Professional Electric Services
Licensed electrical work — done right the first time.
Common signs include frequently tripping breakers, flickering lights when appliances turn on, a panel rated at 100 amps or less, or plans to add high-draw equipment like an EV charger, hot tub, or generator transfer switch. We assess your current load during a free estimate.
What is the difference between a panel upgrade and a panel replacement?
A panel upgrade increases your electrical capacity, typically from 100 amps to 200 amps, to handle more circuits and heavier loads. A panel replacement swaps a failing, known-defective, or outdated panel for a new one at the same amperage. Both involve installing a new breaker panel.
How long does an electrical panel upgrade take?
A standard 200-amp panel upgrade is typically completed in one day, usually 6 to 8 hours. Your power will be off for most of the work. We coordinate with the utility company and schedule the inspection so you are back up and running as quickly as possible.
Do I need a permit for a panel upgrade in Northern Virginia?
Yes. Panel upgrades require an electrical permit and a follow-up inspection in every Northern Virginia jurisdiction. SparkWise handles the full permit application, coordinates with your utility for the meter disconnect, and schedules the final inspection.
How much does a panel upgrade cost?
The cost depends on your current panel size, the new capacity needed, and the condition of your existing wiring. A 200-amp upgrade in Northern Virginia generally ranges from $4,000 to $6,000. We provide a detailed written estimate after evaluating your home.

The EV Home Charger install was exceptional. The original estimate included running the conduit around the house from the breaker panel at the back. However, once onsite, the technician figured a way to run the necessary wiring through the ceiling joists of our finished basement without cutting any drywall. The install was much cleaner visually, with less exposed conduit hidden behind the landscaping. Although this was not an easier solution that took longer than expected and an extra trip for new materials, SparkWise honored the original estimate.

Professional Electrical Panel Upgrades in Northern Virginia
An outdated or undersized electrical panel is one of the most common — and most dangerous — electrical issues in older Northern Virginia homes and businesses. Signs you may need a panel upgrade include frequently tripping breakers, flickering lights, burning smells near the panel, or an inability to add new circuits for appliances and EV chargers.
SparkWise Electric’s certified electricians perform panel upgrades from 100-amp to 200-amp and 400-amp services, depending on your home’s needs. We handle everything from pulling permits to coordinating the utility disconnect and reconnect, ensuring your upgrade meets all local code requirements.
A panel upgrade not only improves safety — it also adds value to your property, accommodates modern energy demands, and gives you the capacity for future additions like solar panels or whole-home generators. We serve homeowners and businesses throughout Fairfax, Loudoun, Prince William, and Arlington counties.
Not sure if you need a panel upgrade?
SparkWise Electric will inspect your existing panel, walk through any safety concerns (Federal Pacific, Zinsco, undersized service), and provide a clear scope and quote at no charge.

Planning new high-draw equipment after a panel upgrade? Consider a dedicated circuit installation service covers proper circuit sizing, permits, and inspection for EV chargers, hot tubs, and major appliances.
An electrical panel upgrade increases your home’s electrical capacity and replaces an aging or unsafe panel with a modern one. The right service size depends on your square footage, current and planned loads (HVAC, EV charger, kitchen, generator), and the condition of your existing panel and service entrance.
100-amp vs. 200-amp vs. 400-amp service
100-amp: common in older or smaller homes; often undersized once you add an EV charger, electric range, or modern HVAC.
200-amp: the most common upgrade for today’s single-family homes; comfortably handles central HVAC, EV charging, and several large appliances.
400-amp: larger homes, additions, or properties planning solar, battery storage, or multiple high-draw systems.
What affects the cost of an electrical panel upgrade?
Cost varies with the service size, whether the meter base and service entrance need replacement, panel location and accessibility, the number of circuits, and any code-required corrections (grounding, bonding, AFCI/GFCI). Permit and inspection fees and the utility disconnect and reconnect also factor in. Requirements vary by jurisdiction and your local Authority Having Jurisdiction (AHJ), so we confirm the scope and provide a clear, itemized quote before any work begins.
Upgrading your panel capacity is the ideal time to add whole-house surge protection to safeguard your home’s electronics, appliances, and EV charging equipment.
SparkWise Electric has completed more than 60 panel replacements, heavy-ups, and sub-panel installations across Northern Virginia — Arlington, Alexandria, Springfield, Woodbridge, Fairfax, Vienna, Reston, Sterling, Great Falls, McLean, Falls Church, Burke, Lorton, Centreville, Leesburg, Ashburn, Aldie, Manassas Park, Stafford and the surrounding area.
Most of them started the same way: the homeowner wanted something else. An EV charger, a hot tub, a kitchen remodel, a heat pump. The panel came up because there was no room left in it, or because opening it revealed a problem nobody knew was there.

What Actually Sends People to Us
These are real situations from our own job records, anonymized. They are the four patterns we see most.
The panel is running hot. A Falls Church homeowner called because the main panel tripped whenever both furnaces ran at once, and the panel board felt warm to the touch. Warm is not normal. Warm means a connection is making resistance where it should be making contact.
The panel already failed. A Fairfax client was referred to us for a full replacement after the existing panel burned from overheating. By that point the question is not whether to upgrade — it is how fast we can get a permit and a service disconnect scheduled.
A home inspection turned up a Federal Pacific panel. One Fairfax buyer closed on a house and discovered a 1960s Federal Pacific inside. A Reston client had the same panel and had us replace it with a Square D QO load center. More on why below.
There is simply no space. This is the quiet majority. The panel works, but every slot is full, and the EV charger, hot tub, or new range circuit has nowhere to land.
Federal Pacific and Zinsco: Why We Replace Them on Sight
Federal Pacific Stab-Lok and Zinsco panels were installed widely in homes built roughly between the 1950s and early 1980s, and Northern Virginia has plenty of that housing stock. The concern with both is documented breaker failure — breakers that do not always trip when they should. A breaker that does not trip is a breaker that is not protecting the wire behind it.
We do not add circuits to these panels and we do not attempt repairs on them. If you have one, replacement is the recommendation, and it is not a close call. If you are not sure what you have, an electrical safety inspection will tell you in about an hour.
100A, 150A, 200A — What Size You Actually Need
The right answer comes from a load calculation, not from a rule of thumb. That said, here is what we install and why.
200A is the standard for most Northern Virginia single-family homes today, and it is what we install in the large majority of full replacements. It leaves headroom for an EV charger, a heat pump, an induction range, and a future addition without a second upgrade.
150A shows up constantly as the existing service in homes built in the 1960s through 1980s. A large share of our heavy-ups are a 150A panelboard demo and replacement.
100A still makes sense for smaller homes, townhouses, and condos where the calculated load genuinely fits, and for detached structures fed from the main house.
Commercial three-phase is a different conversation — we have installed 125A and 225A main-lug three-phase panels in Tysons and McLean. See commercial panel upgrades.
A load calculation accounts for square footage, heating and cooling equipment, appliances, and anything you plan to add. It is a code requirement, not paperwork we invented, and it is the difference between a panel that fits your house and a panel that fits a guess.
What the Work Actually Involves
A panel replacement is not a breaker swap. Here is the honest scope.
Exterior meter and emergency disconnect — part of the service side of a heavy-up.
Permit first. We pull it before we touch anything.
Power off at the utility. A service disconnect and reconnect has to be coordinated with Dominion, and that scheduling drives the calendar more than our own does.
Service equipment, not just the panel. Depending on the house this can include a new meter base, a riser or service mast, and new service-entrance conductors. We have done 200A NEMA 3R meter bases on underground service in Great Falls and Sterling, an overhead 200A mast assembly in Alexandria, and a riser extension in Alexandria where the existing one was too short to be compliant.
Grounding and bonding. This is the part that fails inspections. Ground rods, water-pipe bonding, and the neutral-to-ground separation in any sub-panel all get corrected to current code, even if the old install predated the requirement.
Circuit transfer and labeling. Every circuit gets moved, landed, and labeled. Some need to be extended to reach the new enclosure.
Inspection. We meet the inspector. You do not have to be there for it if that is easier.
Most residential replacements are a one-day job on site. The permit and the utility coordination are what stretch the overall timeline.
Permits and Inspections, by Jurisdiction
Every panel replacement in Northern Virginia requires a permit and an inspection. There is no version of this that is legitimately permit-optional, and an unpermitted panel is a problem that surfaces at resale.
Fairfax County — filed through the PLUS portal as Residential Electrical. Addresses inside the City of Fairfax go through the city's own process.
Loudoun County — filed through LandMARC as Electrical (Residential) – Alteration.
Prince William County — filed through the ePortal as Electrical Residential Alteration & Repair.
Arlington County — its own permit system, separate from the Fairfax process.
Alexandria, Falls Church, Manassas and Manassas Park are independent cities and each runs its own permitting.
Stafford, Fredericksburg and King George each run their own portals as well.
We hold active accounts in each of these systems and file under our own license. Requirements do change, so we confirm current rules with the authority having jurisdiction on every job rather than assuming last year's process still applies.
Sub-Panel or Full Heavy-Up?
Not every space problem needs a new service. Sub-panels are a large share of our panel work — we have installed them in Arlington, Alexandria, Springfield, Sterling, Leesburg, Ashburn, Lorton and Stafford.
A sub-panel is the right answer when your main service has enough capacity but you need circuits somewhere else — a finished basement, a garage, a detached shed or workshop, an addition. It is faster and less expensive than a service upgrade.
A full heavy-up is the right answer when the load calculation says the existing service is genuinely undersized, when the panel is a known-defective brand, or when the service equipment itself is at end of life. If you are adding an EV charger specifically, panel upgrades for EV charging covers the load-management options that sometimes let you avoid the upgrade entirely.
What It Costs
We quote from the actual house, not from a table, because the variables are real: whether the service is overhead or underground, whether the meter base and riser need replacing, whether the panel is moving to a new location, how many circuits need extending, and what the local permit fee is.
What we can tell you is what drives the number up. A straight panel-for-panel replacement in the same location, on an existing service, is the low end. Add a new meter base, a mast or riser, a relocation, or a service size increase and each one moves the price. We put all of it in writing before we start, and we do not discover new charges mid-job.
Panel Upgrade FAQ
How long will my power be off? Typically most of a working day. We coordinate the disconnect and reconnect with the utility and work to keep the outage inside a single visit.
Do I need to be home? For the start of the job, yes, so we can get to the panel. For the inspection, no — we meet the inspector.
Will a new panel lower my electric bill? No, and anyone who tells you otherwise is selling. A panel distributes power; it does not reduce consumption. It makes the house safer and makes new circuits possible.
Can you just add a sub-panel instead? Sometimes, and we will tell you when that is the better answer. It depends on what the load calculation shows.
What about surge protection? A panel replacement is the natural moment to add it, since the device mounts at the panel. See whole-house surge protection.
Do you handle generator connections? Yes — see generator transfer switches. We have installed interlocks and transfer switches alongside panel work on a number of jobs.
