"I had an excellent experience with Austin — he called me within 10 minutes of submitting my request on Angi’s List. He arrived at my home within half an hour and got straight to work converting an old cable outlet into a new electrical outlet in my living room. The job was done quickly, cleanly, and exactly as requested. I also asked him to rewire my current outlet so it wouldn’t be controlled by a wall switch, and he handled that with no problem. He was prompt, professional, friendly, and genuinely happy to help — highly recommend!"

"My husband with Alzheimer’s can usually change a light switch but while doing the one in the bathroom couldn’t get it. I put an urgent message on Angie’s list and Terry from Zap electric gave me a call in a few minutes. He came and fixed the switch in 20 minutes. He was knowledgeable and so nice. He gave us a senior discount. A bathroom light is a must and he saved me that day. Please call him of you need any electrical!"

"Kelly Smith was very professional and he has great experience and expertise in electrical work. He was masked, gave me the quote for chandelier installment right away, and performed the work efficiently. I was slightly surprised by the price but that may just be the new norm. Thanks Kelly!"
