Mature trees, older lots and what they do to underground pipes
Many Forest Hills blocks are shaded by large, long-established trees, and that is wonderful on a summer day but hard on buried pipe. Roots seek out moisture and tiny gaps, so an older clay or cast iron sewer connection can slowly fill with growth.
Homeowners often notice it as a gurgle in a toilet, a slow drain that returns a few weeks after cleaning, or a damp patch in the lawn. Because these signs overlap with other problems, a camera inspection gives a clear picture before any decisions about lining or replacing the pipe.
