Centennial Glass offers repair solutions for almost all window brands beyond their warranty period, including brands like Clera Windows. 

While we do not deal in or install new Clera Windows, nor do we offer repairs or sales of specific parts for Clera Windows products, we can provide complete installation service for a new “replacement unit.” This service includes full warranties, making it an ideal option if your existing windows require the replacement of interior glass or thermopane due to any failure.

For over 55 years, Centennial Glass has remained a leader in exceptional window installation and replacement services in Ottawa, Ontario. Our extensive experience and steadfast dedication to quality have established us as the benchmark for glass, glazing, and window replacement in the region. We offer a comprehensive suite 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 focus on brands like Clera windows, especially post-warranty. Serving both residential and commercial clients, our team is committed to ensuring that every project reflects our high standards of excellence and customer satisfaction.

Types of Window Replacement/Repair Services We Provide

New Glass, Thermopane or Sealed Unit Replacement

Broken windows are a frequent 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, and offer comprehensive warranties for both the replacement glass and our installation services.

Window Crank Replacement

The crank mechanism is essential for window operation. If it malfunctions, the window may become stuck. You can visit our store to find and replace the necessary item from our range of universal hardware options. Our customer service teams are on hand to provide expert advice. You can also send us a photo of the item you need replaced. Alternatively, we can arrange for our professional installation teams to perform the service, ensuring your windows function optimally. Remember, the right hardware is key to ensuring your windows work properly.

Foggy Window Replacement

We specialize in replacing windows that have become foggy, making sure the new panes provide proper insulation. It’s important to note that defogging a window unit, which often involves releasing the argon gas between the panes, is not a viable long-term solution, and drilling holes in the glass offers only temporary relief. Therefore, we do not advise defogging. Instead, Centennial Glass offers the installation of new sealed units within your existing window frames. This not only maintains the aesthetic of your current windows but also comes with full warranties, enhancing the longevity of your window frames for years to come.

Screen Replacement 

If you’re dealing with screens that are ripped, torn, or otherwise damaged, Centennial Glass is here to help. Our showroom and cut shop are open for walk-in services, where our professionals can replace most types of damaged screens. We provide a range of options for screen types and screen bar styles. For the best service, we suggest bringing your current screens to our shop. Alternatively, you can use our online screen-builder webform to submit photos, measurements, and details. This helps us determine the most suitable screen replacement service for your needs. If necessary, we also provide onsite services tailored to your specific replacement requirements. Our customer service team is always ready to assist you, whether you call, visit us in person, or reach out online.
