Every home's wiring tells a different story, and after more than three decades of work across the San Fernando Valley, we have seen just about every chapter. J-Masters Electric has been serving Northridge and the surrounding communities since 1990, and same-day electrical service is available when the job cannot wait. Work is performed by licensed electricians who show up prepared, diagnose the problem correctly, and get it done right the first time.
Honest quotes. Code-compliant work. Reliable power.
Whether you own a single-family home, manage a rental portfolio, or run a commercial space, call (818) 369-3955 to get a quote and get on the schedule.
When the power goes out in one room, or a breaker trips for the third time this week, the underlying cause is rarely obvious from the surface. Flickering lights, dead outlets, sparking receptacles, a faint burning smell behind a wall plate -- these are the calls we take every day, and every one of them gets a proper diagnostic before any repair begins.
We trace the problem to its source. That might mean a failing breaker, a loose connection, a wiring fault, or a receptacle that has simply worn out. Where code calls for arc-fault or ground-fault protection, we install it correctly. GFCI outlets in kitchens, bathrooms, garages, and outdoor locations are a common repair and upgrade we handle on a regular basis.
Urgent electrical problems should not sit on a waiting list. We show up ready to work.
A properly wired home is a safer home, and the panel is where that safety starts. Older panels that cannot keep up with modern electrical loads are a real risk. We handle full breaker panel replacements, service panel upgrades, individual circuit breaker replacements, and the load calculations that tell you exactly what your home or building can safely carry.
Dedicated circuits matter more than most homeowners realize. A dryer, an oven, a refrigerator, a dishwasher -- each of these appliances performs better and runs more safely on its own circuit. We install 240-volt circuits for large appliances and run the dedicated electrical supply for HVAC equipment as well, covering the circuit, disconnect, and any panel capacity work the load requires.
For additions, garage conversions, and remodels, subpanel installation keeps the new work clean and code-compliant without overloading the main service. We also handle service-entrance and meter upgrades when the utility requires it.
We stand behind every circuit we touch.
From older homes to new commercial builds, the day-to-day electrical work that keeps a property functional comes down to outlets, switches, and lighting. We install and repair standard outlets, GFCI and AFCI protected receptacles, weatherproof outdoor outlets, and garage circuits. Dimmer switches, three-way switch replacements, and USB outlet upgrades are straightforward jobs we turn around quickly.
Lighting is where a space really comes together. We handle recessed LED installations, light fixture replacements, under-cabinet lighting, and full outdoor lighting setups including security lights and motion sensor fixtures. Ceiling fan installation and wiring is another frequent call -- whether it is a new fan where no fixture existed before or a replacement that needs the box reinforced for the added weight.
Call and we'll handle the lights, outlets, and panel.
Older homes in the Northridge area carry wiring histories that range from solid mid-century work to genuine safety concerns. Knob-and-tube wiring, aluminum branch-circuit wiring, and ungrounded two-prong systems are all situations we handle regularly. Whole-home rewiring brings the entire system up to current code, and targeted remediation addresses specific problem areas without a full replacement when that is the right call.
Electrical safety inspections are valuable for any property owner. Buyers use them before closing. Landlords and property managers use them to stay ahead of code violations and keep tenants safe. We document what we find, explain what it means, and give you a clear picture of what the work will involve.
Being local means we're easy to reach and easy to work with. When a property manager in Los Angeles County needs an inspection turned around on a tight timeline, they can reach us directly and get a real answer.
This is the kind of electrical work neighbors pass along by word of mouth, and we take that seriously on every job.
We work across the full range of residential and commercial customers. Homeowners call us for repairs, upgrades, and remodels. Landlords and property managers rely on us to keep rental units and apartment buildings safe and code-compliant. Businesses -- offices, retail spaces, warehouses, restaurants -- need commercial electrical work done on a schedule that does not shut them down longer than necessary.
New construction wiring, home addition circuits, kitchen and bathroom remodel electrical, and commercial tenant improvements are all part of what we do. For larger commercial projects, we handle three-phase electrical service and full office or facility installations. We show up on time and ready to wire.
Call today and we'll set the appointment.
Southern California's energy landscape has shifted considerably over the past decade. EV ownership in this region leads the country. Rooftop solar is on a large share of homes across the Valley. And wildfire-season public-safety power shutoffs have made backup power a practical concern rather than a theoretical one. The three services below come up constantly in Northridge and the surrounding communities, and we handle each of them on the electrical side from start to finish.
A Level 2 home EV charger runs on a dedicated 240-volt circuit, and getting that circuit right starts with a panel capacity check. We assess your existing service, determine whether the panel can carry the added load, and run the circuit to your garage or driveway location. If the panel needs an upgrade before the charger goes in, we handle that as part of the same project. With EV adoption as high as it is in this area, this has become one of our most common residential calls.
We work on the electrical connection side of solar and battery storage systems. That means wiring the tie-in between a solar inverter or battery backup system and your home's panel, installing dedicated circuits, and making sure the panel has the capacity to handle the added load. We do not install the panels or the battery hardware itself, but we handle the electrical integration that makes the whole system function safely and to code. For homeowners adding storage to an existing solar setup, we bring the panel side into compliance and connect everything correctly.
Grid fluctuations during wildfire season, utility switching events, and the general instability that comes with high-demand periods on the California grid can send voltage spikes through your home's circuits. A whole-home surge protector installed at the panel catches those spikes before they reach your appliances, electronics, and wiring. It is one of the more affordable upgrades we offer relative to what it protects. Same-day electrical service is available if you want it handled quickly.
We quote the job before the work begins. No surprises on the invoice, no charges that were not discussed. If the scope changes once we are into the work, we tell you before we proceed.
Same-day availability means that urgent repairs do not have to wait until next week. We also schedule weekend appointments for customers who cannot take time off during the week. Getting a quote is a phone call away, and scheduling from there is simple.
Pick the date. We do the wiring. We clean up after.
Call (818) 369-3955 and we will get you on the calendar.
We serve Northridge and the neighborhoods around it throughout the western San Fernando Valley. That includes Reseda, Granada Hills, Chatsworth, Canoga Park, Winnetka, West Hills, Porter Ranch, and Tarzana. If you are nearby and need an electrician, we are close and we are available.
We start by assessing your panel to confirm it has the capacity to carry a dedicated 240-volt circuit. If an upgrade is needed first, we handle that as part of the same project. We run the circuit to your garage or driveway location, install the outlet or hardwired connection, and confirm everything is code-compliant before we leave.
It depends on your current service capacity and what else is already drawing from the panel. We perform a load calculation as part of every EV charger installation to determine whether the existing panel can carry the new circuit safely. If it cannot, we will explain the upgrade options and what each one involves before any work begins.
We handle the wiring, circuits, and panel work that connect a solar inverter or battery backup system to your home's electrical service. That includes dedicated circuits, transfer switches where needed, and any panel capacity upgrades required to carry the added load. We do not install the solar panels or battery hardware itself, but we handle the electrical integration from the panel side.
A whole-home surge protector is installed at the breaker panel and protects every circuit in the house from voltage spikes caused by grid fluctuations, utility switching events, or nearby lightning. It covers appliances, electronics, HVAC equipment, and anything else plugged into your home's wiring. The installation is straightforward and pairs naturally with panel work if you are already having the panel serviced.
Both present real safety concerns and can affect homeowners insurance coverage. Knob-and-tube wiring lacks a ground conductor and was not designed for modern electrical loads. Aluminum branch-circuit wiring can loosen at connections over time and create arc-fault hazards. We handle whole-home rewiring, knob-and-tube replacement, and aluminum-wiring remediation, and we can walk you through the options that make sense for your property.
Yes. Work that requires a permit in Los Angeles County is handled with the proper permits pulled and inspections scheduled. All work is performed by licensed electricians familiar with California electrical code and the permit process in this area. We do not skip permits to save time or money.
We start by asking about what you observed, including when it happens, which circuits or rooms are affected, and any recent changes to the property. From there we test the circuit, check connections, inspect the panel, and trace the fault to its source before recommending a repair. Finding the real cause rather than just the symptom is what makes a repair last.
Homes built in the mid-twentieth century were wired for much lighter electrical loads than modern households demand. Panels that were originally sized for 60 or 100 amps and branch circuits with only a few outlets per room were standard at the time. A panel upgrade, additional circuits, and new outlet installations are the right long-term fix rather than relying on power strips or resetting breakers repeatedly.
An outlet that is warm or hot to the touch, discolored, cracked, or no longer holds a plug firmly is past the point of a simple reset. A burning smell near a receptacle or visible scorch marks around the face plate are more urgent signs. These conditions indicate a wiring fault or a failed device that should be replaced promptly.
Yes. We can install GFCI outlets in locations that require shock protection even without a ground wire present, which is a code-accepted approach for ungrounded circuits. For full grounding throughout the home, we assess the existing wiring and discuss the options, which may include running new grounded circuits or a more comprehensive rewiring depending on the scope.
Clear access to the work area and to the breaker panel makes a real difference. If we are working in a finished space, moving furniture away from the walls and clearing the area around the panel ahead of time helps the job go smoothly. We will let you know if there is anything specific to prepare when we confirm the appointment.
Same-day service is available throughout Northridge and the surrounding communities. Call (818) 369-3955 as early in the day as possible and we will do our best to get to you the same day. We also take after-hours calls when the situation is urgent.
When there is no existing ceiling box rated for a fan, we install a fan-rated box that can support the weight and movement of a ceiling fan safely. We run the wiring, install the box, hang the fan, and wire the switch or remote control. It is a more involved job than a straight swap, but it is a routine call for our team.
J-Masters Electric has been doing this work in Northridge since 1990. Licensed electricians are on the job on every call, and same-day service is available when the situation calls for it.
Call (818) 369-3955 for a quote. We'll handle the lights, outlets, and panel.

If the panel needs capacity added to support it, we handle that as part of the same project. |
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.
