Centennial Glass offers repair services for nearly all window brands, including Pella Windows, especially those beyond their warranty period. 

While we are not a distributor or installer of new Pella Windows, nor do we handle repairs or sales of specific Pella Windows parts, 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 Pella 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 frequent occurrence. Our process involves removing the old, damaged, or malfunctioning glass, precisely measuring the space, and ensuring an exact match for your new sealed unit replacement. We then expertly install the unit, securely seal it, and thoroughly clean it. Additionally, we provide comprehensive warranties for both the replacement glass and our installation services.

Window Crank Replacement

The functionality of a window often hinges on its crank mechanism. A malfunctioning crank can lead to a window that sticks or fails to open correctly. To address this, you can visit our store to find a variety of universal hardware options suitable for replacement. Our customer service teams are ready to offer professional advice; you can also send us a photo of the hardware you need to replace. Alternatively, we can arrange for our professional installation teams to handle the service, ensuring your windows operate smoothly.

Foggy Window Replacement

We specialize in replacing foggy windows, making sure the new panes provide proper insulation. Unfortunately, defogging a window unit is not a viable long-term solution, as it involves releasing the argon gas between the panes, and drilling holes in the glass only offers temporary relief. As such, we advise against defogging practices. Instead, Centennial Glass provides new, sealed units that fit within your existing window frames, perfectly aligning with the aesthetics of your current windows. With our replacements, we offer comprehensive warranties, ensuring that your window frames are set to last for many more 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 optimal service, we suggest bringing your damaged screens to our shop. Alternatively, 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. If required, 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.
