"I would highly recommend Naymar Electric to anyone looking for an excellent electrician. Their prices were very fair and competitive, their estimated timeframes given were more than reasonable and turned out to be accurate. I appreciated that David was readily available to answer my basic questions, as well as use his experience and creativity to wire the house in a way that would provide for future inhabitants and household configurations. He was very knowledgeable and informative, as well as creative and aesthetic, and he and his crew were hard workers that paid attention to detail and left the house easy to patch when they were through. I am so glad I went with Naymar Electric, they are now my go-to!!"
