In Coronado, a sewer trench is a big deal. The streets are historic, the properties sit close, and the gardens took decades. So when an original clay line under a Coronado home finally needs more than clearing, it's worth asking whether the fix can happen without the excavation. Sometimes it can, with the line rebuilt from the inside instead of dug up.
The method, pipe lining or CIPP, can often enter by way of an existing cleanout or other opening. A resin soaked liner presses against the old pipe's walls and cures into a new pipe inside it, structural and jointless. For Coronado's clay, some of it close to a century old, jointless matters a lot. Roots get in at joints, at cracks and at failed connections, and in the lined section the new pipe covers all three. The heritage trees can stay, their roots lose the way in, and the garden and street above can often be left as they are.
Here are the limits. Lining needs a pipe that still holds its shape, which shows up on camera footage. If your line qualifies, you'll see exactly why and what the process involves. If it doesn't, you'll hear that straight, with the real alternatives explained. Either way the decision is yours, made at your pace, with a licensed contractor performing the work when you say so.
