanned expense. Typical financing solutions can include payment plans, home improvement loans, or financing through third-party lenders. Financing availability, terms, and approval depend on the homeowner’s situation and local providers. Discussing financing early in the planning phase helps align the project scope and timeline with budget expectations.

What to expect before, during, and after work

• Before work: clear the work area of vehicles, toys, and garden items; mark sprinkler heads and remove fragile plants; locate any private lines or known utilities. We will provide scheduling and site-preparation details.
• During work: expect excavation equipment, temporary noise, and crews on site. For full replacements, a temporary sewer bypass may be installed so the home remains habitable. Safety barriers and daily cleanup are standard.
• After work: allow time for compaction and curing of repaired surfaces. Avoid parking on newly repaired driveways until concrete/asphalt meets strength requirements. A final camera inspection is common to confirm a clean, properly flowing line. You should receive documentation of the work completed, materials used, and any applicable warranties.

Long-term benefits and maintenance

• Replacing a failing lateral restores reliable sewer service, reduces health risks, and protects landscaping and foundations. Modern pipe materials and proper installation significantly reduce the likelihood of future failures.
• Routine maintenance—periodic camera inspections and professional hydrojetting when recommended—extends service life and helps identify problems early.
• In this region, addressing sewer issues proactively is especially important because freeze-thaw cycles and expansive soils can accelerate deterioration.
