About Us

In 1954, when contractor Roman Steffes started building his first home in Carroll, Iowa, he installed Andersen® brand windows. Some 600 homes and more than sixty years later, Roman is still using Andersen windows in his new homes. When two of Roman’s sons, Dave and Tom, established The Steffes Corporation in West Des Moines in 1996, they naturally partnered with the window brand they had grown up installing: Andersen.

"We are very pleased with the Renewal by Andersen Company we worked with and the finished product. From the sales representatives in the show room, to the installation, to the trim and staining of the trim, to the service, we are extremely satisfied. All of the persons we worked with on this project were very professional. We'd recommend RBA to anyone. Our installer was Craig."
