C-U Trade Services recently installed a water softener in our home, and this has made a significant difference in our water quality, with positive implications for our dishwasher, washing machine, showering, and more! Jeremy clearly explained why our home would benefit from a softener, and his installation work was outstanding. Highly recommended. I also want to note the wonderful work and fair prices I've experienced over the years for HVAC and electrical work from C-U Trade Services.

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!
