Windows Cost Estimating Tips

As with all doors to be included in the project, all windows should be listed on the drawings in a window schedule. If none is included, it may be well worth the time to create one. The schedule should contain the opening number, window type, window size, glass type, frame material and details, and required accessories and hardware. In addition, energy ratings and window films should be reviewed. As with the door schedule, making a copy of the window schedule can expedite the quantity takeoff.

Metal windows - Most metal windows are delivered preglazed. However, some metal windows are priced without glass. Read more about estimating glazing.

Wood windows - All wood windows and vinyl are priced preglazed. The glazing is insulating glass. Some wood windows may have single pane float glass. Add the cost of screens and grills if required, and not already included.
