Most calls start the same way. Something in the house is not doing what it should. A circuit that keeps tripping, a room that lost power, an outlet that stopped responding, or a light that flickers when nothing obvious has changed. The job of figuring out what is actually wrong is part of what we do, and it often turns out to be a different problem than the one the caller described. Current Electric handles that diagnostic work alongside the repair or installation that follows, so you are not left with a fix that addresses the symptom and leaves the cause alone.
Cupertino's housing stock runs toward well-maintained single-family homes, and a city this size generates a steady mix of repair calls, panel work, and installation projects. Some of those come from homeowners updating older systems. Others come from property managers keeping rental units up to code, or from businesses that need electrical work done without shutting down for a day. We handle all of it, and we are open every day from 5:30 AM to 9:30 PM. Call (650) 614-5391 to get a quote and get on the schedule.
Landlords and property managers in Cupertino often book electrical work on units they do not live in, and that arrangement adds a layer of coordination that a standard appointment does not cover. When access runs through a tenant, we work around the tenant's schedule rather than the landlord's, and we confirm the visit window with whoever is actually opening the door. That keeps the job from stalling on a locked unit.
On the invoice side, whoever is paying needs to be named at the time of booking. If the property owner is covering the cost but the tenant is the point of contact on-site, we work that out before the visit so there is no confusion afterward. Landlords who need documentation for their records, including a description of what was found and what was done, can ask for that on the call and we will make sure it is included.
We answer when you call. We explain the work. We leave it safe.
Not every electrical problem originates inside the home. When a circuit goes dead or the whole house loses power, the first step is working out where the fault actually is. We check the panel, the service entrance, and the branch circuits to identify what we can see on our side. If the evidence points to the utility's equipment, the meter, or the service drop, we tell you that clearly and explain what the next step looks like with your utility provider.
When the problem sits inside the home's wiring, panel, or devices, we handle it directly. That includes breaker failures, wiring faults, grounding and bonding issues, and service-entrance conditions that are within the homeowner's responsibility. Wiring work is checked against code before sign-off, so the repair is not just functional but compliant.
If the fault is on the utility's side of the meter, we will not charge you for work we cannot do. We explain what we found, what the utility is responsible for, and how to report it. That clarity is more useful than a bill for a problem we did not solve.
The kind of electrical job a property generates depends on what the property is, how old it is, and how it has been used. A call from a house built in the 1960s with original wiring is a different situation than a call from a newer home adding an EV charger circuit. Neither is harder, but they are not the same job, and treating them the same way produces the wrong result. The service page carries the full breakdown of what each type of work involves.
The hardest part of an electrical problem is knowing when to call, and the answer is usually before the situation gets worse. Flickering lights, tripping breakers, warm outlets, and dead switches are all signs that something in the circuit needs attention. We diagnose the fault, explain what caused it, and fix it at the source rather than resetting the breaker and hoping.
Older homes in Cupertino sometimes carry panels that were sized for a different era of electrical use. When a household adds EV charging equipment, solar and battery storage, or a kitchen remodel, the panel has to be able to carry the additional load. We handle panel replacement, service-entrance upgrades, subpanel installation, and load calculations to confirm the system can support what is being added. A panel upgrade is also the right moment to add AFCI and GFCI protection where it is required by current code.
New circuits, outlet additions, lighting installations, and dedicated appliance circuits all fall into this category. These are not emergency calls, but they are still worth doing right. Code-compliant wiring and proper grounding matter whether the job is a single outlet or a whole-room renovation. We wire homes and businesses every day, and we are good at it.
Pricing depends on what the job actually involves, and that is not always obvious from the outside. A tripping breaker might be a failed breaker, an overloaded circuit, or a wiring fault that requires more investigation. The quote accounts for what we find, not just what the call sounded like when you described it.
When you call, we go through the scope of the job and give you a rate before anything is scheduled. If the work turns out to be more involved than the initial description suggested, we explain that before proceeding. You get a clear answer on the call about what the price covers, and the rate is confirmed before we begin. Call (650) 614-5391 and ask what the work will run. That is the right place to get that number.
Same-day electrical service is available for calls that cannot wait. For planned work, we schedule around what works for the property and the people in it. If a tenant needs to be home, we work with that window. If a business needs the work done before opening or after close, we talk through what is possible when you call.
We're ready to get your circuits working again. For urgent problems, call early and we will tell you honestly whether we can get someone out that day. For scheduled work, we confirm the appointment window so you know what to expect and can plan around it. The goal on every visit is to finish the job and leave the property in better shape than we found it.
The next job gets earned by doing this one right.
A detached garage or workshop that needs its own circuits requires a subpanel fed from the main panel in the house. We size the subpanel to the load, run the feeder, and wire the circuits inside the structure. This is a common request in Cupertino where homeowners are adding EV charging capacity to a garage or converting a workshop for heavier equipment.
A whole-home surge protector installs at the panel and intercepts voltage spikes before they reach any outlet or device in the house. In a home running EV charging equipment, solar inverters, and connected appliances, a single surge event can cause damage across multiple systems at once. Panel-level protection covers everything downstream from a single installation point, and it pairs naturally with a panel upgrade or new subpanel.
Ground-fault protection is required in kitchens, bathrooms, garages, and exterior locations. Arc-fault protection is required in bedrooms, living areas, and other spaces under current California code. Homes that have not had their wiring updated may be missing both. We install GFCI outlets and breakers, AFCI breakers, and combination devices where the code requires them, and we check that existing protection is actually functioning rather than just present.
Knob-and-tube wiring lacks a ground conductor, was not designed for modern electrical loads, and degrades over time. Where it has been modified or covered with insulation, the risk increases. Replacement involves running new branch circuit wiring through the affected areas, updating the panel connections, and confirming that the finished system meets current code. We assess the extent of the wiring and explain the options before any work begins.
Outdoor lighting needs circuits and weatherproofing that hold up to the conditions outside. We install security lighting, motion-sensor fixtures, landscape lighting, and exterior outlets. GFCI protection is required on exterior circuits, and we include it as part of the installation rather than as an add-on.
Properties with well pumps or irrigation systems need dedicated circuits sized to the motor load. We run those circuits, confirm the breaker is appropriately rated, and check that the wiring between the panel and the pump or controller is in good condition. If the existing circuit has been extended or modified in ways that no longer meet code, we address that as part of the same visit.
We serve Cupertino and the communities around it throughout Santa Clara County. That includes Loyola, Saratoga, Los Altos, Sunnyvale, and Santa Clara. If you are in the broader area and are not sure whether we cover your address, call and we will confirm. Most calls in this part of the county fall within our service area, and we will tell you directly if yours does not.
our guide to electrical work explains how the work is handled.
Save any open work and shut down equipment before the power goes off. For longer shutdowns, we let you know in advance which circuits will be affected and for roughly how long, so you can plan around it and protect anything sensitive.
Yes. A circuit mapping visit identifies what each breaker controls, labels the panel, and documents the layout. This is useful for older properties where the panel directory is missing, incorrect, or has never been filled in.
A full rewire involves opening walls, ceilings, and floors to run new cable throughout the home. We work in stages where possible to keep parts of the property livable, and we explain the sequence before starting so you know what to expect each day.
Yes. Where chasing into a finished wall would cause more disruption than the job warrants, surface-mounted conduit is a practical alternative. We explain the trade-offs and let you decide which approach makes more sense for the space.
Yes. Running circuits through crawl spaces and underfloor voids is a standard part of residential electrical work, particularly in older homes where that is the only practical route to certain areas of the house.
We cover Cupertino and the surrounding area, including Loyola, Saratoga, Los Altos, Sunnyvale, and Santa Clara. If you are outside those communities but still in Santa Clara County, call (650) 614-5391 and we will confirm whether your address falls within our service area.
We stop and explain what we found before doing anything beyond the original scope. You decide how to proceed with full information about what the additional work involves and what it costs.
Panel upgrades, EV charger circuits, and GFCI and AFCI updates are among the most common calls we get in this area, alongside standard repairs like tripping breakers and dead outlets. Older homes also generate knob-and-tube replacement work and grounding issues that were never addressed when the house was built. If you are not sure whether your situation calls for a repair or something more involved, describe what you are seeing on the call and we will help you figure out the scope.
Yes, and that is usually the most efficient way to handle a list of minor work. When you call, walk through everything you want addressed and we will confirm whether it all fits in one visit or whether the scope warrants splitting it across two.
It depends on the condition of the wiring, whether it meets current code, and whether it is rated for the new application. We inspect it before committing to reuse, and we explain what we find so you can make an informed decision.
Current Electric is ready to take your call for any electrical work in Cupertino, from a single outlet that stopped working to a full panel upgrade or EV charger installation. Pick the date. We do the wiring. We clean up after.
