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.

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!
