Our Promise


Your home is the center of your world. It's where you make memories and share time with your family. When it comes time to make improvements, you shouldn't take chances with your results. From deciding on which style of window you want to figuring out who will install them, you should be confident that you are making the right choice for your home. At Zephyr, we've been improving homes in Eastern Iowa since 1951. When we became the exclusive local provider of Renewal by Andersen replacement windows in 2004, we knew we were providing our customers with the best windows and patio doors available.

We're proud to be part of the family of companies that make up Andersen Corporation-a name synonymous with quality - and are committed to providing you with an exceptional replacement experience. We look forward to showing you the Renewal by Andersen difference that sets us apart from our competitors.

•We promise to treat you, your family and your home with utmost respect.
A team is only as strong as its individual members, which is why we hire the right people from the manufacturing employees to our project consultants to our installers. Everyone goes out of their way to make sure you and your home get the respect you deserve.

•We promise to listen to your needs and recommend the best solutions for your unique situation.
Before we ever set foot in your home, we have already talked with you about your home and your project. Great customer service is about listening to the wants and needs of your customers and from our very first interaction, we want to make sure that our product and service will fit your needs and expectations.


•We promise to custom craft and install your windows and doors with unmatched precision and care.
We measure each opening twice to ensure accuracy in ordering a window that's made specifically for your home. If your project requires custom staining, our project consultant will take a sample and our master stainer will match your existing woodwork exactly, making your new windows look like they've always been in your home.



•We promise to clean up when we're done, so you won't even know we were there.
A big part of respecting your home and property is keeping it clean. Our installers are very careful to use drop cloths and remove their shoes, when necessary, so that when we leave, the only difference you notice is your new windows.



•We promise to resolve any issue that may arise in a manner where all you remember is how well it was handled.
Even with the best plans, sometimes things go wrong. Because we manufacture, sell, install, and stand behind our windows, there is no finger pointing or blame shifting. We're happy to work with you to help resolve any issues that may arise in a professional manner.



•We promise to stand behind both our product and our installation.
Our warranty is written in plain English and we provide a written copy to you with your new windows. When you buy from Renewal by Andersen of Eastern Iowa, you'll discover you're buying products and services that are backed by one of the strongest limited warranties you'll find on any window or patio door, no crazy loopholes or unreasonable exemptions.



•We promise to make your project easy and exceed your expectations every step of the way.
Most of the homeowners we work with have never had to replace their windows before. Our goal is to answer all questions and do everything in our power to take the stress out of your replacement project so you can feel comfortable and confident you made the right decision.
