Window Identification & Warranty Stickers
When cleaning a new window, it can be tempting to remove every sticker or label you see. Before removing a sticker that is hidden inside the window, check what it is. Many manufacturers place identification labels in areas that are not normally visible, such as along the side or top of the sash, inside the frame, or in another concealed location.
Why Should I Leave Hidden Window Stickers Alone?
These labels can contain important information that may be needed years later to identify the exact window.
Manufacturer
Window model or series
Size
Glass information
Manufacturing or order number
Production date
Product or serial number
Why Does This Matter Years Later?
A window may last for decades, but identifying the exact window years later can be difficult. Balances, pivot bars, locks, tilt latches, glass packages and other components can look very similar while actually being different. A manufacturer's label can make it much easier to order the correct replacement part, glass unit or sash.
What About Warranty Claims?
The information on a hidden label can also be important when contacting the manufacturer about a warranty claim. Even if you keep the original paperwork, leaving the manufacturer's identification label in place gives you another permanent source of information about the window.
Which Stickers Can I Remove?
Temporary shipping stickers, installation labels and stickers placed visibly on the glass are generally intended to be removed after installation. However, do not automatically remove labels located in concealed areas of the sash or frame. If you are unsure what a sticker is for, leave it in place or take a clear picture of it before removing it.
A Simple Rule
If you cannot normally see the sticker when the window is closed and operating, there is usually little reason to remove it.
That small label may make finding a replacement part or handling a warranty issue much easier years from now.
