Protect your family from electrical shock with code-required GFCI outlets.

Ground Fault Circuit Interrupter (GFCI) outlets are one of the most important safety devices in your home, designed to instantly cut power when they detect current leaking to ground -- the condition that causes electrical shock. The National Electrical Code requires GFCI protection in kitchens, bathrooms, garages, basements, laundry rooms, outdoor areas, and anywhere within six feet of a water source. Many older Northern Virginia homes built before the 1990s lack adequate GFCI coverage, leaving families vulnerable to potentially fatal shocks. AJ Long Electric installs and upgrades GFCI outlets throughout Fairfax County, Loudoun County, Arlington, and the greater DC metro area. Our licensed electricians assess your home's existing outlets, identify locations where GFCI protection is required or recommended, and install tamper-resistant GFCI receptacles that meet current NEC 2020 standards. We also test every installation to verify proper trip response times and grounding. Whether you need a single GFCI outlet added to a bathroom or a whole-home upgrade to bring your property up to code for a sale or renovation, we deliver fast, reliable service with clear pricing and no surprises.
GFCI outlets detect ground faults in as little as 1/40th of a second and cut power before a dangerous shock can occur.
Meet current NEC requirements for kitchens, bathrooms, garages, basements, and outdoor areas.
Tamper-resistant GFCI outlets prevent children from inserting objects into receptacle slots.
Updated GFCI protection satisfies home inspection requirements and can improve insurance standing.
GFCI outlets are one of the most cost-effective safety upgrades available for any home.
Our licensed electricians are ready to assist you in Northern Virginia.
Serving Fairfax, Arlington, Alexandria, Loudoun, and Prince William Counties.
Fairfax, Arlington, Alexandria, Loudoun & Prince William Counties
GFCI outlet installation is one of the most requested electrical services in Northern Virginia, driven by the region's active real estate market and the large number of homes built before GFCI requirements expanded to cover kitchens, garages, basements, and outdoor areas. Fairfax County alone processes tens of thousands of home sales annually, and missing GFCI protection is consistently the most common electrical deficiency flagged during buyer inspections. Homes built before 1987 typically lack kitchen GFCI protection, homes before 1990 often lack garage and basement coverage, and homes before 2005 may be missing GFCI protection in laundry areas and utility rooms. Northern Virginia's humid climate and frequent thunderstorms make ground fault protection especially important -- moisture intrusion into outdoor outlets, garage floor dampness, and basement humidity all increase the risk of ground fault events that GFCI outlets are designed to prevent. The region's many swimming pools, outdoor kitchens, and covered patios create additional GFCI requirements under NEC 680 for pool areas. Whether you are preparing a home for sale in Vienna, renovating a kitchen in Arlington, or adding an outdoor entertainment area in Ashburn, proper GFCI protection is both a code requirement and a critical safety investment for your Northern Virginia home.
See how we have helped homeowners across Northern Virginia with their gfci outlet installation needs.
Challenge
A Fairfax homeowner preparing to sell their 1985 colonial received a home inspection report flagging 14 locations where GFCI protection was required but missing. The kitchen had no GFCI outlets despite having countertop receptacles within reach of the sink, both bathrooms had standard outlets, and the garage and outdoor receptacles lacked ground fault protection entirely. The buyers were threatening to walk.
Solution
We installed tamper-resistant GFCI outlets at all 14 flagged locations including three kitchen countertop positions, four bathroom outlets, two garage receptacles, three outdoor outlets with in-use weatherproof covers, the laundry room outlet, and the unfinished basement receptacle. We configured downstream protection so that each GFCI device also protected additional standard outlets on the same circuit.
Result
All 14 code deficiencies were resolved in a single 4-hour visit. The buyers' re-inspection passed with no electrical flags, and the sale closed on schedule. Total cost was significantly less than the $5,000 buyer credit that had been negotiated.
Challenge
A homeowner in a Reston townhome was renovating their kitchen and discovered during demolition that none of the existing kitchen circuits had GFCI protection. The original 1990 construction used standard outlets for all countertop receptacles. Additionally, the existing wiring was two-wire without a ground conductor, complicating the GFCI installation.
Solution
We installed GFCI outlets at all six countertop positions and the dishwasher circuit using the NEC-approved method for ungrounded circuits. Each GFCI was properly labeled 'No Equipment Ground' as required by code. We also added a GFCI-protected outlet for the garbage disposal and configured the circuits so the refrigerator was on a dedicated non-GFCI circuit to prevent nuisance tripping from compressor cycling.
Result
The kitchen renovation passed electrical inspection on the first visit. The homeowner has full GFCI protection throughout the kitchen, and the proper labeling ensures future electricians understand the wiring configuration.
Challenge
A Woodbridge family built an extensive outdoor entertainment area with a covered patio, outdoor kitchen, landscape lighting, and a hot tub. The existing outdoor electrical consisted of two unprotected standard outlets on the back of the house. None of the new outdoor electrical work had GFCI protection, and the hot tub was wired to a standard 50-amp breaker without ground fault protection.
Solution
We installed in-use weatherproof GFCI outlets at four locations around the patio and outdoor kitchen, replaced the hot tub breaker with a GFCI breaker at the panel, and added a dedicated GFCI-protected circuit for the landscape lighting transformer. We also upgraded the two original back-of-house outlets to tamper-resistant GFCI devices with horizontal in-use covers rated for wet locations.
Result
The outdoor area now meets all NEC requirements for wet and damp location GFCI protection. The hot tub GFCI breaker provides the personnel protection required by NEC 680 for spa installations. The family can use their outdoor space safely in all weather conditions.
Challenge
A McLean estate owner converting a pool house into a guest suite discovered that the entire structure lacked GFCI protection. The pool house had a kitchenette, full bathroom, outdoor shower, and multiple outlets within 6 feet of the pool. An insurance inspection had flagged the pool area electrical as non-compliant, threatening coverage cancellation for the pool structure.
Solution
We installed 12 GFCI outlets and two GFCI breakers throughout the pool house. The kitchenette received three tamper-resistant GFCI outlets, the bathroom received two, the outdoor shower area received a weatherproof GFCI outlet, and all pool-adjacent outlets within 20 feet of the water were GFCI protected per NEC 680. We replaced the pool pump and heater breakers with GFCI breakers as required for pool equipment.
Result
The pool house passed both the county building inspection and the insurance company's re-inspection. The insurance carrier restored full coverage for the pool structure and guest suite, and the conversion was completed on schedule.
Permit requirements for gfci outlet installation vary by county. We handle the entire permitting process for you.
Permit Process
Replacing existing outlets with GFCI outlets does not require a permit in Fairfax County. Adding new circuits or outlets to locations without existing electrical requires a permit through Fairfax County Land Development Services. Like-for-like GFCI replacements and upgrades are considered maintenance.
Inspection Notes
Fairfax County home inspections consistently flag missing GFCI protection as the most common electrical deficiency. Addressing GFCI compliance before listing eliminates the number one electrical negotiation point.
Special Requirements
Permit Process
GFCI outlet replacement does not require a permit in Loudoun County. New circuit installations require permits through Loudoun County Building and Development. Loudoun County follows the Virginia Uniform Statewide Building Code which adopts the NEC with state amendments.
Inspection Notes
Newer Loudoun County homes built after 2002 should already have GFCI protection in most required locations, but kitchen countertop coverage and outdoor outlets are frequently found to be inadequate during resale inspections.
Special Requirements
Permit Process
Standard GFCI outlet replacement is not a permitted activity in Prince William County. Adding new outlets or circuits requires a permit through Prince William County Development Services. GFCI breaker installation at the panel for hardwired equipment like hot tubs may require a permit depending on scope.
Inspection Notes
Prince William County homes in the Woodbridge and Manassas areas frequently lack outdoor GFCI protection and hot tub GFCI compliance. Pool and spa installations are strictly inspected for NEC 680 compliance.
Special Requirements
Permit Process
Arlington County does not require permits for GFCI outlet replacements. New circuit work or adding outlets where none existed requires a permit through Arlington County Inspection Services. Arlington's older housing stock means many GFCI installations involve homes with ungrounded wiring requiring special installation methods.
Inspection Notes
Arlington County has the oldest average housing stock in Northern Virginia. GFCI installations on ungrounded circuits are very common and must be properly labeled per NEC requirements.

Get answers to common questions about our gfci outlet installation services.
A GFCI outlet continuously monitors the flow of electricity between the hot and neutral wires. If it detects even a tiny imbalance (as little as 4-5 milliamps), it trips in 1/40th of a second, cutting power before a dangerous shock can occur. This protects against electrocution in wet areas like kitchens and bathrooms.
The NEC requires GFCI protection in bathrooms, kitchens (countertop receptacles), garages, unfinished basements, crawl spaces, laundry areas, outdoor outlets, and anywhere within 6 feet of a sink or water source. Virginia follows the NEC, so all these locations require GFCI outlets in new installations or renovations.
A single GFCI outlet installation typically costs $150-$300 in the DC metro area, depending on whether existing wiring supports the upgrade or new wiring is needed. Replacing multiple outlets at once reduces the per-outlet cost. We provide upfront pricing during our assessment.
While it is physically possible, we strongly recommend professional installation. Incorrect GFCI wiring can create a false sense of security where the outlet appears to work but does not actually provide ground fault protection. Our electricians verify proper operation with professional testing equipment.
Frequent GFCI trips can indicate a genuine ground fault in an appliance, moisture in the outlet box, deteriorating wiring insulation, or a faulty GFCI device. If your GFCI trips repeatedly, do not simply reset it and ignore the problem -- call a licensed electrician to diagnose the cause, as it may be preventing a serious shock hazard.
The NEC recommends testing GFCI outlets monthly by pressing the test button, verifying power cuts off, then pressing reset. GFCI outlets have a lifespan of about 10-15 years and should be replaced if they no longer trip when tested. Our electricians can test all your GFCIs during a routine inspection.
A GFCI outlet protects only the outlets downstream from it on the same circuit. A GFCI breaker, installed in your electrical panel, protects the entire circuit. GFCI breakers are useful when you need protection for multiple outlets or hardwired equipment. We help determine which approach is best for your situation.
Yes, GFCI outlets can be installed on ungrounded (two-wire) circuits and will still provide ground fault protection. However, they must be labeled 'No Equipment Ground' per NEC requirements. This is a common solution for older Northern Virginia homes with original two-wire wiring that has not been updated.

AJ Long Electric has installed thousands of GFCI outlets across Northern Virginia, from single bathroom upgrades to comprehensive whole-home GFCI compliance packages for real estate transactions. Our electricians understand the specific challenges of GFCI installation in the DC metro area's diverse housing stock -- from 1940s Arlington homes with ungrounded wiring that requires special GFCI techniques and proper labeling, to modern Loudoun County homes where builder-installed GFCI outlets have failed and need professional replacement. We do not simply swap outlets and leave. Every GFCI installation includes testing with calibrated equipment to verify the device trips within the NEC-required response time and current threshold. We configure downstream protection to maximize coverage, ensuring that each GFCI device protects not just its own location but also any standard outlets further down the circuit. For outdoor installations, we use only in-use rated weatherproof covers that meet NEC requirements for wet locations, not the cheap flip covers that leave outlets exposed when cords are plugged in. Our transparent pricing, typically $150-$300 per outlet or $800-$1,500 for a whole-home package, means no surprises on your invoice. We are the GFCI specialists that Northern Virginia real estate agents and home inspectors recommend to their clients.
