Get matched with top electrical wiring or panel upgrade pros in Mayville, WI

"Arrived on time, replaced electric plug, tested new plug, all work finished in less than 20 minutes"

"Randy was not only a knowledgeable and competent electrician, but an honest and ethically person. Our A/C and furnace appear to have no power. The main panel was looking pretty rough. Randy came by on a Sunday to take a look and quote a replacement. He inspected the system and concluded that it was working properly with cosmetic issues. He could have been dishonest, he wasn’t. He could have left, he didn’t. He moved on to the furnace and discovered a bad fuse, replaced the switch. It worked, but not the A/C. He could have left, but he didn’t. He went outside and tested the fuses and box, good. He unscrewed the cover on the unit and as he went to pull the cover the fan came on. What! An electrician with magical powers? One who can will dead appliances to life? A super hero? Maybe, but there was also a loose wire. Bottom line, Randy saved us a significant amount of money. Grateful for his service."

"Boy Scout Service: trustworthy, helpful, friendly, courteous, kind, etc. Installed 50A outlet. Since he was here I had him look at some other work to bid on (remove baseboard heater and install outlet). He moved his schedule around and got it done the same day, going out of his way to save me money. I'll be calling Cornerstone in the future!"

"Great experience! Our electrician Adam was amazing. We contacted them, Adam showed up the next day and fixed 4 separate projects in a couple of hours. Worked fast and did great work in identifying and solving a few issues that have been troubling us for years."

"They don't use the same contractor. You don't always get the best. It's cheaper for major repairs. They cover everything, parts, labor."

"Chad did excellent work and did not exceed his quoted cost. He also did other minor upgrades to make my house safer and closer to code."

"Nic was professional, courteous, and ensured that I was happy and satisfied with his work. I would definitely hire him again to help with my future home projects."
