In Coronado, a backed up drain takes a little more planning, because everyone and everything has to come across the bridge. So the right equipment matters on the first trip. A small hand snake only reaches so far, and when the clog is past it, the drain stays right where it was. Equipment comes in tiers, and most people never hear about them until the wrong one shows up.
Here, the phone call comes before the drive. You'll be asked what's backing up, how often, and what kind of home it is, because an older cottage and a Shores tower drain very differently. Those answers decide what equipment comes across the bridge, the standard machine for a standard clog, the long cable for the deep ones, and the camera when the line keeps clogging and needs to be seen instead of guessed at.
When your drain needs more than a clearing, you'll get it explained in plain English, and the choice stays with you.
