"I hired Kyle to install the electric for my pool. He grounded the pool, installed an electrical timer for the pool pump, breakers for the circuits, and installed an outlet. I liked the quality of the work so much that I hired him to replace a GFCI outlet in my kitchen and an exterior outlet on my house and then hired him once more to install light fixtures. His prices are fair and his finished product is meticulous. If he tells you that you need something replaced/repaired he is not saying it to make money, he is saying it because the repair/replacement is necessary for safety or code purposes. I would hire Kyle again for any of my electrical repairs/installations."

"Hired HomePro Electric to install a transfer switch for a portable generator. Erik did a great job. Showed up on time. Did an excellent job and explained how to switch our electric panel from the grid to the generator really clearly. I will definitely hire him again for any future electrical work that I need."
