Whether you’re remodeling, getting ready to sell or building a new home, curb appeal is important. It’s how appealing your home looks from the curb not only to interested buyers, but also to your neighbors, friends and of course you!

One of the easiest and most important ways to increase your home’s curb appeal is with a new entry door. When you update, replace or improve your entry, you can increase your home’s perceived value by $18,750 on average*!

Entry door replacement consistently ranks among the most valuable remodeling projects in Remodeling magazine’s “Cost vs. Value Report,” which evaluates remodeling costs and resale value to determine which projects will give you the greatest return on your investment.**

When you consider the vast array of new styles, innovative features and bold, expressive statements that you can make with Therma-Tru doors, you can see how a new door could completely change the look of your home. Learn more about Therma-Tru front doors from the experts at GNH.
