Window Replacement FAQs

How do I choose the right windows for my home?

When thinking about replacing your old windows, there are a number of factors you should consider to help make the best decision. Appearance, performance and durability are all important. A weighted balance of product quality, service, and warranty add to the overall value of your window replacement project. With a wide variety of window options including frame materials, glass coatings, operating styles, and installation methods, it can be challenging to decide what window is right for you. Our project consultants will guide you through the product selection and ultimately work directly with you to find the right solution for your home.

 

What are the window frame and sash made of?

All of our Renewal by Andersen® windows are made of a wood/c-pvc composite product called Fibrex. We offer one of the only true composite windows available.

Do you have the right style of window for my home?

We have a complete line of windows that includes everything from traditional double hung windows to specialty roundtops and shapes. Our offering is not only comprehensive for window styles, but we have the ability to make special grille patterns or custom-size shapes. And all of our windows have a similar finish and profile, so if you choose to change shapes, we’ll be able to make things fit back together.

How energy efficient are your windows?

Our windows are Energy Star certified in the Northern climate zone. You can find out more information about individual window performance from one of our project consultants or by visiting www.nfrc.org.

What is your window warranty?

We’re proud that our windows are backed by Renewal by Andersen® and includes 20-year glass, 10-year parts, and 2-year workmanship coverage. You can read our window warranty anytime here.
