The Sales Order number is the unique identification number for your product. This number is needed when filling out the service request form in order to identify your window in our system and expedite service. 

The number is located in the upper right or left-hand corner between the panes of glass. The SO # is a 5 to 8 digit number, followed by the Line Number (a decimal and three digits.) For example, a number you might see is 1144124. 002. The SO# is 1144124 and the Line Number is 002. 

Please note that some windows might not have the SO# or Line Number if made before 1995. In this case please contact customer service at 1.800.MILGARD with help in identifying your product. 

Registering your warranty is not a requirement to be covered by the Milgard Full Lifetime Warranty. However, we recommend registering your warranty to simplify your service experience, should you ever require it. 

You can wash your vinyl window and door frames with mild, nonabrasive soap and water.  First, remove any large particles (sand, bird droppings, etc.) with a soft bristle brush. Then, wash the surface using warm water, a mild soap, and a soft absorbent cloth. Wipe dry when finished. Periodic or seasonal cleaning using these steps will maintain your premium finish for years to come.
