"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!"
