Electrical Repairs
Troubleshooting outlets, breakers, flickering lights, GFCIs and other common residential electrical problems.
Why does my circuit breaker keep tripping?+
A breaker that repeatedly trips may indicate an overloaded circuit, short circuit, ground fault, faulty appliance, or wiring problem. If the breaker continues to trip during normal use, an electrician should inspect the circuit instead of repeatedly resetting it.
Why are some electrical outlets in my house not working?+
Several issues can cause dead outlets, including a tripped GFCI, failed breaker, loose connection, damaged receptacle, or wiring problem. If resetting nearby GFCI outlets and the electrical panel does not restore power, the circuit should be professionally tested.
Why are my lights flickering?+
Flickering lights can be caused by a loose bulb or fixture, but persistent flickering may also point to loose electrical connections, overloaded circuits, voltage problems, or issues within the electrical panel. Widespread or recurring flickering should be inspected.
What does a buzzing electrical outlet or switch mean?+
Buzzing can indicate a loose connection, damaged switch, failing receptacle, electrical arcing, or another wiring problem. Electrical components normally should not buzz, so the device should be inspected rather than ignored.
What should I do if I smell burning near an outlet?+
A burning smell near an outlet, switch, panel, or electrical device can indicate overheating or damaged wiring. Stop using the affected equipment and contact an electrician promptly. Do not continue resetting breakers or using an outlet that appears overheated or damaged.
Why does my GFCI outlet keep tripping?+
A GFCI may trip because of moisture, a faulty appliance, damaged wiring, leakage current, or a failing receptacle. If it will not reset or repeatedly trips without an obvious cause, an electrician can test the circuit and connected equipment.
Panels & Breakers
Electrical panel capacity, breaker problems, service upgrades and modern household electrical demand.
When should I upgrade my electrical panel?+
An electrical panel should be evaluated when breakers trip frequently, the home needs additional circuits, major appliances or EV chargers are being installed, renovation work increases electrical demand, or existing equipment is outdated or damaged. Age is also a factor on its own: many Northern Virginia homes built before the 1990s were originally fitted with 60-amp or 100-amp panels, and fuse boxes instead of circuit breakers show up often enough in older homes that they're usually flagged during a home inspection or insurance renewal. A panel rated below 100 amps, visible rust or scorch marks inside the panel, or breakers that feel warm to the touch are all reasons to have a panel inspected sooner rather than later, even without an active problem.
What is the difference between a 100-amp and 200-amp electrical panel?+
The amp rating represents the amount of electrical service available to the home. A 200-amp service generally provides more capacity for modern appliances, HVAC equipment, EV charging, additions, and other electrical loads than a 100-amp service.
Do I need a 200-amp panel for an EV charger?+
Not every EV charger installation requires a 200-amp electrical service. The correct answer depends on your existing service size, household electrical demand, charger requirements, and available panel capacity. A typical Level 2 home charger draws 30-50 amps on a dedicated 240V circuit, so a 100-amp panel with an electric range, electric dryer, and central air can already be close to its limit, while a 150-amp or 200-amp panel usually has room to spare. Where capacity is tight, a load management device can often let the charger share the panel safely with existing appliances instead of requiring a full upgrade. A load evaluation should be completed before deciding whether an upgrade is needed, rather than assuming one way or the other.
Can more circuits be added to my existing electrical panel?+
Additional circuits may be possible if the existing panel has sufficient electrical capacity and physical breaker space. An electrician can evaluate the panel, service size, existing load, and proposed new circuits before making a recommendation.
How long does an electrical panel upgrade take?+
The timeline varies based on the existing electrical system, service equipment, utility coordination, permitting requirements, and the scope of work. A straightforward residential panel replacement may often be completed within a working day, while more involved service upgrades can take longer.
EV Chargers
Home Level 2 charging, dedicated circuits, panel capacity and residential EV charger installation.
Can you install a Level 2 EV charger at my McLean home?+
Yes. We provide residential Level 2 EV charger installation throughout McLean and Northern Virginia. Installation typically includes evaluating panel capacity, determining circuit requirements, running appropriate wiring, and connecting the charging equipment.
Does a Level 2 EV charger need a dedicated circuit?+
Most residential Level 2 EV charging equipment requires a dedicated electrical circuit sized for the charger and installation requirements. The circuit, breaker, conductor size, and charging equipment should be selected as part of the overall electrical installation.
Can an EV charger be installed outdoors?+
Many EV charging units are designed for outdoor installation when installed according to the manufacturer's requirements and applicable electrical standards. The location, equipment rating, wiring method, and weather exposure should all be considered.
Can you install a Tesla Wall Connector?+
Residential electricians can install compatible wall-mounted EV charging equipment, including Tesla Wall Connector systems, when the home's electrical capacity and installation location support the required circuit.
How long does home EV charger installation take?+
Installation time depends on charger location, distance from the electrical panel, panel capacity, wiring route, and whether electrical upgrades are necessary. A simple installation near an adequate panel can be considerably faster than one requiring a new circuit route or panel upgrade.
Lighting
Recessed lighting, exterior lighting, dimmers, LED troubleshooting and smart lighting controls.
Do you install recessed lighting in McLean homes?+
Yes. We provide recessed lighting installation, fixture replacement, switching, dimmers, and related electrical work for homes in McLean and surrounding Northern Virginia communities.
Can recessed lighting be added to an existing ceiling?+
In many homes, recessed lighting can be added to an existing ceiling using remodeling-style fixtures and carefully planned wiring routes. Access, joist locations, insulation, existing wiring, and ceiling construction determine the best installation approach.
Can you install exterior and landscape lighting?+
Yes. Exterior electrical work can include entry lighting, security lighting, architectural fixtures, landscape lighting, controls, timers, and other outdoor lighting improvements.
Why do LED lights flicker?+
LED lights may flicker because of incompatible dimmers, loose connections, failing drivers, voltage fluctuations, or problems elsewhere in the circuit. The fixture, controls, and electrical supply should be evaluated if the issue continues.
Can you install smart switches and dimmers?+
Yes. Smart switches, dimmers, connected lighting controls, and compatible automation devices can be installed when the existing wiring and electrical box configuration support the equipment.
Wiring & Older Homes
Rewiring, older electrical systems, surge protection and electrical improvements for existing homes.
How do I know if my home needs rewiring?+
Possible signs include aging or damaged wiring, recurring electrical problems, insufficient circuits, ungrounded receptacles, overheating devices, renovation needs, or an electrical system that cannot safely support modern household demand. Two specific wiring types are worth knowing about if your home predates the 1980s: knob-and-tube wiring, identifiable by ceramic knobs and tubes in unfinished attics or basements, was common before the 1950s, and aluminum branch wiring was common in the late 1960s and early 1970s. Both are frequently flagged by home inspectors and insurers, and both are a stronger reason to have a professional look than simple wear alone. An electrical inspection can determine whether targeted repairs or broader rewiring is appropriate.
Can only part of a house be rewired?+
Yes. Some homes benefit from targeted circuit replacement or rewiring rather than replacing every electrical circuit. The appropriate scope depends on the condition of the existing wiring, renovation plans, electrical load, and safety concerns.
Can older wiring support modern appliances?+
That depends on the wiring type, circuit capacity, electrical panel, grounding, and condition of the existing system. Modern kitchens, HVAC equipment, EV chargers, and other higher-demand devices can require electrical upgrades in homes with older systems.
Do you install whole-home surge protection?+
Yes. Whole-home surge protection can be installed at the electrical service or panel to provide an additional layer of protection for appliances, electronics, HVAC equipment, and other electrical devices.
