Electrical Inspections & Code Corrections
in DC, Maryland & Northern Virginia
Maybe you’re under contract on a home in Alexandria and want to know what you’re getting into, electrically, before you close. Maybe your contractor mentioned that the kitchen addition you’re planning might trigger code compliance requirements beyond the kitchen itself. Or maybe your homeowner’s insurance carrier sent a letter asking about the age of your electrical panel.
In all three cases, what you need is the same: a licensed electrician who can look at your home’s electrical system honestly, tell you what’s there, and handle anything that needs to be updated.
John C. Flood’s electrical services team has been doing exactly that for more than 120 years across DC, Maryland, and Northern Virginia. We inspect home electrical systems, explain what we find in plain terms, and handle any code corrections with the same team. There’s no hand-off and no second contractor. Just a clear assessment, honest pricing, and work that gets done right.
Signs It May Be Time for an Electrical Inspection
Electrical systems don’t always send obvious signals when something needs attention. A few situations, though, make scheduling an inspection a practical next step.
Consider booking a home electrical inspection if any of the following apply to you:
- You’re buying or selling a home, particularly one that’s more than 20 years old
- Your home is 20 to 25 years old or older and has never had a dedicated electrical review
- You’re planning a renovation or addition, since pulling permits can trigger code compliance requirements that reach beyond the rooms being renovated
- Your homeowner’s insurance carrier has flagged electrical concerns or asked for a formal inspection
- You’ve noticed flickering lights, outlets that feel warm to the touch, or breakers that trip repeatedly
- You’ve detected a burning smell near an outlet, a panel, or a light fixture
- Your home had recent storm damage or water got near the electrical panel or wiring
- A previous owner completed electrical work and it’s unclear whether it was permitted or inspected
- You’re adding an EV charger or a high-demand appliance and want to confirm your system can support it
If you’re not sure whether your situation calls for a visit, give us a call. Our electricians will ask a few questions and help you figure out whether an inspection makes sense. You don’t need to diagnose anything before we come out.
What Our Electricians Find (and Fix) In DMV Home Inspections
The homes in DC, Maryland, and Northern Virginia span more than a century of construction. Pre-war row houses in Capitol Hill and Old Town Alexandria, mid-century ranches and split-levels across the Maryland and Northern Virginia suburbs, townhomes and single-family homes from the outer-suburb building booms of the 1980s and 1990s. Each era of construction came with its own electrical standards, and homes that were built to code when they were built may have systems that no longer meet current requirements.
When our electricians identify one of these conditions during an inspection, the same team handles the correction. Homeowners don’t need to find a separate contractor.
Outdated or Flagged Panels
Federal Pacific Stab-Lok and Zinsco panels are a common find in DMV homes built between the 1950s and the 1980s. Both brands have been widely documented for breakers that may not trip under certain fault conditions, which affects how the system responds when it needs to protect itself. Undersized 100-amp services, which were standard in homes built before the 1970s, are another common finding and may not be adequate for the electrical demands of a modern household. If your home has one of these panels or an older service, our electricians will explain what you have and what an electrical panel replacement or upgrade would involve.
Missing AFCI and GFCI Protection
Two types of protection are now required by modern electrical code that most older homes don’t have. Our electricians identify exactly where protection is missing and install what’s needed.
- Arc fault circuit interrupter (AFCI) breakers detect certain types of electrical arcing that can occur in damaged or aging wiring, and they are now required for bedroom and living area circuits in homes built or renovated to current code.
- Ground fault circuit interrupter (GFCI) outlets are required in areas where water and electricity are in proximity, including kitchens, bathrooms, garages, and outdoor locations. Older homes commonly lack GFCI protection in one or more of these locations.
Aluminum Wiring and Knob-and-Tube
Two older wiring types come up regularly in DMV homes, and both are worth knowing about. For both, our electricians assess what’s present and explain the options for rewiring or remediation in terms that are easy to act on.
- Aluminum branch wiring was used in homes built between roughly 1965 and 1973, particularly in Northern Virginia’s post-war subdivisions and Maryland’s older housing stock. It’s something our electricians see regularly and know how to work with, but aluminum wiring requires specific handling at connections, and some insurance carriers ask about it directly.
- Knob-and-tube wiring shows up in the region’s oldest properties: DC row houses, Alexandria’s historic districts, and older homes in Bethesda and Chevy Chase. It has no ground wire, and its age alone often raises questions for buyers and insurers alike.
Double-Tapped Breakers
A double-tapped breaker is one where two wires share a single breaker slot that was rated for only one conductor. It’s a common result of circuits being added to a panel over the years without a proper expansion of the panel itself, and it turns up frequently in homes that have changed hands a few times or had additions and basement finishes completed at different points. Our electricians identify double-taps during the panel inspection and address them through breaker reconfiguration or replacement.
Ungrounded Outlets
Two-prong outlets and three-prong outlets that lack a proper ground are common in homes that haven’t had their electrical systems updated since original construction. They also appear in rooms where a previous owner added outlets without running a ground conductor. Our electricians identify where outlet upgrades are needed and handle whatever the fix requires, whether that’s the outlets themselves or the conductors behind them.
Dedicated Circuit Gaps
Kitchens in older DMV homes often don’t have the dedicated 20-amp circuits that current code requires for small appliances, and homes without a dedicated circuit for a high-draw appliance or EV charger may run into a code requirement before those upgrades can move forward. Our electricians identify where dedicated circuits are needed and add them, including any panel capacity evaluation required to support the new load.
Unpermitted or Non-Code DIY Work
Finished basements, added outlets, and wiring run without permits are among the most common findings in homes that have had multiple owners over the years. These modifications get evaluated against current code during the inspection. Where corrections are needed, our electricians bring the existing work into compliance or replace it properly. All work that requires a permit gets permitted through the appropriate local jurisdiction.
Our Electrical Inspection & Code Correction Process
When you schedule with John C. Flood, here’s what happens from the first call to the final walkthrough.
- Schedule your assessment. An electrician comes to your home at a time that works for you.
- Thorough walkthrough. The electrician moves through the accessible parts of your home’s electrical system, checking the panel, wiring, outlets, grounding, and safety devices.
- Clear summary of findings. Before any conversation about next steps, the electrician walks you through what was found in plain language: what’s in good shape, what may benefit from an update, and what should be addressed.
- Honest recommendation. If code corrections are needed or recommended, the electrician explains what the work involves and why.
- Upfront pricing before work begins. We provide a flat-rate price before any correction work starts. There are no surprises after the fact.
- Licensed correction work, permitted where required. We handle permit applications for any correction work that requires them.
- Final walkthrough and testing. Before leaving, the electrician confirms that all completed work is functioning correctly and answers any remaining questions.
The goal of every appointment is to leave you with a clear picture of your home’s electrical system and confidence in whatever work was done. Schedule your electrical assessment when you’re ready.

There are a few reasons homeowners across DC, Maryland, and Northern Virginia have been calling John C. Flood for more than 120 years, and one of them matters especially on this page.
John C. Flood is a full-service home services company, not an electrical-only contractor. That matters during an inspection because electrical systems don’t always stay within their own category. Water intrusion near a panel often has a plumbing source. A circuit running to HVAC equipment may connect to work your heating or cooling system needs. When our electricians find something that touches another trade, you have one number to call and one team that can address it.
Beyond that, here’s what makes working with us straightforward:
- Our electricians are licensed, insured, and familiar with the electrical systems found in homes throughout DC, Maryland, and Northern Virginia
- The same team that conducts the inspection handles any code corrections, so there’s no gap between diagnosis and repair
- We provide honest, upfront pricing before any correction work begins
- We offer flat rates seven days a week, with coupons available on qualifying work
- Our call center is available 24/7 to take your call
- We’ve spent more than a century working in and giving back to the communities we serve across the DMV region
FAQs About Electrical Inspections & Code Corrections
Is a home electrical inspection the same as a general home inspection?
They are not the same service. A general home inspection covers the electrical system at a surface level, noting visible concerns but not going into depth. A dedicated electrical inspection by a licensed electrician goes further: the panel is opened and evaluated, outlets are tested for proper grounding and GFCI and AFCI function, visible wiring is examined, and code issues that a generalist inspector may not be trained to identify are flagged.
Is a dedicated electrical inspection recommended before buying or selling a home in DC, Maryland, or Virginia?
It’s a practical step, particularly for homes that are more than 20 to 25 years old. For buyers, an electrical inspection gives you a detailed picture of what you’re taking on, which can inform negotiations if updates are needed. Sellers who address concerns before listing tend to have smoother transactions. Either way, a clear picture of the system’s condition before the sale is useful for everyone involved.
What triggers electrical code correction requirements when I renovate?
Pulling renovation permits in most DC, Maryland, and Northern Virginia jurisdictions can require the electrical system to be brought into compliance with current code, sometimes beyond the rooms directly involved in the renovation. The scope depends on the jurisdiction, the type of project, and what the permit inspector finds. A pre-renovation electrical inspection is a practical way to understand what may be required before you pull permits, so there are no surprises mid-project. Our electricians can also evaluate whether your existing electrical panel has the capacity for any planned additions.
How do I know which code corrections are required versus just recommended?
Some corrections are required before a permit can close, an insurance policy renews, or a sale can proceed. Others are improvements worth considering but not immediately mandated. After the inspection, the electrician will clearly explain which findings fall into which category so you can make an informed decision about what to address and when.
