When we represent buyers and it’s time to schedule home inspections, we always discuss several add-on inspections buyers may want to consider ordering: tests for radon and mold, and a sewer line scan.
Check out this video from Zsako Home Inspections, which shows tree roots that have penetrated a sewer line.
“Why you should consider getting a sewer video scan! This is from a Sewer Scan done by Zsako Home Inspections. Over 50% of the sewer scans performed reveal one or more problems with the sewer line. Home older than 25 years of age are about twice as likely to have an issue.”
