Drain Cleaning & Sewer Repair in Old Town Fort Collins
Old Town homes are some of the most character-rich in Fort Collins — and some of the most demanding on their drain systems. If your drains are slow, recurring, or backing up into the house, the pipe age and tree roots here are almost always involved.
What Makes Old Town Drain Problems Different
Old Town Fort Collins covers the blocks between College Avenue, Mulberry Street, Lemay Avenue, and the Poudre River corridor — one of the oldest continuously developed parts of the city. Homes here were built from the 1880s through the 1960s, and many of the original sewer laterals and inside drain stacks have never been replaced.
That means cast iron drain pipes inside the walls and clay sewer laterals underground — some of them 60, 70, or 80 years old. Cast iron corrodes from the inside, thins over decades, and eventually flakes and collapses. Clay pipe joints separate as the ground shifts, and once they open, the cottonwoods and elms lining Old Town streets find them within a season or two.
The mature tree canopy in Old Town is one of its defining features — and one of the top causes of sewer line failure here. A cottonwood root can travel 30 feet in search of the warmth and moisture a sewer line offers. It enters through the smallest crack in a clay joint, then grows until it splits the pipe. Cutting the root clears the line. It does not seal the crack the root came through.
We work in Old Town regularly. We know the pipe materials under these streets, the soil conditions near the Poudre, and how the old cast iron inside these homes behaves differently from the PVC in a newer build. If your drain keeps clogging in an Old Town home, the answer is almost never a longer snake — it is a camera inspection to find out what the pipe actually looks like.
How old are the sewer pipes under Old Town homes?
Most Old Town sewer laterals were laid between the 1900s and 1960s in clay or Orangeburg pipe. Clay lasts 50 to 60 years under good conditions. Orangeburg — a tar-and-fiber material used through the early 1970s — deforms and collapses with age. Many Old Town homes are at or well past the expected lifespan of their original underground piping.
The Drain & Sewer Problems We Clear Most Often in Old Town
These are not generic problems. They are the specific failures that come with Old Town's pipe age, tree species, and soil.
Root-Invaded Clay Sewer Laterals
The cottonwoods and elms along Mountain Avenue, Mulberry, and the older residential blocks are the single biggest source of sewer line calls in Old Town. Their roots travel the full length of a lateral to reach the water inside. Once a clay joint opens — from ground movement or age — roots find it fast. A drain snake clears the backup. It does not close the joint. The roots return within months. The lasting fix is a trenchless pipe liner that seals the cracks and eliminates the entry point.
Corroded and Thinning Cast Iron Inside the House
Cast iron drain stacks and branch lines inside Old Town homes reach the end of their useful life after 60 to 75 years. The pipe wall corrodes from the inside, builds up with mineral scale, and eventually flakes into the flow. What looks like a recurring clog is often scale buildup in a cast iron section that catches debris every time. A camera shows whether the pipe has enough wall left to clean or whether the section needs to be sleeved or replaced.
Collapsed or Deformed Orangeburg Pipe
Homes built in Old Town between the mid-1940s and early 1970s sometimes have Orangeburg sewer laterals — a tar-and-wood-fiber pipe that was used as a low-cost alternative after World War II. Orangeburg absorbs moisture over time, goes oval, then flat. It cannot be cleared or lined. When a camera finds Orangeburg, the only answer is full sewer line replacement. We see this regularly in the blocks around CSU and along the Riverside corridor.
Slow and Backing Drains in CSU-Area Rentals
The rental density around Colorado State University — in the blocks along Elizabeth Street, Plum Street, and City Park Avenue — means high occupancy on pipes that were not built for it. Grease, hair, and soap scum accumulate faster, and drain problems appear more frequently. Many of these properties have not had a camera inspection in years. A hydro jetting service clears the buildup completely and restores full flow where a snake only punches a hole through it.
Backups After Heavy Rain Near the Poudre
Properties close to the Cache la Poudre River corridor experience groundwater fluctuation that other parts of Fort Collins do not. After significant rain, the water table rises and can push back through older drain connections and floor drains. If your basement floor drain backs up only during or after heavy rain, this is worth investigating — it is not always a blockage and may be a backflow or drainage issue that a camera can confirm.
Main Line Backups Affecting Every Fixture at Once
When the washer, shower, and toilet all back up at the same time in an Old Town home, it is the main sewer lateral — the pipe from the house to the city connection — that is blocked or damaged. This is past the point for a store-bought snake. The line needs proper equipment and, almost always, a camera to find whether the block is debris or structural damage. Our emergency drain cleaning service responds same-day to active main line backups in Old Town.

We Know Old Pipe — Not Just Pipe in General
Working on 1920s cast iron is different from working on 2005 PVC. The wall thickness, the corrosion pattern, the way it responds to pressure — we work on Old Town pipe regularly and diagnose it correctly the first time.
Trenchless First — Your Yard Stays Intact
Old Town properties have established landscaping, mature trees, and close lot spacing. Where the line qualifies, we use trenchless lining or pipe bursting so the yard, the flagstone, and the garden are not casualties of the repair.
Camera Before Any Quote
We never quote Old Town sewer work over the phone. We camera first because the pipe age and condition here vary wildly from house to house, and no honest price exists before we see inside the line.
Drain & Sewer Only — Every Day
We are not a general plumber who does drains between water heaters and gas lines. Fort Collins Drain Specialists does drain and sewer work exclusively. The tech who shows up has cleared a line like yours many times this month.
Old Town Drain & Sewer Questions We Hear Often
In Old Town homes, a recurring backup almost always means the line has a structural problem behind the clog. Tree roots grow back through the same crack they entered. Scale catches debris again within weeks. A camera inspection shows whether the pipe needs to be lined, sleeved, or replaced — because snaking it again will produce the same result in the same timeframe.
Yes, when the pipe still holds its shape and grade. Trenchless pipe lining installs a resin liner inside the old clay pipe, sealing every crack and joint from the inside. It requires two small access points, not a trench across the yard. A camera confirms whether the pipe qualifies — a bellied or fully collapsed section still needs excavation to correct the grade.
Yes. We work with landlords across the CSU rental corridor regularly. Colorado's warranty of habitability law requires a prompt response to drain issues in occupied rentals. We respond same-day to active backups and coordinate directly with tenants when needed, so you are not stuck in the middle of a three-way scheduling problem.
The only sure way is a camera inspection. Orangeburg looks dark and layered on camera, and you can see the oval or flattened shape it develops as it deforms. Homes built between roughly 1945 and 1972 are the most likely candidates. If your home is in that range and has never had a camera inspection, it is worth knowing what is down there before a failure forces the issue.
