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. Remember, the right hardware is crucial for the optimal functioning of your windows.

Foggy Window Replacement

We specialize in replacing windows that have become foggy, ensuring that 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 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.
