How to Rescreen a Retractable Screen: Step-by-Step Mesh Replacement
To rescreen a roll-up retractable screen, you let the spring unwind safely, take the roller out of the housing, detach the old mesh from the roller and handle bar, attach new mesh perfectly square, then reinstall and retension the spring. Budget about 2 hours for a single door the first time. This page walks through each step and flags the points where most DIY rescreens go wrong.
Key takeaways
- This applies to spring roll-up door and window screens. Pleated screens and zip-track screens are usually replaced as a panel, not rescreened.
- Release spring tension before opening the housing. A wound spring can spin the roller hard enough to hurt fingers.
- Count the turns of spring preload as you release them; you will put the same number back.
- Squareness is everything: mesh attached even 1/8 in (3 mm) out of square on the roller will walk sideways and bunch on a tall screen.
- Use the same mesh thickness as the original unless the manufacturer approves a substitute.
Before you start: is this screen rescreenable?
Most spring roll-up door and window screens can be rescreened if the mesh is attached to the roller with spline or tape and to the handle bar with spline or a clamp. Some cannot be economically:
- Pleated screens use a factory-pleated polyester mesh strung on cords. Replacement is normally a factory pleat kit or a new panel.
- Zip-track screens have zipper strips welded to the mesh edges. You order a new welded panel to exact size; see zip-track, keder and zipper edges.
- Sealed cassettes on some budget units are riveted shut and the spring is not adjustable. Replacement mesh often costs more in time than a new unit.
- Motorized patio screens follow a different procedure because the roller holds a tubular motor and the mesh is usually a welded fabric panel.
If the screen also has a weak spring, bent tracks or a broken latch, fix those in the same session. Diagnosis for those faults is in retractable screen repair.
Tools and materials
- Replacement mesh, same type and thickness as original, at least 6 in (150 mm) longer and 2 in (50 mm) wider than the visible screen (see screen mesh types)
- New spline in the right size for the roller and bar grooves (see spline size guide), or the manufacturer's double-sided tape if the roller is taped
- Spline roller, utility knife with fresh blades, straightedge
- Screwdrivers, a small pick, needle-nose pliers, possibly a hex key set
- Locking pliers or a spring winder tool if the housing has a removable end with a spring stub
- Painter's tape, a fine marker, a framing square or a long level
- Two clean sawhorses and a long, flat work surface (a door on sawhorses works)
- Phone camera for photos of every part before you take it apart
Spring safety
How the spring stores energy, and how preload relates to screen height, is explained in retractable screen spring tension.
Step-by-step: rescreening a spring roll-up screen
- Photograph and measure. With the screen fully closed (mesh out), photograph the housing ends, the handle bar ends and any adjustment screws. Measure the visible mesh width and the full extended height. Note which way the mesh comes off the roller: over the front or from the back.
- Retract fully and release tension. Let the screen roll up under control. On most units, the tension adjustment is a slotted or hex stub on one end cap. Hold it firmly, release the lock (a set screw, a detent or a pin), and let it unwind in controlled half-turns. Count every full turn and write the number down. When the stub stops pulling against you, the spring is at rest.
- Remove the housing from the frame. Unclip or unscrew the housing from its mounting brackets. Slide the handle bar out of the guide tracks if needed. Lay everything on the work surface.
- Open the housing and remove the roller. Take off the end caps and slide the roller out. Keep left and right parts separate and labeled; idler ends and spring ends look similar and are not interchangeable.
- Strip the old mesh. Unroll the mesh fully. Pull the spline out of the roller groove with a pick, or peel the mesh off the tape. Remove the mesh from the handle bar the same way. Clean the grooves; old tape residue comes off with a plastic scraper and a little citrus solvent. Keep the old mesh as a template.
- Cut the new mesh to size. Lay the old mesh over the new mesh and cut the new piece about 1 in (25 mm) wider and 3 in (75 mm) longer than the old one. Leave the factory edges on the long sides if the mesh roll has them; they are straighter than a cut edge. You will trim the final width after attaching.
- Mark a square reference line. Draw a straight line along the roller length (use the groove itself, or a line marked with a straightedge on tape). On the mesh, mark a line across the top that is exactly perpendicular to the long edges using a framing square. This is the step that decides whether the screen tracks straight.
- Attach the mesh to the roller. Align the mesh line with the roller groove or tape edge. For spline, roll it in starting at the center and working out to each end, holding the mesh slightly taut sideways. For tape, peel a short length of backing, set the center, then work out. Check the mesh edges are parallel to the roller ends by measuring both sides.
- Roll the mesh onto the roller. Roll the mesh evenly onto the tube by hand, watching both edges. If one edge starts to step out more than about 1/16 in (1.5 mm) per wrap, the attachment is out of square. Unroll, detach and redo step 8 now; it will only get worse at full height.
- Attach the handle bar. Unroll to full screen height plus about 2 in (50 mm). Square the handle bar to the mesh edges with the framing square, then spline or clamp the mesh into it. The mesh should sit flat across the bar with no diagonal wrinkles.
- Trim the width. Trim the mesh edges to the original width with a sharp knife and straightedge. On screens with brush or pile-lined tracks, the mesh usually needs to reach well into the tracks; match the old mesh width exactly rather than guessing.
- Reassemble the housing. Roll the mesh back up, slide the roller into the housing, refit the end caps in their original positions, and remount the housing on the frame. Feed the handle bar into the tracks.
- Retension the spring. With the screen retracted, wind the spring the same number of turns you counted in step 2 and lock it. Pull the screen closed and let it return. It should retract fully and smoothly, without slamming. Add or remove one turn at a time to fine-tune.
- Test and adjust. Cycle the screen ten times. Watch for the mesh rubbing one side of the housing, wrinkles running diagonally, or the bar not seating in its catch. A sideways drift means a squareness problem at the roller; a bar that does not latch is usually a track or latch alignment issue.
Common mistakes and how to avoid them
| Symptom after rescreen | Likely cause | Fix |
|---|---|---|
| Mesh walks to one side when rolling | Mesh attached out of square on the roller | Reattach, using a squared reference line |
| Screen will not fully retract | Thicker mesh than original, roll too large; or too little preload | Use original mesh thickness; add one spring turn at a time |
| Bar slams into housing | Too much preload, or the speed brake was not reengaged | Remove one turn; check the brake end is seated |
| Diagonal wrinkles | Handle bar not square to mesh | Re-spline the bar using a framing square |
| Mesh pulls out of the bar | Spline too small, or old spline reused | New spline, one size larger |
| Mesh frays at edges after a few weeks | Edges too wide and rubbing end caps, or rough track lips | Trim width; check tracks and brush seals |
When to replace instead of rescreen
Rescreening makes sense when the housing, spring, tracks and bar are sound. If the spring is weak, the housing is cracked, or the tracks are bent, a new unit often costs less than parts and time combined. Typical new-unit costs are in our retractable screen cost guide. If the mesh keeps jumping out of the tracks after a rescreen, the problem is usually the track or retention, covered in screen off track.
Frequently asked questions
Can I rescreen a retractable screen without removing it from the door frame?
Rarely. You need the roller out of the housing and the mesh laid flat to attach it square. Trying to do it in place almost always produces a crooked screen that walks to one side.
How many turns of spring tension does a retractable screen door need?
It depends on the model, height and mesh weight. Many door screens run somewhere around 8-15 turns of preload, but the only reliable number is the one you counted when releasing it. Without that count, start low and add one turn at a time until it retracts fully.
Can I use regular window screen from the hardware store?
Usually yes, if it matches the original type and thickness, typically fiberglass in 18x14 or 18x16. Avoid aluminum, which creases on the roller, and check clearance before using thicker pet or solar mesh.
What if my roller uses tape instead of spline?
Use the manufacturer's tape or a high-bond acrylic double-sided tape rated for outdoor use. Clean the tube with isopropyl alcohol first, and press the mesh down firmly along its full length.
Why does my new screen bounce back halfway when I let go?
That is usually too much spring preload or a disengaged speed governor. Remove one turn of tension and confirm the brake end is seated correctly in the housing.
How much does professional rescreening cost?
Prices vary by region and product, but it is usually a fraction of a new unit when parts are available. Ask whether the price includes a new spring and spline, which is often worth doing at the same visit.
