Add Character to Your Home With Specialty and Custom Windows

Looking for a unique architectural feature for your home or need a custom window to fit a non-traditional space or wall? Turn to Lifetime for specialty and custom windows. We are the top Infinity from Marvin dealer in the nation, and we offer top-of-the-line products with a personalized touch. Our team can design custom windows to fit areas that traditional window styles can’t, and we can install special window shapes for a distinctive look.

Our Custom Windows & Specialty Windows

Lifetime installs the finest windows from Infinity from Marvin. These windows are fabricated from durable fiberglass, a leak-resistant, crack-resistant material that is eight times stronger than vinyl. You can have peace of mind knowing your new windows will stand the test of time and won’t expand or contract during extreme weather changes.

Fiberglass is crafted to look like real wood, and you won’t be limited in your design choices. We offer numerous interior and exterior finishes, colors, hardware, and glass options. Our team can install the following window shapes:

  • Octagon
  • Hexagon
  • Pentagon
  • Rectangle
  • Triangle
  • Trapezoid

We will explain our different window configurations and help you design the perfect custom windows to match your home.
