Screen Door Repair: Fixing Tears, Rollers & Sag
A ripped screen lets bugs in and undoes the whole point of leaving the door open for a breeze. Sliding screens often jump the track or drag because the little rollers are worn, and hinged storm-door screens can sag, bind, or slam thanks to a tired closer. In coastal and humid SC weather you also get pets, sun, and salt air wearing the mesh and hardware down faster than you'd expect.
Screen door repair covers a few related problems, and the fix depends on which one you have. Re-screening means pulling the old mesh and rolling new screen into the frame's groove with spline, choosing a mesh that suits the use, like a tougher pet-resistant weave where dogs lean on it. Sliding doors that won't glide usually need new rollers and a cleaned or straightened track, while hinged doors need hinge, closer, and latch adjustments so they shut snugly without banging. The goal is a door that rolls or swings smoothly, latches on its own, and keeps insects out.
How the job is done
- 1
Diagnose the failure
We figure out whether the issue is torn mesh, bad rollers, a bent track, sagging hinges, or a worn closer, since each needs a different fix. Often a sticking door has more than one of these going on.
- 2
Remove old screen or hardware
For re-screening, the old spline is pried out and the torn mesh discarded, exposing the frame groove. For a slider, the door is lifted out of the track to reach the roller assemblies underneath.
- 3
Install fresh mesh with spline
New screen is laid over the frame and rolled into the groove with a spline tool, keeping the weave square and taut without overstretching. Excess mesh is trimmed flush along the spline.

Replace rollers and clean the track
Worn rollers are swapped for new ones matched to the door, and the track is cleared of grit and straightened if it's pinched. Clean, true tracks are what let the door glide with one finger.
- 5
Adjust hinges, closer, and latch
On a hinged storm or screen door we square up sagging hinges, set the pneumatic closer so it shuts firmly without slamming, and align the latch to catch on its own.

Test the full operation
We roll or swing the door through its range, confirm it seals against bugs, and verify it latches and closes the way it should before we're done.
What a pro checks
- Pet-resistant and heavier mesh stands up to dogs, claws, and busy doorways far better than standard fiberglass screen.
- Spline that's too thick or too thin won't hold the mesh; matching the spline size to the frame groove is what keeps it tight.
- A slider that jumps the track is usually worn rollers or grit in the channel, not a warped door.
- Coastal salt air and strong sun degrade screen and hardware over time, so coastal homes tend to re-screen more often.
- Overstretching the mesh while splining warps the frame and leaves the screen wavy; even tension is the trick.
- A storm-door closer that slams or won't latch is adjustable; the tension screw and mounting bracket set how it shuts.

Frequently asked questions
Can a torn screen be patched, or does it need full re-screening?
Small holes can sometimes be patched, but a long tear, brittle sun-damaged mesh, or a door that gets heavy use is better off re-screened entirely. Fresh mesh in the frame lasts far longer than a patch.
Why won't my sliding screen door glide anymore?
Most often the rollers at the bottom are worn or the track is full of grit or slightly bent. Replacing the rollers and cleaning or straightening the track usually brings the smooth glide back.
What kind of screen is best if I have pets?
A pet-resistant or heavier-gauge mesh holds up much better to claws and pets leaning on the door than standard fiberglass. It costs a bit more but saves repeat repairs in a busy doorway.
My storm door slams shut. Can that be fixed?
Yes. The pneumatic closer that controls the swing is adjustable, and the hinges and latch can be realigned so the door closes firmly and latches without banging. It's a common, quick adjustment.
