Thousand Oaks is a city where homeowners are running more load than ever, rental properties turn over on a schedule, and businesses cannot afford a wiring problem to stop operations mid-day. Coleman Electrical Service handles electrical repairs, panel upgrades, circuit installation, and full rewiring across Thousand Oaks and the surrounding area. Whether you own the home you live in, manage a portfolio of rental units, or run a commercial space that has to stay functional, we handle the electrical side of it. We are available every day from 6:00 AM to 10:00 PM, and same-day appointments are often available.
Property managers in particular call us for the kind of work that stacks up between tenants or shows up on an inspection report. Homeowners call when something stops working and they want it diagnosed correctly rather than patched. Businesses call when a circuit is undersized for the equipment they are running or when a panel is holding back what the space needs to do. Whatever the situation, you get a price on the call before anything is scheduled, and work is carried out by licensed electricians who know what California code requires.
Getting your power back is easier than you think, and the first step is a phone call. When you call, we ask what you are seeing, where the problem seems to be, and what the space is used for. From that conversation we give you a price and confirm what it covers. You know the cost before we schedule anything.
Same-day appointments are often available for Thousand Oaks calls, though we cannot promise a specific arrival window until we confirm the schedule. For situations that will not keep, such as a sparking outlet, a burning smell near a panel, or a complete loss of power in part of a building, let us know when you call and we prioritize accordingly. For businesses that have to stay open, we plan the work around your hours and isolate only what needs to be isolated, so the rest of the space keeps running. We show up, and we keep you posted until the job is done.
A vacancy is the easiest window an electrical job ever gets. There is no one to work around, no schedule to protect, and no tenant whose daily routine gets interrupted by a circuit being isolated or a panel being replaced. If a property has been flagged for missing GFCI protection, an outdated panel, or wiring that needs to be brought up to code before the next occupancy, this is the time to handle it.
Access is straightforward when a unit is empty. We coordinate directly with the property manager or owner, confirm what is needed before we arrive, and handle the work without the back-and-forth that a tenanted property requires. For landlords running multiple units in Thousand Oaks, we can look at several properties in a single visit if the schedule allows. Reach out and an electrician will follow up.
California's EV adoption rate means a Level 2 charger has become a standard ask in Thousand Oaks, both for homeowners adding one to a garage and for landlords making a rental property more competitive. A Level 2 charger runs on a dedicated 240-volt circuit. We check available panel capacity, run the circuit to the right location, and install the charger itself. If the panel needs room to support the new load, we handle that as part of the same project. A load calculation is part of every EV charger job so the panel is sized for what it is actually being asked to carry.
Electric ranges, wall ovens, and dryers each need their own dedicated circuit sized to the appliance. When a kitchen is being renovated, an appliance is being swapped from gas to electric, or a laundry hookup is being added to a space that did not have one, we run the circuit from the panel and confirm the breaker is correctly rated. These are not circuits that share capacity with other loads.
Thousand Oaks has a range of housing ages, and older homes can carry wiring that was never designed for the loads a modern household puts on it. Knob-and-tube wiring and aluminum branch-circuit wiring both require specific approaches rather than a generic fix. We handle whole-home rewires, partial rewires for additions and remodels, and targeted aluminum-wiring remediation where only certain circuits are affected. The scope is determined by what the inspection actually finds, not by a default recommendation.
An outdoor outlet that is not properly weatherproofed is a code issue and a safety issue. We install weatherproof outlets and enclosures for patios, garages, side yards, and commercial exteriors, with GFCI protection where California code requires it. If you are adding outdoor lighting, a fountain pump, or a charging station in an exterior location, the outlet needs to be installed correctly from the start.
A whole-home surge protector installs at the main panel and intercepts voltage spikes before they reach appliances, electronics, and circuits throughout the building. In a region where public-safety power shutoffs and grid restoration events are a recurring reality, that protection is worth having. We check grounding and bonding as part of the installation, because the protector works correctly only when the grounding system behind it is solid. We give honest recommendations on repairs, never an upsell, and surge protection is a genuinely useful addition for homes and businesses here.
Workshop equipment draws a lot of current, and most residential panels were not sized with a welder or an air compressor in mind. We run dedicated circuits for workshop and garage equipment, sized to the actual load the equipment requires. That means a load calculation before the circuit is run, and a breaker rated correctly for what is on it. Code-compliant wiring on every job means the circuit will pass inspection and will not trip under normal use.
For what the job actually entails, the electrical repair page lays it out.
When you call, you get a price based on what you have described. We explain what the job involves, what the rate covers, and what would change the quote if the situation turns out to be more involved than the initial call suggested. Pricing is clear and explained up front. If you have questions about what is included, ask on the call and you will get a straight answer.
What changes a quote is usually access or scope. Wiring that runs through finished walls or attic spaces is harder to reach than wiring in an open basement. A panel replacement that also requires a service-entrance upgrade is a different job from a straight panel swap. If we find something during the work that changes the scope, we tell you before continuing. You make the call from there. The service page carries the full breakdown of what each type of job involves.
Not every electrical job requires a full shutdown. Many repairs and installations need only one circuit isolated, which means the rest of the home or business keeps running normally while the work is done. A panel replacement or a service upgrade is a different matter. That work requires the main service to be de-energized, and everything in the building goes off for the duration.
For homeowners working from home, we confirm in advance which circuits will be affected and for roughly how long, so you can plan around it. For businesses, we schedule panel work outside trading hours where possible, or we work through the logistics with you before the appointment is confirmed. We let you know who is coming and what to expect before anyone arrives. Pick up the phone and we'll get rolling.
A repair call usually starts with a symptom: a breaker that trips repeatedly, an outlet that stopped working, a light fixture that flickers when something else on the circuit runs. We trace the problem from the symptom back to the source rather than addressing only what is visible. That might mean checking arc-fault and ground-fault breakers, testing for a loose connection behind a switch plate, or finding a wiring fault that has been building for a while. An electrical safety inspection follows the same process, and often turns up issues that a symptom-only call would miss.
A panel upgrade call comes out of a few different situations. A home inspector flags the existing panel. A new appliance or EV charger needs capacity the current panel cannot provide. A breaker keeps tripping because the circuit is consistently overloaded. We assess the actual load before recommending a panel size, so the upgrade is right for what the home or business is running now and what it is likely to run in the future. Backup generator hookups and battery backup connections also run through the panel, and we handle that wiring as part of the same project when the timing works.
Installation calls cover a wide range: ceiling fan wiring, dedicated circuits for new appliances, outdoor lighting, EV chargers, surge protection, and new outlet and switch locations. Each one starts with a look at the panel to confirm there is capacity for what is being added. If there is not, we explain what a panel upgrade would involve and let you decide how to proceed. The service page carries the full breakdown of installation types and what each involves.
We serve Thousand Oaks and the surrounding communities throughout Ventura County, including Westlake Village, Oak Park, Santa Rosa Valley, Casa Conejo, and Lake Sherwood. Whether the job is in a single-family home, a multi-unit property, or a commercial building, we cover the area and can often schedule the same day.
We'll handle the wiring so you don't have to.
When there is no existing ceiling box or wiring at the spot where a fan is going, we run a new circuit from the panel, install a rated ceiling box that can support the fan's weight, and wire the controls. If the location already has a light fixture, the existing wiring may be usable depending on how it was run and what it is rated for. We assess that before committing to a scope.
It is a good idea to keep pets out of the work area. Tools, open wall cavities, and de-energized circuits are all hazards for an animal that wanders into the space. We do not require the whole property to be cleared, just the rooms where the work is happening.
It depends on what was done and whether it can be brought to code without starting over. Some amateur work can be corrected at the connection points and made safe. Other installations have to come out because the wiring method, the wire gauge, or the routing does not meet current code. We assess it honestly and explain what the options are.
Yes, we give you a price on the call before anything is scheduled. We ask what you are seeing and where the problem seems to be, and from that we can tell you what the job covers and what it will cost. If the work turns out to be more involved than the call suggested, we tell you before continuing.
A written record of the electrical condition of the property, what was inspected, what was corrected, and what circuits and devices were tested, gives a landlord documentation that the property was in safe condition at the start of a tenancy. We provide a clear account of what was found and what was done as part of any inspection or repair visit.
Yes, and it often saves time later in the transaction. A pre-listing inspection identifies wiring issues, missing GFCI or AFCI protection, and panel concerns before a buyer's inspector finds them, which gives you the option to address them on your own schedule rather than under contract pressure. We document what we find and what was done, so you have a clear record to share if it comes up during the sale.
Yes, significantly. Knowing whether a breaker trips at a specific time of day, when a particular appliance is running, or only when multiple things are on at once gives us a much clearer starting point for diagnosis. Patterns narrow down whether the cause is a failing device, an overloaded circuit, or a wiring problem.
Outdoor outlets in wet or damp locations require GFCI protection and weatherproof covers rated for the exposure. Outlets near a pool or pond are also subject to specific clearance requirements under the electrical code. We install to those requirements and confirm the installation is correct before we leave.
We run a load calculation based on what the panel is currently serving and what the new load will add. That tells us whether the existing service has the capacity to handle the addition or whether a service upgrade is needed first. Adding load without checking capacity can cause repeated tripping or create a fire risk.
Sometimes, and sometimes not. It depends on how much available capacity the panel has and what the equipment actually draws. We run a load calculation before the circuit is run so you know going in whether the panel can support the addition or whether an upgrade needs to happen first. We will explain what we find on the call and give you a price for each path.
If multiple homes lose power simultaneously, the cause is likely on the utility side rather than inside your home. We can confirm whether the issue is at the meter or the service entrance, but if the utility's supply is out, the repair is theirs to make. We help you determine which side of the meter the problem is on.

| Service Type | Scope of Work | Best For | Things to Know |
|---|---|---|---|
| Hot-Tub Circuits | 240-volt dedicated circuit, GFCI disconnect installation, outdoor wiring and conduit, bonding and grounding | Homeowners installing a spa or hot tub and needing the electrical side handled correctly | Hot tub wiring involves specific code requirements for GFCI protection and bonding. Getting it right the first time avoids problems at inspection. |
| Breaker & Fuse Repair | failing breaker replacement, fuse panel evaluation, overcurrent protection checks, panel interior inspection | Homeowners with a breaker that trips repeatedly or will not reset | A breaker that keeps tripping is doing its job, but the underlying cause still needs to be found and corrected. |
| Standby Battery for Outages | battery backup wiring, transfer switch installation, critical load panel setup, grid-tie and off-grid configurations | Homeowners who want power for essential circuits when the grid goes down | Sizing the battery correctly starts with knowing which circuits you need to keep running. We work through that on the call before anything is scheduled. |
| Electrical Repairs & Troubleshooting | tracing faults to the source, testing outlets and circuits, arcing and loose connection repair, GFCI and AFCI protection | Any home or business with a symptom that needs a diagnosis | A tripping breaker or dead outlet can point to something deeper. We identify the real problem before recommending a fix. |
| Outlet & Switch Installation | GFCI outlet installation, switch replacement and upgrade, dedicated outlet runs, exterior and weatherproof outlets | Homeowners adding outlets or replacing devices that have stopped working | GFCI protection is required by California code in kitchens, bathrooms, garages, and outdoor locations. We install to current code on every job. |
| Older-Home Rewiring | knob-and-tube replacement, aluminum branch-circuit remediation, partial and whole-home rewires, wiring for additions and remodels | Owners of older Thousand Oaks properties with wiring that has been flagged or is showing symptoms | The scope of a rewire depends on what is actually in the walls. We assess the existing wiring before recommending a full or partial approach. |
| Whole-Home Surge Protection | panel-mounted surge protector installation, grounding and bonding verification, protection for appliances and electronics, EV charger circuit protection | Any home with sensitive electronics, an EV charger, or solar equipment worth protecting | A surge protector at the panel intercepts voltage spikes before they reach your devices. Grounding and bonding are checked as part of the installation. |
| Wiring & Circuit Installation | new circuit runs, renovation and addition wiring, garage and shed wiring, code-compliant rough-in work | Additions, conversions, and any space being built out or rewired | New wiring in California is inspected to code. We handle the load calculation and panel capacity check as part of the project. |
| Electrical Panel & Service UpgradesMost Popular | 200-amp service upgrades, panel replacement, subpanel installation, load calculations and grounding | Older homes, properties under renovation, or any panel flagged during an inspection | Many Thousand Oaks homes were built with 100-amp service. A load calculation before the upgrade confirms the new panel can carry what you are adding. |
| Electrical Safety Inspections | panel and wiring condition review, GFCI and AFCI check, grounding and bonding evaluation, pre-sale and rental unit inspections | Landlords, buyers, sellers, and anyone with an older property | A written summary of findings comes with every inspection so you know exactly what was found and what, if anything, needs attention. |
| Dedicated Appliance Circuits | dryer and range circuits, hot tub and spa wiring, workshop and garage circuits, disconnect and breaker installation | Any high-draw appliance that needs its own breaker and wire run | Running a dedicated circuit means the appliance does not compete with other loads on the same breaker, which reduces nuisance tripping and wear. |
| Lighting Installation | recessed and LED lighting, kitchen and bathroom lighting, exterior and security lighting, landscape lighting circuits | Remodels, new construction, or any space where the existing lighting is not working for the room | Exterior and landscape lighting circuits need proper weatherproofing and grounding. We handle the circuit run, not just the fixture. |
| Solar & Battery Backup | transfer switch installation, battery backup wiring, panel capacity and interconnection work, critical load circuit setup | Homeowners adding solar or battery storage, especially ahead of wildfire season outages | Public-safety power shutoffs across Ventura County have made battery backup a practical choice. We handle the electrical side so the system actually works when the grid goes down. |
| Ceiling Fan Installation | fan and fixture swap, new circuit and wiring runs, box and brace installation, switch and remote wiring | Homeowners replacing an old fan or adding one where no wiring exists | If there is no existing wiring at the ceiling location, we run the circuit from the panel. No guesswork on whether the box can hold the weight. |
| EV Charger Installation | Level 2 charger installation, dedicated 240-volt circuit, panel capacity check, garage and driveway placement | Electric vehicle owners who need faster overnight charging than a standard outlet provides | California has some of the highest EV adoption in the country. If the panel needs room for the new circuit, we handle that as part of the same visit. |
