Windows are one of the most important features to a building, as they are able to offer both natural light and ventilation. Window design and technology has come a long way in the past few decades, and replacing older windows with new ones can offer a wide range of benefits, from energy efficiency to durability and long life. With the different styles and types of windows made today, estimating their replacement costs is a generally easy task and is the best way to plan a budget and avoid costly surprises.
Measure the height and width of a window that is to be replaced.
Write down the window dimensions, listing the width followed by the height (both feet and inches).
Note the window type (swing, fixed, etc.) along with its dimensions.
Repeat steps 1 through 3 on the rest of the windows to be replaced. You can use tally marks for multiple windows of the same size and type.
Call a local door and window store to quote the current price for the windows on your list and their delivery and installation costs, and add the prices to find the total cost of replacement windows.
You may also need to consider any costs of repairs to the structure surrounding the window (window frame, window trim, etc.); these costs can vary greatly from house to house, but in some cases may not be known until the old windows are removed. To avoid window disposal costs, you may try to contact a local used building supply centre and offer your old windows.
