Sewer Line Services Offered in Longmont, CO
Sewer Line Inspection and Camera Diagnostics
You can't fix what you can't see. That's why every serious sewer job starts with a good look inside the pipe.
Our sewer camera inspection service sends a waterproof, high-resolution camera down the line so we can see exactly what's going on. No guesswork, no digging blind. A sewer line video camera inspection helps us:
- Pinpoint blockages and clogs
- Spot tree root intrusion
- Find cracks, breaks, and offset joints
- Locate bellies (low spots where waste pools)
- Confirm a repair worked before we backfill
Buying a home? A sewer scope inspection for home buyers in Longmont is one of the smartest few hundred dollars you'll ever spend. Older homes near Downtown Longmont or the Eastside can hide serious pipe problems that a standard home inspection misses. We scope the line, show you the footage, and tell you straight what we see, so you can negotiate or walk away with confidence.

Sewer Line Repair and Replacement
Not every problem needs a full replacement. Sometimes a targeted sewer line repair does the trick, a spot repair on a cracked section, a re-seated joint, or a fresh cleanout.
But when a pipe has collapsed, corroded through, or sagged badly, replacement is the honest answer. We'll walk you through both options, show you the camera footage, and let you decide with all the facts. If you've got a sewer backup repair emergency, we prioritize getting flow restored fast, then plan the permanent fix.
Trenchless Sewer Line Solutions
Digging up your whole yard used to be the only way to replace a sewer main. Not anymore. Our trenchless sewer repair methods fix or replace the line with little to no excavation.
Pipe lining (CIPP): We insert a resin-coated liner into the old pipe and cure it in place. It hardens into a smooth, seamless new pipe inside the old one, great for cracks, root intrusion, and corrosion when the host pipe still holds its shape.
Pipe bursting: For pipes too far gone to line, we pull a new pipe through the old one while breaking the old pipe outward. It's a full replacement with just two small access points.
With trenchless sewer line repair, you keep your driveway, sidewalks, and landscaping intact, the job finishes faster, and the new pipe often outlasts the original.
Sewer Line Cleaning and Drain Clearing
Sometimes the pipe is fine, it's just clogged. Routine sewer cleaning keeps things flowing and heads off backups before they start.
For tough buildup, hydro jetting blasts the inside of the pipe with high-pressure water. It scours out grease, sludge, and even tree roots, cleaning the sewer main back to bare pipe. We reach for hydro jetting over a mechanical snake when a clog keeps coming back or when grease and roots coat the walls, a snake punches a hole through: jetting cleans the whole thing.

Common Sewer Problems We Fix in Longmont Homes
Our soil and older housing stock create some predictable trouble:
- Tree root intrusion from the tree-lined streets around Prospect New Town and older neighborhoods
- Orangeburg pipe failure in mid-century homes
- Bentonite clay soil movement that shifts pipes and creates bellies
- Pipe corrosion and collapsed sections in aging lines
- Backups during heavy household use
- Broken cleanouts and improper pipe slope
Watch for warning signs: slow drains throughout the home, recurring clogs, gurgling, sewer odors, and soggy patches in the yard. Catch these early and you'll usually save money.
Sewer Line Replacement Costs and What Affects Them
Everyone wants a number, and we get it. But the honest truth about main sewer line replacement cost is that it depends on several things:
- Length and depth of the line
- Pipe material and how bad the damage is
- Repair method, traditional excavation vs. trenchless
- Pipe lining vs. pipe bursting
- Accessibility, tree root removal, and permits
- Emergency vs. scheduled service
A camera inspection first is non-negotiable. It's the only way to give you an accurate estimate instead of a wild guess.
