Edited review coming soon.... (11/6/2026) Satchel came to our home and explained everything, answered all of our questions, was friendly, and professional. He is a man who loves his job and company, and it shows through his attitude. He measured all of the windows to the 1/8", not 1/4". He did NOT berate other companies- he let the windows speak for themselves. High 5 and highly recommended!

Referred to Mad City via a friend. From sales to install, they were thorough and professional. Although a bit more expensive than other bids, they were exceptional with their product and installation. Hats off to Alex, the installer. He worked so hard and made sure we were happy before he left.

They took out our shower tub combo and they installed a walk in shower. It looks amazing. It's like you just walked in to a fancy hotel shower but it's ours. Install was a success and went very well.

I just had a shower remodel with Mad City Windows and Bath. My experience with them was exceptional! From sales (Anthony R.) to installation (Lon A.) everyone was very professional, informative, courteous. Lon cleaned up the bathroom beautifully when the work was completed. The workmanship is top notch!

If you are lucky enough to get the salesperson Matt you will be in the best hands. He is a God fearing person. He's not going to sell you an overcharge you if he knows you can't afford it he'll say this will do the same work. He is exceptional. Actually to be quite honest, he's the best salesperson I've met in my whole life and I never give out compliments often and I never do reviews this is my second review ever. I hope you're able to get one of mad City windows and a bath. When Matt tells you that his boss is awesome and all his colleagues are wonderful too and they hang around like family, the company to go with. And look they've been around for years. I would highly highly recommend.

Had 5 windows replaced, while not the cheapest out there, I believe that the warranty they give of replacing the window no matter what happens to it not only for me but the next owner, made up for the cost. I had two other windows replaced by them three years earlier and they kept us warm in the winter and cooler in the summer. The crew were fast and friendly and cleaned up after them selves when they were done. Overall I’m very pleased and recommend them highly.

From start to finish we loved working with Mad City. I was stopped by Mad City in Sam’s Club in Janesville, usually I don’t engage with marketers like that but they happened to catch me on a good day and redoing our bath tub has been on a list of home improvements since we purchased our home. They had me scratch off a promotion ticket and I got a 60% off install, which helped incentivize me to actually schedule and in home estimate. Our in home estimate was great, our sales rep walked us through everything, was SUPER thorough, and helped us figure out what was right for our needs. Our product came almost exactly 6 weeks later, they scheduled our install within a week of our product being finished. Our install team arrived at 8:15am and they went through the project details with me before they got started, consulted me on placement of cosmetic features of our tub, and were finished with installation by 2:15 same day! They took their time to make sure everything was perfect and ensured we were satisfied with our product, spoiler… we are! I would HIGHLY HIGHLY recommend Mad City for your bath needs!

We had Mad City replace our shower Tuesday October 20 2026. Our sales person was Kevin. He was professional and very respectful without being pressuring at all. Once our shower came in we were put on the schedule. The installer came out by himself the first day and had the old shower ripped out and the new shower installed. He was also very accommodating and respectful. The second day the installer had a helper who was also very respectful and accommodating. They finished up in short order. Our shower head was shipped with the wrong color attachment which was replaced the next day. After a couple showers we needed our shower temperature adjusted. We were put on the schedule for the next day. Again the gentle man who came out listened to our concerns and made the adjustments. We could not be more pleased. We were kept informed every step of the way. Every person we had contact with was extremely professional. I dont know if we got a good deal or not because this was the only company we got an estimate from. I know for me its not only the cost of the product but the professionalism the company instills in its employees that has as much to due with the price of its products. I would recommend them to anyone who asks me.

The sales rep was helpful and straightforward with information, and pivoted the sale without question when I inquired about doing a bathroom instead of the kitchen. Installation tech was precisely on time, and very quick and skillful - I can hardly tell where the seams are in the acrylic. As a bonus, no AI answering system when I did have to call corporate for information. Real people with real answers.
