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

While we are not a distributor or installer of new Northern Comfort Windows, nor do we handle repairs or sales of specific Northern Comfort Windows parts, we are fully equipped to offer comprehensive installation of a new “replacement unit.” This service comes with complete warranties, making it an ideal solution if your existing windows require the replacement of the interior glass or thermopane due to any kind of failure.

We offer comprehensive year-round services for window replacement/repair services, including sealed unit replacement, thermopane replacement, window crank repair, hardware replacement, and screen replacement, catering to renowned brands such as Northern Comfort windows, particularly when they surpass their warranty period. Whether serving residential or commercial clients, our team consistently delivers projects that epitomize our commitment to superior quality and utmost customer satisfaction. When it comes to expertise in Ottawa’s glass industry, choose Centennial Glass & Window for unparalleled service.

Types of Window Replacement/Repair Services We Provide

New Glass, Thermopane or Sealed Unit Replacement

Broken windows are a common occurrence. We remove the expired, damaged, or failed glass, measure the space precisely, match your new sealed unit exactly, professionally install the unit, seal it tightly, clean it for you, and extend full warranties for the replacement glass and our installation services.

Window Crank Replacement

The window’s functionality relies on the crank mechanism for smooth movement. If it’s malfunctioning, your window could become hard to open or close. Visit our store to browse our universal hardware options, allowing you to find the exact replacement you need. Our knowledgeable customer service teams are available to offer professional advice and assistance. You can send us a photo of the item requiring replacement, and we’ll promptly arrange for our skilled installation teams to handle the task. Ensuring your windows are in optimal working condition is our priority. The importance of quality hardware must be considered when it comes to maintaining the functionality of your windows.

Foggy Window Replacement

We specialize in replacing foggy windows while ensuring optimal insulation between the panes. Attempting to defog a window unit risks releasing the argon gases sealed within. Temporary solutions like drilling holes into the glass are not advisable. When faced with foggy windows, opting for a new replacement unit is the recommended course of action, and defogging is a practice we discourage. Centennial Glass replaces your foggy windows with new sealed units seamlessly integrated into the existing frame, maintaining your window’s aesthetic appeal. Our replacements come with full warranties, extending the lifespan of your windows for many more years to come.

Screen Replacement

Experiencing ripped, torn, or damaged screens? Centennial Glass offers convenient walk-in services at our showroom and cut shop, where we specialize in professionally replacing the most damaged screens. Our knowledgeable staff can guide you through various screen types and screen bar options, ensuring you find the perfect fit for your needs. We recommend bringing your existing screens to the shop for assessment. Alternatively, you can fill out our online screen-builder web form, providing photos, measurements, and details to help us determine the best replacement service for you. Rest assured, we offer onsite services based on your specific replacement requirements. Whether you prefer phone, walk-in, or online inquiries, our dedicated customer service team is ready to assist you every step of the way.
