Commercial Electrical Upgrades in Fullerton, CA
Commercial electrical upgrades in Fullerton (Sunset Lane). C-10 #1120441. Call (657) 239-6331.
Quick answer
Do you rewire suites and small commercial in Fullerton?
Yes when the branch wiring itself is the problem (aluminum, ungrounded, cloth), not only the panel. We cover Fullerton from our La Mirada shop. We scope panel-only versus rewire-heavy after a walkthrough. Every job is different. We provide a custom quote after we see your site. Typical whole-home rewire or major upgrade projects often start around $9,913 in labor (28 hours at our standard rate) before materials, permits, and scope; there is no one-size-fits-all maximum. Call (657) 239-6331.

TI densification and HVAC adds often outgrow the original suite feed. Building Division permits and SCE coordination apply when the service moves.

Fullerton issues we see with electrical upgrades
- Overloaded 100A services near Downtown and Hillcrest: kitchen and AC trip the main together
- Federal Pacific, Zinsco, or Pushmatic panels that still turn up in mid-century houses: warm breakers or a main that will not stay reset
- Aluminum or ungrounded branch circuits: two-prong rooms that fail a buyer inspection
- Shared neutrals and kitchens remodeled without a service upgrade: lights flicker when the laundry starts
- Dead outlets and GFCI that will not hold after a storm or bathroom remodel
About Fullerton
First Electric is a licensed C-10 shop based in La Mirada (C-10 #1120441). We cover homes and small commercial suites across Fullerton: Downtown, Sunset Lane, Hillcrest Park, Amerige Heights, and the Commonwealth corridor.
People call when something stopped working: a dead receptacle, a breaker that will not hold, half a house dark, or a panel that feels warm. We fix that first. When the service is maxed out (no spare slots, unsafe gear, or load that will not support an ADU or Level 2 charger), we plan the upgrade honestly, pull the permit, and coordinate SCE when the meter moves. Fire or life-safety emergency? Call 911 first, then us.
How a commercial upgrade usually runs
Walk the suite
We look at the panel, accessible wiring, equipment loads, and problem areas. You get an honest scope: targeted vs broader upgrade.
Written plan and quote
Every job is different. We provide a custom quote after we see your site. Includes outage windows, sequencing, and what other trades need to know.
Permit and protect
We pull permits when required, protect finished areas, and stage work so inspection milestones are clear.
Install, test, inspect
New circuits, devices, and protections as scoped. Test under load when possible, then city sign-off when required.
Timeline
Targeted upgrades may finish in a day or two. Broader suite rewires run longer and often need off-hours blocks. We set expectations after the walkthrough.
Why businesses trust us with upgrades
Right-size the scope
Smallest correct fix first. Full gut only when the distribution system warrants it.
Operations-aware scheduling
Off-hours and phased cutovers when the work allows so customers and staff are not stranded.

Frequently Asked Questions About Electrical Upgrades
Process Questions
We do not give blind estimates over the phone. After we understand your Fullerton project and, when needed, visit the site, we provide a custom written quote with scope and pricing spelled out. Call (657) 239-6331 to start.
It depends on the lease. Some landlords deliver a vanilla shell allowance; others push TI electrical to the tenant. We work with tenants, GCs, and property managers in Fullerton and price only the electrical scope you own under the agreement.
Service Questions
TI electrical typically covers demo of old circuits, new lighting and controls, dedicated receptacles, panel or subpanel changes, low-voltage pathways when scoped, and permit/inspection. Exact inclusions follow your lease exhibit and architectural plans. We quote from drawings and a site walk.
Yes, new kitchens, medical gear, CNC, EV fleets, and HVAC often need feeders, panels, or 3-phase work. We load-calculate and design additions that pass inspection without overselling gear.
Yes. Downtown and Commonwealth corridor shops and offices call us for commercial electrical panels and service changes. We size the panel for real load, pull Fullerton permits, and plan cutover. We do not install utility transformers or industrial switchgear.
Pricing Questions
Rewire pricing depends on access (attic/crawlspace vs walls open), knob-and-tube or aluminum remediation, panel condition, and finish repairs. A ~2000 sq ft home is not a fixed package price. Every job is different. We provide a custom quote after we see your site. Typical whole-home rewire or major upgrade projects often start around $9,913 in labor (28 hours at our standard rate) before materials, permits, and scope; there is no one-size-fits-all maximum.
Location Questions
Yes. We serve Fullerton homeowners and businesses from nearby La Mirada: repairs and inspections first, then panel upgrades, rewires, and commercial work downtown and along Commonwealth. C-10 #1120441; call (657) 239-6331.
