Window Replacement Companies in O Fallon, MO

"They did a really good job."

"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."

"Jeff is absolutely wonderful, we were so fortunate to have made contact with him! We had Jeff do a complete kitchen and two bathroom update project, he also has replaced our entry and storm door, installed a Ring doorbell system, replaced exterior light fixtures and installed new exterior electrical receptacles so we could plug in de-icing mats over our entry walkway. He takes a personal interest in our safety (aging seniors) and our projects that we have lined up. He provides great follow-up with any issues, and we have recommended him to family members who have reported back with the same great experience with Jeff. I have a constant running "to do" list for him, and the next project is window replacements, but I will insist that he wait for better weather. Even though he is willing to work in the cold, we respect him as much as he respects us!"

"Wow! These guys are exceptional. They gave me some great advice on changing the look of my bay window. Instead of giving me a quote for exact replacements, they suggested that I replace the middle double hung windows with a large picture window and the two side double hung windows with casement windows. The difference is INCREDIBLE. It totally opened up that bay window to my beautiful backyard. I would HIGHLY recommend these guys!"

"Fast friendly service"

"They installed windows for us. We found one window that was barely cracked. They came right back out and replaced it right away. The windows are very high quality and they are easy to clean. It so nice to have the new windows!"

"He showed up on time and did a great job."

"Gary and me walked around my house, he pointed out the windows that needed to be replaced, He was truthful in what he can do, How long it would take, Did a Great job. Was done before, before he said. And installed the before he went to his sons baseball game. What a Champ. Very happy with his work, will call him if I ever need my screens replaced."

"Rodney and his team - Tyler, Joey and Jordan - did an outstanding job removing and replacing our 17 windows and patio double door. All were very careful to ensure no damage to paint, woodwork and flooring when removing the old windows. All new items were installed square to their original frames, and all four sides of every item were carefully inspected and very well-sealed with caulk and insulating foam. The entire effort - 5 1/2 hours from unload to cleanup - was so efficient that we're certain an additional team member was in hiding somewhere! We are exceedingly pleased with the quality and price of our Universal Windows Direct products, and are absolutely amazed at the diligence, courtesy, and professionalism of this team. We highly recommend the Universal Windows Direct products and the professional work of Rodney, Tyler, Joey and Jordan. Thank you for your outstanding services!"

"Larry came out and quoted us on our insulation needs and explained in detail what was needed and why it was needed. Most companies just tell you what you need without ever explaining why. We also had some odds and ends with an attic fan replacement and a ceiling fan that needed to be installed which they also could do. Even though their name specifies basements, they can do about anything. Once the project started, it was 100 degrees outside and I was afraid that with the heat they would rush through the situations, but they did the job to perfection and were absolutely great to work with. I would recommend them to everyone and for everything"

"AJ was the best contractor we have worked with. I would use him again"
