Steps

1
Remove the screen door from its frame. For sliding doors, lift the door up into the track and pull the bottom toward you to remove it. If the door is stuck, loosen the adjustment screws near the rollers to create more clearance.

2
Lay the door flat on a protected surface with the spline side facing up. Use a flat-head screwdriver to pry up one end of the old rubber spline, then pull the spline completely out of the groove. The old mesh should now fall away.

3
Clean the frame's groove using a damp rag to remove dirt and grime. If a door handle covers part of the spline channel, use a screwdriver to remove the handle temporarily so the new spline can be installed without obstruction.
4
Unroll the new screen mesh over the frame, ensuring it overlaps the edges by at least one to two inches on all sides. Use small pieces of duct tape to hold the fabric steady and taut against the frame.
Tip: Ensure the grain of the mesh runs parallel to the door frame for a uniform look.

5
Starting at one corner, press the new spline into the groove using the concave wheel of the rolling tool. Work your way around the perimeter using short, choppy strokes to ensure the mesh stays tight and doesn't ripple.

6
Check for ripples or sags in the mesh. If any occur, pull the spline back out, reseat the fabric to increase tension, and re-roll the spline into place. Run the rolling tool over the entire perimeter one last time to ensure the spline is fully seated.

7
Trim the excess screen material. Rest the utility knife blade on the spline in the corner and make a clean cut along the edge of the frame, pulling the excess fabric away as you cut to maintain a straight line.

8
Reinstall the door into the frame. For sliding doors, lift the top into the track first and then drop the bottom rollers into place. Test the door's movement and adjust the roller screws if the door does not slide smoothly.

Pro Tips

  • If you have pets that scratch, choose a vinyl-coated polyester 'pet-proof' mesh instead of standard fiberglass.
  • When choosing spline, ensure the thickness matches your frame groove; if using a thicker mesh, use a slightly thinner spline to make it fit.

When to Call a Professional

Call a professional if the door frame is severely bent, warped, or structurally damaged, as this may require a full door replacement rather than a simple rescreen.
