Warning Signs You Need Drain or Sewer Cleaning in Longmont
Most drain problems warn you before they turn into a flooded basement. Call when you see these:
Slow drains
Water pooling in a sink, tub, or shower. One slow drain may be a local clog — several slow at once means main line trouble.
Gurgling sounds
Noise from a drain or toilet means air is trapped behind a blockage downstream.
Sewer smell
An odor inside the home or near a floor drain points to a line not flowing properly — often a cracked joint venting gas.
Backups in the lowest fixture
Water rising in a basement floor drain or a ground-level shower is a strong signal of a main sewer line blockage.
One fixture affecting another
Flushing the toilet makes the shower gurgle or the tub back up — waste cannot get past a blockage further down the shared line.
Soggy or unusually green yard patches
A cracked lateral is feeding the surface from below.
Repeat clogs
Clearing the same drain again and again means the cause is still in the pipe — roots, grease buildup, or a damaged section that a snake only pokes a hole through.
Why Drain and Sewer Lines Fail in Longmont Homes
Longmont's drain problems come from the ground up, not from bad habits.
Expansive clay soil
The Colorado Geological Survey identifies swelling clay as one of the state's most damaging geologic hazards. Pierre Shale and other expansive clays beneath Longmont swell when wet and shrink when dry. That movement cracks pipe joints, pulls connections apart, and creates pipe bellies where waste pools instead of draining. A clog that keeps coming back in the same spot often has a belly underneath it that cleaning alone will not resolve.
Tree root intrusion — cottonwoods, Siberian elms, and boxelders
These trees are common throughout Longmont's older neighborhoods and are among the most aggressive root growers in Colorado. They find every hairline crack in aging clay and cast iron pipe and grow into a thick mass that traps waste and chokes the line. The City of Longmont regularly finds roots entering sewer mains from private service lines — on the homeowner side of the connection, not the city main.
Aging pipe from the late 1800s through the 1980s
Old Town Longmont and the historic districts have clay tile and cast iron sewer laterals that are now 80 to 140 years old. Clay cracks. Cast iron corrodes and roughens on the interior, giving grease and debris more surface to cling to. Many of these lines have never been camera-inspected.
Long-term damage from the 2013 St. Vrain Creek flood
The flood saturated soil across Longmont and created lasting stress on underground sewer infrastructure — particularly in neighborhoods on the west side near the creek corridor. Pipe joints that shifted during the flood event continue to present root intrusion points and collapse risk. Homes in these areas benefit from a camera inspection even when no symptoms are visible.
Freeze-thaw cycles and hard water mineral scale
Longmont's elevation produces frequent temperature swings that stress pipe joints through every winter. Hard mountain water leaves calcium and magnesium scale on pipe walls year after year, narrowing the interior and creating rough surfaces that trap grease and debris faster than a clean pipe would.

Drain and Sewer Services in Longmont CO
Every visit starts with finding the real cause. Flat rate in writing before we touch anything. Right tool for what we actually find.
Rooter Service in Longmont CO — from $100
A motor-driven cable — rooter service — feeds into the drain line and breaks through the clog, then pulls it out rather than just pushing a hole through it. For a fresh, single-drain blockage from hair, soap, or soft grease, rooter service is the right first tool and we will not push you past it when it solves the problem completely.
Rooter service is also the right emergency call for a main line backup at a bad hour — it restores flow fast so your home is usable again while we assess whether the underlying condition needs a deeper fix.
Hydro Jetting in Longmont CO — $300 to $600
Hydro jetting sends water at up to 4,000 PSI through a rotating nozzle that scours the full pipe wall — removing grease coating, mineral scale, and root debris that a cable breaks apart but leaves on the wall. It is the right call for lines that keep clogging back, older Longmont homes with clay or cast iron pipe roughened by corrosion, and commercial kitchen lines under heavy daily load.
We camera the pipe before jetting — always. Old clay pipe that has deteriorated cannot always handle jetting pressure. We check the condition first and set the right pressure for the material, which protects fragile lines while still getting them clean.
$300 – $600Drain Clearing Service in Longmont CO — from $100
Drain clearing covers the full range of single-fixture blockages — kitchen sink drains, bathroom drains, shower and tub drains, floor drains, and laundry lines. We identify the cause at each fixture before choosing a method, so the clearing addresses what is actually blocking the line rather than the nearest point of resistance.
Sewer Camera Inspection in Longmont CO — $125 to $300
A waterproof camera runs down the sewer lateral from the cleanout and shows you the inside of your pipe in real time — roots, cracks, shifted joints, pipe bellies, and scale coating — before we recommend any work. You see what we see. A surface locator marks the exact depth and location of any problem.
Camera inspection is essential before purchasing any Longmont home built before 1985, after any recurring backup in Old Town or the West Side Historic District, and after flood-area homes with no inspection history.
$125 – $300Main Sewer Line Cleaning in Longmont CO — $175 to $500
When more than one drain backs up simultaneously, the blockage is in the main sewer lateral — the pipe that carries all household waste to the city main under the street. We camera first, clear with the right method for what we find, and confirm the line is open end to end with a post-cleaning camera pass before we leave.
$175 – $500Tree Root Removal from Sewer Lines in Longmont — $300 to $600
Roots are the leading cause of repeat drain problems in Longmont's older neighborhoods. We cut the root mass out of the pipe with a mechanical cutting tool, then scour the pipe walls with hydro jetting to remove the debris a snake or cable leaves behind. A post-service camera confirms complete clearance. For properties in Old Town and the historic districts with known cottonwood, elm, or boxelder root pressure, an annual visit prevents regrowth from reaching blockage stage before the next growing season.
$300 – $600Kitchen Drain Cleaning Services in Longmont — from $100
Grease, cooking oil, food waste, and coffee grounds accumulate past the trap and harden against scale-roughened pipe walls. Hard mountain water in Longmont accelerates the bonding of grease and mineral deposit into a compound that a cable only pokes through. We clear the line at the source and jet it when the walls are coated — so the clean holds for months rather than weeks.
Bathroom and Shower Drain Cleaning Service — from $100
Hair and soap bind in the trap and trap arm. We remove the clog completely rather than dissolving the surface layer with chemicals that accelerate corrosion in Longmont's older cast iron and clay pipe. If the shower, tub, and sink all slow at the same time, we check the main line — that pattern in Longmont almost always points to the lateral, not individual fixtures.
Sewer Line Repair in Longmont CO — $1,500 to $15,000
When the camera finds a cracked, collapsed, root-wrecked, or bellied pipe, cleaning will not hold and the line needs a real repair. This is a common finding in Old Town and the West Side Historic District — clay tile laterals from the early 1900s that have cracked at joints, shifted from clay soil movement, or collapsed under decades of root pressure.
We show you the damage on camera and give you a written price before any work begins. No pressure to decide on the spot.
Most Longmont sewer line repairs do not require excavating your yard. Pipe bursting threads a new pipe through the path of the old one. Pipe lining hardens a resin sleeve against the inside wall, creating a smooth new interior without full excavation. Both methods work from two small access points.
We excavate only when the pipe has fully collapsed or when a belly is too severe for trenchless methods to correct the slope — and we explain exactly why when that is the honest answer.
Is the Sewer Backup the City of Longmont's Problem or Yours?
The City of Longmont maintains over 300 miles of sanitary sewer mains under the streets. The service lateral — from your home to the city main — is the property owner's responsibility from the foundation to the city connection point.
A simple rule: if sewage backs up into your basement only when water is running inside the home, the problem is almost certainly in your service lateral, not the city main. If the city main is blocked, the city dispatches a crew. If a city main issue causes damage through your service line, the city directs you to file a claim through its Risk Management Office.
City water utilities operate weekdays from 8 AM to 5 PM. After hours, Longmont residents are directed to contact the Police Dispatch, who then send a utility technician for confirmed main line issues.
For the lateral that belongs to you — you do not have to wait for business hours. Roko Drain Cleaning answers 24 hours a day, every day of the year.
Commercial Drain Cleaning in Longmont CO
Restaurants, retail businesses, office buildings, apartment complexes, and medical facilities in Longmont cannot afford a drain backup during operating hours. We clear commercial drain lines, service grease traps, and jet commercial kitchen lines on a schedule built around your business hours — not a next-available window.
The City of Longmont asks property owners to keep grease traps maintained and clean. We help restaurants and food service businesses stay ahead of backups and in compliance with grease trap requirements — before a health inspection, not after.
For apartment complexes and multi-tenant buildings in and around Old Town, we handle individual unit emergencies and set building-wide maintenance schedules with camera reports for every address.

What can push the price higher in Longmont:
- Clay tile or cast iron pipe too fragile for standard jetting pressure — requires lower-pressure approach or repair first
- No accessible cleanout — we reach through a roof vent or by pulling a toilet
- Root mass requiring mechanical cutting before hydro jetting
- Pipe belly from clay soil movement — cleaning holds temporarily but repair is often the better long-term answer
- Flood-area pipe with multiple offset joints that need sequential clearing

How to Prevent Drain and Sewer Clogs in Longmont Homes
A few habits that matter more in Longmont than in most Colorado cities:
- Keep grease out of the kitchen sink. Grease bonds with hard water mineral scale on the pipe wall faster here than in cities with softer water.
- Use a screen in every shower and tub. Hair is the leading cause of bathroom drain blockages and the easiest to prevent.
- Only toilet paper goes in the toilet. Wipes — even labeled flushable — catch on root masses in Longmont's older lines and cause backups.
- Keep large thirsty trees away from the sewer lateral. Cottonwoods, Siberian elms, and boxelders should not be planted near the line.
- Know where your cleanout is. Finding it before an emergency saves time when a technician arrives.
- Clear slow drains early. A slow drain is the cheapest version of the problem. A full backup is the most expensive.
For Old Town homes and any Longmont property with large trees near the lateral, annual sewer cleaning is the most cost-effective approach to avoiding an emergency.
