The answer to 'how much to replace GFCI outlet in my area' is that the cost can vary widely depending on several factors. Generally, you can expect to pay between $75 to $250 to have a GFCI outlet replaced by a licensed electrician in your local area.
The exact price will depend on the complexity of the job, the cost of materials, the electrician's labor rates, and your geographic location.
