Why Choose Renewal by Andersen?

Twice as strong as vinyl, Fibrex® material means weathertight seals stay weathertight. Its durable nature means that it can stand up to even the most extreme temperature swings, maintaining its stability  in all climates.

The strength of Fibrex® material means narrower frames; narrower frames mean more glass—and more view. Plus, the extrusion process allows us to craft your windows to any shape—meaning you can match the architectural style of your home…or define a new look.

The process also fuses the color into the material, offering you a wide palette of long-lasting colors to choose from—including dark exterior colors not found with most other replacement windows.

Your Renewal by Andersen® windows are warranted not to flake, rust, blister, peel, crack, pit or corrode. Plus, our windows stand the test of time and are as easy to operate after 20 years as the day they were installed.

Our 4 Step Process

1. Consultation

Our design consultants listen to your needs and create a plan to improve energy efficiency and enhance your home’s beauty.

2. Manufacturing

Your Style. Your Home.

Improve the Energy-Efficiency of your Home

All Renewal by Andersen windows are custom-made for your home with our proprietary composite Fibrex® material. Fibrex® material combines the best qualities of wooden and vinyl windows to protect your interiors for years to come.

Our frames are made with 40% reclaimed wood fiber by weight and composite plastic polymers. This provides twice the strength of vinyl windows to hold large panes of glass with narrower frames. Plus, our Fibrex® material opens and closes easily so you can make the most of your Spartanburg or Greenville, SC area scenery.

Renewal by Andersen functional and stationary windows are also guaranteed to last longer than standard wooden of vinyl windows. Use your new window often and in any climate to enjoy years of seamless function—without bending or bowing. All Renewal by Andersen windows are also backed by a 20-year warranty regardless of climate, type, and style. Guaranteed.


I love my new windows, made a HUGE difference in the drafts, keeping wind noise out, and keeping heat in. I also choose a different style and the view is much nicer, easier to open and close

The Value of Replacement Windows

When you’re faced with a large home improvement project, such as getting new windows, it’s not uncommon to ask, “What’s the real difference between these companies?” or “Just what AM I getting for my money?” We believe it’s good to ask tough questions because it allows you to make a well-informed choice. We want you to know the value of what you are getting when you choose Renewal by Andersen Signature Service—both in the short term and the long.

How Much Do Replacement Windows Cost?

Window prices depend on a variety of factors, and no one can give you an accurate estimate without assessing your situation in person. Some of the most common pricing considerations include:

  • Window type
  • Window size
  • Hardware and other features
  • Installation techniques

Some companies offer low-priced window construction and installation, at the expense of long-term performance. Opting for a cheaper window now could mean you are paying more for another set of replacement windows 5 or 10 years down the road. Our windows are warranted to stand the test of time, and we’ll stand behind them—giving you the peace of mind you deserve with a long-term investment.

Schedule a free in-home consultation to learn more about the true cost of replacement windows.
