Manufacturing & Installing Top-Quality Replacement Windows in the Chicagoland Area

Anyone can buy replacement windows from a big-box store, but the convenience of being able to pick up your product that day is where the convenience ends. And even when you contact some window companies, you may find yourself in a confusing process with windows that may cost you more than they’re actually worth for you. Want to ensure any replacement windows you buy are perfect for your Chicagoland area home? Kramer Window Company has you covered. We’re based in Maywood, Illinois and have proudly manufactured and installed custom house windows for Chicagoland residents since 1956.

What Our Clients Are Saying

Read reviews left by some of our many satisfied customers over the years:
"I had some broken window panes for pretty old aluminum triple track storm windows. Evidently this type of window is out of fashion and I had a terrible time finding a place that could help me repair or replace them. Then I somehow stumbled across Kramer Window. They put new glass into one frame and fabricated an entirely new frame for the other, which fit perfectly into my existing tracks at home. They did it while I waited and it was unbelievably affordable. Amazing find!"

"I'm a DIY kind of guy. They were of great help in manufacturing new thermo-windows for me and saved me at least thousand dollars. They do business the old fashion way, honest, quality, service!"

"I had a great experience start to finish with Kramer Windows. They replaced six basement windows in my brick bungalow. I appreciated the thorough response and estimate they gave after I requested an estimate through Yelp. The guys who installed the windows sealed the windows well and did a really nice job with the aluminum framing of the windows outside. The windows look really good inside and out and already I notice my basement feels warmer."
