J.C. Lilly Windows
Specializing in replacement windows only



"Jeannie Frankowski and her excellent, experienced crew replaced all of the windows in our home in Arlington Heights, Illinois. It wasn't the biggest job she has done, nor the smallest, but every step of the way she made us feel that our job was the most important one in the world. We could not be happier with the job that was done, and if owned a second home, we would certainly have her work there. I volunteered to write a letter to prospective new customers as a heartfelt thank you for the wonderful job that was done. We readily endorse her!"

"What we loved best about J.C. Lilly Windows was the fact they left nothing behind such as nails, screws, metal on the ground. They worked so smoothly and then they cleaned every window. Jeannie Frankowski who is the owner was on the job the whole time working alongside the installers. My mother and I were amazed. We love our new windows and  we felt that we really got our money's worth."

"I love my new front door. Love it. The front door is beautiful and the installation was hassle free. Thanks for being there for us. Wish we would have known about you when we replaced our front windows. We will definitely call when we replace the other windows."

"I had a totally positive experience ordering new windows and having them installed. Jeanne really knows her products and provided me with excellent recommendations regarding what we could buy, at the best price, with the best result.  Her installation team was great. We had a slight problem with one of the windows, and she "went to bat" for me and resolved the problem with the manufacturer, without involving me, which was much appreciated. Her installation team also fixed a window that had been installed by another contractor when they noticed it was not properly caulked; at no additional cost!  I am very satisfied with the windows too!! I recommend this company without reservation."

"My experience with Jeannie "The Window Lady" was great! I appreciated her personality and professionalism. Great follow up and follow through every step of the way. Her crew was great too. Very neat and tidy and friendly. They, along with Jeannie, went the extra mile to take care of me and my home. My 85 year old windows were replaced with energy efficient, easy to maintain windows. What a thrill to have windows that actually can be opened. I have replaced the windows in stages as budget permitted and Jeannie has been cool with that. I won't divulge her trademark thank you but it was such a surprise and wonderful touch!  What will I do now that I've run out of windows to replace!!" 

Gretchen Goode.  Chicago, IL


"I seldom give testimonials, but working with Jeannie "The Window Lady" is an experience in high quality products, seamless service and total honesty. J.C Lilly Windows and Doors installed double thick storm windows in our house on time and on budget.
