Useful information for Wallside Windows owners

windowcodesMaking a service inquiry?
Please help us identify the window at issue.

Wallside Windows made between 2003 and 2015 have unique code numbers printed on the spacer between glass panes in the upper right or left corner of each sash.  Wallside Windows made since April 2015 have unique code numbers printed on the lower right corner of the glass.   Please refer to this number which we call a “unit ID” when contacting us about a service issue.

For windows without a unit ID, you can help us by providing the following information:

  • In what room is the window located?
  • How many windows are in the room?
  • Do the windows look the same size or is the window at issue larger or smaller?
  • Does the window operate up and down or side to side?
