How to Start Choosing Replacement Windows

Set your budget. Knowing what you can afford on new windows is the first thing you should do. The cost can vary from about $7,000 to over $20,000 for the same size home, so know your limits.

Check with window installers in your area. The next thing you need to do is find a reliable company to install the windows. Ensure they offer windows in your price range and that they are experienced installing the types of windows they offer. You can find recommendations for installers through your local home improvement center.

Familiarize yourself with the brands that the installers in your area offer. A few examples include Anderson, Marvin, Pella and Alside. Each brand offers different styles and features, so talk with each installer about your options.

Pay close attention to efficiency ratings. When choosing replacement windows, the efficiency rating is what will help you save money on your home energy bills. For example, look for R-values of 2 or 3. The R-value measures the heat conductivity -- the higher the rating the better.

Look for other features that can make the windows more efficient or attractive. Efficiency can be improved with a low-e coating or double glaze, and tilt-in sashes make windows more attractive to homeowners because they're easier to maintain and keep clean.
