DIY vs. Electrician for GFCI Work
Direct answer: A straightforward, like-for-like swap of an existing outlet for a GFCI version — same location, already grounded, single circuit — is within many confident homeowners' skill level with the breaker off and a voltage tester in hand. Anything involving an ungrounded circuit, a shared/multi-wire neutral, new wiring runs, or panel-level breaker work is a meaningfully higher risk category best left to a licensed electrician.
DIY parts for a single outlet run about $15-30, versus a typical licensed installed cost of $150-600 — but that gap reflects labor, code compliance, and liability, not just the part.
What tips the decision toward DIY
The existing wiring is already grounded and in good visible condition, it's a single dedicated circuit (not shared/multi-wire), the outlet count is small, and you're comfortable shutting off the breaker and verifying zero voltage with a tester before touching any wires.

What tips the decision toward hiring a pro
Aluminum wiring, any sign of an ungrounded or two-wire system, a shared neutral between two circuits, panel or breaker-level work, any location requiring a permit and inspection, or simply not having (or wanting to buy) a reliable voltage tester and the confidence to use it correctly.
