- Repair method is selected — spot repair, pipe bursting, CIPP lining or open trench
- Permits and utility locates are arranged by the contractor
- Repair is completed, re-inspected on camera and the surface restored
Scope boundary
What a standard visit covers — and what is billed on top
The single biggest source of quote disputes is the boundary between these two columns. Get it written down before work starts.
| Normally included | Commonly billed on top |
|---|---|
| Camera inspection and above-ground locating of the failed section | Permits, utility locates and right-of-way fees charged by the jurisdiction |
| Excavation or trenchless access at the identified defect point | Concrete, asphalt or paver cutting and reinstatement over the trench line |
| Replacing or lining the damaged run and reconnecting to sound pipe | Landscaping, irrigation and fence removal and replacement along the excavation route |

Before you sign
Questions to ask before authorising sewer line repair
- 01
Will a post-repair camera recording and locate report be supplied, since that documentation matters for insurance and future sale disclosures?
- 02
Where exactly does the camera place the defect in feet from the cleanout, and is it on private property or the utility's side?
- 03
Which method is proposed — spot repair, pipe bursting, cured-in-place lining or open trench — and why does this defect suit it?
- 04
Does the quote include utility locates, permits and traffic control if the excavation reaches the sidewalk or roadway?

Answers first
Sewer Line in Colorado — frequently asked
Who is responsible for the sewer line — me or the city?
In most jurisdictions the property owner owns the lateral from the building to the point of connection, which often extends under the sidewalk and into the street. The municipality owns the main. Where the boundary sits varies by city, so confirm with your local utility before authorising excavation.
Is trenchless sewer repair always better?
Not always. Trenchless methods avoid destroying driveways and landscaping and are usually faster, but they require the host pipe to be in a repairable condition and continuous. A fully collapsed or badly misaligned line, or one with a severe belly, generally still needs excavation.
Does homeowner's insurance cover sewer line replacement?
Standard policies typically exclude gradual failure and wear of an underground line, though some carriers sell a service-line endorsement. Sudden damage may be treated differently. Check your specific policy language before assuming coverage.
Are night and weekend calls handled differently in Colorado?
Requests route around the clock, but most contractors price after-hours work differently. Ask for the after-hours rate and a committed arrival window before agreeing to a dispatch.
What information speeds up a sewer line callback?
Three things: where the water or problem is showing, whether the supply is shut off, and the property type — slab, crawl space or basement. With those, a pro covering Colorado can triage the urgency and bring the right parts.
How should a sewer line quote be compared?
Line by line against scope: what is included, what is excluded, who pulls the permit, and whether haul-away and restoration are inside the number. The cost guides on this site list published third-party ranges so any quote can be sanity-checked.
Who handles the permit for sewer line in Colorado?
The licensed contractor pulls the permit — never the homeowner. If a contractor proposes skipping a required permit, treat that as the signal to stop and verify the licence.
What warranty applies to the work?
Whatever the contractor offers in writing — PlumberColorado is not a party to the agreement. Ask for labour and parts warranty terms in the quote, and keep the licence number with the paperwork.
