Warranty service claims are supported through the purchasing dealer. It is strongly advisable to know the following information:

  • Manufacturer
  • Order number
  • Year of purchase.

If you do not have this information, there is a “bug” in the corner of the glass that is a unique identifier for any window and door. Checking the hardware for manufacturer name is another technique we recommend.

Having a record of your Manufacturer’s warranty is extremely important, so that the terms of warranty are followed. Oftentimes, at the 10 or 20 year mark, a warranty for materials ONLY is expired. If the product is out of warranty, we can help you determine if the best recourse is to purchase a new window or door, or if you need a company that specializes in servicing and replacing parts for window and door hardware.

If we are not the original dealer who sold your product, our hands are tied for warranty service claims as we do not have a record of your order. Also, if you are beyond the warranty period, the manufacturer will not provide materials.
