The Importance of Proper Window Installation

Replacing your current windows is an important project you want to entrust only to the pros. That’s because a do-it-yourself project, or working with amateurs, can cost you more money in the long run. Window replacement is an activity you want to get right the first time. Renewal by Andersen® of Central Illinois explains why a flawless window installation is crucial to the performance and longevity of your new windows, as well as to the comfort of your home.

Energy Efficiency

Windows, as part of your home’s thermal envelope, keep your living space cozy all year round. A poorly installed window can undermine the comfort level of any room. Fortunately, our company follows a precise start-to-finish replacement process, so rest assured that our crew will take care of the job for you. That way, you can enjoy the benefits of our thermally efficient replacement windows.

Our company uses advanced High-Performance™ Low-E4® glass that is 45% more energy-efficient in summer and 56% more energy-efficient in winter. This standard glass offering can help drive your utility bills down.


With the right replacement windows, you can enjoy a more aesthetically appealing interior and exterior space. Your new windows can boost your home’s curb appeal by creating a bold statement. Your local contractor will help you pick the right one that can complement your home’s architectural design.

"I would recommend RBA of Central Illinois for QUALITY windows and doors. Compared to our old cheap, thin vinyl windows, Andersen blows them away. You can easily tell by how well the sliding doors fit and close, and how heavy duty they are. We also cannot hear the wind rushing through the house in inclement weather anymore! And the black window frames we went with are amazing to look at. Aaron, Al, Darrell, and Cory all were professional and went all out to finish the job, given the weather they had to deal with. I would definitely recommend. They were also on top of communicating with me given the weather delays, and what I could expect for them coming out. Five stars!"
