"Paul is extremely professional and knowledgeable. Kept me informed from the first phone call to the day he and his team showed up. Very honest and provided quality work. He corrected a switch that was not up to code, installed high hats, an outdoor outlet, and fixed an issue with lost power to a flood light. He and his crew did a great job and worth every penny!"

"Fast and super helpful. Gave me a proposal right away. Started work same week. If deviations were needed, was specific on what and why. Reasonable and fair pricing, and honest about their capabilities and areas of expertise. Professional team and went out the way to provide additional references for other concerns. I also appreciated the video Fabio took to show me the before and after, especially in areas I was unable to see."
