The story

From a Career in the Trade to a Name on the Van

S · E · R Service · Excellence · Reliability

Twenty-plus years before the name went on a van

Jose Luis Serrano came into plumbing more than twenty years ago and discovered what keeps good tradespeople in the trade: he liked solving problems with his hands and his head at the same time. A decade of residential service taught him how homes fail and how homeowners feel about it. Five more years in commercial and industrial work, tenant improvements, gas piping, underground lines, occupied facilities where mistakes have audiences, taught him coordination, code discipline, and the habit of documenting everything.

2019: the leap

Leaving a steady W-2 for your own truck is frightening in the way all worthwhile leaps are. What pushed Luis was the chance to serve customers directly, without quotas or scripts, and to build something with his family's name on it for his family's future. SER carries the Serrano name, and the letters carry the standard: Service, Excellence, Reliability.

The philosophy, in one paragraph

A good plumber, in Luis's words, is not just someone who can install pipe: it is someone who diagnoses correctly, communicates clearly, recommends honestly, and stands behind the work. The expensive lesson of his early career was learning to slow down, verify, and inspect the whole system before starting repairs, and that lesson now greets every job before the tools do. It is why the camera comes out, why the findings get shown, and why nobody here will ever pressure you into replacing what a repair would fix.

Real Customer Example · From a verified Google review (Alexander J., May 2024)

Timely, responsible, authentic, excellent professional, friendly, and effective. Fixed my issue, advised me about future things, was honest, treated me like a human.

Our standard

What We Want You to Know About How We Work

01

Diagnosis first: instruments and cameras before conclusions, findings shown before quotes.

02

Written numbers before work, honored per the conditions we saw, with anything hidden shown and approved before it changes a thing.

03

Repair recommended when repair is right; replacement recommended when the evidence says so, and never before.

04

The trade's tools taken seriously: Luis will happily tell you why his RIDGID SeeSnake camera is the one tool he would keep if he could keep only one.

05

Clean exits, warranties in writing, and a phone that gets answered.

Our roots

Local, in the real sense

Luis grew up in Southeast LA County and has spent his working life serving it. Around a third of Ser Plumbing's customers prefer Spanish, and they get the owner himself, explaining options in the language the household actually decides in. The referral network that keeps the schedule full, family to family, property manager to property manager, is the community itself vouching.

The shop today

Deliberately small: Luis on the work, his wife helping run the office, an apprentice learning the trade the way Luis did, and trusted hands when jobs need them. Independently owned, no private-equity anything, and growing at exactly the pace that keeps the standard intact. The five-year plan is more of the same, done for more neighbors, with the same phone number Luis still answers.

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.

Lourdes K. · April 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.'
