Michael CunninghamMichael Cunningham ★★★★★ Jeremy installed a Hot Water Heater at our residence yesterday.Jeremy was super friendly and professional.Did a great job! Thanks.Response from the ownerThank you so much for your review! We appreciate you calling C-U Trade Services to install a new water heater. Call us again if you have any plumbing, HVAC, electric or construction needs! Ronald GreenRonald Green ★★★★★ Tyler Crowl was my project manager and he was super. I had some health issues that created some unique requirements. Tyler was able and willing to accommodate all of my special needs. He even went above and beyond for me on some of those needs. He seemed masterful at coordinating the different work crews to be at my place at the right times, so as not to be in conflict with each other. There were a couple of days at the end of my project that required more than one work crew to be working at the same time. When that happened, the work crews were very accommodating to each other. There was no " how can you help me" , but rather, " how can I help you " to get the job done. A big shout out goes to Nate, Randy, Ryan, Korbyn Fatammia, Jacob, Owen, Brandon, Mark, just to name a few. Chad Detamore was my initial contact with CU Under Construction. He came to my place to see what I wanted done and to then work up an estimate. He worked with me from start to finish to see that the project stayed on budget. Kudos to Chad for all of his work, that resulted in my project actually coming in under budget. That's right, UNDER budget. Courtney and Christina were very helpful in keeping the communications, with regards to any changes I wanted done, and the resulting cost difference, open. For all the above reasons, I would, without any hesitation, recommend CU UnderConstructionfor any project a homeowner wants done.Response from the ownerMr. Green, We showed your review to our entire management team and one was even moved to a tear. We are so proud of our team and it was so thoughtful of you to name everyone and to detail out your experience and what made it such a good one. We are so happy we could help you and it was a true pleasure working with you. Thanking us in a public way like this really helps us more than you know, and we truly appreciate the time you took to do it. Tyler has been here a long time and we truly appreciate all he does for our clients. We made sure he read this as well. Thank you again. Shannon DeLaMarShannon DeLaMar ★★★★★ I have called CU Under Construction in the past for roofing,siding and gutter replacement work relating to hail damage. We were so satisfied, we called them for some remodeling--replacement of french doors which ended up being a bit more work than we thought because we needed to replace framing and one support beam and they did a great job diagnosing and addressing the issues. I trust their diagnoses, workmanship and expertise. Everyone we have dealt with was helpful, skilled and did a great job. Most recently, we had a dishwasher motor leak cause water to leak into our cabinet boxes. Upon removing the damaged cabinet boxes, they found damaged drywall, kept us and our insurance adjuster informed and did a great job. They were on time, professional, friendly and skilled. They listened to specific concerns I had and then replaced the damaged drywall, cabinets while taking precautions so as not to cause any health issues for our family members. Through no fault of theirs, a countertop arrived damaged and so they made sure we could use our kitchen until an undamaged countertop arrived. We highly recommend Cu Under Construction!Response from the ownerShannon, Thank you so much for your continued business and for your kind review. This is exactly why we have built a company where we have the trades in-house. We want to be. your trusted go-to for all things home related and know that when you call us we will do our very best for you. We are so glad to have you as a client and look forward to helping you in the future. We can't thank you enough for taking the time to leave us a review. Dee HucalDee Hucal ★★★★★ MY HOUSE HAD FLOODED!! I called a construction company in town that was doing a lot of advertising since they merged their business. They did come out and talk to me about doing repair work but I couldn't get them to return my calls with additional questions. If I couldn't get them to return phone calls, why would I want to do business with them?Someone had suggested contacting C-U Under Construction. I had no experience with them and no knowledge of their reputation in CU. It turns out that their were an excellent choice to do what I needed to get my home back in pre-flood condition.ADDISON BOYD came out to see what I needed. He was very pleasant and highly experienced. He thought of and suggested things I might consider for the repairs. As I had no experience at flood repair and insurance claims his insights were extremely helpful. I sensed his customer care and felt he was concerned with the correct kind of work needed and the quality of that work. I read reviews on C-U Under Construction showing just those standards.Their company took over coordinating old flooring removal, furniture move out and in, floor installation with Flooring Surfaces and carpentry work. Having them tie all 3 functions together and seeing to all the details was huge for me. It gave me ONE COMPANY to deal with!!For any wood working be sure to get RANDY/CARPENTER for wood work trim out. He has a high standard of work excellence and he knows what you need even before you do. He makes sure your woodwork is professional.Finally, the Project Supervisor TYLER CROWL, he kept it all flowing together in a timely and professional way. If something needed his review, his people were right on the phone with him. He always stopped by to check on the project, answer questions, check for quality and see to any detail that needed smoothing. He can even calmly handled a stressed out homeowner! He was quick to answer any texts and phone calls. He made you feel like he had time for your needs and that you were an important customer for them. He went way beyond the normal expected work level and did some little things that made me a VERY HAPPY CUSTOMER!Response from the ownerDee, We cannot thank you enough for your kind and detailed review. We hope it helps someone in the Champaign-Urbana region who may have a similar situation in the future decide what construction company to use. We are truly glad your home is restored and that we had the opportunity to work with you. Heather THeather T ★★★★★ I can't thank C-U Under Construction enough for the beautiful job they did on our new multi-level composite deck. From the first consultation until the completion of the whole project, I was given excellent customer service and communication. Tyler had a can-do attitude when I told him about my ideas, and he made our vision a reality. He was able to present a 3D design and exact price quote, which other companies we spoke to would not offer for this complex design. Landon, our project manager, went above and beyond to handle all of the details and provided above and beyond communication throughout the project. Jeff and team were meticulous about every detail of the construction, and the workmanship is superior to anything I've ever seen. Every single employee, from the electricians to the guys who picked up the equipment, were wonderful and professional. The finished project and the whole experience exceeded our expectations by far. We have already signed up to have our next project, new siding, completed by the C-U Under construction team. Thank you!Response from the ownerHeather, Thank you so much for your review and for choosing us to work on your project. All of the crews, managers, and sales team have nothing but great things to say about working for you. It is truly an honor to transform the exterior of your home and we love backyard you have created. We are so grateful for your business and kindness. - Sincerely, The entire CUUC team! Jason BuchananJason Buchanan ★★★★★ I had an excellent experience with CU! I highly recommend asking for Jarrod Brant, he was incredibly knowledgeable and made sure all my questions were answered. He went above and beyond to make sure all my needs were met, which made the experience so much better.Response from the ownerThank you so much for your review, Jason! Jarrod is a wonderful Project Manager and we are so glad that you had a great experience. Thank you for choosing C-U Under Construction. Judith MillerJudith Miller ★★★★★ CU Trade Services recently put in a new AC unit for our rental house when the old one suddenly broke. They came fast when we needed help and all the employees we dealt with were great.We also just had new countertops installed in our kitchen we purchased through CU Under Construction. Again, we couldn’t have asked for better service and the templater and installers did a super job and were very nice guys to deal with.Response from the ownerThank you very much for your kind review! We appreciate your business. Dan MalinowskiDan Malinowski ★★★★★ Jeremy has been at my rental properties several times. He has done quality plumbing work and is very friendly to my tenants.

Bob BennettBob Bennett ★★★★★ My wife and I are so very pleased with the remodel of our four season room provided by the terrific professionals at C-U Under Construction. With leadership by Jarrod Brant, our Construction Project Manager, the project was guided through many challenges, and we're so proud of the result. We are fortunate to know and will always appreciate the friendly, dedicated, and caring team of wonderful people at C-U Under Construction.Response from the ownerWe are so pleased to hear about your remodel experience and that you are pleased with the team! We feel the same way about clients like you- a joy to work with. Enjoy that beautiful four season room! It was an honor to make your vision for the space a reality. Thank you for choosing us. Scott RemoleScott Remole ★★★★★ CU Under Construction has been fantastic to work with! Have used their HVAC service and couldn’t be happier. I purchased an ecobee thermostat and my set up only had 4 wires and the ecobee called for 5. I hired CU to come out and replace the wire and they had an alternative solution for the wiring which saved me hundreds of dollars! On top of that, my sensor that I purchased with the ecobee was bad and they took it for me and filed a warranty replacement on my behalf even though I didn’t purchase the unit from them. I’m a customer for life!Response from the ownerThank you for your review, Scott! We are so glad to have you as a customer. We are here for you for all of your home improvement and maintenance needs!

Emily Bruns-HagaEmily Bruns-Haga ★★★★★ CU Under Construction installed a little under 100 front doors for our property last summer in just under a week. They were quick, proficient and very easy to work with. They communicated with our residents effectively and handled all their questions in a timely response. Really looking forward to working with them again.Response from the ownerThat is a lot of doors! We enjoyed working with you very much. Thank you for taking the time to leave a review! Matthew BarcusMatthew Barcus ★★★★★ They called me back quickly in regards to getting a estimate set up.Linda AthertonLinda Atherton ★★★★★ The craftsmen at C-U Under Construction, especially Jarrod, did a wonderful job on re-creating my master bathroom. They are very professional and did a meticulous job. This was especially difficult with the Covid pandemic and the unexpected delays that brought to the project so although the project took longer than expected it was completed to a beautiful finish that was worth waiting for.Response from the ownerLinda, Thank you so much for your review. We appreciate your understanding during the COVID climate so much. We agree, Jarrod is very wonderful Project Manager to work with. Your bathroom is absolutely stunning.

John GallagherJohn Gallagher ★★★★★ We had them paint a room, fix our roof, put on a new roof, and do several small jobs around our house over the course of a few years. Highly recommend.Kevin CashKevin Cash ★★★★★ I had roof hail damage from a freak summer storm. Zach made the process simple, painless and extremely easy. The office staff was always on top of things and informed me about deliveries and when they expected to start the project. During the project the crew worked quickly, efficiency together. Zach, the sales rep, stopped by 4 or 5 times during the project checking in to see how things were going. I ended up needing all new sheeting, Zach reached out to my insurance agent for me and worked with him to pay for the sheeting. Overall I was VERY VERY pleased from the beginning of the quote to the completion of the job. I would recommend these guys to my friends, my family and to ANYONE.js_loader
