A sewage backup is one of the messiest and most dangerous kinds of water damage, because the water carries bacteria and other contaminants. This is not a cleanup to handle on your own. Sewage cleanup safely removes the waste water, disinfects every surface it touched, and dries the area. WaterDamageOnCall connects you with trusted local restoration pros, 24/7.

Why sewage needs a pro
Sewage is category three water, also called black water. It can carry bacteria, viruses, and parasites, so it needs protective gear, professional disinfection, and safe disposal. Porous materials that soaked it up, like carpet and padding, usually have to be removed. Trying to clean it with a mop and bucket can spread the contamination and put your family at risk.
Common causes of a sewage backup
- A clogged or collapsed main sewer line
- Heavy rain overwhelming the city system
- Tree roots growing into the pipe
- A failed septic system
- A blockage that pushes waste back up a drain or toilet
What to do while you wait
Keep people and pets away from the affected area, avoid using drains and toilets that back up, and do not touch the water without protection. Then get a professional out as fast as possible.

Does insurance cover a sewage backup? Some policies cover it only if you carry a sewer backup add on, so coverage varies. A pro can document the loss for your claim.
Can the affected items be saved? Hard surfaces can usually be cleaned and disinfected. Soft, porous items that soaked up the water often have to be thrown out for safety.
