The full Castle Windows door catalog can be accessed via the company’s website.

Castle Windows Lifetime Warranty

Castle Windows offers one of the most comprehensive lifetime warranties in the industry, covering more items than you might see elsewhere. Items covered in your Castle Windows Lifetime Transferable Warranty include the following:

  • Leaks and drafts
  • Vinyl
  • Color
  • Glass
  • Seals
  • Parts
  • Screens
  • Window operation
  • Colored windows
  • Installation

It is worth noting that the items included in the Castle Windows Lifetime Transferable Warranty are not prorated, meaning that all items have full coverage without decreasing in value over time. In contrast, a prorated warranty offers coverage that diminishes over time — it’s always important to read the fine print in any warranty agreement to understand your coverage and, in this example, whether or not items are prorated.

Free Online Quote

Castle Windows doesn’t provide any door product pricing on its website — this isn’t uncommon in the door replacement industry because products and installation will vary widely based on each property.

Castle Cares

While Castle Windows always strives to provide excellent service to its customers, the company also prioritizes serving its community. Through its Castle Cares program, Castle Windows has been involved in a variety of philanthropic and community service initiatives in the past, including Habitat for Humanity and CHOP. In addition, the company has arranged coat drives and other benefit events.
