"John and his team replaced our entire electrical panel in one day. They were professional, clean, and explained everything clearly. Could not recommend them enough!"
— Sarah M., Cornwall
"We had an emergency at 10PM on a Saturday night — a burning smell from our outlet. John was at our house within 30 minutes. That kind of service is rare these days."
— Mike and Lisa T., New Windsor
"Simple ceiling fan install but John treated it like the most important job of the day. On time, clean work, reasonable price. Will call again for sure."
— Jenn L., Mountainville
"Had recessed lighting installed in our kitchen and living room. Great work at a fair price. The only reason for 4 stars instead of 5 is scheduling took a bit longer than expected."
— David R., Highland Falls
"John installed a Level 2 charger for our Tesla. He handled everything including the permit. Very smooth process from start to finish."
— Karen W., Newburgh
