"We hired Alex to install can lights in our dining room. The price was extremely reasonable and they were able to fit us in within a week of when we received their quote. They arrived promptly, installed in a couple hours and had the room as clean as it was when they arrived. We plan on using Power Electric again to upgrade our fuse box and also to hang more lights. Very pleased with the overall experience. Highly recommend!"
