Tree root intrusion occurs when tree roots enter a sewer pipe through a crack, loose joint, or damaged section while searching for moisture. Once inside, the roots continue growing, restricting wastewater flow and damaging the pipe.
Left untreated, root intrusion can lead to recurring clogs, sewage backups, and expensive repairs. Campbell & Company locates the problem, removes the roots, and restores your sewer line.
Understanding Tree Root Intrusion
What Is Tree Root Intrusion?
Tree roots naturally grow toward water sources. Even small openings in a sewer line allow moisture to escape into the surrounding soil, attracting nearby roots.
Older clay, concrete, and cast iron sewer pipes are especially vulnerable because joints and aging materials provide easy entry points.
Why Tree Roots Grow Toward Sewer Lines
Roots are attracted by:
- Moisture escaping from damaged pipes
- Nutrient-rich wastewater
- Cracks and separated pipe joints
- Damp soil surrounding leaking sewer lines
Common Causes of Tree Root Intrusion
Aging Sewer Pipes
As sewer pipes age, joints loosen and pipe materials deteriorate, allowing roots to enter.
Pipe Damage
Ground movement, corrosion, freezing temperatures, and excavation can crack or separate sewer pipes.
Nearby Trees
Large trees with extensive root systems spread well beyond the trunk. Planting them close to underground sewer lines increases the likelihood of future root intrusion.
Signs of Tree Root Intrusion
Slow Drains Throughout the Home
If multiple sinks, tubs, or toilets drain slowly, the blockage is frequently located in the main sewer line.
Frequent Sewer Backups
Wastewater backing up through toilets, tubs, or floor drains usually indicates a restriction affecting the entire sewer system.
Gurgling Plumbing Fixtures
Roots trap air inside the sewer line, causing bubbling or gurgling sounds when water drains.
Foul Sewer Odors
Persistent sewer odors indoors or outside can indicate wastewater or sewer gas escaping through a damaged pipe.
Lush or Soggy Areas in the Yard
Greener grass or wet areas above the sewer line may indicate an underground leak feeding nearby roots.
Risks of Ignoring Tree Root Intrusion
Tree roots continue growing until the blockage is removed.
Ignoring the problem can result in:
- Complete sewer blockages
- Cracked or broken sewer pipes
- Sewage backups inside the home
- Water damage
- Landscape excavation
- Higher repair costs
Finding the problem early limits damage before replacement becomes necessary.
How Professionals Diagnose Tree Root Intrusion
Sewer Camera Inspection
A professional sewer inspection uses a waterproof camera to locate root growth, identify damaged pipe sections, and determine the condition of the sewer line.
Drain and Sewer Evaluation
After locating the intrusion, technicians determine how much damage the roots have caused and recommend the most effective repair.
Tree Root Intrusion Repair Options
Mechanical Root Removal
Specialized cutting equipment removes roots and restores wastewater flow.
Hydro Jetting
High-pressure water clears remaining roots, grease, and debris from the pipe walls.
Pipe Repair
If the damage is limited, localized sewer repair restores the affected section without replacing the entire sewer line.
Trenchless Sewer Repair
Pipe lining seals cracks and creates a new pipe inside the existing sewer line with minimal excavation.
Sewer Line Replacement
Extensive root damage or collapsed pipes sometimes require complete replacement.
Preventing Future Root Intrusion
Regular Sewer Inspections
Routine inspections identify developing root growth before it blocks the sewer line.
Preventative Drain Maintenance
Periodic cleaning removes buildup that allows roots to collect debris inside the pipe.
Smart Landscaping
Planting trees farther from underground utilities reduces the chance of future root intrusion.
Sewer Line Upgrades
Modern sewer materials provide stronger resistance to root intrusion than many older pipe systems.

Schedule OnlineFrequently Asked Questions
Yes. As roots continue growing inside the pipe, they collect debris until wastewater can no longer flow through the sewer line.
Homes with mature trees near the sewer line benefit from periodic camera inspections or whenever recurring drain problems develop.
Yes. Hydro jetting removes smaller roots and cleans debris from inside the pipe. Larger root masses may require mechanical cutting first.
They can if damaged pipe sections remain unrepaired. Repairing or lining the sewer pipe greatly reduces future intrusion.
Yes. Pipe lining seals cracks and joints that previously allowed roots to enter.
Fast-growing trees with aggressive root systems are the most likely to invade underground sewer pipes.
