Code Compliance / GFCI Services in San Antonio

At Mister Sparky^® we strictly adhere to, and comply with, the local and national electrical codes as dictated by the National Electrical Code (NEC), which is published by the U.S. National Fire Protection Association (NFPA 70). The NEC is a United States standard for the safe installation of electrical wiring and equipment. While the NEC is not itself a U.S. law, the use of NEC is commonly mandated by state or local law, as well as in many jurisdictions outside of the United States. The NEC codifies the requirements for safe electrical installations into a single, standardized source.

Some electric code violation guidelines of interest include:

Bathrooms

You can only install GFCI (ground fault current interrupter) receptacles in bathrooms.
There must be a receptacle within 3 feet of the outside edge of sink basin.
No receptacles face-up on countertops.
Because some receptacles power high-wattage devices like hair dryers, there must be at least one separate 20 amp. branch circuit.

General Rooms

There should be wall receptacles every 12 feet.
Receptacles should be on any wall space that is more than 24 inches wide.
Hallways more than 10 feet in length must have at least one receptacle.

Kitchens

All countertops receptacles must be GFCI.
There can be no receptacles more than 20 inches above countertops. (Exceptions are for the physically handicapped and for islands or peninsulas where this is not possible).
There should be receptacles above all countertops that are 12 inches or wider.
No face-up receptacles.
At least one receptacle should be located on islands or peninsulas.

Thank you Luciano for scheduling my mounting quote appointment promptly and efficiently. Kevin showed up and did an amazing job with the inspection he provided for our new home. Kevin was very knowledgeable and really seemed passionate about his work. I appreciate the great service!

Ant and Mark did an excellent job servicing my home today. They came out to give an estimate on my issue with no power to my water heater. They found that the water heater breaker was tripping and not resetting. I provided the breaker and they replaced that for me but they noticed in the laundry room was missing a bushing and the grounding wasn’t up to par along with a loose box. They did a great job of letting me know the issues and provided options for me. I will be recommending to family and friends the great work they completed for me. I now have hot water ; and now a happy customer!

Buck was extremely helpful. Replaced a GFCI and diagnosed a larger problem in our house. Explained everything really thoroughly and was really friendly. Enjoyed talking to him and having him in the house. Would absolutely come back to Misty Sparky again based on this experience.

- Chris Schalk

Frank arrived, assessed the situation, and gave me options for what I want completed. He explained all options and once I made the decision, he went to work like a Boss! He was pleasant to talk with and answered all questions completely. What I liked most, he enjoyed doing what he knows how to do. He deserves a bonus! Thank you Frank and staff for getting here as quick as you did to complete an urgent matter. You’re tops in my book. Mr. Sparky will be my first and only call when service is required. OUTSTANDING!

New update 11/7/25- I had Mister Sparky out again for new electrical tasks since my first review. Again very pleased and will continue to call them for my needs. This time I had Matthew and team and it was a big job and they were extremely professional and respectful (and did a great job) Original review: Very pleased- Art was my electrician and he was so kind and professional. He did a great job hanging a very big light fixture on a very tall ceiling.
