We are available every day from 7:30 AM to 8:00 PM, so you can reach us on weekdays, weekends, and any day in between. Simple booking. Clear pricing. Safe, solid wiring. Call for a quote and we will walk through the scope with you on the phone. We'll find the fault and fix it right.
Dealing with a tripping breaker or a dead outlet? These are the calls we get most often, and they almost always point to something specific once we look. A breaker that keeps tripping, lights that flicker, outlets with no power, a burning smell near a switch, or a buzzing sound from the panel are all signs that something in the circuit needs attention.
When we visit, we trace the fault from the symptom back to the source. That might mean checking GFCI and AFCI protection, testing the circuit under load, or inspecting the wiring behind an outlet or switch. We explain what we find before any work starts, so you know exactly what the problem is and what fixing it involves.
Sparking outlets and burning smells are situations where waiting is not a good idea. Call us and we will get it diagnosed. Reach out and we'll get it diagnosed.
Calling an electrician doesn't have to be stressful, and that goes double for panel work. A breaker that will not reset, a fuse box that keeps blowing, or a panel that buzzes or runs warm are all reasons to have the panel looked at. We handle breaker repairs, full panel replacements, and service upgrades from 100-amp to 200-amp service.
Older homes in Montgomery County frequently carry panels that were sized for a lighter electrical load than modern households put on them. A load calculation tells us whether the existing service can handle what you are running, and whether an upgrade makes sense before adding circuits for a new appliance, an addition, or a detached garage. We also install subpanels for garages, outbuildings, and finished basements where running everything back to the main panel is not practical.
All panel and wiring work is finished to code, and estimates are no-pressure and priced up front before anything is scheduled.
For residential and commercial electrical work alike, outlet and switch jobs are some of the most straightforward work we do, and some of the most useful. We install and replace standard outlets, GFCI outlets in kitchens, bathrooms, and outdoor locations, AFCI breakers for bedroom and living-area circuits, dimmer switches, and weatherproof outdoor outlets.
Dedicated circuits are a separate category worth understanding. A dryer, range, dishwasher, refrigerator, or microwave each draws enough current that sharing a circuit with other loads creates problems over time. We run dedicated 240-volt and 120-volt circuits sized for the appliance, whether it is a kitchen remodel, a basement finishing project, or a new laundry hookup.
Deck wiring, shed circuits, and garage outlets all fall into this category too. Dead outlets usually have a simple cause worth finding.
Seeing flickering lights or a warm outlet? Lighting problems sometimes trace back to the fixture, and sometimes to the circuit feeding it. We install and replace light fixtures throughout the home, including recessed LED lighting, under-cabinet lighting, bathroom vanity lights, and exterior fixtures.
For outdoor work, we handle security lighting, motion-sensor lights, and landscape lighting wiring. These are practical additions for any property where visibility and security matter after dark. Commercial spaces, including offices, retail locations, and warehouses, often need lighting work that goes beyond a simple fixture swap, and we handle that scope as well.
Ceiling fan installation is a common request, especially when an existing light box needs upgrading to carry the fan's weight and load. We make the fix and leave it tidy.
Older wiring is one of the most common issues we see in this area. Full home rewiring, wiring for additions and remodels, and new construction rough-in all fall within what we do. When a kitchen remodel or basement finishing project requires new circuits, we handle the rough-in and finish wiring so the job passes inspection.
Whole-home surge protection is a natural companion to rewiring and panel work. A surge protector installed at the panel catches voltage spikes before they reach your appliances and electronics. It is a single installation that covers every circuit in the house.
Electrical work done to the standard the next inspection expects is how we approach every job, whether it is a single new circuit or a complete rewiring of a home.
Inspections come up in a few different situations. A home purchase inspection may flag wiring concerns that need a follow-up electrical evaluation. Rental properties in Montgomery County require that the electrical system is in sound condition, and landlords and property managers often need code violations corrected before a lease or a renewal. We work with homeowners, landlords, and property managers on all of it.
A safety inspection covers the panel, the branch circuits, grounding and bonding, outlet condition, and any visible wiring concerns. If there are code violations, we scope the correction work and explain what it involves before anything starts.
We show up, and we keep you posted until the job is done. That matters whether you are a homeowner waiting on a repair or a property manager coordinating access for a tenant. We'll find the fault and fix it right.
We work across the full range of property types in Calverton. Homeowners, landlords, property managers, and business owners all call us for electrical work, and the scope varies from a single outlet to a full commercial panel upgrade.
Single-family homes, townhomes, condos, and multi-unit properties all come with their own electrical considerations. We handle everything from routine repairs to complete rewiring, and we are familiar with the housing stock in this part of Maryland.
Offices, retail spaces, restaurants, and warehouses have different load demands than residential properties. We handle commercial wiring, panel work, lighting installation, and dedicated circuits for commercial equipment. No-pressure estimates, priced up front, so you know what the job costs before committing.
We serve Calverton and the surrounding communities across Montgomery County, including Burtonsville, Spencerville, Colesville, White Oak, Silver Spring, and Beltsville. Residential wiring. Commercial wiring. One number for both.
Montgomery County's housing stock includes some of the oldest homes in the Mid-Atlantic, and the region's weather and transportation trends create specific electrical needs that come up regularly here. The following services reflect what we actually see most often on Calverton properties.
Knob-and-tube wiring and aluminum branch wiring show up regularly in older Calverton homes, and both create real problems when paired with modern electrical loads. Knob-and-tube was never designed for today's demand, and aluminum branch wiring expands and contracts in ways that loosen connections over time. We identify the existing wiring type, scope the replacement, and run new copper branch circuits to bring the home up to current standards. This is among the most common rewiring jobs we handle in this part of Montgomery County.
EV adoption in the DC metro area and Montgomery County is among the highest in the country, and a Level 2 home charger is the practical choice for daily charging. Installing one requires a dedicated 240-volt circuit and, depending on the panel, a capacity review to confirm it can handle the added load. We assess the panel, run the circuit, and mount and connect the charger. If a panel upgrade is needed first, we scope that as part of the same call.
Nor'easters and ice storms bring power outages to this part of Maryland with enough regularity that generator hookups are a practical investment for both homeowners and businesses. We install transfer switches, run the generator wiring, and integrate the connection into the existing panel. A properly wired transfer switch keeps the generator isolated from the utility line, which matters for safety and for the utility's requirements.
When you call, you get the price on the phone before anything is scheduled. We go over the scope of the work, confirm what the job involves, and give you a clear number. There is no pressure to commit on the call.
We are available every day from 7:30 AM to 8:00 PM, including weekends. Short-notice scheduling is often possible, and a call will confirm what the calendar has open. Ask what it covers and you get a straight answer. We make the fix and leave it tidy.
A Level 2 charger typically requires a dedicated 240-volt, 50-amp circuit, and whether your panel can support it depends on the current load and the service size. We do a load calculation as part of every EV charger quote to confirm the panel has the capacity before any wire is pulled. If an upgrade is needed first, we scope that as part of the same call.
Breakers that trip repeatedly under normal loads, a panel that buzzes or runs warm, circuits that cannot support a new appliance, and a service size of 100 amps or less in a modern household are all signs worth having assessed. Older panels in Montgomery County homes were often sized for a lighter load than modern households put on them. A load calculation tells us whether an upgrade makes sense before any work is scheduled.
Knob-and-tube wiring lacks a ground conductor and was not designed for the loads a modern home puts on a circuit. Aluminum branch wiring expands and contracts at connection points, which loosens them over time. Whether replacement is the right answer depends on the condition of the existing wiring, the loads being put on it, and what an inspection finds. We assess the scope on the call and explain what the job involves before anything starts.
Additional charges come up when the scope changes once the work is underway, typically because the wall or panel revealed a condition that was not visible during the initial assessment. We stop and explain what we found before any additional work proceeds, and the price for that work is confirmed before we continue. Nothing is added to the scope without your agreement.
A breaker trips when a circuit is carrying more current than it is rated for, which can be caused by too many devices on a shared circuit, a failing appliance, or a wiring fault. A breaker that trips repeatedly under normal loads, will not reset, or trips immediately after being reset points to something beyond a simple overload. That is a situation worth having diagnosed rather than reset and ignored.
A burning smell near an outlet usually means a connection has loosened and is arcing, or a device has failed in a way that is generating heat. Near a panel, it can indicate a breaker that is failing to trip under a fault condition. Both are situations where the circuit should be taken out of service and the fault diagnosed before the outlet or panel is used again.
GFCI protection is required in kitchens, bathrooms, garages, outdoor locations, and anywhere an outlet is near a water source. AFCI protection is required on bedroom circuits and, under current code, on most living-area circuits in new construction and significant renovations. Whether your existing outlets need upgrading depends on when the home was built and what work has been done since. We check both as part of any troubleshooting or inspection visit.
A surge protector installed at the main panel catches large voltage spikes before they travel through the branch circuits to your appliances and electronics. A power strip handles small surges at a single outlet. Panel-mounted surge protection handles the transient events that come in through the service entrance, the kind that arrive during a storm or a grid switching event. For homes with sensitive electronics, medical equipment, or a home office, it is a straightforward addition to any panel visit.
A full rewire is usually the answer when the existing wiring is knob-and-tube throughout, when the wiring has degraded to the point where individual circuit repairs are no longer practical, or when a renovation is opening enough walls to make a full replacement efficient. Partial rewiring addresses specific circuits or areas, such as aluminum branch-circuit remediation or a kitchen remodel, where the rest of the home's wiring is in acceptable condition. We assess the scope during the inspection and explain which approach fits the situation.
Once the work is complete, we test the circuit under operating conditions. Outlets are checked for correct polarity and grounding, GFCI and AFCI devices are tested for proper function, and breakers are confirmed to be correctly sized for the circuit. If the job required a permit, the inspection is the final check, and the work is done to the standard that inspection will apply.
We are available every day from 7:30 AM to 8:00 PM, and short-notice calls are handled based on what the schedule allows. Sparking outlets, a panel that will not reset, and similar situations are treated as the priority they are.
Call (227) 294-9289 and we will tell you what is available.
Outdoor wiring work, including exterior lighting, landscape circuits, and weatherproof outlet installation, is affected by rain and standing water. We confirm site conditions when the visit is booked and will reschedule if the conditions on the day are not safe for the work. Dry conditions and clear access to the work area are what the job requires.

What does it mean if my lights dim when a large appliance turns on?
A brief dip when a large motor starts, like a refrigerator compressor or an air handler, is normal. If the dimming is significant, lasts more than a moment, or happens on circuits that have nothing to do with the appliance, it usually points to a service capacity issue or a loose connection somewhere in the supply. A load calculation and a look at the panel will tell us whether the service size is the problem or whether something else is going on.
How do I know if my home is ready for the electrical load of a new appliance or workshop?
The short answer is a load calculation. We look at what the panel is currently carrying, what the new appliance or workshop will add, and whether the service size has room for both. If it does not, a panel or service upgrade is the next step. We scope that as part of the same call so you have the full picture before committing to anything.
What is involved in installing a backup generator hookup?
We install the transfer switch, run the generator wiring, and connect it to the existing panel. The transfer switch is what keeps the generator isolated from the utility line when it is running, which matters both for safety and for the utility's requirements. We do not sell or size the generator itself, but we can tell you on the call what the electrical side of the hookup involves for your panel and service.
Faults Traced Before Anything Is Replaced
We trace a fault from the symptom back to the source before recommending any repair. That means you are not paying to replace parts that were not the problem.
What does EV charger installation actually involve on the electrical side?
A Level 2 home charger needs a dedicated 240-volt circuit, typically on a 50-amp breaker. Before any wire is pulled, we do a load calculation to confirm the panel can carry the added circuit. If the panel is already near capacity, a service upgrade may be needed first. We scope both as part of the same call so you are not surprised by a second visit.
Why are aluminum branch wiring and knob-and-tube wiring a concern in older homes?
Knob-and-tube wiring was designed for much lighter electrical loads than a modern home puts on a circuit, and it lacks a ground conductor entirely. Aluminum branch wiring expands and contracts at connection points more than copper does, which loosens those connections over time and creates heat at the joint. Both are worth having assessed if your home was built before the mid-1970s. Whether full replacement or targeted remediation is the right answer depends on what an inspection finds.
How long does a panel upgrade or whole-home rewire typically take?
A panel upgrade is usually a single-day job. A whole-home rewire takes longer and depends on the size of the home, how much of the wiring needs to be replaced, and whether walls need to be opened. We give you a realistic time estimate on the call after we understand the scope, and we let you know what access and preparation the job will require.
Older and Newer Wiring Both Handled
Knob-and-tube, aluminum branch circuits, and modern copper wiring all come up regularly in Montgomery County homes. We assess what is there and explain what the options are before any work starts.
Is a permit required for panel upgrades and rewiring work?
Panel upgrades and full rewiring projects typically require a permit and a final inspection in Montgomery County. We handle that process as part of the job. The work is done to the standard the inspection will apply.
How do estimates and pricing work before any work starts?
When you call, we go through the scope on the phone and give you a price before anything is scheduled. You know what the job covers and what it costs before we come out. If the work turns up something unexpected once we are on site, we stop and explain what we found before any additional work proceeds. Nothing is added to the scope without your agreement.
Scope Agreed Before the Panel Is Opened
The price and the scope are confirmed on the call before we schedule. If something changes once we are on site, we stop and explain it before continuing.
When should I call an electrician instead of trying to fix something myself?
Anything involving the panel, the service entrance, or wiring inside a wall is work for an electrician. GFCI outlet replacement is a job many homeowners handle, but if the outlet keeps tripping, if the wiring behind it looks unusual, or if you are not certain what you are looking at, a call is the right move. A burning smell, a warm outlet, or a buzzing panel are situations where waiting is not a good idea regardless of how handy you are.
What does grounding and bonding mean, and why does it matter in an older home?
Grounding gives fault current a safe path back to the source so a breaker can trip and clear the fault. Bonding ties metal components together so they stay at the same electrical potential. Older homes were often wired without a ground conductor on branch circuits, and the bonding of metal plumbing and gas lines was not always completed to current standards. Both affect how safely the system responds to a fault, and both come up during a safety inspection.
What does it mean if an outlet is warm to the touch or makes a buzzing sound?
A warm outlet usually means a connection inside has loosened and is generating heat under load, or a device plugged into it is drawing more current than the outlet is rated for. A buzzing sound points to arcing at a loose connection. Both are warning signs that the outlet and the circuit feeding it need to be looked at. Taking the outlet out of service until it is diagnosed is the right call.
Call (227) 294-9289 and we will walk through your situation, give you a straight price, and get it on the schedule.
