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.
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.
