Bill and his team did an exceptional job rewiring our basement. He updated all the electrical wirings that used to be knob and tube. He also added pot lights and new outlets where we needed them. Everything was preformed beyond our expectations and we were very happy with the overall quality and service. It is hard to find honest, experienced, knowledgeable, efficient and hardworking people who will show up early for jobs and are able to deliver as promised...Bill is definitely all that. We highly recommend Mark Electric for any of your electrical needs.
