Sewer backups typically occur when something blocks or restricts the main sewer line. One of the most common causes is tree roots, which can grow into small cracks or joints in the pipe and gradually block wastewater flow. Over time, roots can also cause pipes to separate or collapse.
Another frequent cause is sludge and buildup from everyday household use. Materials like grease, soap residue, food particles, and personal care products can accumulate along the pipe walls, eventually narrowing the passage and increasing the risk of backups. Defective or aging sewer pipes—especially those made from older materials—can also crack, corrode, or shift, creating ongoing drainage problems.
Common warning signs include frequent drain backups, slow drains throughout the home, and persistent sewage odors. Regular sewer inspections, including sewer camera inspections, can identify developing problems early and help prevent unexpected backups and more extensive repairs.
