A sewer drain backup can turn into a major property emergency in a matter of minutes. Sewage water can damage flooring, drywall, furniture, and personal belongings while also creating serious sanitation concerns. When wastewater enters your home, fast professional cleanup is essential to limit damage and restore a safe environment. Kelmann Restoration provides emergency restoration and cleanup services from sewer drains that are backing up in New Berlin, Sheboygan, Madison, and Wauwatosa, WI, to help homeowners recover quickly after sewer and water damage incidents.

A sewer drain backup occurs when wastewater cannot properly flow through your plumbing or sewer line and instead backs up into sinks, toilets, floor drains, or basements. These situations are often caused by clogged sewer lines, tree root intrusion, heavy rainfall, damaged pipes, or aging plumbing systems. In some cases, overwhelmed municipal sewer systems can also contribute to backups during severe storms.
Because sewage water contains harmful contaminants, cleanup requires more than simply removing standing water. Professional mitigation, sanitation, and drying are necessary to help prevent lasting damage and contamination throughout the property.
Sewer backups are not always immediate or obvious. Recognizing the warning signs early can help minimize damage and reduce cleanup costs. If you notice any of these issues, it is important to act quickly before the problem worsens:
