Trees add beauty, shade, and value to your property.
Unfortunately, they can also become one of the biggest threats to your home’s underground plumbing.
Every year, homeowners throughout San Diego experience sewer backups, recurring drain problems, and expensive sewer repairs caused by tree roots growing into underground sewer lines. The surprising part is that healthy trees aren’t “looking” for your pipes—they’re simply following one thing they naturally seek: water.
At Ascend Plumbing, we’ve helped homeowners throughout San Diego, La Jolla, Mission Hills, Poway, Chula Vista, Santee, Clairemont, Rancho Bernardo, and communities across San Diego County identify root intrusion before it became a plumbing emergency. Using advanced sewer camera inspections and modern drain cleaning technology, we can accurately diagnose root-related sewer problems and recommend the most effective repair solution.
If your home has mature landscaping—or was built several decades ago—this is one plumbing issue every homeowner should understand.
Why Tree Roots Are Attracted to Sewer Pipes
Tree roots don’t intentionally seek out sewer pipes.
They’re searching for moisture and nutrients.
Older sewer lines often develop tiny cracks, loose joints, or worn seals that allow small amounts of moisture to escape into the surrounding soil.
Even a microscopic opening can attract nearby roots.
Once a root reaches that moisture source, it continues growing.
Over time, what began as a hair-thin root can become a dense root mass capable of slowing wastewater flow, blocking the pipe, or even breaking it apart.
Which Homes Are Most at Risk?
While any property can experience root intrusion, some homes are more susceptible than others.
Your risk may be higher if:
- Your home was built before the 1980s
- You have mature trees near your sewer line
- Your property has older clay or cast iron sewer pipes
- You’ve experienced recurring drain problems
- Your neighborhood has large established landscaping
- The sewer line has never been inspected
Many older neighborhoods throughout San Diego have beautiful, mature trees—and aging sewer systems beneath them.
Warning Signs of Root Intrusion
Tree roots rarely cause an immediate blockage.
Instead, symptoms usually develop gradually.
Watch for:
Slow Drains Throughout the Home
When several fixtures begin draining slowly, the problem may involve the main sewer line rather than an individual drain.
Frequent Toilet Backups
If plunging seems to solve the problem only temporarily, roots may be partially blocking the sewer line.
Gurgling Sounds
Air trapped behind a partial blockage often creates bubbling or gurgling noises.
Sewer Odors
Damaged sewer lines can allow unpleasant odors to escape around the property or inside the home.
Wet Areas in the Yard
A damaged sewer line may leak enough moisture to create unusually green grass or damp spots above the pipe.
Recurring Drain Cleaning
If your drains improve after cleaning but clog again a few months later, tree roots may still be growing inside the sewer line.
How Do Plumbers Know If Roots Are the Problem?
Years ago, plumbers often had to dig up sewer lines to determine the cause of recurring problems.
Today, technology makes diagnosis much easier.
A professional sewer camera inspection allows our technicians to see exactly what’s happening inside your sewer line.
The camera can identify:
- Tree roots
- Pipe cracks
- Offset joints
- Pipe corrosion
- Grease buildup
- Broken sections
- Collapsed piping
Rather than guessing, you’ll know exactly what’s causing the problem before any repairs begin.
Can Tree Roots Be Removed?
In many cases, yes.
The appropriate solution depends on how much damage has already occurred.
Options may include:
Professional Root Removal
Specialized equipment can remove many root intrusions while restoring normal flow.
Hydro Jetting
Hydro jetting uses highly pressurized water to cut through smaller roots and thoroughly clean the inside of the sewer line.
This process also removes grease, sludge, soap buildup, and other debris that often accumulates around root growth.
Spot Repairs
If roots have damaged only one section of pipe, a localized repair may be all that’s needed.
Trenchless Sewer Repair
Depending on the condition of the sewer line, trenchless repair methods may restore damaged piping while minimizing excavation.
Epoxy Pipe Restoration
In qualifying situations, epoxy pipe restoration can rehabilitate existing pipes from the inside without extensive digging.
Ascend Plumbing has invested in advanced epoxy pipe restoration technology that remains uncommon among many plumbing companies in the San Diego area, giving homeowners additional repair options when appropriate.
Can Tree Roots Be Prevented?
While no solution can guarantee roots will never return, homeowners can reduce the risk by:
- Scheduling periodic sewer camera inspections
- Addressing recurring slow drains early
- Avoiding flushing wipes and grease
- Repairing damaged sewer lines promptly
- Monitoring mature trees near sewer easements
- Performing preventative drain maintenance
Routine inspections often identify developing problems before major damage occurs.
Common Mistakes Homeowners Make
Tree root problems usually become expensive because homeowners unintentionally wait too long.
Common mistakes include:
- Assuming recurring clogs are “normal”
- Using chemical drain cleaners repeatedly
- Ignoring sewer odors
- Waiting until sewage backs up
- Never inspecting older sewer lines
- Delaying repairs after roots are discovered
The earlier root intrusion is addressed, the more repair options are typically available.

Did You Know?
Tree roots can travel dozens of feet in search of moisture. Once they enter a sewer pipe, they continue growing, trapping toilet paper, grease, soap residue, and other debris until wastewater flow becomes restricted.
Ascend Expert Tip
If your home has mature landscaping and you’ve experienced more than one sewer backup or recurring drain problem, don’t keep paying for the same drain cleaning every few months. A sewer camera inspection can identify whether tree roots—or another issue—are causing the problem so you can invest in the right long-term solution.

Frequently Asked Questions
Will cutting down a tree solve the problem?
Not necessarily. Existing roots may remain in the soil for years, and damaged sewer pipes may still require repair.
How often should older sewer lines be inspected?
If your home has mature trees or an older sewer system, periodic sewer camera inspections can help identify developing issues before they become emergencies.
Can hydro jetting remove tree roots?
Hydro jetting can remove many smaller roots and thoroughly clean the inside of the pipe. However, the best solution depends on the condition of the sewer line and the extent of the damage.
Is trenchless sewer repair an option?
In many situations, yes. Depending on the condition of your sewer line, trenchless repair methods or epoxy pipe restoration may provide effective alternatives to traditional excavation.
