Electrical problems don't wait, and neither do we, so we keep our schedule flexible enough to get to your home or business when the problem is fresh. Dead outlets, flickering lights, a breaker that keeps tripping, a light switch that stopped working, a GFCI that will not reset. These are the calls we handle every day, and we approach each one the same way: find the root cause, not just the symptom.
A tripping breaker might point to an overloaded circuit, a failing breaker, or a wiring fault deeper in the wall. A flickering light might be a loose connection at the fixture or a problem at the panel. We run through the diagnostics carefully so the fix sticks. Where code calls for GFCI or AFCI protection, we install it as part of a code-compliant repair rather than patching around it.
You get straight answers about your panel and wiring, no surprises, and a clear explanation of what we found and what we did. We make the fix and leave it tidy.
Before a small wiring issue turns into a hazard, it is worth knowing whether your panel has the capacity to handle the load you are putting on it. Older homes in the area often came with 60- or 100-amp service and fuse boxes that were never designed for today's appliances, home offices, and EV chargers. When the panel can no longer keep up, the answer is an upgrade.
We handle the full range of service work: panel replacement, 200-amp upgrades, fuse-to-breaker conversions, subpanel installation, and service-entrance upgrades at the meter. Before we recommend anything, we do the load calculation so the new panel actually fits your needs. If you are adding a major appliance, finishing a basement, building an addition, or planning a kitchen renovation, that is also the right time to add dedicated circuits for a dryer, range, or workshop.
The wiring done right the first time means fewer callbacks and no rework down the road. Leave the breakers to us.
Our electricians know the homes and wiring in this area, which makes a difference when you are adding outlets to a mid-century split-level or running a new circuit to a finished basement. We install and replace outlets of all types, including GFCI outlets in kitchens, bathrooms, garages, and outdoor locations where code requires them. Dimmer switches, smart switches, and standard replacements are all straightforward work we do on a regular basis.
For lighting, we install recessed and LED fixtures, under-cabinet kitchen lighting, bathroom and vanity lighting, and exterior fixtures including motion sensor lights and security lighting. Outdoor and security lighting is a common request from both homeowners and landlords who want better coverage around their property. Ceiling fan installation and replacement rounds out the list, including wiring a new fan where no ceiling box currently exists.
We are ready to get your circuits working again.
Older homes across Prince George's County carry a lot of history in their walls, and sometimes that history includes wiring that no longer meets code or no longer meets the demands of a modern household. Whole-home rewiring, code-violation repairs, and failed-inspection corrections are work we handle regularly for homeowners, sellers, and landlords getting units ready for occupancy.
If a home inspection turned up code violations, or a permit was pulled and the work did not pass, we come in and make it right. That includes grounding and bonding corrections, smoke detector and carbon monoxide detector installation, and any wiring that needs to be brought up to current Maryland electrical code. An electrical safety inspection is a natural starting point if you are buying an older home, planning a renovation, or preparing a property for sale and want to know what you are dealing with before a buyer's inspector does.
Pick up the phone and we'll handle the wiring.
Calverton and the surrounding Prince George's County communities include some of the oldest housing stock in the region. That history, combined with Maryland's weather and the area's rapid EV adoption, shapes which electrical upgrades come up most often in our schedule.
Knob-and-tube wiring was standard in homes built before the 1950s, and aluminum branch wiring was common in homes built through the 1970s. Both systems are still present in a significant number of mid-century homes in this part of Maryland. Knob-and-tube has no ground wire and degrades over time, creating both safety concerns and insurance complications. Aluminum branch wiring expands and contracts with temperature changes, which can loosen connections and create arc and heat hazards at outlets and switches.
We assess what is in the walls, explain what we find, and handle the remediation or full rewiring based on the scope of the problem. For some homes, targeted aluminum wiring remediation with proper connectors and devices resolves the issue. For others, a whole-home rewire is the right call. We walk you through the options before any work begins.
Maryland has one of the highest rates of electric vehicle ownership in the country, and the DC metro commuter corridor runs right through this part of Prince George's County. A Level 2 home charger is the practical choice for daily charging, and it requires a dedicated 240-volt circuit sized to the charger and the vehicle.
Before we run the circuit, we check panel capacity to confirm the existing service can carry the added load. If it cannot, we handle the panel work first. We install Level 2 EVSE for Tesla and all other EV brands, and we pull the permit when required so the installation is on record.
Nor'easters, summer thunderstorms, and the occasional ice storm knock out power across Maryland every year. A standby generator is the answer for homeowners and businesses that cannot afford to be without power for days at a time. Our work covers the electrical side: running the generator wiring, installing the transfer switch, and integrating everything with the existing panel so the switchover is safe and automatic.
A properly wired transfer switch is not optional. It protects utility workers from backfeed and protects your equipment from a sudden return of grid power. We size the circuits to match the generator and the loads you need covered, and we do it to code.
Scheduling a service call is simple, and we work with all types of customers across the area. Homeowners call us for repairs, upgrades, and renovation wiring. Landlords and property managers call us to get units up to code, add circuits, and handle the electrical punch list before a new tenant moves in. Small businesses, apartment buildings, and light commercial properties are a regular part of our schedule as well.
When you call us, you talk to the people who actually show up. We treat your home and its wiring the way we would our own, which means we work carefully, communicate clearly, and do not leave a job half-finished.
We handle basement wiring, garage circuits, workshop subpanels, kitchen and bathroom remodel wiring, home addition circuits, and new construction rough-in. Whatever the project, we scope it honestly and get it done. We're ready to get your circuits working again.

We are based in Calverton and regularly serve Beltsville, Adelphi, Langley Park, Hyattsville, College Park, Greenbelt, Laurel, Bowie, and Lanham. If you are in the area and unsure whether we cover your location, call (227) 294-9289 and we will let you know.
Do not use the outlet or the circuit and do not attempt to reset the breaker yourself if the panel is making noise or feels warm. Turn off the affected circuit at the breaker if you can do so safely, and call us at (227) 294-9289. These are signs of a wiring fault or failing component that needs attention right away.
A partial power loss usually points to a tripped breaker, a failing breaker, or a problem at the service entrance. Check your panel for a breaker that has moved to the middle position and reset it once. If it trips again immediately, or if the panel itself looks or smells unusual, leave it alone and call us. We will diagnose the cause and make the repair.
Repeatedly tripping breakers in a kitchen usually mean the circuit is overloaded, a breaker is failing, or a dedicated circuit is needed for a high-draw appliance. We troubleshoot the cause rather than just reset the breaker, and we can add a dedicated circuit if the existing wiring is undersized for the load. Call (227) 294-9289 and we will get it sorted out.
Yes. We are available every day, including weekends, from 9:00 AM to 11:00 PM. If a Saturday or Sunday is the only time that works for you, we can schedule it. Call (227) 294-9289 to set something up.
We give you a quote before any work begins. The price covers the job as scoped, and we do not add line items at the end of the visit. If we find something additional once we are on-site, we explain it and get your approval before proceeding.

How do I know if my panel needs to be upgraded?
A few signs point clearly to a panel that has reached its limit: breakers that trip under normal household loads, a fuse box that has never been replaced, lights that dim when a large appliance kicks on, or no room to add circuits for new equipment. Homes with 60- or 100-amp service that now carry home offices, EV chargers, or modern appliances are often undersized. We do a load calculation before recommending any upgrade so you know exactly what the panel needs to handle.
What causes a breaker to keep tripping?
A breaker that trips repeatedly is usually telling you one of three things: the circuit is carrying more load than it was designed for, the breaker itself is failing and no longer holds its rating reliably, or there is a wiring fault somewhere on the circuit. Resetting a breaker that immediately trips again is a sign to stop and call us. We trace the cause rather than just reset the device, because a failing breaker or wiring fault does not fix itself.
Is the work permitted and inspected?
We pull permits when the work requires them under Maryland code, which includes panel replacements, service upgrades, new circuit installations, and EV charger hookups. Permitted work is inspected by the local authority and goes on record, which matters when you sell the property or make an insurance claim. We will tell you upfront whether a permit is required for your job.
Same-Day and After-Hours Availability
Electrical problems do not follow a schedule, and we keep our availability flexible so you are not waiting days for service. Same-day and after-hours calls are part of how we operate.
My home was built in the 1950s or 1960s. Is the wiring safe?
It depends on what is in the walls. Homes from that era often have knob-and-tube wiring, which has no ground wire and degrades over time. Homes built through the 1970s may have aluminum branch wiring, which can loosen at connections and create heat hazards. Neither system is automatically a crisis, but both warrant a professional assessment. We look at what is present, explain what we find, and give you honest options before any work begins.
What does a Level 2 EV charger installation involve?
A Level 2 charger runs on a dedicated 240-volt circuit sized to the charger and the vehicle. Before we run any wire, we check your panel to confirm it has the capacity to carry the added load. If it does not, we handle the panel work first. We install EVSE for Tesla and all other EV brands, and we pull the permit when required so the installation is documented. Most residential installations are completed in a single visit.
How does backup generator wiring work?
Our work covers the electrical side of a generator installation: running the generator wiring, installing the transfer switch, and connecting everything to the existing panel. A transfer switch is required by code. It isolates your home from the grid when the generator is running, which protects utility workers from backfeed and protects your equipment when grid power returns. We size the circuits to match the generator and the loads you need covered.
Work Performed by Licensed Electricians
Every job on this list is handled by licensed electricians who know the code requirements for Maryland and the wiring common to homes in this part of Prince George's County.
Do I need to be home while the work is done?
For most jobs, yes. We need access to the panel, the work area, and any rooms where circuits or outlets are being added or repaired. If you are a landlord scheduling work at a rental unit, we can coordinate with a tenant or property manager as long as someone with access is present. We will confirm the access requirements when you call to schedule.
How does pricing work, and will the quote change after the electrician arrives?
We give you a quote before any work begins. The price covers the job as scoped, and we do not add line items at the end of the visit. If we find something additional once we are on-site, we explain it and get your approval before proceeding. You will not be handed a bill that is different from what you agreed to.
Upfront Quotes With No Surprise Fees
We quote the job before we start and stick to it. If something unexpected comes up on-site, we explain it and get your approval before any additional work begins.
Is same-day service available?
Same-day availability is part of how we operate. When our schedule allows, we can get to you the same day you call. We also offer after-hours service for situations that cannot wait. For urgent issues like sparking outlets, a buzzing panel, or a breaker that will not hold, call us and we will tell you exactly when we can be there.
What does it mean if my outlets feel warm or make a buzzing sound?
A warm or buzzing outlet is a sign of a wiring fault, a failing device, or a connection that has loosened over time. These are not symptoms to monitor. Stop using the outlet, do not plug anything into it, and call us. If the outlet is also discolored or has a burning smell, turn off the circuit at the breaker if you can do so safely before calling.
What is whole-home surge protection and is it worth it?
A whole-home surge protector installs at the panel and intercepts voltage spikes before they reach your outlets and equipment. It covers surges that come in from the utility line and surges that originate inside the home from large appliances cycling on and off. For homes with computers, smart appliances, and entertainment systems, it is a practical layer of protection. We install the device as part of a panel visit or as a standalone job.
Every job is different, and the best way to get an accurate answer for your situation is to call us directly. Reach us at (227) 294-9289 and we will walk you through what the work involves and what it will cost.
