You’ll likely need sewer line replacement if you're experiencing recurring clogs, slow drains, foul odors, soggy patches in the yard, or sewage backing up into your sinks or tubs. These are signs of a deeper issue within your sewer line, often due to root intrusion, pipe collapse, or corrosion—especially in older homes throughout areas like Roswell, Sandy Springs, or Dunwoody. New installations are also essential for new construction projects or property expansions needing updated infrastructure.
