What it costs and what's actually happening
Here's the short version: an outdoor GFCI that suddenly won't reset costs $140–$400 to fix with a licensed electrician in 2026.
The reason for the spread is diagnosis. A dead GFCI is a $30 part. Water buried in a cable run is a half-day of tracing.
A GFCI that refuses to reset is not broken. It caught a ground fault and shut the circuit down on purpose. Your job (or your electrician's) is to find where the current is leaking, not to force the button.
Outdoor outlets fail this way constantly because they live in the worst conditions in your house: rain, sun, bugs, and lawn tools swinging nearby.
Where the money goes in 2026
Parts on this job are cheap. Labor and diagnosis are where the bill forms.
A quality outdoor-rated GFCI outlet runs $18 to $45. A weatherproof in-use cover (the bubble kind that closes over a plugged-in cord) is $12 to $30. Both are worth buying new if yours are old or cracked.
Most of that is the tester and tools you'll keep.
With a pro, the $140–$400 range breaks down as a service call and first hour ($150 to $250 in most metros), the GFCI and cover, and the labor to diagnose and confirm the fix.
The number climbs past $400 when the fault is in buried cable or a hidden junction box. Tracing and repairing outdoor wiring can add $200 to $600 depending on how far they have to dig or fish.
Trenching to replace a damaged underground run is its own project and can run $800 to $2,000-plus. It's uncommon, but it's why nobody can quote this blind over the phone.
How we built these numbers
The cost ranges reflect 2026 US pricing for residential electrical work, blending typical service-call minimums, common metro labor rates, and current retail prices for outdoor-rated GFCI outlets and in-use covers.
DIY figures assume you buy a quality outlet and cover plus a basic voltage tester, and that the fix really is a device swap or a dry-out.
Pro figures assume a licensed electrician diagnosing and repairing a standard outdoor GFCI fault, not major cable replacement or trenching, which we call out separately as higher-cost scenarios.
Actual prices swing with your region, how buried or hidden the fault is, and how long the outdoor run is. Get a firm quote after diagnosis, not before.
