What you need to do before you start
Replacing a screen door means removing the old frame from the hinges, taking out the damaged mesh, and either patching it or installing a new frame. Most homeowners can do this in an afternoon with basic tools. The hardest part is usually getting the frame out cleanly without damaging the door jamb—the wooden frame around your doorway.
Before you buy anything, measure your doorway opening from the inside. Write down the width and height in inches. Check whether your door swings inward or outward, and which side the hinges are on. Take a photo of the hinge setup with your phone. Bring these measurements and the photo to a hardware store, and a staff member can show you what size frame fits your space.
If only the mesh is torn and the frame is straight and undamaged, you can patch or re-mesh the existing frame instead of replacing the whole door. That costs less and takes 30 minutes. If the frame is bent, cracked, or the door no longer closes tight, replacement is the better choice.
Key Takeaways
- Measure your doorway opening and take a photo of your hinges before shopping, so you buy the correct size and type of door.
- Remove the old door by unscrewing the hinges from the door jamb, not from the door itself, to avoid damaging the frame.
- Install the new frame by screwing the hinges into the jamb at the same height as the old ones, then adjust the door so it closes smoothly without rubbing.
- If only the mesh is torn, you can buy a patch kit or re-mesh the existing frame for under $20 instead of replacing the whole door.
Removing the old screen door
Start by opening the door fully. Look at the hinges—they are the metal brackets that hold the door to the jamb. You will see screws going through the hinge into the wood. Do not remove the screws from the door side. Instead, unscrew the hinges from the jamb (the vertical wood frame around the doorway). This keeps the door balanced and prevents the frame from twisting.
Use a screwdriver that fits the screw head snugly—a loose fit strips the screw and makes it spin without turning. Start with the top hinge. Remove one screw at a time, and have someone hold the door level as you work. Once all the screws are out, lift the door straight up and away from the jamb. Set it down flat on a clean surface so the frame does not bend.
If the door is stuck, do not force it. Check for paint or caulk sealing the edges. Use a utility knife to cut along the seam between the door frame and the jamb, then try again. If hinges are rusted and screws won't turn, spray them with penetrating oil and wait 15 minutes before trying again.
Preparing the jamb for a new door
Look at the jamb where the old hinges were. You will see screw holes and possibly some paint or debris. Use a wire brush or old toothbrush to clean out the holes and remove any loose paint or rust. If the wood is splintered or gouged, sand it lightly with 120-grit sandpaper until it is smooth. Wipe away the dust with a damp cloth and let it dry.
Check that the jamb is straight by holding a level against it vertically. If it leans more than 1/8 inch over the height of the door, the new door may not close properly. Small gaps can be shimmed (filled with thin wood wedges) during installation, but a badly warped jamb may need repair before you hang the new door.
If you are replacing the door in the same location, the old screw holes should line up with the new hinges. If the holes are stripped (the screws spin without gripping), fill them with wooden toothpicks and wood glue, let the glue dry, then break off the toothpicks flush with the surface. The new screws will bite into fresh wood.
Installing the new screen door
Lay the new door frame on a flat surface and check that it is square by measuring diagonally from corner to corner—both measurements should be the same. If they differ by more than 1/4 inch, the frame is twisted and should be returned.
Have a helper hold the new door in the opening while you check the fit. The door should sit evenly in the jamb with a gap of about 1/8 inch on all sides. If the gap is uneven, use shims (thin wood wedges) under the bottom of the frame to level it. Once it is level and plumb (straight up and down), mark the hinge screw holes with a pencil.
Remove the door and drill pilot holes at each mark using a drill bit slightly smaller than your screws. Pilot holes prevent the wood from splitting and help the screws go in straight. Reinstall the door and screw the top hinge in first, using only one screw. Check that the door closes without rubbing, then add the remaining screws. If the door binds (sticks when closing), loosen the screws slightly, adjust the frame, and tighten again.
Adjusting the door so it closes smoothly
Once all hinges are screwed in, open and close the door several times. It should swing freely and close with a soft click when the latch catches. If it rubs on the top or bottom, the frame may need shimming or the hinges may need adjustment.
If the door rubs at the top, loosen the top hinge screws by half a turn and tap a shim under the bottom of the frame with a hammer. Tighten the screws and test again. If it rubs at the bottom, remove the shim or add one under the top hinge instead. Make small adjustments—1/16 inch at a time—because a little goes a long way.
If the door does not close all the way or swings open on its own, the frame may be twisted. Check with a level again. If the frame is level but the door still swings, the hinges may be worn or the latch may need adjustment. Most screen doors have an adjustable closer (a spring mechanism at the top) that you can tighten with a screwdriver to make the door close faster.
Patching a torn mesh instead of replacing the door
If the frame is straight and only the mesh is damaged, a patch kit costs $5 to $15 and takes 30 minutes. Buy a patch kit that matches your mesh color and type (fiberglass or aluminum). The kit includes a small piece of mesh and adhesive strips or a roller tool.
Clean the torn area with a dry cloth. Cut the patch at least 1 inch larger than the tear on all sides. Peel the backing off the adhesive strips and press the patch firmly over the tear, smoothing out air bubbles as you go. If your kit includes a roller, run it over the patch to seal the edges. Let the adhesive cure for 24 hours before using the door.
For larger tears or multiple holes, re-meshing the frame is more durable. Remove the spline (the rubber cord holding the mesh in place) by prying it out with a flathead screwdriver. Lift out the old mesh. Lay new mesh over the frame, cut it 2 inches larger than the frame on all sides, and use a spline roller tool to press the new spline and mesh into the groove. Trim the excess mesh with a utility knife. This takes about an hour and costs $10 to $25 for materials.
When to call a professional
Call a handyperson or door installer if the jamb is cracked, rotted, or badly warped. Water damage or termite damage to the wood frame means the door will not seal properly no matter how well you install it, and the underlying damage needs repair first.
If the hinges are broken or the door frame is bent beyond straightening, replacement is necessary but still a straightforward job. If you are not comfortable working with screws and levels, or if you have mobility issues that make holding the door while installing hinges difficult, a professional can do the job in an hour or two.
Frequently Asked Questions
Can I replace just the mesh without removing the door?
Yes. If the frame is in good shape, you can patch small tears with an adhesive patch kit while the door is still hanging. For larger damage or re-meshing, it is easier to remove the door and lay it flat on a work surface, but not required.
What if the new door is slightly too big for the opening?
Most screen doors come in standard sizes that fit standard openings. If the new door is 1/4 inch too large, you can trim the frame with a circular saw, but this is difficult and risks damaging the hinges. Return the door and order the correct size instead.
Do I need to remove the old door before measuring for a new one?
No. Measure the opening from inside the jamb (the wood frame itself), not including the old door. If you measure with the old door in place, subtract its thickness from your measurement. Taking a photo of the hinges helps the hardware store staff confirm you are buying the right type.
How tight should the hinges be screwed in?
Screw the hinges in snugly, but do not over-tighten. If you strip the screw hole, the hinge will not hold. A good rule is to stop when you feel solid resistance, then give the screwdriver one more quarter turn. If the door sags later, you can tighten the screws a bit more.
What if the door closes but does not latch?
The latch (the small hook at the edge of the door) may not be aligned with the strike plate (the metal piece on the jamb). Loosen the strike plate screws and slide it up or down until the latch catches smoothly. If the latch is bent, the door may need to be returned.
