Zen Windows is a revolutionary window replacement company based in Milwaukee and serving a large portion of southeast Wisconsin. Our goal is to provide a hassle free experience throughout the entire process (from quote to cleanup). Rather than adhering to the traditional, outdated model of sending a salesperson to one's home we instead offer accurate quotes via email or a phone call. And we simply email everything else needed to make an informed decision (PDF brochures, video product demonstrations, etc). Enjoy the unique experience of working directly with the owner of the company to meet your window replacement needs as well as the piece of mind of a transferable lifetime warranty, and a no down payment policy.
