Why electrical

Reliable Electrical System Upgrades and Solutions

A well-functioning electrical system is essential for maintaining the safety, efficiency, and comfort of a home. DECOMA Industries approaches each project with a commitment to providing modern, reliable solutions that meet the unique demands of every household. Whether it’s upgrading outdated wiring, installing new lighting systems, or ensuring compliance with the latest safety standards, the team takes a thorough approach to understanding the home’s current electrical infrastructure and making the necessary improvements. Homeowners benefit from improved energy efficiency, increased safety, and the ability to support modern technology and appliances with confidence.

Comprehensive Electrical System Enhancements and Upgrades

The process of enhancing a home’s electrical system begins with a detailed assessment, which helps identify areas that may need upgrading or repair. This can include rewiring, adding circuits for new appliances, or upgrading the electrical panel to handle increased loads. DECOMA’s skilled professionals prioritize safety and precision at every step, ensuring that all installations and repairs meet local building codes and industry standards. By integrating modern technology and materials, the electrical work performed enhances not only the functionality of the home but also its overall value and longevity.

What you get

Everything we deliver.

  • 01

    Pre-construction load study

    We document existing service, panel capacity, and circuit allocation before we cut a single wire — so the upgrade scope is a real number, not a guess.

  • 02

    Service & panel upgrades

    200A, 400A, and 800A residential and light-commercial panel replacements with utility coordination, permits, and inspection sign-off.

  • 03

    Code-compliant rough & finish

    Branch circuit rough-in, device installation, and fixture work to current CEC and Title 24 standards. We carry the inspections so the building opens on schedule.

  • 04

    EV charger & solar interconnect

    Level 2 and DC fast-charger installs, sub-panels for EV branch loads, and PV interconnect with the same crew that handles your main service.

  • 05

    As-built documentation

    Updated single-line diagram and circuit schedule at closeout, so the next time something changes you're not guessing what's behind the drywall.

How we run it

Scope to sign-off.

  1. 01

    Walk the building

    On-site assessment of the existing service, panels, and load. Photos of every panel, a load calc on every circuit.

  2. 02

    Scope & permit

    Itemized scope, a real number, and the permit package filed with the AHJ — Los Angeles County, City of LA, or your local building department.

  3. 03

    Self-perform the work

    DECOMA's in-house electricians do the install — no subbed-out trade. One PM, one schedule, one phone number.

  4. 04

    Inspect & hand off

    Final inspection signed, as-builts delivered, walk-through with your facility team. We answer the phone for warranty work.

FAQ

Common questions.

Are your electricians licensed and bonded?
Yes. DECOMA Industries holds CSLB Class A (General Engineering) and Class B (General Building) license #375508, with our electrical work performed by California C-10 licensed electricians on our team. We carry $2M general liability and workers' comp on every job.
Can you handle commercial electrical projects in the South Bay?
We've been doing commercial electrical work across Harbor City, Torrance, Manhattan Beach, Redondo Beach, Hermosa Beach, El Segundo, Palos Verdes, San Pedro, and the wider LA County since 1978 — multifamily, retail, office, light industrial, and adaptive reuse.
How long does a service or panel upgrade take?
A residential 200A upgrade is typically 1–2 days on-site after the permit clears, which usually takes 1–3 weeks with the utility. Commercial 800A and 1200A service replacements run 1–3 weeks on-site depending on switchgear lead times.
Do you coordinate with LADWP or Southern California Edison?
Yes — we handle the utility interconnect paperwork, schedule the disconnect/reconnect, and coordinate the meter set as part of the scope. You won't be on the phone with the utility.
Can you install EV chargers and solar at the same time?
Yes, and you should. Doing them together lets us right-size the service and sub-panel once instead of twice. We've installed Level 2 and DC fast-chargers on parking decks, fleet yards, and single-family homes from Palos Verdes to Inner City Arts in LA.
What about emergency electrical service?
We prioritize repeat clients' emergency calls — power outage, tripped main, smoking panel. Call (310) 418-0258 and we'll get a licensed electrician on-site same-day during business hours.
