When evaluating and comparing window warranties, consider these questions:

• Does the glass breakage warranty cover all tempered and specialty glass?
  
  
• Is the warranty limited or a full lifetime warranty?
  
  
• Is the service worked performed by factory trained technicians or sub-contractors?
  
  
• Is labor included for the length of the warranty?
  
  
• Is there an overwhelming amount of paperwork to deal with?
  
  
• Are there hidden costs or fees associated with the service agreement?
  
  
• Is the warranty easily transferable?
