Replacing Screens. We are replacing the 8 x 4-ft. screens around our porch ourselves, and itβs pretty easy. My neighbor paid a contractor $1,400 to do the same on her smaller porch. We spent approx. $300 for the screen (upgraded 10-year, small mesh black screen, 400 feet of spline, new screws and a spline tool.
Remove the old spline with a thin blade to start, then peel up and remove. Roll up and dispose of old screen. Now is a good time to use an old toothbrush to brush dirt from the groove where the new screen will go. If the frames are really dirty, wash them off with hot water and let dry.
Place the frame on a sturdy surface, groove side up.
Working from the top, place the roll of screening with an inch margin above the top of the frame.
Unroll a couple feet to align one side to assure screen will be straight.
Use the male end of the spline tool to roll the screen into the spline groove.
Now, press the spline into the spline groove with the female end of the spline tool.
Take your time and GO SLOW on your first one.
You will get the hang of it pretty quickly. Tip: When rolling the new spline onto the screen, keep the tool turned toward the outer edge so if you slip, you wonβt cut the screen.
