GFCI Outlet Installation Cost: 2026 Prices and Code Rules
You plug a hair dryer into the bathroom outlet and it dies with a small pop. You press the reset button on the outlet. Nothing happens. A few minutes later, the kitchen outlet downstairs also stops working, and you start wondering how the two are connected.
That mystery usually points to a GFCI, a small safety device that cuts power when electricity takes the wrong path. It protects you from shock, but it also confuses people when it trips. Many homeowners learn about their GFCI only when it fails.
This guide breaks down the GFCI outlet installation cost across every common situation. You will see prices for the outlet itself, for an electrician’s labor, and for GFCI breakers. You will also learn where the code requires protection and how to test the device. Finally, you will see what to do when it will not reset.
Each price comes from published 2025 and 2026 cost guides, and we flag the one undated source. Your local quote will differ. Use these ranges to judge whether a bid is fair before you agree to the work.
Quick Answer: The GFCI outlet installation cost typically runs $120 to $350 per outlet, including the part and labor. The GFCI outlet itself costs $12 to $40. GFCI breakers cost $35 to $250 for the part alone. Required locations include kitchens, bathrooms, garages, basements, laundry areas, and outdoors.
How Much Is the GFCI Outlet Installation Cost?
Most electricians charge $120 to $350 to install one GFCI outlet. This Old House (June 2026) lists $120 to $200. HomeServe (June 2025) lists $150 to $350 per outlet, parts and labor included. Thumbtack lists $100 to $200 but does not show a page date.
The part is the smallest piece. HomeServe lists $12 to $40 for the outlet. The rest of the price covers the electrician’s time, the service call, and a test of the finished work.
Angi, HomeAdvisor, and Fixr do not publish a GFCI-specific price. That is why this guide leans on three sources and flags the gaps. Use the range as a starting point and confirm it with a local quote.
GFCI Outlet Installation Cost by Situation
Where the GFCI goes changes the price. A swap on an existing circuit costs less than new work in a finished wall. The table lists the figures we found.
| Situation | Typical Cost | Source |
|---|---|---|
| Replace an outlet with a GFCI | $120 to $200 | This Old House |
| Replace an outlet with a GFCI, parts included | $150 to $350 | HomeServe |
| Replace an outlet with a GFCI | $100 to $200 | Thumbtack |
| GFCI outlet part only | $12 to $40 | HomeServe |
| Standard outlet replacement for comparison | $80 to $200 | HomeServe |
| Outdoor outlet | $150 to $260 | Angi |
| Waterproof outlet | $200 to $400 | Fixr |
GFCI breakers follow a different pattern. This Old House lists $35 to $60 for the part. HomeServe lists $60 to $250 depending on the amp rating. No guide we reviewed publishes an installed GFCI breaker price, so ask for a written quote.

GFCI Outlet, GFCI Breaker, or Portable GFCI?
Three kinds of GFCI protection exist. Each fits a different need. The table compares them.
| Type | What It Protects | Best Use |
|---|---|---|
| GFCI outlet | Itself, and outlets wired after it | Single locations such as a bathroom or garage |
| GFCI breaker | Every outlet on one circuit | Circuits with many outlets or hard-to-reach wiring |
| Portable GFCI | Only what plugs into it | Temporary outdoor or workshop use |
The CPSC says a GFCI can be installed in the electrical system or built into a power cord. That is the portable option.
HomeServe lists GFCI breakers and downstream protection as alternatives to replacing each outlet. A single GFCI can sometimes protect several outlets wired after it. Ask your electrician whether that setup fits your circuit.
If you need breaker work, see circuit breaker replacement cost .
What a GFCI Does and Why It Matters
A GFCI monitors the current going out and coming back. If the two differ by a tiny amount, it cuts power. The CPSC says this can happen at as little as 0.006 amps, faster than a blink.
That speed matters. The agency says GFCIs protect people from severe or fatal shocks. They can also help prevent some electrical fires. The fact sheet adds that GFCIs have played a key role in reducing electrocutions.
The U.S. Fire Administration counted 23,700 residential building fires from electrical malfunctions in 2023. A GFCI does not stop every fire. It does reduce one major shock risk, which is why the code requires it in wet areas.
Where GFCI Outlets Are Required
Code requirements focus on places where water and electricity meet. IAEI Magazine summarizes the 2020 National Electrical Code for dwellings. It requires GFCI protection in these locations:
- Bathrooms
- Garages and accessory buildings
- Outdoors
- Crawl spaces
- Basements, finished and unfinished
- Kitchens
- Areas near sinks
- Laundry areas
- Indoor damp and wet locations
HomeServe lists a similar set, including any outlet within six feet of a water source. Earlier code editions covered fewer places. The 2017 edition applied to unfinished basements only and had no indoor damp location rule.
Code editions differ by state and city. Ask your electrician which edition your area uses. Our electrical inspection cost guide explains how an inspector checks for missing protection.
Whole-Home GFCI Upgrade: A Cost Example
Many older homes lack GFCI protection in several rooms. Upgrading them all adds up. Here is the math for an eight-outlet home. It has two kitchen outlets, two bathroom outlets, and one each in the garage, outdoors, basement, and laundry area.
| Price Source | Per Outlet | Eight Outlets Before Discounts |
|---|---|---|
| This Old House | $120 to $200 | $960 to $1,600 |
| HomeServe | $150 to $350 | $1,200 to $2,800 |
This is an illustration and not a quote. HomeServe says many professionals offer volume discounts and package pricing for larger jobs. A bundled bid should come in below these totals.
You may also cut the count. One GFCI can protect outlets wired after it. In that case, an electrician might install fewer devices than outlets. Ask for both a per-device price and a per-outlet price so you can compare.
Why GFCI Prices Vary From House to House
Two neighbors can pay very different amounts for the same device. Several factors explain the gap. Ask your electrician which ones apply to your home.
- Location: outdoor and wet areas may need weather-resistant covers and parts.
- Wiring condition: old or damaged wire adds time and repair costs.
- Ground wire: older homes may lack one, which changes the options.
- Device count: more devices raise the total, while bundling lowers the per-device price.
- Access: finished walls cost more than open or exposed wiring.
- Service call: some companies fold it into the quote, and others bill it separately.
A clear quote lists each of these items. That detail helps you compare bids fairly and keeps the GFCI outlet installation cost from drifting once work starts.
What an Installation Visit Looks Like
The visit follows a predictable sequence. The electrician turns off the breaker and tests that the circuit is dead. Then the pro removes the old outlet and checks the wires for damage. The GFCI connects to the line and load terminals as the manufacturer directs.
After installation, the electrician presses the test and reset buttons and confirms that power returns. A good pro also checks any outlets that sit downstream. Ask them to show you the test so you know how to repeat it each month.
GFCI Protection in Older Homes
Older houses often predate modern GFCI rules. You may find two-prong outlets with no ground wire, or a bathroom with no protection at all. A GFCI can improve safety in these homes, but the right setup depends on the wiring.
Ask your electrician about your options before you buy parts. Fixr lists an upgrade from two-prong to three-prong at $120 to $500. That work may add to a GFCI job. Aluminum and cloth-covered wiring need special care.
If your home has very old wiring, a larger project may make sense. See knob and tube wiring replacement cost for that case.
Is a GFCI Worth the Cost?
A GFCI costs less than most home repairs. At $120 to $350, it is a modest price for protection against shock. The CPSC credits GFCIs with a major part in reducing electrocutions. It also says thousands of electrical burn and shock injuries still occur in and around homes each year.
Compare that with the alternative. A bathroom or garage outlet without protection leaves you exposed when a cord is damaged or water is present. The GFCI outlet installation cost is small next to that risk.
The best time to upgrade is when an electrician is already on site. Bundling avoids a second service call and gives you a single bundled quote.
Outdoor and Garage GFCI Outlets
Outdoor outlets face weather, and garages face dampness and heavy tools. Both locations are on the code list above. Angi lists outdoor outlets at $150 to $260, and Fixr lists waterproof outlets at $200 to $400.
Use weather-resistant parts outdoors and keep covers in good condition. Test outdoor GFCIs monthly, since moisture is the most common stress on them. If a garage outlet trips often, check tools and extension cords before you replace the device.
Testing and Maintenance
A GFCI only helps if it works. The CPSC says to test every GFCI after installation, at least once a month, and after a power failure. It also says to follow the manufacturer’s instructions.
The agency offers a simple lamp test. Plug a lamp into the outlet and turn it on. Press the test button, and the light should go out. Press reset, and the light should come back on.
Read the results carefully. If the light does not go out, the GFCI is not working or was installed wrong. Call a qualified electrician. If the light does not return after you press reset, replace the GFCI.
Monthly testing costs nothing. It can reveal a failed device before you need it, and it keeps the protection you paid for reliable.
Why a GFCI Trips or Will Not Reset
A GFCI that trips is doing its job. The cause may be moisture, a damaged cord, or a faulty appliance. Sometimes the device itself has worn out.
Work through these checks:
- Unplug everything on the outlet and press reset.
- Plug devices back in one at a time.
- Look for moisture around outdoor and bathroom outlets.
- Check whether another GFCI upstream has tripped.
- Replace the GFCI if it will not reset with nothing connected.
A GFCI that trips only with one appliance points to that appliance. A GFCI that trips constantly points to the wiring or the device. If you cannot find the cause, call an electrician.
Damp basements and sump pump circuits trip GFCIs more often. See sump pump repair cost if your pump seems to be the trigger. For kitchen sink areas, see sink repair cost to rule out leaks.
Labor, Service Calls, and Permits
Labor shapes the total GFCI outlet installation cost. HomeServe lists electrician rates of $40 to $100 per hour and an initial visit fee of $75 to $125. Angi lists $50 to $130 per hour and a service call fee of $100 to $200. Our electrician cost per hour guide explains the differences.
A single swap takes little time, but many companies bill a one-hour minimum. That is why one GFCI can cost the same as a standard outlet swap plus a small premium.
Permits are usually not required for a like-for-like swap. New circuits and panel changes more often require one. Check with your local building department or ask your electrician.
Can You Install a GFCI Yourself?
Some homeowners do, which cuts the GFCI outlet installation cost to the price of the part. That part costs $12 to $40, so the savings are real. The risk is also real. A GFCI has separate terminals for incoming power and for protected outlets. Mixing them up can leave the device unprotected or nonfunctional.
If you try it, follow these safety steps:
- Turn off the breaker and confirm with a tester that power is off.
- Photograph the wires before you disconnect them.
- Read the manufacturer’s wiring instructions for the line and load terminals.
- Test the device with its test button after installation.
- Repeat the lamp test described above.
Skip the project if you see aluminum wire, scorched wire, or a breaker that keeps tripping. Our aluminum wiring repair cost guide covers one of those cases. When in doubt, hire a licensed electrician.
GFCI Outlet Installation Near Me: Hiring a Pro
Start with your state’s contractor license lookup. Then request written quotes from three electricians. Ask each one for a per-device price, the service call fee, and whether the quote includes testing.
Ask whether the electrician will check the circuit for other problems. A GFCI that trips often may be the first sign of a wiring issue. If many outlets need work, a whole-house project may make more sense. See whole house rewiring cost .
After-hours calls cost more. Angi says emergency work can run about double the standard rate. Our emergency electrician cost guide explains when a premium call is worth it.
Mistakes That Raise the Cost
Small errors can cost real money. Avoid these:
- Skipping the monthly test and discovering a failed device late.
- Reversing the line and load wires during a do-it-yourself install.
- Using a standard outlet outdoors instead of a protected, weather-resistant one.
- Booking several visits instead of bundling GFCIs into one trip.
- Replacing a tripping GFCI without finding the cause.
Each mistake has a simple fix. Test on a schedule, follow the wiring diagram, and bundle the work.
Related Upgrades Worth Planning Together
If an electrician is on site for other work, consider related upgrades. A whole-house surge protector guards every circuit. See whole house surge protector cost .
Garage GFCI protection also ties into vehicle charging. If you plan an EV charger, see EV charger installation cost . The same visit can cover the garage outlets.

Frequently Asked Questions
A Note on How to Read These Numbers
GFCI pricing is thinner than most electrical topics. Angi, HomeAdvisor, and Fixr list no GFCI-specific price. This guide leans on This Old House, HomeServe, and an undated Thumbtack page. HomeServe’s page also includes combined panel and GFCI totals. We left those out because they mix very different jobs.
The location list comes from a summary of the 2020 National Electrical Code. Your state may use a different edition, and we did not verify later changes. The CPSC fact sheet is dated 2010. Treat it as general guidance on how a GFCI works and how to test one. This site does not refer contractors. Use these ranges as a fairness check and get a local written quote.
Final Thoughts
For most homes, the GFCI outlet installation cost lands between $120 and $350 per outlet. The part itself costs only $12 to $40. Labor and the service call fee drive the rest. GFCI breakers and downstream protection can lower the count and the cost in some homes.
The key takeaway is to treat a GFCI as a safety device that needs a monthly check. A device that has never tripped may still be dead. The CPSC lamp test takes a minute and costs nothing. Fix any failed device promptly, because a dead GFCI offers no protection at all.
Your next step is to walk through the kitchen, bathrooms, garage, basement, laundry area, and outdoor outlets. Press the test and reset buttons on each GFCI you find. Write down any location that lacks one or fails the test, and request a single bundled quote.
