A sliding screen door rides on spring-loaded rollers with tension screws at the corners. When the springs weaken or the wheels break, the door drops, jams and jumps the track. We replace the rollers and re-track the door, re-mesh a torn screen if the frame is straight, or fit a new door, including heavy-duty frames and pet-resistant mesh.
What you get
- New spring-loaded rollers top and bottom, tension set so the door glides and stays on
- Screen track cleaned and straightened, bent frame corners checked
- Torn mesh replaced in the existing frame when the frame is straight
- New screen doors, standard and heavy-duty, made to the opening
- Pet-resistant mesh and heavy frames for dogs and cats
Why screen doors jump the track
A sliding screen door is a light aluminum frame on four small rollers, two at the top and two at the bottom. Each roller is spring-loaded and sits behind a tension screw at the corner. The spring keeps the wheel pressed on the track; the screw sets how far it sticks out.
When the springs tire or the plastic wheels wear flat, the door sits low and loose. It drags, catches on the track lip, and pops off when it hits a bump or a bit of debris. People then force it, which bends the corner, and now the frame is out of square and nothing fits.
The symptom page covers what you can check first: screen door will not slide.
Rollers, tension and re-tracking
If the frame is straight, the fix is new rollers and a reset. We lift the door out, pull the old rollers from the corners, fit new spring-loaded rollers of the right size and style, and set the tension screws so the door rides level with just enough spring to stay on the track.
We clean the screen track in the sill and head, straighten any bent lip, and check the top guide. A door that was forced often has a bent corner or a kinked track, and we straighten those where we can.
On a heavy or oversized screen the rollers are larger, and on some doors the rollers are top-hung with a bottom guide instead. We bring the common types to every visit.

New mesh or a new door?
Torn or sagging mesh is a re-screen if the frame is straight and the corners are tight. We pull the spline, fit new mesh, roll in new spline and trim. The frame and rollers stay.
A new door makes more sense when:
- the frame is bent, twisted or split at a corner, so it will never sit square on the track,
- the frame is so corroded that the roller housings crumble, which is common within a few blocks of the beach,
- the door is an odd size or style that no longer takes standard rollers,
- you want a heavier frame or pet-resistant mesh anyway.
A standard new screen door is made to the opening and fitted with its own rollers and pull. We also fit new doors where there was never one, if the patio door frame has a screen track.
Heavy-duty screen doors for pets and heavy use
A standard screen door is light and the mesh is fiberglass. One dog leaning on it bends the frame; one cat climbing it shreds the mesh.
For homes with pets or heavy traffic we fit a heavy-duty door: a thicker extruded aluminum frame, larger rollers, and a pet-resistant mesh woven from heavier coated strands that stands up to claws. The door weighs more and takes a firmer push, but it stays square and stays on the track.
We can also add pet-resistant mesh to an existing heavy frame as a re-screen. On a light frame it is not worth it, because the frame goes before the mesh does.
This is the usual request from homes with dogs and a yard, which describes a lot of Poway and Santee.
Screen door or patio door: which one is the problem?
Sometimes the screen is only the messenger.
- If the screen jumps the track in the same spot every time, check the sill for a bent lip or debris. A bent screen track is fixable; a screen forced over it bends too.
- If the glass panel next to it has dropped, the screen can rub the handle or the frame of the glass panel. The fix is the glass door rollers, not the screen.
- If the screen will not latch, the small screen latch or its strike is worn or misaligned, and we replace it along with the rollers.
Rollers on the screen door are a small job and an inexpensive one. We do it while we are there for the glass door on most visits, and the price is on the pricing page.
Screen doors across San Diego County
Screen doors matter more here than in most places, because the weather lets you leave the slider open most of the year. Coastal homes in Oceanside and Carlsbad go through screen rollers faster, because salt air corrodes the roller housings and the springs. Inland, sun and heat age the fiberglass mesh until it tears at a touch.
Standard patio screen doors are a stock item for us. Odd sizes, extra-tall doors and screens for multi-slide and pocket doors are made to measure and quoted after a photo.
Send a photo of the door and the corner with the roller, and we will tell you whether it is rollers, mesh or a new door before we come out.
Screen Door Repair and Replacement: common questions
Why does a screen door fall off again and again?
The spring-loaded rollers at the corners have worn or lost their tension, so the door sits low and pops off when it hits a bump. Sometimes a bent track lip or a forced corner is the cause. New rollers with the tension screws set correctly, plus a straightened track, keeps it on.
Can you fix a screen door or do I need a new one?
If the frame is straight and the corners are tight, we fit new rollers and new mesh and the door is good for years. If the frame is bent, twisted, split at a corner or badly corroded, a new door costs less than fighting it. We tell you which from a photo of the door and its corners.
How much is sliding screen door roller replacement?
The screen roller and re-track price is a flat amount on our pricing page, and it is the smallest job we do. It includes new spring-loaded rollers, tension set, the track cleaned and straightened, and the latch checked. A new standard screen door installed is also a flat price there. Odd sizes are quoted from a photo.
Do you make screen doors for pets?
Yes. A heavy-duty screen door has a thicker aluminum frame, larger rollers and pet-resistant mesh that stands up to claws and leaning. For a frame that is already heavy, we can re-screen with pet-resistant mesh alone. For a light standard frame, a new heavy-duty door is the better value.
Can you re-screen a sliding screen door?
Yes, if the frame is straight. We remove the old spline and mesh, lay in new fiberglass or pet-resistant mesh, roll in new spline and trim it, all on site. If the frame is bent or the corners are loose, we recommend a new door instead, because new mesh will not sit flat in a twisted frame.
