How the scorecards are built

The scorecards use public Google data on the date shown. Rating is the live star average, and review volume is how many customers have rated the company, compared with other San Antonio plumbers offering drain cleaning. Confidence weighs the rating by that volume, and recency shows how recently reviews are still arriving.

What shapes the price of drain cleaning

Drain cleaning is priced by the location of the clog, how easy the line is to reach, whether a camera inspection is needed and whether the call is after hours. Roto-Rooter’s site says it adds no extra charge for plumbing or drain service on holidays, nights and weekends, so ask every company how it handles after-hours calls.

Who covers which part of San Antonio

Roto-Rooter and City Base work from addresses on W Commerce St and Rockwood Ct, while Juan’s and CoverAll list no street address. Juan’s site names communities including Converse, Schertz, Helotes, Alamo Heights and Boerne, and a Roto-Rooter reviewer mentions a visit in the Castroville and Medina area. Looking for drain cleaning near me? Each listing shows a phone number so you can check coverage for your address.

What to ask before a plumber clears your drain

  • Is there a call-out fee, and does it apply toward the repair?
  • Will you use a camera to find the cause of the clog?
  • Is the price quoted before work starts, in writing?
  • Is there an extra charge for nights, weekends or holidays?
  • How do you clear a main line versus a single fixture drain?
  • Is the work guaranteed if the clog returns?

Frequently asked questions

Do San Antonio plumbers charge extra for after-hours drain cleaning?

It varies. Roto-Rooter’s site says there is no hidden or extra charge for plumbing or drain service on holidays, nights and weekends. Ask any other company about its after-hours policy before you book.

Which of these companies uses a sewer camera?

City Base Plumbing’s site mentions finding the root of a drain problem with sewer cameras. Ask the other companies whether a camera is used for your job.

Is drain cleaning the same as sewer line repair?

No. Drain cleaning clears a blockage, while sewer line repair or replacement fixes a damaged pipe. City Base and Juan’s list both on their sites, and reviewers of both describe sewer line work. A camera inspection helps tell which one you need.

Do these plumbers work outside San Antonio?

Juan’s Plumbing Services lists communities including Converse, Schertz, Helotes and Boerne, CoverAll serves San Antonio and surrounding areas, and a Roto-Rooter reviewer describes a technician visiting the Castroville and Medina area. Confirm coverage for your address.

Our pick to call first

Roto-Rooter Plumbing & Water Cleanup is the safe default on proven volume, and City Base Plumbing is worth a call if you want a camera inspection. Whoever you choose, get the estimate in writing before the work begins.
