Sewer Line Repair in Cotati, CA

When a sewer line backs up in Cotati, we are only a few minutes from our Rohnert Park shop right next door. The older cottages near downtown Cotati were built long before the 1960s and 70s tract houses filled in around them, and a lot of those small lots still run original clay and cast iron sewer laterals. After decades in the ground those old pipes crack at the joints, and tree roots work straight into the gaps. Some of the local groundwater also runs high on iron and manganese, which leaves scale and buildup inside the line that narrows it further. We have worked Cotati sewers since 2017, and the pattern is usually the same. A slow main-line backup turns out to be roots in an aging lateral, not anything you did wrong.

What that looks like on the job: A common Cotati job is a repeating main-line backup on an older lot off Old Redwood Highway. We drop a camera, find roots in a cracked clay lateral, and either spot-repair the bad section or replace the run out to the city main.
