Nationally, sewer line repairs run from a few hundred dollars for a cleared blockage to $3,000–$25,000+ for full excavation and replacement, with trenchless repairs typically landing in between. The spread is that wide because "sewer repair" covers five different jobs. The only way to know which job your Denver-area line needs — and what it actually costs — is a camera inspection.
What decides the price?
Five things, in rough order of impact: what is actually wrong (a clog is not a collapse), the repair method it calls for, how long the damaged run is, how deep the pipe sits, and what sits above it — lawn is cheap to restore, a stamped-concrete driveway is not.
| Factor | Why it moves the price |
|---|---|
| Problem type | Blockage vs. crack vs. belly vs. collapse — different jobs entirely |
| Repair method | Jetting, then lining/milling, then spot dig, then full replacement — in rising order |
| Length affected | Trenchless and excavation both price largely per foot |
| Depth | Deeper lines mean more digging, shoring, and time |
| Surface above | Restoring turf is cheap; concrete, mature trees, and streets are not |
What does each repair method cost?
These are national orientation ranges from published home-services cost data (Angi and similar cost guides) — not a quote. Front Range jobs vary with soil, depth, and access, and we quote only after a camera pass.
| Method | What it fixes | Typical national range |
|---|---|---|
| Hydro jetting | Grease, roots, buildup — line intact | $300–$1,000+ |
| Camera inspection | Diagnosis — always the first step | $100–$500 |
| Milling / descaling | Hardened scale, failed liners | Varies with length and condition |
| Epoxy brush coating | Cracks, corrosion — pipe still sound | Priced per foot; typically thousands, below replacement |
| Excavation and replacement | Collapsed or unrepairable line | $3,000–$25,000+ by length, depth, surface |

Why do Denver-area lines fail in the first place?
Two local culprits show up on our camera constantly: mature-tree root intrusion in Denver's older neighborhoods, where decades-old clay pipe joints practically invite roots in, and joint movement from the Front Range's expansive soils, which swell and shrink with moisture and shear pipes out of alignment. Older homes may also have Orangeburg (bituminized-fiber) pipe, which deforms with age and always ends in replacement.
How do you avoid overpaying?
- Never accept a repair quote made without camera footage. If they did not look, they are guessing — usually in their favor.
- Ask whether a cleaning could solve it first. Plenty of "you need a new line" calls end with a jetting at a tenth of the price.
- Get the trenchless option priced. If a company only sells digging, every problem looks like an excavation.
- Count restoration. An excavation quote that ignores your driveway, sprinklers, and landscaping is not the real number.
The most expensive words in this trade are "let's just dig it up." After 25+ years and a lot of camera footage, our honest experience is that most of the lines we're called to look at don't need replacement — they need the right cleaning or a lining. That's why every quote we give starts with the camera and ends with you watching your own pipe on the monitor. When a line truly is done, we'll show you exactly where and why — and dig one hole, in the right place.
What should you do next?
If your drains are showing the warning signs, book a camera inspection before anything else. It is the cheapest step in the whole process and it converts every number on this page from "national range" to "your actual quote."

Frequently asked questions
Why do sewer repair quotes vary so much?
Because the method varies. Clearing a clog, lining a pipe, and excavating a collapsed run are entirely different jobs with entirely different labor and equipment. A quote made without camera footage is a guess — which is why we scope every line before quoting and show you the footage.
Does homeowners insurance cover sewer line repair?
Usually not for wear, age, or root damage — the most common causes. Some policies offer optional service-line riders that do cover it. Check your policy for a service line endorsement, and ask us for camera footage and a written diagnosis; insurers require documentation either way.
Is trenchless repair cheaper than excavation?
Often, once you count everything. Even when trenchless pricing is similar per foot, excavation adds restoration costs — landscaping, concrete, sometimes street cuts and traffic control. Trenchless avoids most of that, which is why we treat digging as the last resort, not the default.
How do I get an exact price instead of a range?
A camera inspection. Once we see the line — material, condition, problem, location, depth — we can quote the actual job instead of a national average. Call (303) 476-3160 and we will scope it, show you the footage, and give you a real number.
