Sewer Line & Water Main Repair in Fort Collins, CO
Sewer backups, water main leaks, root intrusion, and line collapses are the kinds of problems that can't wait. We handle sewer and water main work in Fort Collins with camera inspection to confirm the problem before we dig — and full permit handling so you're covered.
Warning Signs
Signs You Have a Sewer Line or Water Main Problem
Main line problems tend to announce themselves — you just need to know what you're seeing. Here's what to watch for:
Sewer Line Warning Signs
Multiple Drains Backing Up at Once
When two or more drains throughout the house slow down or back up simultaneously, the blockage is in the main sewer line, not in individual fixture drains.
Sewage Odors Inside or in the Yard
Sewer gas odors inside the home or outside along the line path indicate a crack, offset, or broken section allowing gas to escape.
Wet Areas or Sinkholes in the Yard
A broken sewer line can create soft, wet patches or depression areas in the yard along the line path — especially after dry periods when the ground would otherwise be firm.
Frequent Main Line Backups
If your main line backs up more than once a year, root intrusion or structural damage is likely the cause. Cleaning treats the symptom; repair treats the problem.
Water Main Warning Signs
Unexplained High Water Bills
A water bill that's significantly higher than normal without obvious cause — no new appliances, no change in usage — is a classic sign of an underground water line leak.
Pressure Loss Throughout the House
A sudden drop in water pressure at all fixtures, not just one, can indicate a water main break or significant leak between the meter and the house.
Wet Areas in the Yard Near the Water Line Path
Unexplained wet patches in the lawn — particularly along the path from the water meter to the house — indicate a leaking water main.
Discolored Water at All Faucets
Rusty or brown water at all fixtures simultaneously can indicate main line pipe corrosion, a main break disturbing sediment, or municipal supply issues — we can help diagnose which.
What We Handle
Sewer & Water Main Services in Fort Collins
Camera Sewer Inspection
A small camera on a flexible rod lets us see exactly what's happening inside your sewer line — root intrusion, pipe offset, cracks, scale, or collapsed sections. We confirm the problem before recommending any repair approach. We won't dig based on a guess.
Sewer Line Cleaning & Root Clearing
For root intrusion and heavy buildup, we use hydro-jetting or mechanical root cutting to restore flow. Camera confirmation after cleaning ensures the line is fully clear. For smaller drain blockages that don't involve the main sewer lateral, our drain cleaning service is often the right starting point.
Sewer Lateral Repair
Targeted repair of cracked, offset, or partially collapsed sections of the sewer lateral — the line from your house to the city main. We excavate only where needed based on camera findings.
Sewer Line Replacement
When the line is too damaged for repair — significant root infiltration over a long section, pipe collapse, or severely deteriorated material — we replace the full lateral with modern PVC meeting current code.
Water Main Repair
Pinhole leaks, joint failures, and partial breaks in the water service line from the meter to the house. We locate the leak, excavate minimally, and make a lasting repair.
Water Main Replacement
When an older galvanized or deteriorated water service line needs full replacement, we pull and replace the line with modern materials — properly permitted and inspected.
Utility Locate & Permit Coordination
All main line work requires utility locates (811 call) before digging and permits from the City of Fort Collins or Larimer County. We handle both, coordinating with utilities and the city building department so you don't have to.
Our Approach
Camera Inspection First — We Don't Dig on a Guess
Main line work is expensive. Excavation costs money, disrupts your yard, and takes time. We believe — strongly — that no significant excavation should begin before a camera inspection has confirmed exactly where the problem is and what's causing it.
Here's what camera inspection tells us that we can't know otherwise: the exact location of the problem, the type of damage (root ball, offset pipe, collapsed section, scale-only blockage), the pipe material and condition of the surrounding sections, and whether there are secondary problems we should address in the same excavation. That information is worth more than its cost — it prevents unnecessary digging and prevents "while we're in there" surprises.
If you've been told you need sewer work but haven't had a camera inspection first, ask why. We won't recommend excavation without one.
Already had a camera inspection elsewhere? If you have a report or video from a prior inspection, bring it when you call. It gives us a head start on understanding what you're dealing with and can reduce the diagnostic time on our visit.
Local Context
Sewer & Water Main Issues Common in Fort Collins
Fort Collins has a mix of housing ages that creates a predictable pattern of main line issues depending on the neighborhood:
Old Town and established neighborhoods (pre-1980 construction) are where we see the most sewer lateral work. Many of these homes have original clay tile or cast iron sewer lines — materials that degrade, allow root intrusion at joints, and can crack or offset from ground movement over decades. Root intrusion from the large, established trees throughout Old Town is consistently the leading cause of sewer line problems we see in this part of the city.
Homes built 1980–2000 often have ABS plastic sewer lines that are generally more durable, but early ABS formulations are showing age now and some have developed cracking. Water service lines from this era are often copper, which can develop pinhole leaks — particularly in areas with aggressive soil chemistry.
Newer developments (Fossil Lake Ranch, Stetson Creek, Observatory Village) typically have PVC sewer and copper or PEX water service lines in better overall condition, but we do see root intrusion start to become an issue as the landscaping around these properties matures.
Water main work in Fort Collins also has to account for the city's aging distribution system in some areas — we coordinate with Fort Collins Utilities when service line work involves the connection point at the main, which has its own requirements and inspection process. For homes with issues beyond the main line — fixture leaks, pipe repairs, or remodel plumbing — see our full list of residential plumbing services.

Pricing
What Does Sewer or Water Main Work Cost in Fort Collins?
Main line work costs vary significantly based on line length, depth, pipe material, access difficulty, and whether repair or replacement is required. We can't give meaningful ranges without knowing what we're looking at. What we can tell you:
Camera inspection is a small cost that protects you from paying for unnecessary work. Written estimate before any excavation. Permit costs are included in our quote — not added on afterwards. And we'll tell you clearly if a trenchless option is viable for your situation, since that can meaningfully reduce the overall cost.

FAQ
Sewer & Water Main FAQs — Fort Collins, CO
The homeowner is typically responsible for the sewer lateral from the house to the connection point at the public main — this includes the portion under the yard and often the portion under the sidewalk or street right-of-way up to the main connection. Fort Collins has specific policies on this — we can help clarify what's your responsibility vs. the city's for your specific situation.
Trenchless methods — pipe lining (CIPP) and pipe bursting — allow sewer line repair or replacement with significantly less excavation than traditional open-cut methods. Whether trenchless is appropriate for your situation depends on pipe condition, the extent of damage, line diameter, and access. We assess trenchless viability on every camera inspection and recommend it when it's genuinely the right fit.
A basement floor drain backup is often a strong indicator of a main line problem, not a local fixture issue. Floor drains in basements are connected directly to the main drain line, so they're typically the first place you see backup when the main line is fully or partially blocked. This warrants a main line inspection.
Your home's main shutoff is typically located near where the water line enters the house — often in the basement, utility room, or crawlspace near the front foundation wall. There's also a curb stop at the meter box near the street that can be operated with a curb key. If a water main emergency occurs and you can't locate or operate the shutoff, call us immediately at (970) 672-3282 — we can walk you through it or get there fast.
If the sewer line is partially blocked but still draining slowly, limited use may be possible — keep it to essentials only and avoid any large flushes. If the line is completely backed up, stop all fixture use immediately. Using fixtures with a fully blocked main line causes sewage to back up into the lowest drains in the home. We'll advise you on what's safe based on what you describe when you call.
