Centennial Electrician Serving the Whole South Metro

If you need a Centennial electrician, the license number matters as much as the phone number. All Electric holds CO License #ME.0600978 and carries full insurance on every job, so you're covered from first wire to final inspection. Daniel Vargas has been doing this work for 9 years, and the 4.9-star average across 468 Google reviews reflects what happens when a licensed contractor shows up prepared, explains the work plainly, and backs every job with a 1-year labor warranty. Call (720) 951-4619 and we'll get you scheduled.

We run calls throughout Centennial and the surrounding south metro, including Foxridge, Willow Creek, Piney Creek, and the neighborhoods south of Arapahoe Road. Centennial's housing stock skews late 1970s through the 1990s, which means we see a lot of 100-amp panels that need upgrading, older wiring that doesn't meet today's code, and homeowners who've added square footage without adding circuits. We know what's inside those walls because we've opened them. If you're also comparing options in nearby areas, take a look at our Electrician South Denver CO page for more context on coverage.

Electrical Services We Run in Centennial Centennial

From a single faulty outlet to a full panel replacement, we handle the full range of residential and light commercial electrical work.

Panel Upgrades

A lot of Centennial homes still run on 100-amp service. That was fine in 1982. It's not fine when you're running a heat pump, two EV chargers, and a home office. We pull the permit, do the upgrade to 200-amp, and get it inspected.

EV Charger Installation

Level 2 home charger installs are one of the fastest-growing requests we get from Centennial homeowners. We handle the dedicated circuit, the permit, and the charger mount. Most installs wrap in a single visit. See our full EV charger installation service for details.

Electrical Repair and Troubleshooting

Flickering lights, tripped breakers that won't reset, outlets with no power. These aren't nuisances, they're symptoms. We diagnose the actual cause instead of swapping parts until something sticks.

GFCI Outlet Installation

Kitchens, bathrooms, garages, and outdoor receptacles all require GFCI protection under current code. If your Centennial home was built before 1990, there's a good chance some of those circuits aren't up to standard. We install them properly and label everything. Learn more about GFCI outlet installation.

Interior and Exterior Lighting

We install recessed lighting, pendant fixtures, landscape lighting, and security lighting throughout Centennial. If the wiring behind an old fixture is undersized or deteriorated, we tell you before we start. No surprises mid-job. Full details on our interior and exterior lighting work.

Light Commercial Electrical

We're not residential-only. If you operate a small business in Centennial, we can handle service panel work, dedicated circuits, code violation corrections, and new circuit installation. See our light commercial electrical services.

Why It Matters

Older Centennial Homes and What's Actually Inside Them Inside

panel upgrades work, project example in Centennial, CO

The electrical systems in 1980s and early 1990s construction weren't designed for how people live today.

Centennial was built out fast. Most of the residential stock went up between 1978 and 1998, and the electrical systems inside those homes reflect that era's code, not today's. That means 100-amp main service, two-prong outlets in bedrooms, missing GFCI protection, and aluminum branch wiring in some of the older builds. None of that is catastrophic on its own, but it becomes a problem the moment a homeowner starts adding load. A finished basement, a home addition, a new HVAC system, an EV charger: any one of those can push an older panel past what it was designed to handle. We've also written about whether to replace aluminum wiring if that's something you're dealing with. We don't tell every Centennial homeowner they need a panel upgrade. Honestly, some 100-amp panels handle modern loads just fine, especially in smaller homes without high-draw appliances. What we do is assess what you actually have and tell you the truth about it. That's the job.

Common Questions from Centennial Homeowners Centennial

Do I need a permit for electrical work in Centennial?

Most non-cosmetic electrical work in Centennial requires a permit through Arapahoe County or the City of Centennial, depending on where your property sits. Panel upgrades, new circuits, EV charger installs, and service changes all require permits and inspections. We pull every permit that's required on jobs we take. If a contractor tells you they can skip the permit to save you money, that's a red flag, not a deal. Unpermitted work creates problems at resale and can void your homeowner's insurance coverage.

How much does a panel upgrade cost in Centennial, CO?

Panel upgrade pricing in Centennial depends on the existing service size, the condition of your meter loop, whether the panel location changes, and the permit fees specific to your jurisdiction. We don't publish ranges because a number that fits one home's situation misleads the next homeowner. Every job is different. Contact All Electric for an accurate estimate. What we can say: we tell you the full cost before any work starts, and financing is available for larger upgrades.

What neighborhoods in Centennial does All Electric serve?

We run calls throughout Centennial, including Foxridge, Willow Creek, Piney Creek, Smoky Hill, Walnut Hills, Hunters Hill, and neighborhoods along University Boulevard and south toward Highlands Ranch. Centennial is one of our regular service areas, not a long-distance run. We also cover adjacent areas including Greenwood Village, Parker, and Lone Tree. If you're not sure whether your address falls in our range, call (720) 951-4619 and we'll confirm in under a minute.

My Centennial home was built in the 1980s. What electrical problems should I expect?

Homes built in Centennial between roughly 1978 and 1995 typically show a few recurring issues: 100-amp service that's undersized for modern load, missing GFCI protection in wet areas, two-prong outlets in older bedrooms, and occasionally aluminum branch wiring on 15 and 20-amp circuits. None of these are emergencies on their own, but they do need attention before you add significant load or list the home for sale. We can assess all of it in one visit and prioritize what actually needs to happen now versus what can wait.

Can All Electric install a Level 2 EV charger at my Centennial home?

Yes. Level 2 EV charger installation is one of our most common jobs in Centennial right now. We run the dedicated 240V circuit, pull the required permit, mount the charger, and handle the inspection. Most installs take a single visit. If your panel is already at capacity, we'll tell you upfront, and a panel upgrade can often be combined with the charger install. We're familiar with permit requirements in Centennial and Arapahoe County, so there are no surprises mid-project.

Does All Electric handle attic fan installation in Centennial?

Yes. Attic fan installation is a straightforward job that makes a real difference in summer cooling costs for Centennial homes, particularly those with south or west-facing roof slopes. We run the circuit, install the fan, and connect any thermostat controls. It's a faster job than most homeowners expect. You can see more about that service on our attic fan installer page, or call to discuss your specific setup.
