How we run it

Scope to sign-off.

  1. 01

  3. 03

    Self-perform the work

    DECOMA's in-house plumbers do the install. One PM, one phone number, one crew that keeps your tenants out of the elevator.

FAQ

Common questions.

Are you licensed for commercial plumbing in Los Angeles County?
Yes. DECOMA holds CSLB Class A and B licenses (#375508) with C-36 plumbing trade work performed by our in-house licensed plumbers. We're permitted and bonded for commercial work across LA County and every South Bay city.
Can you handle a plumbing emergency same-day?
For repeat commercial clients in the South Bay — usually yes, within 2–4 hours during business hours. Call (310) 418-0258. We prioritize active leaks, sewer backups, and gas-line emergencies.
Do you do repipes on occupied multifamily buildings?
Yes. We phase the work unit-by-unit so tenants stay in place, schedule water shutoffs in 4–6 hour windows, and coordinate notice with property management. Copper, PEX, and CPVC depending on the building and budget.
What's involved in a grease trap install or certification?
Sizing per LA County health code, installation with required cleanout and venting, certification paperwork to the city. For repeat restaurant clients we handle the annual maintenance, pumping coordination, and inspection sign-offs.
Do you offer service contracts for plumbing maintenance?
Yes. We have ongoing maintenance contracts on multifamily, retail, and restaurant clients across Manhattan Beach, Redondo Beach, Torrance, and Harbor City. Quarterly walk-through plus priority response.
How do you handle gas-line work?
Gas-line work requires SoCalGas coordination, a city permit, and a pressure-test sign-off. We pull the permit, do the install, schedule the gas company for the meter check, and don't leave until the line is live and the inspection is closed.
