San Lorenzo is a city with a real mix of property types: post-war tract homes that have been added to over the decades, newer construction with modern panels, and commercial units that have changed hands and uses more than once. The electrical systems inside them reflect that history. Some are clean and straightforward. Others have circuits that were added without documentation, panels that are undersized for what they are being asked to carry, and wiring that predates current code by a generation or two.
We handle electrical work across San Lorenzo for property owners, landlords, and businesses that need the job done correctly and want to know what it costs before anyone shows up. Residential repairs, panel upgrades, dedicated circuit installation, EV charger wiring, and safety inspections are all part of what we do here.

The age of a house shapes the job before we even open the panel. A home built in the 1950s or 1960s may have a fuse box still in place, cloth-insulated wiring behind the walls, and outlets that were never grounded. A home from the 1980s might have aluminum branch-circuit wiring on the bedroom circuits, which requires specific remediation rather than a standard repair. A newer build might have a 200-amp panel but no capacity left for an EV charger or a battery backup system because every slot is already spoken for.
We service this area, and its neighborhoods each have their own wiring. That shapes how a job is planned, what materials it takes, and what the inspection covers before any work begins. Whether the property is a single-family home, a duplex, or a commercial unit that has been retrofitted more than once, the approach starts with understanding what is actually in the walls and at the panel.
Knob-and-tube wiring and aluminum branch-circuit wiring both come up regularly in San Lorenzo's older housing stock. Neither is automatically a crisis, but both require specific handling. Knob-and-tube cannot be covered with insulation and cannot be extended with standard cable. Aluminum wiring on branch circuits needs the right connectors and devices rated for aluminum contact. A safety inspection is usually the right first step, because it tells us exactly what the system contains before any remediation is planned.
GFCI and AFCI protection are part of the same conversation. Bathrooms, kitchens, garages, and outdoor circuits all require GFCI coverage under current code. AFCI breakers protect bedroom and living area circuits from arc faults that standard breakers do not detect. Where those protections are missing or failed, we address them as part of the job, not as an add-on.
A panel that was sized for a 1960s household was not designed for today's loads. When a property needs a dedicated circuit for an EV charger, a battery storage system, a new appliance, or a workshop, the first question is whether the panel has the capacity to support it. If it does not, a service upgrade or subpanel installation is part of the answer.
Subpanels come up often when a detached garage or an addition needs its own circuits without running everything back to the main panel. We handle the load calculation, the panel work, and the wiring from the main service through to the new subpanel. The scope is set on the call and the price is confirmed before anything is scheduled.
Electrical work like this comes up more than people expect, and the situations that lead to a call are usually more specific than "something stopped working." Here is what those situations actually look like.
Recessed lighting in a finished ceiling involves more than the fixtures themselves. The circuit has to carry the load, the boxes have to be rated for the installation, and the switch wiring has to match what the layout requires. LED retrofits into existing housings are straightforward when the housing and driver are compatible. When they are not, we sort out which fixture works and wire it correctly. This is also a good time to add a dimmer, which requires a dimmer-compatible LED driver and the right switch wiring.
A full rewire replaces every branch circuit in the building from the panel out. A partial rewire targets a specific area, a specific wiring type, or a specific set of circuits that have failed inspection or show signs of degradation. Both involve working through finished walls, which takes more time and care than new construction. We explain what will be opened up, how it will be patched, and what the finished job covers before any work begins.
Outdoor lighting circuits need weatherproof wiring, boxes rated for outdoor use, and GFCI protection where required. Motion sensor lights, security floodlights, and landscape lighting all pull from a circuit that has to be sized for the combined load. Where the fixture load warrants it, we run a dedicated circuit rather than tapping an existing indoor circuit that is already near capacity. This is worth planning at the same time as other exterior work, because opening the wall once is better than doing it twice.
Running power to a detached structure is its own project. The feed from the main panel has to be sized for what the structure will draw, whether that is a single light and outlet or a full workshop with a 240-volt circuit for a table saw or an EV charger. Underground runs require the right conduit and burial depth. Electric gate operators need a dedicated circuit and, in some cases, a low-voltage control circuit alongside the power feed. We scope these jobs against what the structure actually needs, not a minimum that will have to be redone in two years.
We are available every day from 8:30 AM to 11:00 PM, including evenings and weekends. For a problem that will not keep, call and describe what is happening. We take short-notice work when the schedule allows, and we confirm what is available when you call.
For rental properties and commercial units, we work around tenants and business hours where the job allows. A repair that only affects one circuit does not have to shut down the rest of the building. We talk through the timing on the call and confirm the plan before anyone shows up.
Some jobs only require one circuit to be isolated. Replacing an outlet, adding a switch, or extending a circuit in one room means the rest of the property stays live. Other jobs require the main power to be off for part of the work. Panel replacements, service upgrades, and work at the main service entrance all fall into that category.
We tell you in advance which circuits will be off and for how long. For someone working from home, that means knowing which room to move to and for how long. For a business that has to stay open, it means planning the work around the hours when the load is lowest or the space can be temporarily vacated. The timing is part of the scope conversation, not something that comes up after we arrive.
Where a job runs in stages, we sequence the work so the outage is as short as possible. Code-compliant wiring on every job means the work holds up when the inspector looks at it, and that the sequence does not have to be redone because a step was skipped.
The hardest part of an electrical problem is knowing when to call, but lighting is one area where the answer is usually visible. Fixtures that flicker under load, outdoor lights that have stopped working, and rooms that feel dim despite adequate fixtures are all worth addressing.
Recessed lighting and LED retrofits improve both the light quality and the circuit load in a room. Older incandescent or halogen fixtures draw significantly more current than their LED replacements. Swapping them out while other work is being done in the same area costs less than scheduling a separate visit. Ceiling fan installation comes up in this conversation too, because a fan-rated box and a dedicated switch leg are both easier to add when the ceiling is already being worked on.
A driveway light that stopped working may be a failed fixture, a tripped GFCI upstream, or a wiring fault in the outdoor run. Security lighting that covers entry points and dark corners of a property is worth doing correctly, with circuits that are properly weatherproofed and GFCI-protected. Landscape lighting is a separate circuit conversation from security lighting, because the load and the control method differ. We handle both and explain which approach fits the property before any work is scheduled.
When you call about a repair, an upgrade, or a new installation, the price comes from the scope of the work, not from a formula. What the fault turns out to be, what has to be opened up to reach it, and whether the existing circuit or panel can carry the change are the things that move the number.
A straightforward outlet replacement on a live circuit costs less than a repair that requires tracing a fault through a finished wall. A panel upgrade where the service entrance is already adequate costs less than one that requires a new service drop. We ask the right questions on the call to scope the job accurately, and we confirm the price before anything is scheduled.
We'll find the fault and fix it right. If the job turns out to be more involved than the initial description suggested, we explain what changed and what it means for the price before we continue. You are not handed a bill that does not match what you agreed to.
Call us and the rest is handled.
We handle electrical work throughout San Lorenzo and the surrounding communities in Alameda County. Property owners and businesses in Ashland, Cherryland, San Leandro, Hayward, and Castro Valley are all covered. Residential repairs, panel upgrades, rewiring, EV charger installation, and commercial electrical work are all part of what we schedule across the area.
Whether the job is in San Lorenzo or in one of the neighboring communities, the process is the same: the scope is set on the call, the price is confirmed before we schedule, and the work is done to the standard the job requires.
Panel upgraded. Circuits balanced. Home powered safely. It is worth a look at our wiring and panel services page before you call.
Sometimes, and sometimes not. Whether the main panel can support an additional circuit depends on the current service size and what is already connected to it. If there are open slots and the load calculation shows available capacity, we can run the new circuit without touching the panel. If the panel is already at or near capacity, a subpanel or service upgrade is part of the conversation. We work that out on the call before anything is scheduled.
A home sale or transfer is one of the most common triggers for an electrical inspection, because a buyer wants to know the condition of the wiring before closing and a seller may need to address findings before the transaction can proceed. We handle pre-purchase inspections and can work through a list of corrections that came out of a home inspection report. The scope is set on the call based on what the inspection identified.
Yes. The outlet positions, dedicated appliance circuits, and under-cabinet lighting wiring all need to be in place before cabinets are installed. Running new circuits or moving outlets after cabinets are in place means working around them, which adds time and cost. We can review the kitchen plan on the call and confirm what needs to be roughed in before the installation begins.
The EV charger needs its own dedicated 240-volt circuit regardless of whether solar is present. The question is whether the panel has the capacity to support the added load alongside the solar inverter connection and everything else already on the panel. We check the load calculation, confirm available capacity, and run the circuit to the charger location. If the panel needs an upgrade to support both, we handle that as part of the same project.
Not necessarily. Whether a business needs to close depends on what the work involves and where in the building it is located. We discuss the options on the call and plan the work to minimize disruption where that is possible. For work that requires a full shutdown, we confirm the timing in advance so the business can plan around it.
A home inspection finding about the wiring is the inspector's observation that something does not meet current standards or presents a concern. It is not a repair order, but it is a signal worth taking seriously. We can review the finding on the call and tell you what correcting it would involve, which gives you something concrete to work with during a sale or purchase negotiation.
Yes, and in practical ways. Homes built before the 1970s are more likely to have wiring types that require specific remediation, panels that are undersized for modern loads, and missing GFCI or AFCI protection that current code requires. An inspection in an older home covers all of those, not just the obvious faults. It tells you what the system contains and what it needs before any work is planned.
An electrical problem that gets set aside does not get smaller. A breaker that keeps tripping is telling you something about the circuit it protects. A flickering light in a room of an older home may be a loose connection or the beginning of a wiring fault. Waiting to see if it resolves on its own is not a plan.
