Edit: The shower curtain rod was installed so well it literally just saved my life. I lost my balance trying to shave the back of my leg and fell. My shower curtain caught me, and the curtain rod didn't even waiver. I'll be sore for a while, but my old shower curtain would have fallen with me and I'd definitely be in worse shape if not dead depending on where I hit my head. I had one of those one piece shower stalls with the square corner seat that took up so much standing room before. The other tubs in our house are the standard not functional depth for adults. I have chronic general all over pain, and soaking in a hot bath helps so much. When we did the consultation, I was convinced that there was no way I'd be able to get a deep enough tub in the space we have available, let alone have it feel like a relaxing retreat for myself! Joseph Brunson was our installer, he was so polite and quick! Before I knew it the shower was gone and the tub was in place. He came back the next day and finished installing the surround, and didn't even mind my excited gremlin self peaking in to see the progress! I now have a beautiful bathtub that exceeds my wildest dreams, and it only took 2 days.

From the moment we booked the visit to look at replacing a bath-shower combination in an upstairs bathroom, to the sales and contract confirmation visit, to the final installation, we were so incredibly pleased with the quality of all aspects of Mad City's work. Friendly and professional, knowledgeable and easy to understand - thorough quality throughout the process - at a very, very reasonable price. Without a doubt the best work we've ever had done in our home in over 20 years.

Excellent and professional service. Tim, our installer, explained everything in detail. Protected our floors with drop cloths, asked our opinions on heights of grab bars and shelving. We gained about 20% more shower space with sturdy grab bars all around…oh…and it looks nice too. Had a problem with some caulking. They responded quickly. Makela did a superb job and recalulked the seams. 5 ⭐️⭐️⭐️⭐️⭐️

Andrew, our salesman, made a very good presentation and explained everything so well. We had all new windows installed. Cole, Adam, and Rigo went right to work, and finished the main level. The basement windows were put together backwards. New windows were ordered immediately. Kyanne and Gregory installed them. All of the installers were knowledgeable, friendly and respectable. Eddie, Jeff and, coworkers in the Cedar Rapids office were friendly and helpful. There were a few issues, and they didn't hesitate to take care of the problems. We're looking forward to not having to put plastic on the windows in the winter. Donna and Kevin

From beginning to end the experience was professional. Troy explained everything and answered my questions. I didn’t feel pressured ant all. Caleb was awesome during installation.

Mad City did a phenomenal job on my shower. You can see the before & after pictures they speak for themselves they were here on time & never stopped working until the job was done. They were very professional & answered all the questions I had. Thank you again for the amazing job!!! FYI I had them cut my floor like this because I'm laying a new floor down & the sub floor was pretty damaged.
