Don't dig blind. Look first.
Out here in the box, the ground itself works on sewer lines. The clay soil swells and shrinks with the seasons, flexing sixty year old pipe year after year, and when backups start, the question is always the same. What's actually down there? Roots at a joint? A section that shifted? A belly where the soil settled? Grease from decades of kitchens? Every answer means a different fix at a very different cost, and nobody, no matter how experienced, can tell you which one from the surface.
The camera can. A sewer inspection runs a small camera through the line from cleanout to street, live video of every foot, and what's on the screen settles the argument. You see the roots, or the crack, or the standing water in a low spot, or a line that's rougher than new but honestly still working. No interpretation required, no trust required either, the footage is right there, and it gets saved. In East County's older housing stock, that video is the difference between fixing the real problem and paying for someone's theory.
Get the look before the big decisions. Before a major repair gets approved. Before an older El Cajon house changes hands. Before another year of clockwork backups. What's under the yard stops being a mystery in about ten minutes, and everything after that is your call, made on evidence.
"We saw the crack on the screen ourselves. No guesswork, no upsell."
