5 Best Plumbers in Riverside (2026)

How the scorecards work

Every number on this page comes from public Google data on the date shown, not from opinion or payment. Rating is the live Google star average. Review volume is how many customers have rated the company, compared with other local plumbers. Confidence weighs the rating by that volume, so a 4.8 from hundreds of customers counts for more than the same score from a few. Recency shows how recently people still leave reviews. No business can pay to change these numbers.

What do plumbers charge in Riverside?

Plumbing prices swing with the job: a clogged drain costs far less than a slab leak or a full repipe, and after-hours calls often carry a premium. Many companies charge a service fee or a flat rate by task. None of the companies here publishes a price list on its Google profile, so we show no price table. Ask for a written, itemized estimate and whether the visit fee is credited toward the repair.
