Steps

1
Remove the screen frame from the window and lay it flat on a work surface with the grooves facing up.
Frame Channel Work Surface Screen Mesh Lay flat Place frame on a flat surface with the spline channel facing upward.
2
Use a flat-head screwdriver to pry the existing rubber spline out of the channel around the perimeter of the frame, then lift out and discard the torn screen material.
Tip: Bring the old spline to the store to ensure the replacement you buy is the proper size.

3
Lay the new screen mesh over the frame. Cut the material to size, leaving an overlap of 1 to 2 inches of screening material on all four sides.
Tip: Place the screen material curved side down when unrolling for easier handling.

4
Position the mesh and use masking tape or clamps to secure it to the top and bottom of the frame to keep the material taut.
Tip: Ensure the mesh overlaps the metal on all four sides.

5
Use the convex (pointy) wheel of the spline rolling tool to push the screen material into the frame channel, working from one corner to the next. Then, use the concave (grooved) side of the tool to press the plastic spline into the channel to lock the screen in place.
Tip: Avoid pulling too tightly as you near completion to prevent bending the frame.

6
Trim the excess screening material with a utility knife, cutting on the outside of the new spline and angling the blade away from the spline to avoid cutting it.

7
Inspect the corners and edges to ensure the mesh is taut and secure, then reinstall the finished screen frame back into the window.

Pro Tips

  • Fiberglass screen is flexible and easy to install, whereas aluminum is sturdier but has a 'memory' and is harder to reposition if a mistake is made.
  • Pet-resistant screens made of vinyl coated polyester are recommended for households with cats or dogs.
  • Store screens in a dry place like an attic or basement during winter to prevent damage from snow and ice.

When to Call a Professional

If the window frame is damaged or requires custom-sized screens, consult a professional window repair service.
