In a sewer inspection, we test the condition of your sewer line from the house to the street.  In new homes, sewer lines can be bellied and compressed with heavy construction equipment when the house was being built.  In older homes, tree roots and corrosion are the biggest threats for potential issues.  Clogs causing backups can happen anytime.  Make sure you understand the condition of your sewer line before it backs up and you have sewage in your house When sewer lines are damaged or blocked, sewage can back up into the home. This water contains a variety of biological hazards that can cause intestinal, lung, and other infections. The moisture also creates the perfect growing environment for mold. Additionally, if backups go unnoticed, the issues can spread and expose people in the home to further health risks.
