Commercial Electrical Upgrades in Brea, CA
Commercial electrical upgrades in Brea (Brea Hills). C-10 #1120441. Call (657) 239-6331.
Quick answer
Do you rewire suites and small commercial in Brea?
Yes when the branch wiring itself is the problem (aluminum, ungrounded, cloth), not only the panel. We cover Brea 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.
Electrical Upgrades in Brea
Commercial capacity upgrades for Brea suites mean feeders, distribution, and branch circuits sized for real tenant load. We pull city permits when required and coordinate SCE when the service moves. Downtime is written into the quote so opening hours are not a surprise. Call (657) 239-6331 with the suite address and what loads you cannot lose.

Brea issues we see with electrical upgrades
- Overloaded 100A services: dryer, AC, and kitchen trip the main when they run together
- Federal Pacific, Zinsco, or Pushmatic panels that still turn up here: 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 a bathroom remodel
About Brea
First Electric is a licensed C-10 shop based in La Mirada (C-10 #1120441). We cover homes and small commercial suites across Brea: Downtown Brea, East Brea, and West Brea.
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 and pull the permit. 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 Brea 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.
Yes. California C-10 electrical contractor license #1120441, bonded and insured. You can verify our license status through the CSLB (details on our license page).
Service Questions
Age alone is not the rule, condition is. Many 60-70 year old Brea homes still have original cloth, knob-and-tube, ungrounded circuits, or overloaded panels. If circuits are brittle, ungrounded, aluminum branch wire, or failing inspection/insurance review, a partial or full rewire is often the right long-term fix.
Sometimes. Attic and crawlspace fishing can replace many runs with limited patching. Fully concealed damage, plaster lath, or slab homes may need more opening. We scope the least-invasive path that still passes inspection.
Pricing Questions
Commercial upgrade and TI pricing depends on infrastructure and equipment load. Every job is different. We provide a custom quote after we see your site. Typical commercial electrical projects often start around $2,832 in labor (8 hours at our standard rate) before materials, permits, and scope; there is no one-size-fits-all maximum.
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 Brea from our La Mirada shop nearby. People call for everyday repairs, panel work when the service is maxed out, and emergencies when something is sparking or half the house is dark. Call (657) 239-6331; a real person answers.
