North Park's dense urban grid, mature street trees, and pre-war construction create a challenging environment for sewer infrastructure. Original clay tile and cast iron sewer laterals running from homes to the city main must navigate under sidewalks, past tree roots, and through soil that has settled and shifted over decades. Root intrusion from North Park's abundant mature trees is one of the most common sewer problems in the neighborhood — roots seek out moisture and nutrients in sewer pipes, entering through joints and cracks and eventually blocking flow entirely.Homewerx inspects North Park sewer laterals with HD cameras that document every foot of pipe from the cleanout to the city connection. We identify root intrusion severity, pipe material and condition, joint separations, bellies, and any other defects. For North Park's many multi-unit properties, sewer inspection is especially important because a single lateral often serves multiple units — a failure affects all tenants simultaneously.
