Wyatt Madej
I had a great experience with C-U electrical while they installed an EV charger and performed a panel upgrade and sub panel installation. I worked with Jaron during the planning phase who was communicative, thorough, and even made me aware of cost saving programs from Ameren. The onsite team was professional, did a great job, and left no trace besides the great upgrades over the course of two days.
Response from the owner:Thanks, Wyatt! We’re glad Jaron could help during the planning phase and point you toward the Ameren savings programs. It’s great to hear the team took good care of the EV charger install, panel upgrade, and subpanel work. We appreciate you taking the time to share your experience.

Called CU Under Construction for a leak in my crawlspace. Curtis and Mitchell came within two hours of calling and completed the service in less than an hour. Another plumbing company looked at it before CU Under Construction and said they did not have the capacity to fix the problem. I will continue to use CU Under Construction for whatever problem I have at my home in the future. The price for repairing my leak was extraordinarily reasonable, and I was happy to pay every penny. Thank you see CU Under Construction.
Response from the owner:Thank you so much for your kind words! We're thrilled to hear that Curtis and Mitchell were able to promptly address your leak issue and provide exceptional service. We're dedicated to delivering quality work at reasonable prices, and we're grateful for the opportunity to help! Looking forward to working with you again in the future!
