"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!"

"This was a great company to work with and I have already hired them to do additional work on my house. Their guys arrived on time, with masks, and completed all the work efficiently and in line with the estimate I was given. They even sent out a team to troubleshoot my house after another contractor tripped some outlets. The guys were super patient with me and didn’t seem to mind my asking a ton of questions. Can’t say enough good things about Matt Blattner and his company. They will be my electricians for as long as I live in this house."
