Who we are

Ser Plumbing is a family-owned, owner-operated plumbing company based in Paramount, serving homeowners, landlords, and businesses across Southeast Los Angeles County, from Downey, Bellflower, and Lakewood to Compton, South Gate, Norwalk, and Long Beach. Jose Luis Serrano founded the company in 2019, drawing on more than two decades in residential, commercial, and industrial plumbing, on a simple idea: diagnose the problem correctly, explain it clearly, and let the customer decide.

Diagnosis first

Every job starts with a real inspection, not a sales script. We use sewer cameras, pressure testing, and manufacturer diagnostic procedures to find the root cause, then show you photos and video of what we found. Customers tell us the same story again and again: the last company guessed; Luis found it. Ser Plumbing is licensed, bonded, and insured (CSLB #1051553), and every estimate is in writing before any work begins.

One call, one plumber

Whatever brought you here- a water heater that quit overnight, a drain that keeps backing up, or a gas smell you should never ignore- one call gets you a real person who can actually fix it. Call (310) 953-3566 or schedule online, in English or in Spanish.

About The Owner

More Than Twenty Years in the Trade, One Name on the Van

Jose Luis Serrano started in plumbing more than twenty years ago and worked on residential, commercial, and industrial systems across Los Angeles County before founding Ser Plumbing in 2019. He founded Ser Plumbing to bring that experience home to Paramount and the surrounding communities. The name carries the Serrano family name and a standard: Service, Excellence, Reliability.

Ser Plumbing is still owner-operated by design. Luis diagnoses the work, quotes the work, and stands behind the work, with a small trusted team and his wife helping run the office. It is the opposite of the rotating-technician model, and it is why so much of the company's work comes from repeat customers, referrals, property managers, and HOA communities across Southeast LA County.

What Happens When You Call

From First Call to Finished Job, No Surprises

Five steps, every job, no exceptions. You always know what is happening, what it costs, and why — before anyone picks up a tool.

01

A real person answers, and emergencies move first

During business hours, your call is answered directly, usually by Luis himself. If the team is on a job, calls and messages are almost always returned the same business day. Active leaks, sewer backups, gas concerns, and no-hot-water calls are prioritized, with realistic arrival windows instead of promises that fall apart by afternoon.

02

Diagnosis before recommendations

We inspect before we quote. Depending on the problem, that can mean a sewer camera in the line, pressure testing, leak investigation, or manufacturer diagnostics on a water heater. The goal is the root cause, not the fastest thing to sell.

03

A plain-language explanation, with proof

You see what we see: photos, video, and a clear explanation of what failed and why. If a repair will hold, we say so. If replacement genuinely makes more sense, we explain the tradeoff and let you decide without pressure.

04

A written estimate before any work begins

Pricing is flat-rate for most residential and light commercial work, in writing, with options where they exist. No work starts without your authorization, and approved written estimates are honored unless hidden conditions change the scope, which we discuss with you first.

05

The work is done right, and the area is left clean

The same owner-led team that diagnosed the job performs it, to code, with shoe covers and drop cloths where appropriate. You get a walkthrough of the finished work, documentation and photos when applicable, and a written warranty that matches the type of repair.

Real Customer Example · From a verified Google review (Lourdes K., April 2024)

Another company looked at her shower and pitched major work at a price she called ridiculous. Ser Plumbing inspected it, found the real problem, and fixed the shower without overcharging. 'They are honest and hard working people,' she wrote afterward.

Why Choose Ser Plumbing

Seven Reasons Neighbors Keep Our Number Saved

Diagnosis first, recommendations second Owner-operated accountability Upfront, flat-rate pricing in writing 24/7 emergency response, framed truthfully
Ser Plumbing technician seated in the open service van Evidence, not guesswork Sewer cameras, drain locating, pressure testing, and manufacturer diagnostics.
Talk to the plumber (310) 953-3566
01

You talk to the plumber, not a call center

When you call Ser Plumbing, you reach the person responsible for your job. Luis answers most calls himself, typically returns messages the same business day, and stays your point of contact from diagnosis to walkthrough.

The big national brands route you through dispatch queues and rotating technicians who have never seen your house. Here, the plumber who quoted your water heater is the one standing in front of it.

02

Diagnosis first, recommendations second

We invest in the equipment that removes guesswork: sewer cameras, drain locating, pressure testing, and manufacturer diagnostics. You see photos and video of the actual problem before you approve anything.

That is the opposite of the replace-everything sales model. If a thermocouple fixes your water heater, you will not be sold a new unit. If a repair will only buy months, we tell you that too, with the evidence in hand.

Real Customer Example · From a verified Google review (Nathan D., property manager, January 2024)

His handyman attempted the same shower leak three times over a month and was ready to tear open the wrong wall. Ser Plumbing found the actual source and solved it in one visit at a reasonable cost. His verdict: 'Ser Plumbing will be first on our list.'

03

Owner-operated accountability

Ser Plumbing is built deliberately small: Luis, a small trusted team, and more than two decades of trade experience behind every decision. The person who gives you their word is the person who keeps it.

Repeat customers work with the same plumber who already knows their home's plumbing history, and first-time customers get the same person's word from estimate to final walkthrough.

04

A 5.0 Google rating we protect on every job

Our reviews come from homeowners, landlords, property managers, and HOA boards across Southeast LA County, and they are displayed live on this page, unedited.

A rating like that survives only one way: showing up when promised, charging what was quoted, and fixing the actual problem. We treat every job like the review is already being written.

05

Upfront, flat-rate pricing in writing

Most residential and light commercial work is quoted flat-rate before it starts. You approve a written number, not an hourly meter, and approved estimates are honored unless hidden conditions genuinely change the scope.

No surprise line items at the end, no phone-quote games, no pressure tactics. Just the price, the options, and your decision.

Real Customer Example · From a verified Google review (Alex F., September 2023)

Alex has hired Luis for everything from a small leak to a full-scale repipe: 'He's always fair and doesn't try to upsell you on things you don't need.' By his own comparison, a large nationwide company could probably do the job too, 'but you'll get better results, better service and probably a better price too from Luis, who owns and takes pride in his company.'

06

24/7 emergency response, framed truthfully

Burst pipe at 2 AM, sewage backing up on a holiday, a gas smell you cannot locate: emergency calls are answered around the clock and prioritized by severity, subject to technician availability.

We would rather quote you a realistic arrival window than make a promise no one can keep. After-hours rates are always stated before dispatch, never sprung on you afterward.

07

Bilingual service with local roots

Luis grew up in Southeast LA County and has spent his career serving it. Around a third of our customers prefer Spanish, and they get the same clear explanations, written estimates, and follow-up as every other customer, directly from the owner.

For multi-generational households making a repipe or water heater decision together, having one plumber who can walk the whole family through it, in either language, matters more than any brochure.

Before You Hire

What to Ask Any Plumber Before You Hire Them

Use these seven questions with any plumbing company you call, including us. They will save you money and grief no matter who does the work.

01

Are you licensed with the CSLB, and what is the license number?

Verify it for free at cslb.ca.gov. Ours is #1051553.

02

Are you bonded and insured, and can you show proof?

Unlicensed operators put the liability for accidents and damage on you, the homeowner.

03

Who actually shows up: the person quoting me, or a different crew?

Ask whether the diagnosing plumber performs the work.

04

Will I get the estimate in writing before work begins?

Verbal ballparks grow. Written numbers do not.

05

What happens if I decline the work?

You should owe the stated service or diagnostic fee, never a penalty or a pressure pitch.

06

What is the workmanship warranty, separate from the parts warranty?

Get the labor coverage in writing on the invoice.

07

Have you worked on homes like mine?

SE LA County housing runs from pre-war bungalows with galvanized pipe to slab-era tract homes. Era experience matters.

Ask us all seven. We will answer every one before you commit to anything, and the answers will be in writing.

ANSWERS
A Few FAQs

Frequently Asked Questions

Straight answers to the questions we hear on the phone every week.

The standard service call is $89 for residential customers and $125 for commercial properties, within our regular service area during normal business hours. It covers travel, a visual inspection, discussion of findings, and a written estimate. After-hours and emergency visits carry different rates, always quoted before we dispatch.

Yes, on most replacement and installation projects: water heaters, repipes, softeners, sewer replacements, and similar work. Troubleshooting visits, leak detection, and camera inspections carry a diagnostic fee starting at $125, and that fee is often credited toward the repair when you approve the work.

Emergency calls are answered around the clock, every day of the year, and dispatched by severity, subject to technician availability. Burst pipes, sewer backups, gas concerns, and total water loss move to the front of the line. After-hours rates are stated up front before anyone is dispatched.

Yes. Ser Plumbing Inc holds CSLB license #1051553 and is licensed, bonded, and insured. You can verify the license in about a minute at cslb.ca.gov, and we encourage you to check any contractor you are considering, including us.

Often it can be repaired. Many no-hot-water calls trace to a failed thermocouple, gas control valve, heating element, or sensor, which costs far less than a new unit. We diagnose first and give you both numbers, the repair and the replacement, with a straight read on how much life the repair buys. If the tank itself is leaking, replacement is usually the right call, and we can typically do it the same day at the regular price.

A drain that keeps backing up usually means the blockage sits deeper in the line: grease buildup, root intrusion, a bellied section, or a broken pipe that snaking only pokes through. A camera inspection shows the actual cause on video, and from there the fix might be hydrojetting, a spot repair, or nothing more than a proper cleaning. You see the footage before you decide anything.

Every week. Much of Southeast LA County was built between the 1940s and the 1970s, which means original galvanized supply lines reaching the end of their life and copper embedded in slabs now prone to pinhole leaks. We repair, reroute, and repipe these systems constantly, and we will tell you plainly whether a spot fix or a repipe serves you better.

Yes. Roughly a third of our work is light commercial: restaurants, retail, medical offices, apartment buildings, condominium communities, and property-management accounts across SE LA County. Property managers get documentation, photos, and direct communication with tenants coordinated through your office.

Yes, for qualifying projects. Consumer financing is available through our booking platform, with terms subject to lender approval. It is most commonly used for repipes, sewer replacements, and tankless conversions. Ask when you schedule.

Completamente. Luis is fully bilingual, and explanations, estimates, and follow-up are available in Spanish or English from the first call to the final walkthrough. Around a third of our customers prefer Spanish, and many of our reviews are written in it.

We stand behind our workmanship with a written labor warranty that varies by service type, typically 90 days to one year, stated on your estimate and invoice. Manufacturer warranties on equipment pass through per the manufacturer's terms, and we help with the paperwork. Drain snaking carries no warranty because the condition of an old drain line is outside anyone's control, and we would rather tell you that up front.

If water is flowing where it should not, close the fixture shutoff or the main shutoff valve, usually near the front hose bib or the water meter. Avoid using affected drains or fixtures. If you smell gas, leave the home, call SoCalGas from outside, and then call us. We will walk you through all of it on the phone.
