Easy Tips for Removing & Replacing Window Spline

Fiberglass mesh screens are commonly used in windows and doors to keep insects out while allowing air to flow freely. However, over time, these screens may require repairs due to tears or damage. Repairing fiberglass mesh screens may seem daunting, but with the right techniques, it can be a straightforward task. In this blog post, we'll explore expert tips for repairing fiberglass mesh screens, as shared by a professional.

  • Assessing the Damage:

When repairing a fiberglass mesh screen, the first step is to assess the extent of the damage. There are various ways to approach this task. In some cases, the screen may pop right up with a gentle push, allowing easy access to the damaged area. However, in other instances, it may be necessary to cut the mesh to access the damaged section. This step requires careful consideration to avoid further damage to the screen.

  • Handling Different Materials:

It's essential to consider the material of the screen mesh when performing repairs. Fiberglass mesh screens are relatively easy to work with compared to aluminum screens. Aluminum screens pose additional challenges due to their sturdier nature, requiring extra caution during the repair process. Regardless of the material, safety precautions must be taken to prevent injuries, such as cuts from sharp edges.

  • Replacing the Spline:

The spline, a flexible cord that holds the screen in place within the frame, plays a crucial role in screen repairs. While it is possible to reuse the spline in some cases, it often becomes stretched out after installation. As a result, it's generally recommended to use the spline and spline tool provided in our screen repair kits. This ensures a secure fit and minimizes the risk of the screen coming loose over time.


Repairing fiberglass mesh screens requires attention to detail and careful handling to achieve optimal results. By assessing the damage, handling different materials appropriately, and replacing the spline as needed, homeowners can effectively restore their screens to full functionality without the need for professional contractors. 

Whether it's a minor tear or significant damage, tackling screen repairs promptly can help prolong the lifespan of these essential household fixtures. For more information on DIY screen repair or help ordering replacement parts, Contact Us Today! The WHD Team looks forward to hearing from you.
