People just like you say nice things about our service

  • We did a major remodeling of our master bedroom and bathroom and hired Superior Electrical to do all of the electrical work. They did a great job and proved themselves capable, competent, and reliable. Rich, Alex, and David will be our go-to electricians next time we need any electrical work.

  • Superior Electrical is a family owned and operated business that really does a thorough job and makes sure your problem is REALLY solved. Our garage electrical had stopped working due to some faulty wiring in the past. They came out last month and checked out the entire system and found a faulty installation of fuses, but still charged me as if it was just a small repair. Plus he taught us about what to do if the fuse--which is part of the hardwiring now--causes problems again so we can fix it ourselves. I like that.....

  • Superior Electrical came to our house when I had an outlet that was not working properly and while they where here; discovered some improperly wired items that could have caused a fire later in time. Later they told me about the ALL HOUSE Surge Protector and I was thrilled that they were able to install one for my home. So now all of my major appliances, PCs and TVs are safe. I highly recommend Supreior Electrical to all my friends and family. They are THE MOST reliable company I have ever used for electrical repair services.
