Dependable and easy to work with. Carl and they added recessed lighting through the entire main floor and patched everything beautifully, and they picked up after themselves every single day. Would call them again without hesitation.

Quality work, fair price. Carl and they installed our EV charger and got the permit pulled same week.

Truly above and beyond. Carl and they diagnosed a panel issue two other companies completely missed, and they left the worksite cleaner than they found it. Saved their number to favorites.

These folks are the real deal. Carl wired up a whole-home generator and walked us through the transfer switch, and the whole crew showed up exactly when they said they would. They also sent us photos of the progress while we were at work, which we really appreciated. We've already recommended Carl to two neighbors.

Quality work, fair price. Carl and they swapped a sketchy Federal Pacific panel for a modern one in a single day.

Five stars all the way. Carl and they added recessed lighting through the entire main floor and patched everything beautifully, and they took the time to answer every question we had. If you're on the fence, just call them.

Wow — what a refreshing experience. Carl and they ran new dedicated circuits for our home gym in the basement.

Dependable and easy to work with. Carl swapped a sketchy Federal Pacific panel for a modern one in a single day, and the whole crew sent us photos of the progress while we were at work. They also offered three different options at three different price points, which we really appreciated. Highly recommend with one minor caveat — but no big deal.

Started strong and faded. Carl and the crew ran new dedicated circuits for our home gym in the basement, and they called the night before to confirm. We'd think twice before calling them again.

Wanted to like them more than we did. Carl and the crew added recessed lighting through the entire main floor and patched everything beautifully.

Would recommend to friends. Carl and they installed dimmers and smart switches throughout the house, and they showed up exactly when they said they would. Highly recommend with one minor caveat — but no big deal.
