We at The Wheaton Team recommend Buyers perform sewer scopes when purchasing their next home. Sewer scopes cost buyers around $150 to evaluate the integrity of the sewer line and provide Buyers with a video reference of the sewer line. Many times, the sewer line will function properly, however there are instances where the line will need to be cleaned or repaired/replaced. These sewer repairs can range from the low end at $250 to the high end of $20,000. Sewer issues are not to be taken lightly and do not get better over time so we recommend knowing before you buy whether there are issues to be addressed.
