The license-checked way to hire an Oceanside plumber
Oceanside plumbers, ranked and license-checked — we rank each from public Google review data and check it against CSLB license records, dated and published: exactly how this list works →
Coastal SD Pros is a data-first registry, not a media site. Every company is ranked by public Google review volume, each checked against the state license record, with local cost data and a published bar you can read. No pay-to-rank. We flag delistings instead of hiding them.

Check any North County plumber's CSLB license in 30 seconds
Before you let anyone into your home, confirm the state record: is the license active, does it carry a C-36 plumbing classification, is the bond on file, and is workers' comp in force? We'll walk you through reading the exact CSLB detail page — the same records this registry is built on.

A short, plain-language guide to the Check-A-License detail page — status, classifications, bond, and workers' comp — with the exact fields to look at.
What plumbing typically costs in Oceanside
Typical price ranges for common jobs, to help you sanity-check a quote. These are general estimates — not quotes — and every company prices its own work.
Ranges are general estimates for North County San Diego and can vary widely with the specific job, parts, accessibility, permits, and whether it's an after-hours emergency. Always get a written, itemized quote before work begins. Coastal SD Pros does not set or guarantee any company's pricing.
A transparent, repeatable method
No pay-to-rank and no invented scores — the order is driven entirely by public data, public records, and a stated rule.
Who qualifies
Plumbing companies serving Oceanside with a public Google rating of 4.5★+, at least 25 reviews, and an active CSLB license with a plumbing classification (checked July 6, 2026). The full bar →
How they're ordered
By number of Google reviews — the clearest public signal of sustained local demand and track record. Review data was collected June 20, 2026. How the order works →
How it stays honest
Every entry is dated and attributed to Google, and every license line is drawn from the CSLB record. Any sponsored placement is labelled and kept out of this ranking. What gets a company delisted →
Are you a North County plumber?
Your CSLB record is already public — this is exactly how homeowners find and vet you here: a dated Google-review ranking, a license check, and a published method. The directory ranks companies from public data, so you can't pay to move up the ranking.
Want the same record-backed local-authority system under your own brand? Coastal SD Pros is built by Roscoe Site Pro, which builds these systems for contractors. Start with the free diagnostic — no signup, no call required.
Want to be a Featured Partner on this directory? Featured placement is a clearly-labelled sponsorship, kept separate from the ranked list — it never buys a higher ranking. No company is currently sponsored. Ask about featuring at (888) 636-3939.

Read the data behind the registry
Three guides built from the same public records and dated pulls — no generic blog fluff, just what the data says.
Questions people ask first
Coastal SD Pros is record-backed and dated. Every listing is ranked from public Google review data (collected June 20, 2026) and checked against CSLB license records (checked July 6, 2026), against a published rule — 4.5★ or higher, at least 25 reviews, and an active CSLB license with a plumbing classification, ordered by review volume. The full methodology is published here → We flag delistings rather than quietly deleting them.
Companies are ordered by the number of public Google reviews, among plumbers serving Oceanside that have a Google rating of 4.5 or higher, at least 25 reviews, and an active CSLB license with a plumbing classification. Review data was collected on June 20, 2026; license records were checked July 6, 2026, and either may have changed since. It reflects review volume, not our judgment of quality, and it is not an endorsement. Our full methodology is published here →
As a general guide, common jobs typically run: drain cleaning $150–$450; water heater replacement $1,500–$3,500; leak detection and repair $250–$1,000 or more; toilet repair or replacement $150–$600. After-hours and emergency calls cost more. These are typical ranges only — each company sets its own pricing, so get a written quote before work begins.
Coastal SD Pros is an independent registry built by Roscoe Site Pro. If you want the same record-backed local-authority system under your own contractor brand, Roscoe Site Pro publishes a free Contractor Lead Leak Map diagnostic and a Contractor Growth Hub. Featured-partner placement on this directory is separate, always labelled as sponsored, and none is current.
No. Coastal SD Pros is an independent local registry. We list plumbing companies that serve the Oceanside area from public data and public records. We do not perform plumbing work and are not affiliated with the businesses listed.
