Window Replacement Contractors in Oconomowoc, WI

"Mad City installed about 15 replacement windows in our home. They showed up on time, were efficient, and returned for quality inspection and minor repairs needed. Very happy with the product and itâ s efficiency especially this winter season. Hope to have them return to replace other half eventually."

"Very professional, polite and kind workers, and the owner of the company checked on the progress and quality of the installation."

"We actually had a problem with one of the windows, which was no fault of Window Concepts, but the manufacturer themselves. The purpose of me mentioning this is because it was addressed by Window Concepts Immediately and although we had to wait a couple of weeks for a proper replacement, it was taken care of. We were never left without a window or anything, we just had to make sure the window was always closed and locked before we left the house. But, who doesn't close and lock their windows when they leave the house? It was not an inconvenience , and it was taken care of as a priority. From day one and the sales man I worked with, Mike, through the measuring and installation, with Buzzy, to arranging the reinstallation of the manufacturer defect with Rick at the office, and the woman that answers the phone at the office, VERY PROFESSIONAL and always treated me respectfully and courteously ."

"Cris is great! We have gone with Champion prior and we called specifically to have him come back out when we needed to replace our picture window. He is great at explaining everything and answering questions. 10/10 would recommend him if you are going thru champion."

About us: "Making complicated simple."

"During our recent episode of -26-degree weather, one of the panes of glass in our 16 yr. old, large Stanek 2 lite slider, experienced and thermal shock and cracked into many pieces. We taped the larger pieces in place, and called Great Day Improvements LLC, the current representative for Stanek windows. They were very pleasant, and immediately set-up an appointment for Josh Haas, their Service Manager, to come out and inspect it. When Josh came out, we were very happy to see what a nice and knowledgeable person he was. He explained what caused the thermal shock and said that it, plus two of the other panes with seal failure, would be covered by our Stanek warranty. When we asked if the new windows would have a different hue, he said yes, because of the different film in the window. We asked how much it would cost to replace the window that was OK, and he said that he would find out and call us when he got back to the office, and he did. We decided that it was a fair price, and told him to order it as well as the ones that were under warranty. They kept us informed about when they were manufactured, when they would get here, and set up the install appointment. When Josh came to install them, we found out that not only is he a very nice person, but he is a very careful and skilled craftsman. He did not lose a single piece of glass from the broken window when he took it out. He made no mess and even cleaned the new windows before putting them in. Josh is just outstanding, and we can not say enough good things about him!!"

"This project started out as an inquirey to install an awning and ended up as a fully enclosed porch. Very happy with the result. I would recommend this company to anyone."

"Mike Miner was my sales rep, he was amazing and so down to earth. My installation guy was Emilio, he was thorough, quick, energetic, friendly and put all 9 of my windows in on his own. Took about 9 hours. Great clean up and great customer service and communication from the office! I get so many compliments on my windows from neighbors!"
