How to Replace Fly Screens in Aluminium Window Screens

Fly screens are an unsung hero in our homes, providing a critical barrier against insects while allowing fresh air to circulate. However, wear and tear or pet damage can leave them less effective. Replacing fly screens, especially in aluminium window screens, is a straightforward task that can refresh your home's functionality and aesthetic.

Step 1: Gathering the Essential Materials

Before diving into the replacement process, ensure you have the necessary materials. You will need:
- Replacement fly mesh, selected based on your specific needs (fibreglass for cost-effectiveness, aluminium for durability, or heavy-duty screens for pet owners).
- A flat-head screwdriver or a spline roller tool.
- A utility knife for trimming the mesh.
- New spline (the rubber cord that holds the screen in the frame).
- A measuring tape.

 Step 2: Removing the Old Screen

Carefully remove the window screen from the frame. Using the screwdriver gently pry out the old spline and remove the damaged mesh. Be mindful not to bend the frame during this process. If the spline isn’t brittle it can be reused.

Step 3: Preparing the New Mesh

Measure your window frame and cut the replacement mesh, leaving a between 50 and 100mm on each side for an easier installation. This extra allowance ensures you have enough material to work with.

Step 4: Installing the New Mesh

Lay the new mesh over the frame. Starting from one corner, use the spline roller to press the spline and the mesh into the groove of the frame. Work your way around the frame, ensuring the mesh is taut and even. This step requires patience and attention to maintain even tension across the mesh. Before you proceed, use the tape measure to measure the diagonal on each corner to ensure the screen is still square. 

Whilst Aluminium mesh and fibreglass mesh tend not to buckle the frames. Because Pet mesh is stronger, be aware on large frames it is possible to pull the frames inwards when tensioning the mesh. The best way to stop this is to brace the frame with a thin piece of timber cut to size. 

Step 5: Trimming Excess Mesh

Once the spline is securely in place, trim the excess mesh with a utility knife. Be careful not to cut into the newly installed screen. Be aware of the angle you place the knife blade at because if the angle is too sharp, you can accidently damage your newly installed mesh.

Step 6: Reinstalling the Screen

 After trimming, reinstall the screen back into the window frame.
