When a property in San Dimas changes hands or a new tenant moves in, the electrical system needs to be documented, not assumed. We handle the full range of residential and commercial electrical work here, from a single outlet that stopped working to a panel replacement that brings the service up to what the building actually draws. Whether you own a home, manage a rental, or oversee a commercial space, the process starts the same way: call, describe the job, and get a price before anything is scheduled.
San Dimas is a city where a significant share of the housing stock was built in decades when 100-amp service and two-prong outlets were the standard. That wiring was adequate then. It is not adequate now, and the gap between what exists and what a household or business actually needs is where most of the calls we receive begin. We work across the city every day from 6 AM to 9 PM.
An electrical inspection for a property sale or new tenancy covers the panel first. We check the breaker condition, the labeling, the bus connections, and whether the service amperage matches what the building draws under real load. From there the inspection moves through the circuits: GFCI protection in wet areas, AFCI protection on bedroom and living-space circuits, grounding at outlets throughout the home, and the condition of visible wiring in the attic, crawl space, and at the service entrance.
Older homes in the area sometimes carry knob-and-tube wiring or aluminum branch-circuit wiring, both of which need specific evaluation rather than a general pass. Knob-and-tube is ungrounded and cannot safely support modern receptacles or arc-fault protection without remediation. Aluminum branch-circuit wiring requires listed connectors and correct termination at every device. The inspection documents what is there so the buyer, seller, or landlord knows what they are working with.
After the inspection, you have a written record of the panel condition, the circuit inventory, the grounding status, and any items that need attention. That record matters when a property changes hands, when an insurer asks about the electrical system, or when a tenant raises a concern about something that was already documented. We produce that documentation as part of the inspection visit, and the findings are explained on-site before we leave.
Planning is different for a commercial or light industrial property than it is for a home. A business that has to stay open during the work, a warehouse that cannot have its refrigeration circuit go down, or an office that runs on a server room with no tolerance for an unplanned outage all require a different approach to sequencing and isolation.
We handle commercial electrical work in San Dimas with that constraint in mind from the start. Out-of-hours scheduling is part of how we take on these jobs. If the work has to happen before the business opens or after it closes, that is what we arrange. If part of the site needs to stay live while another section is de-energized, the job is planned around that before anything starts.
Load calculations for commercial spaces are more involved than residential ones. A tenant improvement that adds kitchen equipment, server infrastructure, or manufacturing tools changes what the panel has to carry, and the panel work has to reflect that. We scope the electrical side of a buildout or a change-of-use project on the call so the job is sized correctly before anyone shows up.
A price for electrical work is not a flat rate because the job is not a flat job. What the fault turns out to be matters. What has to be opened up to reach it matters. Whether the existing circuit can carry the change, or whether the panel has room for a new breaker, matters. A straightforward outlet replacement and a knob-and-tube remediation are both electrical work, but they are not the same conversation.
The things that most commonly change a quote are the wiring type already in place, the panel capacity available, the access required to run new wire, and whether a permit is part of the job. We talk through all of those on the call so the number you get reflects the actual job, not a best-case estimate that grows once the wall is open.
Call (949) 514-6953 and describe what you are seeing or what you need done.
We scope the job on the phone and give you a price before anything is scheduled. If the job requires a site visit to scope it properly, that happens before any work begins and you know what it covers. There are no forms and no waiting for a callback to find out where you stand.
When a job is finished, the panel is labeled correctly, circuits are identified, and any permits pulled for the work are closed out through the appropriate inspection. That documentation is not a formality. It is what a buyer's inspector looks at, what an insurer references, and what the next electrician needs when they open the panel years later.
For a panel upgrade or a rewiring project, the finished work reflects the load calculations that went into it. A panel sized to what the building actually draws, with correctly rated breakers on correctly sized wire, leaves a record that the system was thought through rather than patched. We service this area, and its neighborhoods each have their own wiring. What is behind the walls in a mid-century ranch house is a different conversation from what is behind the walls in a newer build, and the documentation after the job reflects that difference. There is more on the page covering our electrical services.
We know schedules shift, so we keep booking flexible, and that applies to both planned work and problems that come up without warning. A tripped main breaker, a burning smell from the panel, or a circuit that goes dead mid-day are not situations that wait for a convenient slot. We take those calls and work to get them on the schedule as quickly as the situation demands.
For tenants and businesses that have to stay operational, we confirm what will be without power and for how long before the visit. If the work can be sequenced to keep part of the building live, we plan it that way. The scope and the price are settled on the call, and the visit starts with confirming what was discussed. No part of that changes between the phone and the door.
Availability runs every day from 6 AM to 9 PM.
Call (949) 514-6953 and we will confirm what the schedule allows for your address.
A dryer, range, refrigerator, or dishwasher draws enough current that sharing a circuit with other loads causes nuisance tripping and, over time, puts stress on both the breaker and the appliance. A dedicated circuit isolates the load on its own breaker with correct wire gauge for what the appliance draws. EV chargers in particular need a dedicated 240-volt circuit, and the panel has to have room to carry it. If it does not, a service upgrade is part of the same project.
Properties in and around San Dimas that rely on well pumps or run irrigation systems need circuits sized for motor loads, which behave differently from standard resistive loads. A pump circuit that trips intermittently under start-up load points to a breaker that is undersized for the inrush current the motor draws. We size the circuit for the actual load, including the start-up demand, and confirm the grounding is correct before the job is done.
An intermittent fault is the hardest kind to diagnose because it is not always present when the electrician arrives. A breaker that trips under certain conditions, a light that flickers only at night, or an outlet that works sometimes and not others all require tracing the circuit under load rather than checking it at rest. We work through the panel, the wiring path, and the device to find where the fault actually lives rather than replacing components until the symptom stops.
Outdoor outlets in Los Angeles County are required to have in-use covers and GFCI protection. An outlet that was installed without a weatherproof enclosure, or whose cover has cracked and no longer seals, is both a code issue and a practical one. We install weatherproof outlets and enclosures for patios, garages, driveways, and irrigation control panels, and we confirm GFCI protection is in place on every outdoor circuit we touch.
Electrical work across this part of Los Angeles County is what we do every day. Beyond San Dimas, we serve La Verne, Charter Oak, Glendora, Pomona, and Covina regularly. If you are in one of those cities or in the surrounding area, call and we will confirm coverage for your address.
The county spans a wide range of housing ages and property types, and the electrical work that comes out of it reflects that range. Older homes on original wiring, newer builds adding EV charger circuits, commercial spaces changing use, and rental properties needing documentation before a lease are all part of the work we handle across this area.
It does. When multiple properties lose power simultaneously, the fault is almost always on the utility side of the meter rather than in the building's wiring. We can confirm whether the issue is yours alone or shared, but if the utility is responsible, the repair is theirs to make.
Yes. If a generator is connected without a proper transfer switch, or if the wiring does not meet current standards, we can assess the setup and correct it. The most common issue is a generator connected directly to the panel without isolation from the utility line, which is both a code violation and a safety hazard. We explain what the correct installation involves and quote the work on the call.
The circuit that powers an electric gate, meaning the dedicated supply run from the panel to the gate location, is our work. The gate mechanism itself is a separate product. We handle the circuit, the weatherproof outlet or hardwired connection, and any panel capacity work the supply requires.
They can be. If you can describe what you see or send a photo through before the visit, it helps us understand what we are working with and prepare accordingly.
Call (949) 514-6953 and we will tell you what information is most useful for the specific job.
Yes, and it is one of the main things that moves a quote. Homes built before the 1970s often have wiring that requires specific remediation rather than a straightforward swap, and the access needed to reach it can add to the scope of the job. We evaluate what is in place before recommending anything, so the number you get on the call reflects the actual wiring situation rather than a best case.
Permit requirements depend on the type and scope of the work and on whether it is inside the city limits or falls under county jurisdiction. Panel upgrades, service entrance work, and new circuit installations typically require a permit and a follow-up inspection. We confirm what applies to your job before the work starts and handle the permit process as part of the project.
For multi-day jobs, we plan the work so power is restored to as much of the property as possible at the end of each day. The specifics depend on the job sequence and what is safe to energize at each stage. We discuss the plan before the job starts.
It should be. The circuit layout for a kitchen, including the dedicated circuits for the refrigerator, dishwasher, and microwave, the GFCI outlets along the countertops, and the supply for the range, needs to be roughed in before cabinets and countertops are installed. We can scope the electrical work from the kitchen plan before installation begins.
Electrical faults do not improve on their own. A breaker that trips repeatedly, a burning smell near an outlet, or a panel that runs warm are all reasons to call promptly rather than wait for a more convenient moment.

Electrical work covers a wide range of jobs, and knowing what each one involves helps you make a faster, more confident call. The table below breaks down the services we handle across San Dimas and Los Angeles County, what each one covers, and who it is most useful for. If a job is not on your radar yet, the FAQ section below covers the questions homeowners and property managers ask most often before they pick up the phone.
| Service Type | What's Included | Common Situations | Worth Knowing |
|---|---|---|---|
| Lighting Installation | Recessed LED and fixture installation, Under-cabinet and landscape lighting, Motion sensor and security lighting, Commercial and retail lighting circuits | Homeowners upgrading fixtures, adding outdoor lighting, or wiring a remodel | Outdoor lighting circuits in Southern California get year-round use, so weatherproof boxes and correct circuit sizing matter more here than in seasonal climates. |
| Electrical Panel and Service Upgrades | Panel replacement and load calculation, Fuse-box-to-breaker conversion, 200-amp service upgrades, Subpanel installation | Older homes, properties preparing for sale or renovation, and any home adding EV charging or solar | A 100-amp service is often the limiting factor in older San Dimas neighborhoods. Upgrading to 200 amps resolves capacity issues and brings the service entrance up to current standards. |
| Ceiling Fan Installation | Fan-rated box installation, New circuit and switch wiring, Fan replacement and upgrade, Remote and dimmer compatibility | Any room adding a ceiling fan for the first time or replacing an existing unit | If the existing ceiling box is not rated for a fan, we replace it before the fan goes up. Skipping that step is the most common reason a fan wobbles or makes noise. |
