Screen doors are great for letting fresh air in while keeping insects out, but they can develop issues over time. This guide covers common screen door problems and provides step-by-step instructions for fixing them. Whether you have a torn screen, a sticky sliding mechanism, or broken hardware, we’ll help you get your screen door working properly again.
What Tools and Materials Will You Need?
Have everything on hand to make the repair process smooth. To fix most screen door issues, you’ll need the following tools:
- Flathead screwdriver
- Phillips head screwdriver
- Utility knife
- Measuring tape
- Splining tool
- Spring clamps
- Pliers
Depending on the specific repair, you may also need some (or all) of these materials:
- New screen material (fiberglass or aluminum)
- Spline (the rubber cord that holds the screen in place)
- Replacement rollers
- New handles or latches
- Lubricant for tracks and rollers
Pro Tip: Tom Silva, This Old House general contractor, recommends fiberglass screening over aluminum for groove-and-spline frames: “If you mess up, just take it out and do it again. Metal stays kinked.”
How To Prepare for Screen Door Repair
Start by removing the screen door from its frame. For sliding doors, lift the door and tilt it out of the bottom track. For swinging doors, remove the hinge pins. Always handle your door carefully to avoid injury or damage.
Once you remove the door, set up a stable work surface. This could be a workbench, a sawhorse covered with plywood, or even your picnic table. Check that you have adequate lighting and space to maneuver around the door.
For sliding screen doors: Before lifting the door out, look for roller adjustment screws at the bottom of the frame — they’re sometimes hidden behind small plugs or located in the edges of the door. Insert a flathead screwdriver into each hole and turn the screw all the way counterclockwise to retract the rollers and lower the door. This makes removal much easier. As noted in This Old House Magazine, don’t leave the door unattended once the head stop is removed; without it, the panel can fall.
How Do You Repair a Torn Screen?
One of the most common issues with screen doors is damage to the screen. Pets scratching at the door, accidental impacts, and general wear and tear can all rip the screen. A torn screen looks bad and lets insects in, so fixing the issue quickly is important. Here’s how to replace the damaged screen with a new one.
This Old House general contractor Tom Silva knows firsthand how quickly screen damage can happen. One balmy evening, a raccoon clinging to a window screen in his family room ripped four gaping holes in the wire mesh. Rather than shutting the window and dealing with it later, Tom patched it in minutes. “I didn’t want mosquitoes feasting on us all night,” he says.
Measuring and Cutting New Screen Material
Measure the width and length of your door frame, adding an extra 2 inches on all sides for proper installation. Cut your new screen material to these dimensions. Remember, you can choose from materials like fiberglass or aluminum based on your needs and preferences. No matter the material, take your time measuring and cutting to ensure a better fit and more efficient installation.
Removing the Old Screen
To remove the old screen, first remove the spline. Use a flathead screwdriver to pry out a bit of the spline, then pull the rest out. Once you remove the spline, lift and discard the old screen. We recommend keeping a small sample of the spline material to match to your replacement.
Installing the New Screen
Lay the new screen material over the door frame, ensuring it’s centered and pulled taut. Use spring clamps to secure it temporarily. Starting at one corner, use a spline tool’s concave wheel to press new spline material into the groove around the frame’s perimeter. Work slowly and carefully, keeping the screen tight as you go.
When you reach the opposite corner, use a utility knife to trim the excess spline. Cut away from the screen toward the outer edge of the screen panel. Repeat the process on each side, smoothing out wrinkles as you go.
Pro Tip: When rolling the spline into the groove, always go in one direction — never back the wheel up. As This Old House general contractor Tom Silva explains on Ask This Old House, “As the spline goes into the groove, it actually pulls the screen taut.” At corners, use a flat-blade screwdriver to force the spline tight, since the roller won’t fit into the tight turn.
How Can You Fix Misaligned Tracks?
Sliding screen doors can become misaligned in their tracks, making them hard to open and close smoothly. Debris in the tracks, worn rollers, or the door being knocked out of position can cause this issue. If left unaddressed, misaligned tracks lead to more wear and tear.
Pro Tip: Joe Giagnorio, service manager for Ring’s End Lumber in Darien, Connecticut, who repairs about 80 sliders a year, points to debris as the primary culprit: “Mud, food, and hair get ground onto the track. All that dirt clogs the rollers underneath the door.”
Cleaning the Tracks
Remove any debris, dirt, or buildup that could stop the door’s movement. A vacuum cleaner with a narrow attachment is helpful for this task. Then, wipe with a damp cloth. Clean tracks reduce friction and allow the door to slide more easily.
Adjusting the Rollers
Many sliding screen doors have adjustable rollers at the bottom. Look for small screws near the bottom corners of the door. Turning these screws clockwise usually raises the door, while counterclockwise lowers it. Keep adjusting until the door slides smoothly and aligns with the track.
Lubricating Moving Parts
Apply a silicone-based lubricant to the tracks and rollers to prevent more alignment issues. Avoid using oil-based lubricants as they can attract dirt and grime.
How To Replace Broken Handles and Latches
Screen door hardware, such as handles and latches, can break or loosen with use. This can make the door difficult to use and prevent it from sealing. Here’s how to remove old hardware and install new parts.
Removing Old Hardware
Start by unscrewing and removing the old handle or latch. Keep track of all screws and small parts, as you may reuse them with the new hardware.
Installing New Handles
If you’re installing a new handle, position it in the same location as the old one. Use the screws provided with the new handle or the original screws if they fit. Make sure the handle is securely fastened and moves smoothly.
Attaching New Latches
To install new latches, first align the door and frame components. Test the alignment and check the door’s function before fully tightening the screws.
When To Call a Professional
While many screen door repairs can be do-it-yourself (DIY) projects, some issues call for professional help. Recognizing when to call in an expert can save time and prevent further damage. Here are some scenarios when we recommend calling the pros:
- The door frame is warped or damaged beyond simple repairs
- You’re uncomfortable working with tools or making structural adjustments
- The door is a custom size or made of unusual materials
- You’ve attempted repairs, and the problem persists
