J-Masters Electric has been handling residential and commercial electrical work in Northridge since 1990. That is 36 years of showing up, doing the job right, and earning the next call. Whether you own a home, manage a rental portfolio, or run a commercial property in Los Angeles County, we are the local electricians neighbors have trusted for more than three decades. Same-day electrical service available for urgent needs. Honest quotes. Code-compliant work. Reliable power.
Every home's wiring tells a different story, and after 36 years in Northridge, we have read a lot of them. The business started as a one-truck operation focused on residential repairs in the neighborhood. Over time, the work expanded to cover commercial properties, landlord accounts, and the full range of electrical upgrades that homeowners and property managers need today. The crew grew. The scope grew. The commitment to doing things right stayed exactly the same.
Being local means we are easy to reach and easy to work with. When you call, you are talking to someone who knows Northridge, knows the housing stock in the San Fernando Valley, and can give you a straight answer about what the job involves and what it will cost.
We serve homeowners, landlords, property managers, and commercial clients throughout the area. The kind of electrical work neighbors pass along by word of mouth is what we have built this business on, and that is still how most of our calls come in.
A properly wired home is a safer home, and keeping that wiring in good shape is something every property owner eventually faces. We handle the full range of everyday electrical work, from a single dead outlet to a complete panel replacement. Here is a closer look at what that covers.
Dead outlets, flickering lights, tripping breakers, and wiring faults do not fix themselves. We diagnose the source of the problem before we touch anything, so the repair actually solves the issue rather than masking it. That includes GFCI and AFCI protection checks, arc-fault and ground-fault breaker testing, and full troubleshooting and diagnostics for anything unusual happening with your electrical system.
Older panels were not built for today's electrical loads. If you are running out of breaker slots, dealing with a fuse box, or planning a major addition or appliance upgrade, a panel replacement or 200-amp service upgrade is often the right move. We handle load calculations, subpanel installation, and service-entrance upgrades. We stand behind every circuit we touch.
New outlet installation, GFCI outlet replacement, switch repair, and dedicated circuits for dryers, refrigerators, and other appliances are everyday requests we handle quickly and cleanly. Code-compliant wiring on every job, no shortcuts.
Northridge has a lot of homes built in the mid-twentieth century, and some of them still have knob-and-tube wiring or aluminum branch-circuit wiring that needs attention. Whole-home rewiring, knob-and-tube replacement, and aluminum-wiring remediation are jobs we have done many times. We know how to work through an occupied home efficiently and leave the space clean when we are done.
Call and we will handle the lights, outlets, and panel.
From older homes to new commercial builds, lighting is one of the most visible parts of any electrical project. We install recessed lighting, LED retrofits, exterior and landscape lighting, security lighting, and motion-sensor fixtures. If you want better light in a kitchen, a lit-up driveway, or security lighting around a commercial property, we can wire it properly and make it look clean.
Ceiling fan installation is one of our most common residential calls. We handle the wiring, the mounting, and the switch, whether it is a straightforward swap or a new installation where no fan existed before.
We show up ready to work.
When the power goes out, or when you are planning for the day it might, having the right electrical infrastructure already in place makes a real difference. Southern California homeowners and businesses have good reasons to think ahead on all three of these.
California leads the country in EV adoption, and Northridge homeowners are charging at home in growing numbers. We install Level 2 EV charger circuits, run the dedicated circuit from your panel, and confirm that your panel has the capacity to handle the load. If an upgrade is needed first, we handle that too.
Wildfire season and grid reliability are real concerns in the San Fernando Valley. A properly wired transfer switch lets you connect a backup generator safely, without back-feeding the grid and without running extension cords through your house. We install transfer switches, wire generator hookups, and connect standby generators to your service entrance. We show up on time and ready to wire.
A single voltage event can damage appliances, electronics, and HVAC equipment throughout a home. Whole-house surge protection, installed at the panel with proper grounding and bonding, is one of the most cost-effective ways to protect everything plugged into your home. We install surge protection devices that cover the entire system, not just a single strip.
Pick the date. We do the wiring. We clean up after.
Landlords, property managers, buyers, and sellers all have reasons to want a thorough electrical inspection. We inspect homes, rental units, and commercial properties, checking panel condition, outlet grounding, GFCI and AFCI protection, smoke detector wiring, and hardwired CO detector installation. We document what we find and walk you through what needs attention.
For additions, remodels, and tenant improvements, we handle electrical rough-in and permit-ready installs. All work is performed by licensed electricians and meets current California electrical code. If you are preparing a property for sale, bringing a rental up to code, or adding square footage, we can get the electrical side done right the first time. Call today and we will set the appointment.
Office buildings, retail spaces, and light commercial properties have electrical needs that go beyond the typical homeowner call. We handle commercial electrical repair and installation, including panel work, circuit additions, lighting upgrades, and electrical rough-in for tenant improvements.
For landlords and property managers, we understand that scheduling and reliability matter as much as the work itself. We coordinate around tenant schedules, keep disruption to a minimum, and communicate clearly about what the job involves before we start. The kind of reliability that keeps a property manager calling the same electrician year after year is what we aim for on every commercial account.
No one wants to be surprised by a bill that looks nothing like the estimate. We provide clear pricing before work begins. If something unexpected comes up mid-job, we explain it before we proceed. You know what you are paying for.
Same-day service is available for urgent situations. For planned work, scheduling is straightforward: call for a quote, pick a time that works, and we show up. No complicated process, no waiting weeks for a callback.

How do I know if my panel needs to be upgraded?
A few signs point clearly in that direction: a panel still running on 100 amps or less, breakers that trip under normal household loads, a fuse box instead of circuit breakers, or visible signs of heat damage or corrosion inside the panel. If you are planning to add an EV charger, a battery backup system, or a major appliance, a load calculation will tell you whether the existing panel has the capacity. Call us and we will walk through what you have and what makes sense.
What causes a breaker to trip repeatedly?
Repeated tripping usually means one of three things: the circuit is carrying more load than it was designed for, there is a wiring fault somewhere on the circuit, or the breaker itself is worn and no longer holding properly. Running a microwave, space heater, or other high-draw appliance on a shared circuit is a common cause. A dedicated circuit sized for that load is often the right fix. We diagnose the actual cause before recommending anything.
Is the work permitted and inspected?
Yes. Any work that requires a permit under Los Angeles County or city code gets one. We handle the permit application and coordinate the inspection so you have a clean record on file. That matters when you sell the property or make an insurance claim, and it protects you from having unpermitted work flagged during escrow.
Same-Day and Emergency Availability
We offer same-day electrical service throughout Northridge and the San Fernando Valley, and we take after-hours calls when the situation cannot wait. Call early for the best chance at a same-day appointment.
What does flickering or dimming lights usually mean?
Occasional dimming when a large appliance starts up can be normal, but lights that flicker consistently or dim without an obvious cause are worth having looked at. Common causes include a loose connection at the fixture, a failing breaker, a shared circuit that is overloaded, or a neutral wire issue. In older homes, it can also point to wiring that has deteriorated over time. We trace the problem to the source rather than guessing.
Is the wiring in an older Northridge home safe?
It depends on what is there and what condition it is in. Homes built before 1970 in this area sometimes still have knob-and-tube wiring or aluminum branch-circuit wiring. Both present real safety concerns and can affect homeowners insurance coverage. An electrical safety inspection gives you an honest picture of what the system looks like and what, if anything, needs attention. We explain what we find and what it would take to correct it.
What do I need for a Level 2 EV charger at home?
A Level 2 charger runs on a dedicated 240V circuit, typically 40 to 50 amps, with the outlet or hardwired connection located in your garage or at your driveway. We assess your panel to confirm it has the capacity to carry the new circuit, run the wiring, and install the outlet or connection point. If the panel needs an upgrade to support the added load, we handle that as part of the same project. We also pull the permit so the installation is on record with the county.
Work Performed by Licensed Electricians
Every job is handled by licensed electricians who know Los Angeles County permit requirements and California electrical code. We pull permits when the work requires them and coordinate inspections so your record is clean.
Do I need to be home while the work is being done?
For most jobs, yes. We need access to the panel, the areas where we are working, and the ability to ask questions or confirm scope if something unexpected comes up. For larger projects that run across multiple days, we can work out the details with you on scheduling. We try to keep disruption to a minimum and let you know what to expect before we start.
How do estimates and pricing work?
We discuss the job over the phone first to get a sense of the scope, then give you a straight quote before any work begins. If something unexpected comes up once we are into the job, we explain it and get your approval before proceeding. You know what you are paying for before any additional work starts. We do not build in surprises.
Upfront Quotes With No Surprise Fees
We give you a straight quote before work begins. If something unexpected comes up mid-job, we explain it and get your approval before we proceed. You know what you are paying for at every step.
When should I call an electrician instead of trying to fix it myself?
Any work that involves the panel, new wiring, circuit additions, or anything behind the wall is work for a licensed electrician. The same goes for outlets or switches that are warm to the touch, smell like burning, or make buzzing sounds. Replacing a light bulb or a plug-in device is one thing; anything that involves the wiring itself carries real risk if it is not done correctly. When in doubt, a quick call costs nothing and can tell you whether it is something you can handle or something we should look at.
Is same-day electrical service available?
Yes. Same-day service is available throughout Northridge and the surrounding communities. Calling early in the day gives you the best chance of a same-day appointment. We also take after-hours calls when the situation genuinely cannot wait.
What is whole-home surge protection and is it worth it?
A whole-home surge protector installs at the panel and shields every circuit in the house from voltage spikes. That covers appliances, home theater equipment, computers, smart-home devices, and anything else plugged into a wall. In the Los Angeles area, where wildfire-season grid events and utility fluctuations are a real concern, it is a practical layer of protection. The install is straightforward and pairs naturally with a panel upgrade if you are already having panel work done.
