How to Fix a Screen Door

(From a handyman who’s fixed hundreds of them)

Screen doors take a lot of abuse from kids, pets, and weather. The good news: most screen door problems are easy to fix with basic tools and a little patience.

Pro Tip: Take a few clear photos of your door (hinges, rollers, latch) before you take anything apart. Those photos will help you put everything back together the right way.

Common Problems This Guide Covers

  • Screen is torn or has holes
  • Door will not slide or swing smoothly
  • Door will not stay closed or latch right
  • Door is sagging, crooked, or scraping the frame
  • Handle is loose or broken

You can skip to the part you need, or read the whole guide if you want to give the door a full tune-up.

Tools You May Need

  • Phillips screwdriver
  • Flathead screwdriver
  • Utility knife (sharp blade)
  • Tape measure
  • Rubber mallet (or regular hammer with a cloth over it)
  • Needle-nose pliers
  • Screen rolling tool (spline roller)
  • Replacement screen (fiberglass or aluminum)
  • Screen spline (the rubber cord that holds the screen in)
  • WD-40 or silicone spray
  • Level (small one is fine)
  • Wood shims or cardboard strips

You might not need every tool for every repair, but this list covers most screen door jobs.

Part 1: Fixing a Torn or Loose Screen

Step 1: Remove the Screen Door (If Needed)

  1. Open the door and look at how it’s held in place (track, hinges, or rollers).
  2. For sliding doors, lift the door straight up into the top track and pull the bottom out toward you.
  3. For hinged doors, remove the hinge pins or unscrew the hinges, then gently pull the door away from the frame and lay it flat on sawhorses or a table.

Step 2: Remove the Old Screen and Spline

  1. Find the spline (the rubber cord around the edge of the screen).
  2. Use a flathead screwdriver to pry up one end of the spline, then pull it out slowly with your fingers or pliers.
  3. Lift off and throw away the old screen, and clean the groove (spline channel) with a brush or dry rag.

Step 3: Cut and Position the New Screen

  1. Roll out the new screen over the door frame, with a few inches extra on all sides.
  2. Cut the screen with a utility knife, leaving at least 1–2 inches of extra screen beyond the frame.
  3. Center the screen so there is extra mesh evenly on all sides, and hold it in place with a few pieces of painter’s tape or light clamps.

Step 4: Install the New Spline

  1. Start at one corner and press the spline into the groove by hand, trapping the screen.
  2. Use the convex side of the spline roller to gently roll the spline into the groove, working one side at a time.
  3. Keep the screen snug but not too tight as you go, pulling it gently with your hand to avoid wrinkles or bulges.

Pro Tip: Always roll the spline on the opposite sides first (top and bottom, then left and right). This helps keep the screen square and tight.

Step 5: Trim the Extra Screen

  1. Press the spline firmly all the way around to be sure it is seated.
  2. Use a sharp utility knife to cut off the extra screen along the outside edge of the spline, keeping the blade flat against the frame.
  3. Check the screen for any loose areas or waves; if needed, pull out a short section of spline and re-roll it until the screen looks smooth.

Part 2: Fixing a Screen Door That Won’t Slide

(This is for sliding screen doors on patio doors.)

Step 1: Inspect the Rollers

  1. Look at the top and bottom edges of the door and find the rollers (usually near each corner).
  2. Check for broken, cracked, or missing rollers and spin them with your finger to see if they turn freely.
  3. If they are damaged, plan to replace them with the same style and size (take one to the store as a sample).

Step 2: Adjust the Rollers

  1. Find the adjustment screws near each roller (often on the side or bottom edge of the door).
  2. Use a screwdriver to turn the screw: turning one way raises the door, and the other lowers it (there is usually a small arrow or symbol).
  3. Re-hang the door in the track, then slide it back and forth; adjust each roller until the door slides smoothly and sits level.

Step 3: Clean and Lubricate the Track

  1. Remove the door if needed to get better access to the track.
  2. Vacuum the track and wipe it clean with a damp cloth to remove dirt and grit.
  3. Spray a light coat of silicone spray (better than grease because it does not attract dust) and wipe off the extra with a rag.

Part 3: Fixing a Screen Door That Won’t Close or Latch

Step 1: Check the Alignment

  1. Close the door slowly and watch the gap around the edges of the door.
  2. Look for rubbing, scraping, or uneven gaps, especially near the latch side and bottom.
  3. If the door is high on one side and low on the other, adjust the rollers (sliding door) or hinges (swinging door).

Step 2: Adjust the Latch

  1. Look at the latch on the door and the strike plate on the frame.
  2. If the latch does not catch, loosen the screws on the strike plate and move it slightly up, down, in, or out.
  3. Tighten the screws and test the door; repeat until the latch catches firmly without slamming the door.

Step 3: Tighten or Shim Loose Hinges (Swinging Screen Doors)

  1. If the door sags, tighten all the hinge screws on both the door and the frame.
  2. If screws just spin and do not tighten, remove them and fill the holes with wood toothpicks and wood glue, then reinstall the screws.
  3. If the whole door leans, add a thin shim (wood shim or cardboard) behind the hinge plate on the frame, then tighten the screws to lift or shift the door slightly.

Part 4: Fixing a Loose or Broken Handle

Step 1: Tighten the Handle

  1. Look for screws on the inside part of the handle.
  2. Use a screwdriver to tighten the screws while holding the outside handle steady.
  3. Test the handle to see if it feels solid and does not wiggle.

Step 2: Replace the Handle (If Needed)

  1. Remove the old handle by unscrewing all the screws and pulling both halves apart.
  2. Take the old handle set to the store or match the brand and model number for a replacement.
  3. Install the new handle by lining up the holes, inserting the screws, and tightening them evenly until the handle feels firm.

Part 5: Fixing Gaps and Bugs Sneaking In

Step 1: Check Weatherstripping and Corners

  1. Inspect the edges of the door for worn or missing weatherstripping or brush seals.
  2. If they are flat, cracked, or missing, pull them out and cut new pieces to the same length.
  3. Press or slide the new stripping into place according to the door design.

Step 2: Fix Bottom Gap

  1. If you see light under the door, measure the gap with a tape measure.
  2. Install an adjustable sweep or replace the worn bottom seal to match that gap.
  3. Close the door and test; adjust the sweep so it touches the threshold but does not drag hard.

Safety Tips

  • Wear safety glasses when cutting screen or using tools.
  • Cut away from your body when using a utility knife.
  • Keep screws and small parts in a small cup so you don’t lose them.

Final Check

  1. Open and close the door several times to make sure it moves smoothly.
  2. Check the latch to see that it catches every time without forcing it.
  3. Look over the screen for tightness, no wrinkles, and no gaps where bugs can get in.

If you can handle basic tools, you can fix almost any screen door problem in under an hour. Take your time, follow each step, and your screen door will look and work like new.
