Centennial Glass offers repair services for 99% of window brands, including Fenplast Windows, especially those beyond their warranty period. 

We do not distribute or install new Fenplast Windows, nor do we handle repairs or sales of specific Fenplast Windows parts. But we are well-equipped to offer you a complete installation of a new “replacement unit.” This service comes complete with full warranties, making it an ideal option if your existing windows require the replacement of the interior glass or thermopane due to any kind of failure.

For over 55 years, Centennial Glass has been a revered name in exceptional window installation and replacement services across Ottawa, Ontario. Our extensive experience and unwavering dedication to quality have made us a benchmark in the region for glass, glazing, and window replacement services. We offer a full range of window replacement and repair services throughout the year, including sealed unit replacement, thermopane replacement, window crank and hardware replacement, and screen replacement, with a particular focus on Fenplast windows, especially those past their warranty period. Catering to both residential and commercial clients, our skilled team ensures every project exemplifies our commitment to excellence and customer satisfaction.

Types of Window Replacement/Repair Services We Provide

New Glass, Thermopane or Sealed Unit Replacement

Damaged windows are a common issue. Our process involves removing the old, damaged, or malfunctioning glass, then accurately measuring the space to ensure a perfect fit for your new sealed unit. We expertly install the new unit, ensure it is securely sealed, and clean it thoroughly. Plus, we offer comprehensive warranties for both the replacement glass and our installation services.

Window Crank Replacement

The crank is essential for window operation. Should it become faulty, the window may not open or close smoothly. You can visit our store to find and replace the necessary parts from our wide range of universal hardware. Our customer service teams are on hand to provide expert guidance; you can also send a photo of the hardware you need to replace for more specific advice. If needed, we can arrange for our skilled installation teams to provide the service, ensuring your windows function optimally. Remember, the correct hardware is key to ensuring your windows work properly.

Foggy Window Replacement

We specialize in replacing windows that have become foggy, ensuring the new panes are properly insulated. Defogging a window unit, which often requires releasing the argon gas trapped between panes, isn’t a lasting solution, and drilling holes offers only temporary relief. Therefore, we recommend against defogging. Instead, Centennial Glass installs new sealed units within your existing window frames, maintaining the look of your current windows. These replacements come with full and comprehensive warranties, prolonging the life of your window frames for many additional years.

Screen Replacement

If your screens are ripped, torn, or have suffered any damage, Centennial Glass is here to assist with our convenient walk-in services. At our showroom and cutting facility, we can expertly replace most types of damaged screens and offer a variety of choices in screen materials and frame styles. For the best results, we suggest bringing your damaged screens to our shop. You can use our online screen-builder tool to provide photos, measurements, and specific details, allowing us to better understand your needs and recommend the ideal screen replacement service. We also offer onsite services tailored to the specific screen replacement needs you have. Our customer service team is readily available to address any queries you might have, whether you contact us by phone, in person, or online.

The company boasts a vast distribution network encompassing over 80 independent, specialized, or owned dealers. Fenplast distinguishes itself through the complete integration of its manufacturing processes, setting it apart from its competitors.
