Flickering lights fixed. Dead outlets revived. Power back on.
When the lights start dimming, an outlet goes dead, or a breaker trips and won't reset, you need answers fast. Frederick Electrical Company handles the full range of residential and commercial electrical work in Frederick, MD, from quick repairs to full rewiring projects. We serve homeowners, landlords, property managers, and business owners throughout the area, and we're open every day from 5:30 AM to 9:00 PM, including weekends.
Whether it's a single dead outlet or a panel that's overdue for replacement, call (240) 269-2329 for a quote and we'll get it on the schedule.
We bring prompt response, even for last-minute electrical calls, so you're not waiting around when something goes wrong.
Seeing flickering lights or a warm outlet? Those are the kinds of symptoms that point to something worth looking at before it becomes a bigger problem.
The calls we get most often come from people dealing with one of these situations:
Each of these symptoms can have more than one cause. A dead outlet might be a tripped GFCI on a shared circuit. Flickering lights in one room often point to a loose connection. Whole-house dimming or a breaker that won't hold can mean a wiring fault or an overloaded panel. We don't guess at the answer. Working here means getting the diagnosis right before the work starts.
GFCI and AFCI protection failures are behind more "dead outlet" calls than most people expect. We check the circuit from the source, confirm what's causing the problem, and explain it clearly before any work begins. Clear communication from the first call to the final test is how a repair should go. We'll trace it, fix it, and test it before we leave.
Electrical problems don't wait, and neither do we, especially when the panel itself is the source of the trouble.
Older panels, undersized service, and fuse boxes that were never meant to carry a modern electrical load are common in Frederick's housing stock. We handle:
Landlords managing multi-unit properties and small businesses expanding their space often find that the existing panel simply can't carry the added load. We size the work to what the property actually needs, and all panel and wiring work is finished to code. Call us and we'll walk you through the fix.
Arc-fault and ground-fault breakers are part of the upgrade conversation too. Newer code requirements call for AFCI protection in living spaces and GFCI protection in wet areas, and a panel replacement is the right time to bring those up to current standards.
Wiring a home right takes the right tools and a careful hand, whether the job is a single outlet swap or a full lighting overhaul across multiple rooms.
We install and replace outlets and switches throughout residential and commercial properties. Common jobs include:
Lighting work covers everything from a single fixture swap to a full recessed lighting layout in a finished basement. We handle:
Lighting upgrades often pair with a dedicated circuit or a panel capacity check, especially when adding multiple fixtures to a space that wasn't wired for the extra load. We'll get your lights back on fast.
Scheduling a service call is simple, and so is the reason most appliance circuits get added: shared circuits get overloaded, breakers trip, and appliances wear out faster than they should.
A dedicated circuit gives a single appliance or piece of equipment its own path back to the panel, which keeps the load balanced and reduces the risk of nuisance tripping. We install dedicated circuits for:
When adding circuits to an older home, we sometimes find that the existing wiring can't support the added load without upgrades elsewhere. We scope that out on the visit and explain what's needed before any work starts. The wiring done properly, start to finish, is what protects both the appliances and the home.
Frederick County's housing stock and regional conditions create a specific set of electrical needs that come up regularly. These three services account for a large share of the upgrade calls we receive.
Frederick has a significant number of older homes, many built during periods when knob-and-tube wiring and early aluminum branch-circuit wiring were standard practice. Both systems carry limitations that affect safety and insurability. Knob-and-tube wiring lacks a ground conductor, and its cloth insulation deteriorates over time. Aluminum branch wiring expands and contracts with heat cycles, which can loosen connections and create fire risk at outlets and fixtures.
Replacing these systems involves running modern copper wiring, updating circuits to current capacity, and bringing outlets and panels in line with present standards. Insurers and home buyers increasingly flag knob-and-tube and aluminum wiring during transactions. An inspection call is the right first step to understand what the property has and what the work involves.
Frederick County residents commuting to Washington D.C., Bethesda, and the Northern Virginia corridors are among the fastest-growing EV adopter groups in Maryland. A Level 2 home charger cuts overnight charging time significantly compared to a standard 120V outlet, and it requires a dedicated 240V circuit sized to the charger and the panel's available capacity.
We handle the full electrical side of EV charger installation: the dedicated circuit, the 240V outlet or hardwired connection, and the panel load calculation to confirm the service can carry the added draw. This applies to both residential installs and small commercial properties adding charging for employees or customers.
Frederick County sits in a region that sees nor'easters, ice storms, and summer thunderstorms capable of knocking out power for days at a time. A standby or portable generator connected through a proper transfer switch keeps essential circuits running when the grid goes down.
We handle the electrical side of generator hookups: the transfer switch installation, the generator circuit wiring, and the panel integration that routes power safely during an outage. A transfer switch is not optional, it's what prevents backfeed onto utility lines and keeps the system safe. We scope the work to the circuits that matter most to you and confirm the panel can support the load.
Not every electrician works the same way, and not every electrical call starts with a symptom. Some of the most important calls come from people who want to know what they have before something goes wrong.
We perform:
Whole-home surge protection is part of this conversation too. A surge protector installed at the panel guards every circuit in the house against voltage spikes from lightning, utility switching, and large appliances cycling on and off. It's a straightforward addition during an inspection or panel visit.
One call is enough to get the visit booked.
We work across the full range of property types in Frederick and Frederick County. On the residential side, that includes single-family homes, condos, apartments, and rental properties. On the commercial side, we handle offices, retail spaces, small businesses, and warehouses.
Project types range from new construction wiring and home additions to basement finishing, garage conversions, and code-correction work on properties that have changed hands. Whether the property is a 1920s row house in downtown Frederick or a newer commercial build in the county, the scope of work gets confirmed on the call before anything is scheduled.
Electrical problems don't wait, and neither do we, so we've kept the scheduling process straightforward.
When you call, we go over the symptoms or the project, give you a price for the work, and confirm what that covers before the visit is booked. Ask about scope or materials and you get a straight answer. Whether you're asking about the cost to replace an outlet, install a ceiling fan, upgrade a panel, wire an EV charger, or rewire an older home, the rate is explained before anything is scheduled.
Pick the date. We do the wiring. We clean up after.
We're open every day from 5:30 AM to 9:00 PM, including Saturdays and Sundays. Prompt response, even for last-minute electrical calls, is something we take seriously because electrical problems rarely show up at a convenient time.
The electrical work we do in Frederick extends to homes and businesses throughout Frederick County and the surrounding communities. We regularly serve:
If you're in the county and outside Frederick proper, call and we'll confirm coverage for your address.
After any repair or installation, we test the affected circuit under load to confirm the fix holds. That means running the outlet, the fixture, or the appliance through normal operation and checking that the breaker stays seated and the connections stay stable. We do not call a job done until the test confirms it.
Warmth to the touch, discoloration around the face plate, a burning smell, sparking when you plug something in, or an outlet that simply stopped working are all signs worth taking seriously. Any of those symptoms can point to a wiring fault behind the wall rather than just a worn outlet, and that is worth diagnosing before the outlet is replaced.
Knob-and-tube wiring is not automatically dangerous, but it has real limitations. It lacks a ground conductor, its cloth insulation deteriorates over time, and it was not sized for modern electrical loads. Whether it needs to be replaced depends on its condition, how it has been modified over the years, and what the home's current load demands. An inspection is the right first step before any decision is made.
Aluminum branch wiring expands and contracts with heat cycles, which can loosen connections at outlets, switches, and fixtures over time. Loose connections create heat and increase fire risk. The fix is not always a full rewire. In some cases, remediation at the connection points is enough, but that depends on the scope of what is present and the condition of the wiring throughout the home.
Flickering in a single fixture usually points to a loose connection at the fixture or the switch. Dimming across a whole room or the whole house when an appliance kicks on points to a circuit or panel capacity issue. Persistent flickering that does not track to a single fixture or appliance is a reason to schedule a diagnostic visit rather than wait and see.
Older homes were wired for far lighter electrical loads than what a modern household draws. A 100-amp service and a panel with limited slots cannot carry the combination of home offices, kitchen appliances, EV chargers, and entertainment systems that most households now run at once. Repeated tripping and a shortage of outlets are both signs that the panel or the wiring may need to be upgraded rather than just reset or added to.
A burning smell from an outlet, panel, or switch, sparking that does not stop when the device is unplugged, a breaker that will not reset and leaves part of the home without power, or visible damage to wiring are all situations that warrant a call right away. We are available every day from 5:30 AM to 9:00 PM and take short-notice calls when something needs immediate attention.
Replacing a light bulb or resetting a tripped GFCI outlet is straightforward. Anything that involves opening a wall, working inside the breaker panel, running new wire, or replacing a breaker goes beyond what a homeowner should take on without knowing exactly what the circuit involves. The risk is not just to the repair itself. Wiring done incorrectly can create faults that are not visible until they cause a problem.
A transfer switch connects the generator to the home's panel and controls which circuits it powers during an outage. It also physically isolates the home from the utility line, which prevents the generator from sending power back onto the grid where it can harm utility workers restoring service. A generator wired without a proper transfer switch is a code violation and a safety hazard.
That depends on the generator's output and what the homeowner needs to keep running during an outage. Common priorities are the sump pump, the refrigerator, essential lighting, and the circuits that supply power to heating equipment. We scope the transfer switch installation to the circuits that matter most to you and confirm the panel can support the load before the work starts.
It depends on how much capacity the panel has available after accounting for existing loads. A Level 2 EV charger requires a dedicated 240-volt circuit with the correct wire gauge and breaker size. We run a load calculation on the call to give you a sense of whether the panel can handle it as-is or whether a subpanel or service upgrade is part of the conversation.
Frederick Electrical Company is available every day from 5:30 AM to 9:00 PM.
Whether the job is a tripped breaker, a panel replacement, an EV charger circuit, or a full rewiring project, call (240) 269-2329 and we'll get the scope and the price sorted out on the call.
Quick to arrive. Careful with your home. Clean when we leave.
One call is enough to get the visit booked.
We handle electrical work across the full range of what homes and businesses in Frederick need, from a single dead outlet to a panel replacement to a full rewiring project. Every job starts with a clear scope and a price confirmed before anything is scheduled. The table below lays out what each service covers, who it fits, and what is worth knowing before you call. Open every day from 5:30 AM to 9:00 PM, including weekends.
| Service | What It Covers | Best For | Things to Know |
|---|---|---|---|
| Electrical Panel Upgrades | 100-amp to 200-amp service upgrade, Fuse box to breaker panel conversion, Subpanel installation, Load calculation for added equipment | Older homes adding EV chargers, major appliances, or finishing new living space | Panel and wiring work is finished to code, and a load calculation confirms the service size before the upgrade is scoped. Undersized service is the most common reason newer equipment trips breakers from the start. |
| Whole-Home Surge Protection | Panel-level surge device installation, Protection for all downstream circuits, Pairing with panel upgrades or inspections | Homes with sensitive electronics, home offices, or equipment that is expensive to replace | A surge protector at the panel guards every circuit in the house against voltage spikes from lightning, utility switching, and large appliances cycling on and off. It is a straightforward addition during any panel visit. |
| Wiring & Circuit Installation | New circuit runs from panel to location, Home addition and basement wiring, Garage and detached structure wiring, Code-compliant wire sizing and routing | Additions, renovations, and spaces being finished or converted | Wire gauge, circuit breaker size, and routing path all depend on the load the circuit needs to carry. We size everything to what the space will actually draw. |
| Ceiling Fan Installation | Fan and light kit installation, Switch and remote wiring, Box replacement for fan-rated support, New circuit if needed | Bedrooms and living spaces adding a fan where only a light fixture exists now | Standard light fixture boxes are not rated to support a ceiling fan. We replace the box when needed so the mount is solid before the fan goes up. |
| Outlet & Switch Installation | GFCI and AFCI outlet installation, USB outlet and dimmer upgrades, 240V outlets for appliances, Switch replacement and new locations | Rooms that need more outlets, safer outlets, or modern switch controls | Kitchens, bathrooms, garages, and outdoor locations require GFCI protection under current code. A panel check is sometimes needed before adding outlets to older circuits. |
| Electrical Repairs & Troubleshooting | Flickering lights and dead outlets, Burning smells and buzzing panels, Tripped breakers and GFCI faults, Circuit tracing and diagnosis | Homeowners and renters dealing with an active electrical symptom | Many symptoms share causes. We trace the fault to the source before replacing anything, which avoids repeat calls for the same problem. |
| Code-Correction Wiring | Failed inspection follow-up, Municipal and county violation repairs, GFCI and AFCI upgrades to current standards, Grounding and bonding corrections | Properties that failed a municipal or county inspection or are changing hands | Code requirements have changed significantly over the past few decades. Older wiring that was correct when it was installed may not meet what inspectors enforce today. We identify what needs correction and explain the scope before work begins. |
| Lighting Installation | Fixture replacement and new installs, Recessed and under-cabinet lighting, Outdoor and security lighting, Motion sensor and landscape wiring | Homeowners upgrading interior lighting or adding exterior security and landscape lighting | Adding multiple fixtures to a single circuit can exceed its rated load. We check capacity before the install and add a dedicated circuit when the math calls for it. |
| Basement & Sump-Pump Circuits | Dedicated sump pump circuit, Basement finishing wiring, GFCI protection in below-grade wet areas, Panel capacity check for added load | Frederick County homeowners finishing a basement or protecting against sump pump failures during storms | A sump pump on a shared circuit can lose power at the worst moment if another load trips the breaker. A dedicated circuit keeps the pump isolated from everything else in the panel. |
| Dedicated Appliance Circuits | Refrigerator, dishwasher, and microwave circuits, Washer and dryer circuits, Workshop and shed circuits, Panel slot and capacity check | Kitchens, laundry rooms, and workshops where shared circuits cause repeated tripping | A dedicated circuit isolates a single appliance from the rest of the load on a shared circuit. It reduces nuisance tripping and protects the appliance from voltage fluctuations caused by other draws. |
| Electrical Safety Inspections | Whole-home system review, Pre-purchase buyer inspections, Rental property landlord inspections, Code violation identification | Buyers, sellers, landlords, and owners who want a current picture of what their system holds | An inspection is the right first step before any rewiring or panel decision. It tells you what the property has, what code requires, and what the work actually involves. |
| Breaker & Fuse Repair | Breaker replacement and reset, Fuse box troubleshooting, Arc-fault and ground-fault breaker work, Panel interior inspection | Homes where a breaker trips repeatedly or a fuse blows without an obvious cause | A breaker that trips repeatedly is often signaling an overloaded circuit or a wiring fault, not a bad breaker. We confirm the cause before swapping hardware. |
What are the signs that a home's electrical panel needs to be upgraded?
Breakers that trip regularly under normal loads, a panel with no open slots for new circuits, a fuse box that was never converted to breakers, and visible corrosion or heat discoloration inside the panel are all signs worth taking seriously. Homes running on 100-amp service that now carry EV chargers, home offices, and modern kitchen appliances are frequently undersized for what they are being asked to do. A load calculation on the call gives a starting picture of whether an upgrade is the right direction.
What is grounding and bonding, and why does it matter in older Frederick homes?
Grounding gives fault current a controlled path back to the panel so a breaker can trip and clear the fault. Bonding ties metal components together so they all sit at the same electrical potential, which prevents shock hazards when someone touches two metal surfaces at once. Older homes in Frederick were often wired without a ground conductor in the branch circuits, which means outlets test as ungrounded even if the panel itself is properly grounded. We identify grounding and bonding gaps during an inspection and explain the options for correcting them.
How long does a panel upgrade or full rewire typically take?
A panel replacement in a straightforward residential setting is usually a single-day job. A partial rewire covering a few circuits takes a day or two depending on access and what the walls require. A full rewire of an older home with knob-and-tube or aluminum branch wiring is a multi-day project, and the timeline depends on the size of the home, the number of circuits, and whether walls need to be opened. We scope the timeline on the call so you know what to plan for before the work starts.
Faults Traced Before Anything Is Replaced
We diagnose before we replace. When a symptom has more than one possible cause, we trace the circuit to the source and confirm what is actually wrong before any parts are ordered or swapped.
What does a Level 2 EV charger installation involve on the electrical side?
A Level 2 charger runs on a dedicated 240-volt circuit sized to the charger's output rating. That means a new circuit run from the panel to the garage or parking location, the correct wire gauge for the amperage, and either a 240-volt outlet or a hardwired connection depending on the charger. We also run a load calculation to confirm the panel has the capacity to carry the added draw without affecting other circuits. If the panel is already at or near its limit, a subpanel or service upgrade is part of the conversation.
How is a standby or portable generator connected to a home's electrical system?
The connection goes through a transfer switch, which is installed between the generator and the panel. The transfer switch controls which circuits the generator powers and physically isolates the home from the utility line during an outage. That isolation step is what prevents power from feeding back onto the grid, which is a serious hazard for utility workers restoring service. We scope the transfer switch installation to the circuits that matter most, confirm the panel can support the generator's output, and make sure the wiring meets what the installation requires.
Do I need to be home while electrical work is being done?
For most jobs, yes. Access to the panel, the affected circuits, and the areas being worked on is part of what makes the job go smoothly. If the scope is limited to an exterior location or a detached structure, we can sometimes work through the details on the call. For any job that involves the main panel or interior wiring, having someone on site who can answer questions and confirm access to all areas keeps the visit on track.
Scope Agreed Before the Panel Is Opened
The price and the scope of the work are confirmed on the call before the visit is booked. You know what the job covers before anyone shows up at your door.
What is GFCI protection and where is it required?
A GFCI outlet or breaker monitors the current flowing through a circuit and trips within milliseconds if it detects an imbalance, which is the signature of current taking an unintended path through a person or a wet surface. Current code requires GFCI protection in kitchens, bathrooms, garages, unfinished basements, outdoor locations, and anywhere near a sink or water source. Older homes in Frederick often have these areas wired without GFCI protection because the requirement did not exist when the home was built. Bringing those locations up to current standards is a straightforward part of an inspection or outlet replacement visit.
What does a warm or buzzing outlet usually mean?
Warmth at an outlet face means current is generating heat somewhere in the connection, which points to a loose wire, a failing device, or a circuit that is carrying more load than it was sized for. A buzzing sound from an outlet or a switch usually means arcing at a loose connection. Both are symptoms that get worse over time rather than better. Either one is worth a diagnostic call rather than a wait-and-see approach, because the underlying cause does not resolve on its own.
Older and Newer Wiring Both Handled
From knob-and-tube and aluminum branch wiring in Frederick's older housing stock to modern panel upgrades and EV charger circuits, we work across the full range of what this area's homes actually have.
Is a home ready for added electrical load before a major renovation or addition?
That depends on the existing panel size, how many open slots it has, and what the current load already draws. A 100-amp panel with no open slots and a full load is not in a position to absorb a kitchen renovation, a finished basement, and an EV charger without some upstream work first. A load calculation on the call gives a starting picture of where the panel sits relative to what the project needs. We scope the electrical side of the addition alongside the renovation work so the panel and the new circuits are sized together.
How do emergency electrical calls work?
We are available every day from 5:30 AM to 9:00 PM and take short-notice calls when something needs immediate attention. A burning smell from an outlet or panel, sparking that does not stop when the device is unplugged, a breaker that will not reset and leaves part of the home without power, or visible damage to wiring are all situations that warrant a call right away rather than waiting for a scheduled visit. Call us and we will walk you through what to do until we can get there.
What is the difference between a subpanel and a service upgrade?
A service upgrade increases the total amperage coming into the home from the utility, which raises the ceiling on how much load the electrical system can carry overall. A subpanel draws from the existing service and distributes circuits to a specific area, like a garage, a workshop, or a finished basement, without changing the total capacity at the meter. If the main service is already sized correctly but a remote location needs its own circuits, a subpanel is usually the right answer. If the whole home is running on undersized service, a service upgrade addresses the root of the problem.
