How to Install a Retractable Screen Door, Step by Step
To install a retractable screen door, you confirm the opening is square and has enough flat jamb, cut the top track and any sill guide to length, fasten the screen housing plumb on one jamb, fit the latch side rail or catch on the other, then adjust spring tension and the latch so the screen glides and closes softly. A competent DIYer can fit a single-door kit in about 1-2 hours. This guide follows the order professional installers use and points out the adjustments that make the difference between a screen that glides and one that snags.
Key takeaways
- Plumb the housing before anything else; an out-of-plumb housing is the main cause of fabric rolling crooked and the pull bar dragging.
- Cut the top track to the measured opening, not to the length of the old screen or the kit's nominal size.
- Shim behind the housing and latch rail to correct jamb bows; never bend the extrusion to fit.
- Set spring tension so the screen retracts at a slow, controlled speed. Too much tension causes slamming and wear.
- Pre-drill aluminum and wood, and use the screws supplied or stainless equivalents.
Most kits follow the same pattern: a vertical housing (cassette) containing a spring-loaded roller, a top guide track, a pull bar with a handle, a latch rail or strike on the opposite jamb, and either a low-profile bottom guide or no bottom track at all. Pleated screens use a similar layout with a folding mesh and guide cords. Read the product overview in retractable screen doors if you are still choosing. Your kit's instructions take priority over this general method, particularly on screw positions and tension settings.
Tools and materials
- Drill/driver with bits for pilot holes, plus a countersink bit
- Fine-tooth hacksaw or miter saw with a non-ferrous blade for cutting aluminum
- Metal file or deburring tool
- 2 ft and 4 ft (0.6 and 1.2 m) levels, tape measure, pencil, combination square
- Composite or plastic shims (thin, 1/32-1/8 in, about 1-3 mm)
- Exterior sealant if mounting to brick or a build-out frame
- Screws supplied with the kit, or stainless replacements of the same size
- Masking tape to mark positions on painted trim
Before you start: three checks
Retractable screen doors are less forgiving than hinged screen doors, because the screen runs in fixed guides. Ten minutes of checking saves an hour of fiddling.
- Confirm the size. Re-measure the opening at three widths and three heights and compare with the kit's size range. The method is in how to measure for retractable screens. Kits are usually sold to fit a range, such as up to about 36-37 in (914-940 mm) wide by 80-82 in (2032-2083 mm) high for standard doors, and you cut them down.
- Check flat jamb or trim depth. The housing needs a flat surface wider than its own depth. If the jamb is narrow or has a rounded edge, mount to the outside trim face instead, or add a build-out strip.
- Check door hardware clearance. Open and close the main door. The handle, deadbolt and any storm-door closer brackets must clear the path of the screen's pull bar. Remove old storm-door hardware and fill the holes.
Choose which side the housing goes
The housing can usually go on either side. Common practice is to put it on the hinge side of the main door so the pull bar latches at the handle side, which means you reach for the screen and the door handle in the same place. If a wall or railing is close on one side, put the housing there so the pull bar travels toward open space. Some kits flip by turning the housing upside down; check before you cut, because the top track is often handed.
Installation steps
- Measure and cut the top track. Measure the opening width at the top, between the faces you will mount the housing and latch rail on. Subtract the deductions given in the kit instructions (these account for the housing and rail widths). Cut the top track square with a fine-tooth blade, and deburr both ends so the screen's top guide does not catch.
- Cut the housing and latch rail to height if required. Many kits ship the housing slightly long. Cut from the end specified in the instructions, usually the bottom, so you do not disturb the spring mechanism at the top. Some housings must not be cut at all; in that case, the sill adapter or top track takes up the difference.
- Dry-fit the frame. Assemble the housing, top track and latch rail loosely and hold them in the opening. Check that the screen will clear the threshold and that the top track sits flush against the head jamb or trim.
- Fix the housing plumb. Hold the housing against the jamb, place a level on its face and side, and drive the top screw through a pilot hole. Check plumb again in both directions, shim behind any low spots, then drive the remaining screws. Do not overtighten: crushing the housing distorts the roller.
- Fix the top track. Slide the top track onto the housing connector and fasten it to the head jamb with the screws supplied. Check it is level and not bowed; shim above it where the head jamb dips.
- Fix the latch rail or strike. Pull the screen across to the latch side and engage the pull bar in the latch rail. Hold the latch rail plumb and parallel to the housing, then fasten it. Parallel matters more than perfect plumb here: if the housing and rail are parallel, the screen closes evenly top to bottom.
- Install the bottom guide or sill adapter. If your kit has a bottom guide, set it on the threshold, square to the jambs, and fasten or bond it per the instructions. On sloped thresholds, use the supplied adapter so the guide is level.
- Adjust spring tension. Most housings have a tension adjuster at the top. Turn it in small increments, testing after each change. The screen should retract fully at a walking pace and stop gently. Pleated and brake-equipped screens may have a speed governor instead.
- Adjust the latch. Move the strike or magnet catch so the pull bar seats firmly without having to be pushed hard. Magnetic catches should pull the bar the last 1/4 in (6 mm) on their own.
- Fit end caps and seal. Snap on end caps, fill any screw holes in brick or build-out frames with sealant, and run the screen 20 times to check it tracks without rubbing.
Common problems and fixes
| Symptom | Likely cause | Fix |
|---|---|---|
| Screen slams back into the housing | Too much spring tension, or speed brake not engaged | Reduce tension a few turns; check brake setting |
| Screen will not fully retract | Too little tension, or top track rubbing | Add tension; check track is straight and deburred |
| Pull bar does not latch at the top or bottom | Housing and latch rail not parallel | Re-shim the latch rail until the gap is even |
| Fabric creeps to one side | Housing out of plumb | Re-plumb the housing |
| Gap at the bottom lets bugs in | Sloped threshold, missing sill adapter or brush | Fit sill adapter; add or adjust bottom brush seal |

Double doors and wide openings
For French doors, fit two housings, one on each jamb, with pull bars that meet in the middle, or a single wide housing on one side. Meeting pull bars must line up exactly; mount one side completely, then mount the second housing and adjust its position until the bars meet evenly over their full height. See retractable screens for French doors for configuration choices.
Frequently asked questions
Can a retractable screen door go on an out-swinging door?
Usually it goes on the inside face of the opening for out-swinging doors, because the screen must sit on the side opposite the door swing. Check that the interior trim is flat and wide enough, and that the door handle clears the pull bar.
Do I need to remove my storm door first?
Yes. The storm door's frame occupies the same jamb or trim surface the screen needs. Remove it, take off any Z-bar frame, and fill the screw holes before measuring for the screen.
How do I cut the aluminum tracks without burrs?
Use a fine-tooth blade (24 teeth per inch or more on a hacksaw, or a non-ferrous blade on a miter saw), cut slowly, and finish with a file or deburring tool. Wear eye protection; aluminum chips fly.
Can I install a retractable screen door on a brick opening?
Yes, but the brick is rarely flat or plumb enough. Most installers fit a build-out frame of PVC or treated wood with masonry anchors, then mount the screen to that.
What if my threshold is higher than the floor outside?
That is normal. Measure height to the top of the threshold and use the sill adapter or bottom brush the kit provides. Some kits have no bottom track at all, which is easier on uneven thresholds.
How often does spring tension need adjusting?
Usually only in the first few weeks as the mechanism settles, then rarely. If the screen starts to slam or fail to retract after years of use, check for dirt in the tracks before adding tension.
