Expert Excavation & Sewer Repair
Expert Main Sewer Line Services in Metro Atlanta
Your main sewer line is the single exit point for every sink, shower, and toilet in your home. When it fails, the results are messy, unhygienic, and deeply stressful. At A&G Plumbing, our specialized sewer division handles everything from localized spot repairs to full yard excavations and open-trench sewer line replacements.
Symptoms of a Main Sewer Line Failure
Unlike an isolated sink clog, a main sewer line blockage affects the entire house. You likely have a main line issue if you experience:
- Multiple Backup Points: Water backing up into the bathtub when you flush the toilet or run the washing machine.
- Lush, Green Patches of Grass: Sewage acts as a powerful fertilizer. Unusually green or soggy patches in your yard directly above the sewer line heavily indicate a crack or leak.
- Sewer Gas Odors: A persistent smell of raw sewage in your yard or basement floor drains.
- Recurring Plunging: Needing to constantly plunge toilets on the lowest level of the home.
Signs Your Main Sewer Line is Failing
Don’t wait for a complete backup. Contact us immediately if you notice:
- Multiple Slow Drains: If your toilet, bathtub, and sink are all draining slowly at the same time, the blockage is in the main line.
- Gurgling Sounds: Hearing a bubbling or gurgling noise from your toilet when you run the bathroom sink means trapped air is trying to escape.
- Sewer Gas Odors: A persistent smell of raw sewage in your yard or basement floor drains.
- Recurring Plunging: Needing to constantly plunge toilets on the lowest level of the home.
Root Intrusions, Bellied Pipes, and Collapse
In Metro Atlanta, particularly in older neighborhoods with mature trees, **tree root intrusion** is the number one cause of sewer line failure in clay or cast iron pipes. Roots seek out the moisture and nutrients inside the pipe, eventually crushing it.
We never guess when it comes to sewer repair. We run a high-definition **sewer camera inspection** down the line to visually identify whether the issue is roots, a “bellied” (sagging) pipe holding waste, or a complete structural collapse. We show you the footage so you can make an informed decision.
Open-Trench Sewer Line Replacement
When a sewer line is too compromised, bellied, or root-invaded to be cleared, our excavation crew performs open-trench replacement — the most reliable, long-lasting solution available. We expose the damaged pipe, remove it entirely, and install brand-new PVC, properly graded and bedded from scratch. This eliminates bellied sections, restores correct slope, and delivers decades of reliable service that no patch method can match.
If the line has a limited, localized issue, we can also perform minimal-footprint spot repairs — cutting a small access point directly over the problem area to achieve a targeted fix with less disruption.

Major Sewer Repair FAQs for Atlanta Homes
What causes an underground sewer pipe to collapse?
Older pipes made of clay, cast iron, or Orangeburg (tar paper) naturally deteriorate over decades. Soil shifting, heavy ground traffic, earthquakes, and especially tree roots wrapping around and crushing the pipe are the most common culprits. Once a pipe loses its structural integrity, the dirt above caves in, completely blocking the flow of sewage.
How do you decide whether to do a spot repair or full replacement?
We run a high-definition sewer camera inspection before any repair or replacement. If the damage is limited to one section, a spot repair (cutting a small access point directly over the problem) is often sufficient and significantly less disruptive. If the line has multiple failure points, widespread root intrusion, or is seriously bellied, a full open-trench replacement is the more cost-effective long-term solution.
Will I be without bathrooms during a sewer replacement?
Usually, water and sewer service only need to be shut off for a few hours on the specific day the old pipe is disconnected and the new pipe is tied in. Our excavation crews act fast to ensure you are never without essential facilities overnight.
