Factors That Affect Window Replacement Costs

Replacing old windows is an important decision. And depending on various factors, the costs can be quite significant. To prepare you for window replacement expenses, Renewal by Andersen of Montana lists the main factors that could influence your budget.

Window Replacement Costs

Type of Installation

When replacing windows, you can either opt for full-frame installation or retrofit installation. A full-frame (tear-out) installation requires the complete removal of the old window, while a retrofit installation means the new windows will be inserted into the existing frames. A tear-out generally costs more than a retrofit since the former involves more work and materials.


The pricing for windows varies depending on where they will be installed. Living room windows are usually bigger than, let’s say, bathroom windows because living spaces have greater square footage than bathrooms. Furthermore, a typical bedroom window will need to have an opening mechanism — such as sliding windows or double-hung windows. However, a hall window could be as simple as a picture window without opening. That said, the location of the window informs the size and style of window to be used, so it can influence the cost of the project too.

Double-Pane or Triple-Pane Windows

Triple-pane windows are more expensive than double-pane windows. While triple-pane windows are generally more energy-efficient than double-pane windows, triple-pane windows may not actually be necessary depending on your location. So consider your local climate because a high-quality double-pane window might just be enough for your needs. In many cases, double-pane windows can already offer the best value for your money.

"I highly recommend Renewal by Andersen. We were treated well and everything went smoothly from start to finish. The company kept in contact with me before, during, and after the installation and let me know what to expect. I'm in love with my new windows! I will be using this company again when we refinish our basement. "
