Jeremy has been at my rental properties several times. He has done quality plumbing work and is very friendly to my tenants. If I have any future problems I will be sure to call CU Under Construction.

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.

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!

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.

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.

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.

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.

Jeremy Janes and CU Under Construction did an excellent job on rebuilding a chimney and replacing my roof and decking in April 2020. I was referred to CU Under Construction by several friends and contacted them for an estimate on a complete rebuild of my chimney due to water damage. Jeremy was very responsive and had an estimate back to me quickly. While he was inspecting the chimney he found hail damage on my roof and worked with my insurance company directly to get my entire roof and decking replaced and fully covered by insurance. It was incredibly smooth and low stress thanks to Jeremy's attention to detail. I have worked with contractors before and none have left my house as clean as CU Under Construction when they left! Jeremy was responsive, communicated often, highly professional, followed through on exactly what he said they could do, and managed the project well so that I have full confidence in the quality of the work. The next time I have a project for my house, Jeremy is the one I trust to help me figure it out. I highly recommend Jeremy Janes and CU Under Construction.

The service and price were both excellent! Our AC went out during 110+ heat wave and they came out within 6 hours of calling for an appointment. Andrew from CU- HVAC was very professional and had the problem fixed in 30 minutes. I will definitely use them again!

C-U HVAC division! My A/C died and I got 3 quotes. In having an excellent experience with C-U Under Construction previously, asked their HVAC division for a quote. It came in as very competitive and I signed a contract. The diligence/dedication/professionalism of Jeremy and his team has made me KNOW... my air conditioner investment was placed in the best possible hands. Kudos and Thanks!
