"Great experience from start to finish! I would be happy to recommend his services to family and friends. Throughout the process he was punctual and communicative, I was always well informed what was happening. During installation of the panel he discovered a bad meter box that needed to be replaced, it was unavoidable. He was able to complete both repairs in a timely manor. Due to what work was performed a state inspection was required. it passed with no issues. For me, the whole experiences was great, I never felt pressured into any repairs that were out of the scope of what I was asking for. 5 stars from this guy!"

"The electricians and plumbers were very professional in their demeanor. They worked as a team, everyone knew what to do and how to do it. They answered all my questions, but didn't let that distract them from their job. I was impressed with the speed of the installation. They cleaned up after themselves and took their trash with them."
