Sewer Line Replacement in Commerce City, CO

End Recurring Backups With a Line Built to Last

Building sewers in Commerce City must be installed no less than 12 inches below grade under the adopted 2021 International Plumbing Code, and many older homes here still drain through vitrified clay laid decades before that standard. Clay joints invite tree roots, then shift, then collapse. JAC's Plumbing replaces failing sewer lines across Commerce City, CO and nearby Thornton, Northglenn, and Denver, converting brittle clay and corroded cast iron to modern PVC. Root intrusion follows the same predictable path.


Camera footage and a locate come first, because the decision between spot repair and full replacement should be based on what the pipe actually looks like inside. We handle permits, coordinate inspection, restore the excavation, and stand behind the work with 23 years of underground plumbing across the north metro. Restoration and compaction are part of the quoted price, not an add on. Reach us through the contact page and we will show you the video before recommending anything.

Sewer Lines We Replace

  • Full Sewer Line Replacement

    Once a line has multiple bellies, offsets, or collapsed sections, spot fixes stop making sense. Replacing the complete run from the house connection to the city main gives you consistent slope and a pipe rated for decades of service.

  • Trenchless Pipe Bursting

    A bursting head fractures the old pipe outward while pulling new HDPE into the same corridor. Driveways, patios, and mature trees stay where they are, and the finished line often has a larger inside diameter than the original.

  • Cured-in-Place Pipe Lining

    Where the host pipe still holds its shape, a resin saturated liner cures into a jointless new wall inside it. Root intrusion ends at the joints because there are no longer any joints for roots to find. Flow capacity barely changes.

  • Clay and Cast Iron Conversion

    Vitrified clay cracks and cast iron scales until the effective diameter shrinks by half. Replacing either with solid wall PVC eliminates the root pathways and the rough interior that catches paper and grease month after month. Drain noise usually improves too.

  • Sewer Cleanout Installation

    Without an accessible cleanout, every future service call starts by pulling a toilet. Adding one at the right point on the line makes routine maintenance faster and cheaper for as long as you own the property. Future plumbers will thank you.

  • Excavation and Site Restoration

    Open cut work is sometimes unavoidable, especially near the city connection. We keep the trench tight, compact the backfill in lifts so the ground does not sink later, and put the surface back the way we found it.

Why Choose Us for Sewer Line Replacement

Camera Evidence Before Any Recommendation

You see the same footage we do, with the trouble spots marked and located. That transparency is why homeowners stop worrying about being upsold into a replacement when a targeted repair would have solved the problem. You keep a copy of the recording.

Methods Matched to Your Property

Bursting, lining, and open cut each fit different conditions, depths, and pipe materials. Picking the right one keeps cost and disruption proportional to the actual problem instead of defaulting to whatever is easiest for the crew. We explain the tradeoffs plainly.

Backups That Stop for Good

Repeated snaking treats the symptom while roots keep growing back through the same joint. A replaced line removes the pathway entirely, ending the annual routine of emergency calls and unusable bathrooms during family gatherings. That relief is the real deliverable here.

Permits and Inspections Managed

Sewer work is permitted and inspected, and unpermitted replacements create real problems during a future sale. We handle the filings and the inspection appointment so the finished project is documented properly from the start. You receive the signed inspection record afterward.

Compacted Backfill That Holds

Loose fill settles into a trench shaped depression across your yard within a year. Layered compaction takes longer on our end and saves you from regrading, resodding, or watching a driveway crack along the line we opened. Settling is a finishing failure.

One Team From Diagnosis to Cleanup

The people who scoped the line are the people who replace it and the people who restore the surface. Nothing gets lost in a handoff, and there is one number to call if anything needs attention afterward. Accountability stays in one place.

A Sewer Line You Can Finally Stop Thinking About

Living with a failing sewer means planning holidays around a line that might back up, and that quiet stress never quite goes away.

Reach out through our contact page and we will get a camera down the line before anyone talks about digging. Seeing the condition of your own pipe changes how the decision feels.

Frequently Asked Questions

  • How do I know if my sewer line needs replacing rather than cleaning?

    Repeated backups after cleaning, multiple slow drains at once, sewage odor in the yard, and camera footage showing collapsed or offset sections point to replacement. A single localized clog usually clears and stays clear for years. Footage removes most of the guesswork.

  • How long does sewer line replacement take?

    Trenchless bursting or lining commonly finishes in a single day. Open cut replacement typically runs two to four days depending on depth, length, driveway or sidewalk removal, and how quickly the required inspection can be scheduled. Restoration work can extend that.

  • What causes sewer lines to fail?

    Tree roots entering clay joints, ground shifting that creates low spots, corrosion in cast iron, grease accumulation, and simple age all contribute. JAC's Plumbing finds root damage most often in Commerce City, CO homes built before the 1980s.

  • Is trenchless sewer replacement always possible?

    No. Severely collapsed pipe, sharp bends, or lines running under structures can rule it out. A camera inspection and locate determine feasibility before anything is quoted, since a failed trenchless attempt costs more than starting with excavation. Feasibility is decided before quoting.

  • Will my homeowners insurance cover a sewer line replacement?

    Standard policies usually exclude gradual failure and normal wear, though some carriers sell a separate service line endorsement. Sudden damage from an outside cause is more often covered. Reviewing your specific policy language is worth the time. Endorsements are usually inexpensive.

  • How long does a new sewer line last?

    Modern PVC and HDPE lines are rated for 50 to 100 years when properly bedded and sloped. Avoiding flushable wipes, grease, and planting large trees over the run keeps that lifespan realistic rather than theoretical. Proper slope matters as much as material.

  • Do I need to be home during the replacement?

    Access to the interior cleanout or basement is helpful at the start and end, though most of the work happens outside. Water service continues, but drain use pauses while the line is disconnected during the changeover. We coordinate timing in advance.

  • Can roots be removed without replacing the pipe?

    Cutting and jetting clears roots temporarily, but they return through the same joint within a year or two. Our crews at JAC's Plumbing serve Commerce City, CO homeowners who have snaked annually for a decade before replacing. Lining the entry joint changes that.
