I had a gentleman named Imad come to my house. He called me just before arriving, and was on time which is always helpful. A very friendly guy, very respectful, and had a great sense of humor. I was home the whole time, so was watching him with everything he was doing. He was very thorough and very knowledgeable with his job, as he would show me something, and explain it to me as well. We had a great time chatting, and I would highly recommend Alpha, and Imad to anyone!
