Window Replacement Services in Glen Ellyn

FTC Oury Group proudly serves Glen Ellyn homeowners with professional window and skylight replacement services designed to improve energy efficiency, comfort, and curb appeal. Whether your windows are outdated, underperforming, or simply no longer match your home’s aesthetic, our expert team offers tailored solutions that meet your needs and exceed expectations.


We specialize in a wide range of window styles, including double-hung, casement, bay, bow, and sliding windows. Each product is available in materials and finishes that complement both traditional and modern homes. In addition to standard window installations, we also replace skylights. Skylights are a valuable architectural feature in many Glen Ellyn homes, offering natural light and visual interest, but they must be properly sealed and installed to prevent leaks and heat loss. We work with top-quality skylight products to ensure a watertight, energy-efficient upgrade that performs beautifully for years to come.

When Should You Replace Your Windows?

Knowing when to replace your windows or skylights can prevent costly damage and increase your home’s efficiency. Here are some common signs that it may be time for replacement:

  • Drafty or difficult-to-operate windows
  • Moisture between glass panes or skylight glazing
  • Water stains or leaks around skylights
  • Rotted, warped, or visibly damaged frames
  • Increasing energy bills due to poor insulation


If you're experiencing any of these issues in your Glen Ellyn home, our team will provide a detailed inspection and honest recommendations. Replacing windows or skylights is an investment in your comfort, safety, and long-term home value.

several other companies! Highly recommend! A+++++"

There are some key reasons we would recommend Nick and his crew:

they kept appointments and returned phone calls. The crew was professional

and always left the work site clean. They made sure everything was watertight

before leaving in case of bad weather. Worked well with our insurance adjustor

…to get the most value out of our budget without going over. Thanks, Nick!
