Centennial Glass offers window repair solutions for 99% of windows brands that have surpassed their warranty period, such as Dalmen Windows. 

We do not function as a distributor or installer for new Dalmen Windows, and we do not handle the repair or sale of specialized Dalmen Windows components. However, should you require the replacement of your interior glass/thermopane due to any kind of failure, we are fully equipped to provide you with comprehensive installation services for a new “replacement unit,” complete with warranties for your existing windows.

With a wealth of experience and an unwavering commitment to excellence, we have set the benchmark for glass, glazing, and window replacement in the region. Our comprehensive range of year-round window replacement and repair services includes sealed unit replacement, thermopane replacement, window crank repair, window hardware replacement, and screen replacement, tailored to brands like Dalmen windows, particularly when they are no longer covered by their warranties. Whether serving residential or commercial clients, our dedicated team ensures that every project mirrors our relentless pursuit of perfection and customer satisfaction. When you need unparalleled expertise in Ottawa’s glass industry, choose Centennial Glass & Window.

Types of Window Replacement/Repair Services We Provide

New Glass, Thermopane or Sealed Unit Replacement

Window damage is a frequent occurrence. We expertly remove the broken or worn-out glass, take precise measurements of the opening, ensure an exact match for your new sealed unit, professionally install it with a secure seal, perform a thorough cleaning, and provide comprehensive warranties for both the replacement glass and our installation services.

Window Crank Replacement

The window crank plays a crucial role in facilitating window movement, and if it malfunctions, your window may become difficult to open or close. You can visit our store to explore a range of universal hardware options, and our knowledgeable customer service teams will provide expert guidance to help you select the right replacement. You can send a photo of the item you need to replace, and we can arrange for this service to be performed by our skilled installation teams, ensuring that your windows operate flawlessly. The quality of your hardware is paramount to the proper functioning of your windows.

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

We specialize in the replacement of foggy windows, ensuring that the new panes are properly insulated. Attempting to defog a window unit without releasing the argon gases between the panes is not a viable solution, and drilling holes into the glass is only a temporary fix. In such cases, what you truly require is a brand-new replacement unit, and we strongly advise against attempting to defog the window. At Centennial Glass, we seamlessly replace your existing window unit with a new sealed one that matches the aesthetics of your current window frame. We back our service with comprehensive warranties, effectively extending the lifespan of your existing window frames for many more years to come.
