Are you licensed and insured in California?

Yes. We hold a CSLB C-36 Plumbing Contractor license and carry full general liability and workers compensation insurance. Our license number is on every truck, invoice and page of this site.

What is your service area?

Our home base is 1010 W 19th St in National City. From there we cover the South Bay (Chula Vista, Bonita, Imperial Beach, Coronado), the City of San Diego, East County (Lemon Grove, Spring Valley, La Mesa, El Cajon, Santee, Lakeside and the backcountry CDPs) and South Riverside County (Menifee, Lake Elsinore, Perris, Hemet and the Pass corridor).

Do you charge for estimates?

Estimates for planned work — repipes, sewer replacements, water heater swaps, remodels — are always free and written on the spot. Diagnostic visits for a specific active problem carry a flat trip charge that is waived if you approve the repair.

How much does a typical repair cost?

Every job is quoted flat-rate before we start. Small residential repairs — a leaky angle stop, a broken flapper, a garbage disposal swap — typically fall in the $150–$450 range. Bigger jobs (drain jetting, water heater replacement, sewer trenchless liner, whole-house repipe) are quoted individually so you know the total before we open a wall.

How the job goes

On-site walkthrough

For property managers and new commercial clients, we walk the property, document every fixture and shutoff, and hand you a maintenance schedule you can share with tenants and inspectors.

Scheduled maintenance

Hydro jetting on restaurant kitchen lines (quarterly or semi-annual). Grease trap pumping and reporting. Backflow prevention device annual testing. Water heater flushing. All fixed-price, calendared, no missed intervals.

24/7 emergency dispatch

Property managers get a dedicated escalation number. Emergency response prioritized ahead of residential calls for commercial contract accounts.

Buildouts and remodels

Restaurant and retail buildouts: permit, rough-in, finish, sign-off. We coordinate with your GC, architect and health department.

Commercial we handle constantly in the South Bay

Restaurants along Highland Ave and E 8th Street. Grease traps, kitchen drain jetting, hand-sink and dishwasher lines, three-compartment sink drains, floor drains under prep tables, ice machine drops. We run overnight so we do not interrupt service.

Mile of Cars dealerships. Employee restrooms, showroom bathrooms, service bay floor drains and oil-water separators, wash-bay plumbing.

Marina District and downtown National City retail. Small-suite restrooms, shared walls between tenants, buildouts for new tenants.

Tidelands industrial corridor. Warehouse restrooms, process water lines, industrial floor drains, backflow prevention on landscape and process water.

Multi-family and apartment complexes. Water heater replacement fleets, unit-by-unit fixture repair, common-area plumbing, main-line drain jetting.

HOAs and condominium associations. Shared-line responsibilities, common-area water features, community pool plumbing.

What sets commercial apart

Commercial plumbing runs on:

Health department requirements (three-compartment sinks, hand-sink placement, backflow prevention)
Code compliance for public-use fixtures (ADA, low-flow, water heater delivery temperatures)
Business-continuity thinking (schedule work at 2 AM, not lunch service)
Documented maintenance records that survive tenant turnover and inspection visits

We think that way from day one on every commercial account.

Grease trap and drain program

Restaurants on our maintenance program get:

Grease trap pumping on the interval required by City of National City (typically 90 days for busy kitchens)
Kitchen drain hydro jetting on a 90 or 180 day cycle depending on volume
Written pumping receipts and inspection records for FOG (fats/oils/grease) compliance
Emergency response priority when a clog does happen

No more scrambling for a plumber on a Friday night when a drain backs up during dinner service.

Backflow prevention

Annual testing of RP and DCVA assemblies is required by Sweetwater Authority and California Water for landscape irrigation and process water on commercial properties. We test, tag, and file directly with the water district.

Buildouts and TI work

Tenant improvement plumbing: rough-in, finish, permit, health department sign-off on restaurant TIs. We work with the GC of your choice or run it directly.

Our shop is at 1010 W 19th St, three minutes from I-5 and five minutes from National City Blvd. Commercial contract clients get a dedicated account manager, a documented maintenance calendar, and 24/7 escalation. Call (831) 290-4327 and a live dispatcher will confirm a real ETA before you hang up — no call center runaround, no "we'll get back to you."

What affects the price

We do not post fake "starting at" prices. Every job is quoted flat-rate on-site. Here is what moves the number up or down:

Scheduled maintenance contract vs. one-time visit

Number of fixtures / units under management

Grease trap size and pumping frequency

Backflow prevention count and jurisdiction

Emergency call priority tier

Why South Bay Pro Plumbing for commercial

Commercial is one of the core reasons customers call our shop — not a side service we occasionally take. Over 16+ years running crews out of National City, we have built a written playbook for commercial in the South Bay housing stock: what we open, how we test, which parts we replace by default, and which materials perform on Sweetwater's water. Every job is quoted flat-rate on-site before we start, permitted with the applicable jurisdiction where required, and warrantied in writing on the invoice.

16+ years in the South Bay

Not a franchise. Same crew, same standards, same license number on every truck (CSLB C-36 #1099432).

428 verified 5-star reviews

Real work for South Bay and East County homeowners, restaurants, and property managers.

Camera-verified where it matters

Every sewer diagnosis and every repipe pre-check gets camera footage handed to you.

Written estimates, no bait pricing

Flat-rate quote in your hand before we open a wall. Diagnostic fee credited to the job if you approve same-day.

Permits pulled and closed

We handle City of National City, San Diego County, City of San Diego, and Riverside County permitting.

45-minute emergency response across the South Bay

Live dispatch, 24/7. No answering services and no "we'll get back to you."

Commercial across the South Bay & greater San Diego

We dispatch commercial crews from 1010 W 19th St, National City out to every city and CDP inside our service map. Tier-1 South Bay response is our fastest — Chula Vista, Bonita, Imperial Beach, Coronado, and Lemon Grove. Central San Diego, East County (La Mesa, El Cajon, Santee, Spring Valley) and South Riverside (Menifee, Lake Elsinore, Perris, Hemet) round out the reach.

Not sure whether we cover your address? Call (831) 290-4327 — we quote a realistic ETA before you book, and mark extended-service cities on their own pages.

Frequently Asked Questions

Yes — a live dispatcher, not a recording. Nights, weekends and holidays included. Our target is a 45-minute on-site response anywhere in the South Bay for true emergencies (flooding, sewage backup, gas smell, no water).
