Ultimate Guide to Sewage Backup Cleanup: What You Should Know

Sewage backup is one of the most unpleasant and hazardous problems homeowners can face. It not only causes significant property damage but also poses serious health risks.

What Is Sewage Backup?
Sewage backup occurs when wastewater from toilets, sinks, or other plumbing fixtures can’t drain properly and reverses into the home.

Clogged Pipes
Accumulation of grease, hair, or foreign objects can block drains.
Tree Roots
Roots can grow into sewer lines, cracking pipes and restricting flow
Aging Sewer Systems
Older homes often have outdated pipes that are more prone to failure.
Heavy Rainfall or Flooding
Stormwater can overload city sewer systems, causing backups.
Collapsed Sewer Lines
A break in the main sewer line can lead to immediate backup.

Foul odors coming from drains or toilets
Gurgling noises from plumbing fixtures
Slow drains in multiple fixtures
Sewage water pooling in tubs or basements
Water backs up when using appliances (e.g., a washing machine causes a toilet overflow)
Recognizing these signs early can prevent severe damage and costly repairs.
