Commercial Plumbing Services in Paramount, CA
Restaurants · Apartments · HOAs · Property Management | Documented Work, Tenant-Friendly Scheduling | CSLB #1051553 | Se Habla Español
Roughly a quarter of Ser Plumbing’s work is commercial, and it is commercial by design: restaurants that cannot lose a lunch rush, apartment buildings where one stack serves twelve kitchens, HOA communities balancing budgets and board approvals, and property managers who need a plumber that answers, documents, and does not create tenant drama.
Luis spent five years in commercial and industrial plumbing before founding the company, working in occupied facilities where coordination mattered as much as the wrench work. That is the standard here: real diagnostics, written scopes, photo and video documentation with every invoice, and scheduling built around your business hours instead of ours.
commercial by design
Who We Serve
Six kinds of property make up the commercial half of this business, and each one changes how the work is scheduled and documented.
What’s Covered
Drain and sewer service
Line cleaning, hydrojetting for grease-worked kitchen lines, camera inspections with footage your ownership can see, and sewer repairs planned around business operations. Hydrojetting → Sewer camera inspection →
Water heater service
Commercial-duty tank and tankless service, replacements scheduled to spare your peak hours, and straight capacity guidance when the current unit was never sized for the demand. Water heater service →
Leak detection and pipe repair
Evidence-first leak location across slab and multi-story construction, spot repairs, and repipe planning phased for occupied buildings.
Gas piping
Commercial kitchen lines, rooftop appliance runs, red-tag restorations, and pressure-tested repairs. Gas line services →
Fixture and restroom service
Commercial restroom banks, flush valves, sensor faucets, floor drains, and the fixture uptime a customer-facing business actually needs.
Water shutdown planning for occupied buildings
The repair is rarely the hard part in a working building; the shutdown is. We plan water-off windows around your operation, isolate at the riser instead of the building wherever valves allow, give your office the notice language tenants actually read, and stage the work so the dry window is as short as the plumbing physically permits. A well-run shutdown is the difference between maintenance and an incident report.
Medical offices and ambulance facilities
Among our ongoing commercial relationships are medical offices and ambulance service facilities, environments where cleanliness protocols, uptime, and documentation are not preferences but requirements. That standard travels with us to every commercial account.
Recurring maintenance
Scheduled service for properties that have learned emergencies cost more than prevention: descriptive scope, per-visit billing, no subscription theater.
Grease trap pumping and interceptor certification: not our lane, and we will point you to a specialist honestly
Backflow testing and certification: same straight answer
Large-scale new construction and tract work: we are a service and repair company by choice
Pricing & Terms
Commercial terms are built for decision-makers who need clarity before authorizing, and here is how it works:
Commercial pricing rewards clarity in both directions: defined scopes get flat-rate certainty, exploratory work is billed as exactly what it is, and nothing proceeds without written authorization from the person empowered to give it.
Payment terms for management and commercial accounts are arranged by prior agreement, and after-hours rates are always quoted before dispatch.
Why Ser Plumbing for Commercial
Commercial experience before the company existed
Five years of commercial and industrial work, tenant improvements to underground piping, before Ser Plumbing was founded. Occupied-facility habits run deep here.
Documentation as a default
Photos and video with the invoice, findings in writing, footage owners can review from anywhere. Property managers in our reviews name this exact habit as why they stay.
Vendor-file ready
Current license, insurance certificates, W-9: ready when your management company asks. Approval friction is not a service we offer.
Tenant-aware by training
Notice, respect, containment, and communication through your office. The plumbing should be the only thing tenants notice was fixed.
One accountable point of contact
The person who scoped your property answers for it. No rotating techs relearning your building every visit.

Leave Us a Google Review ↗Commercial FAQs
Nineteen straight answers to the questions we hear from owners, managers, and boards.
Ask us directly ↗Can you handle a multi-unit apartment building?
Do you work around business hours?
Deliberately. Restaurants get off-peak windows, retail gets early or late slots, and offices get the restroom back before the staff notices it was down. Disruption planning is part of the scope, not an accident.
What documentation do you provide?
Photos and video of the work, written findings, camera footage where lines were inspected, and invoices that describe what actually happened. Boards, owners, and adjusters all read the same clear file.
Are you set up for HOA and management vendor requirements?
Yes: current CSLB license, certificates of insurance, and W-9 ready on request. If your association or management company has a vendor packet, send it; this is routine for us.
Do you offer emergency commercial response?
Around the clock, subject to technician availability, with after-hours rates quoted before dispatch. A flooding restroom or failed water heater in an operating business gets emergency priority.
Can tenants schedule directly with you?
Only if your office wants it that way. Default is your channels, your notice rules, your approval chain; we adapt to portfolios, not the reverse.
