FAQ’s about Replacement Window Warranties:

What does “transferable” mean? 

Transferable means that if the home is sold, AHT Wisconsin Windows will honor the warranty for the new homeowners until the 50 years has been completed.

Most warranties are useless, what makes this warranty any better than other warranties?

Our Starmark Warranty covers the Composite Frame & Sash Members, Insulated Glass, and Hardware.  The warranty ensures that these parts are covered to stay in working order for 50 years.  What this warranty does not cover, are weather related damages, accidents, negligence, or exposure to harsh chemicals.  Most homeowners insurance covers accidents and weather related damages.  If you have more questions about this, call 888-874-9339.

Do the warranties automatically come with the purchase and installation of my windows and doors or do I need to pay extra for it?  

Yes, the warranty automatically comes with your windows and doors.  No, you do not need to pay more for the warranties.  We stand by our work which is why we are able to offer a 50 year transferable workmanship warranty.  We don’t use subcontractors so our own inhouse team or window and door installers that have been trained for quality workmanship can stand by a job done the right way.  When you are getting a in-home estimate, be sure to ask if the company offers a Workmanship warranty, any company that can’t most likely uses subcontractors and cannot stand behind the quality of their work.
