Centennial Glass provides window repair services for 99% of windows brands out of their warranty period, like North Star Windows. 

We are not a dealer or installer of new North Star Windows windows, nor do we repair or sell specialized parts for North Star Windows. Still, we can provide you with full-service installation of a new “replacement unit” with full warranties for your existing windows if you need the interior glass/thermopane replaced due to failure of some sort.

With years of experience and a deep commitment to quality, we have set the standard for the region’s glass, glazing, and window replacement. We provide year-round window replacement/repair services (sealed unit replacement, thermopane replacement, window crank, window hardware replacement, and screen replacement) for brands like the North Star windows, especially if they are out of their warranty period. Serving residential and commercial clients, our team ensures that every project reflects our dedication to excellence and client satisfaction. (Choose Centennial Glass & Window for unparalleled expertise in Ottawa’s glass industry).

Types of Window Replacement/Repair Services We Provide

New Glass, Thermopane or Sealed Unit Replacement

Broken windows are common. We take out the expired, damaged or failed glass, measure the space, exactly match your new sealed unit to be replaced, professionally install the unit, seal it tight, clean it for you, and extend full warranties for the replacement glass and our installation services.

Window Crank Replacement

The crank helps the window move. If it’s not working, the window might stick. Shop in-store and replace the item you need with our universal hardware options, and get professional advice from our customer service teams; send a photo of the item you need replacing, and or we can schedule this service with our professional installation teams, making sure your windows are in optimal working condition. Hardware is always important to the success of your window functioning properly.

Foggy Window Replacement

We replace foggy windows, ensuring the panes are well-insulated. There’s no way to defog a window unit without letting the argon gases out between the panes. Drilling holes into the glass is a short-term solution. When this happens, you need a new replacement unit, and defogging is a practice we do not recommend. Centennial Glass replaces with a new sealed unit within the existing window frame, to match your existing window aesthetic, with full and complete warranties, extending the existing frames of your windows for many more years.

Screen Replacement

Ripped, torn or damaged screens? Centennial Glass offers walk-in services to our showroom and cut shop, where we can professionally replace most damaged screens and provide customer options on screen types and screen bar options. We recommend you bring your existing screens into the shop, or fill out our screen-builder online webform, and provide photos, measurements, and details so we can help determine what service is best for your screen replacement, but don’t worry, we can offer onsite services depending on the replacement services you need. Our customer service team is ready to answer any questions you may have by phone, walk-in, or online.
