Over time, wooden screen doors can droop and begin to rub. Your first step should be to try tightening the hinge screws. If that doesn’t fix the problem, check to see if the joints in the door are loose, causing it to sag out of square. If that’s the case, correct the problem with a door brace (Photos 1 and 2). Purchase a 50-in. long door brace ($7) from a hardware store or home center, and take 20 minutes to complete the repair.
Here are some tips to make the job easier:Before you begin hanging the brace hardware, join the threaded ends of the brace’s two halves by screwing each of them 1/2 in. (but no more) into the metal turnbuckle.
Once the door brace is on and tightened, remove the door support blocks, close the door and check the gaps around it. Adjust the turnbuckle until the door closes smoothly.
Add a turnbuckle to a new door to prevent future sagging.

1. Support the outer edge of the door with wood scraps and screw one end of the brace to the center of the door stile 3 in.
from the bottom. Drill a pilot hole and install only one of the two screws. Then drill pilot holes and screw the top end to the center line of the hinge-side door stile. Install the final screw in the lower brace.
2. Insert a 16d nail into the turnbuckle hole and turn the turnbuckle clockwise to adjust the door until it fits. Take care not to tear the screen.
