Sewer problems don't always mean the entire system needs to be replaced. A professional inspection can help determine whether cleaning, spot repair, or replacement is appropriate. Signs of a damaged sewer line may include recurring drain backups, multiple slow drains, sewer odors, unusual sounds from drains, or problems that return after repeated cleaning.
Older cast-iron drain systems can also deteriorate over time, particularly beneath slab foundations. A sewer camera inspection can help identify cracks, deterioration, obstructions, and other problems before deciding on the appropriate repair.
