How to Repair a Screen Door Closer

Most screen door closer problems stem from loose screws, worn springs, or misaligned brackets that can be fixed with basic adjustments and occasional part replacement.

1. Tighten Every Screw First. Start with the simplest fix. Use a screwdriver to check every screw on both the door bracket and frame bracket. Loose screws are the most common cause of door closer problems. Tighten any loose screws, but don't overtighten as this can strip the holes in aluminum door frames.
2. Find the Broken Spring. Look at the spring inside the closer tube. If it's stretched out, broken, or has lost tension, you'll need to replace it. Most closers have a removable cap on one end where you can access the spring. Remove the cap carefully as springs can snap back with force.
3. Stop the Door Slamming. Locate the tension adjustment screw, usually on the end of the closer tube. Turn clockwise to increase closing force, counterclockwise to decrease it. Make small quarter-turn adjustments and test the door each time. The door should close firmly but not slam.
4. Straighten Bent Brackets. Hold a straight edge against both brackets to ensure they're aligned. Misaligned brackets cause the closer to bind and wear out quickly. If brackets are bent, try to straighten them gently with pliers. Severely bent brackets need replacement.
5. Oil the Moving Parts. Apply a few drops of 3-in-1 oil to the pivot points and spring mechanism. Work the door back and forth several times to distribute the oil. Avoid heavy greases which attract dirt and can gum up the mechanism in hot weather.
6. Swap Out Worn Parts. If adjustments don't solve the problem, replace worn parts. Springs, rubber bumpers, and pivot pins are common wear items. Take the old part to the hardware store to ensure you get the right replacement. Most closer manufacturers use standard-sized components.
