Window Function

• Single window: When it’s only one window causing you problems, go ahead and replace it. You may immediately save on energy efficiency, maintenance costs, and stress.
• Multiple windows: A single window causing issues may trigger closer inspection on other windows that may also need maintenance or replacement. They may be of similar age; however, wear and tear depends on factors including installation, usage, maintenance, and exposure to the elements.

Curb Appeal

• Single window: Switching from a dated window to one that catches your eye can increase curb appeal at a relatively low investment. This one simple, stylistic change can also give your home a focal point for passersby.
• Multiple windows: Updating every window in your home can completely transform its look. You can create a consistent style with all new windows. The expenses are higher, but so are the rewards.
  
  

Interior Aesthetics

• Single window: Many rooms only have one window, so you can enhance the aesthetic with a single window replacement. Adding a bay or bow window adds a little nook and may offer more natural light. Specialty windows and special shape windows bring character and style to make your home unique.
• Multiple windows: The upside of replacing multiple windows in a room — or your whole house — is that you create a consistent style that can be enjoyed for years. A single window replacement might seem out of place if the older windows look dated. Upgrading multiple windows can increase your home’s curb appeal and interior aesthetic, giving you the best of both worlds.
