Perth summers bring two things in reliable numbers: hot afternoons that make you want the back door open, and flies that are determined to get inside. That’s when a torn screen or a sliding door that keeps jumping its track really starts to grate.
The good news is that most fly screen faults don’t need a brand-new door. A few quick checks will tell you whether a repair will do the job, whether replacement makes more sense, or whether it’s time to step up to a proper security screen.
Start With the Mesh
Torn mesh is the most common fault by a long way. Pets push through it, kids lean on it, and years of UV make some meshes brittle.
If the frame is still straight and the door runs smoothly, re-meshing is usually all you need. It’s also a chance to choose a better mesh:
-
Fibreglass: the standard choice, flexible and won’t corrode
-
Aluminium: stiffer and holds its shape well
-
Pet mesh: thicker and far more tear-resistant for dogs and cats
-
One-way privacy mesh: harder to see through from outside, though it works best when it’s brighter outdoors than in
Sliding Screen Off Its Track? Check the Rollers
A screen that feels heavy, grinds, or drops out of its track usually has one of three problems: sand packed into the track, rollers adjusted too low, or rollers that have simply worn out.
Vacuum the track and scrub the corners with a stiff brush first. If there are small adjustment screws at the bottom of the frame, try quarter-turns and test the slide after each one. If it still drags, the rollers are the likely culprit, and that’s exactly the kind of door repair Perth homeowners can usually sort out without buying a new door. Whatever you do, don’t keep forcing it. That’s how a cheap roller job becomes a bent frame.
Check the Frame and Hardware
Close the door and look at the gaps. Uneven spacing, loose corners or a visible twist mean the frame has moved. In coastal suburbs, check for corrosion at the joints too.
Handles, catches, hinges and closers wear out with daily use, but they’re usually cheap to replace on their own. A bent frame is different: it won’t hold new mesh tight or line up with the lock, so repairs rarely last.
Fly Screen or Security Screen? Know the Difference
This is where many people get caught out. A standard fly screen keeps insects out and lets air in. Even with a lock and a metal frame, it isn’t designed to stop someone forcing their way through.
A genuine security screen is built and tested for that purpose. In Australia, performance is covered by AS 5039.1:2023 and installation by AS 5039.2:2024. The whole system matters, including the mesh, frame, locks and fixings, not just the screen material.
Not all of the security fly screens Perth retailers advertise are tested to that standard, so ask for written evidence of compliance rather than trusting labels like “heavy-duty”.
When Replacement Makes More Sense
Replacing the door is usually the better call when:
-
The frame is bent, twisted or badly corroded
-
The same parts keep failing after repairs
-
Replacement parts are no longer available
-
Repair costs are getting close to the price of a new door
-
You want to upgrade to a compliant security screen
Openings in older Perth homes are often slightly out of square, so a made-to-measure door will seal far better than an off-the-shelf one.
Why a Repair-First Assessment Helps

A technician who inspects the whole door, from mesh and rollers to track and locks, can tell you honestly whether it’s worth saving. Easy Door Solutions, for example, handles roller and track repairs and re-meshing, plus custom-made fly screen doors Perth households can choose in fibreglass, aluminium or pet mesh. It also offers security screen options, with no call-out fee for the visit.
Frequently Asked Questions
Can a torn fly screen door be repaired?
Yes. If the frame is straight and the door operates properly, the old mesh can be removed and new mesh fitted into the existing frame. Re-meshing is usually much cheaper than replacing the whole door.
Why does my sliding fly screen door keep coming off its track?
The most common causes are sand or debris in the track, rollers set too low, worn rollers or a bent track. Clean the track and adjust the rollers first. If it keeps happening, the rollers or track need replacing.
Is it cheaper to repair or replace a fly screen door?
Repair is usually cheaper when the frame is sound and the problem is limited to mesh, rollers or a handle. Replacement offers better value when the frame is bent, parts are unavailable or the door keeps failing.
What is the difference between a fly screen and a security screen?
A fly screen keeps insects out while allowing airflow. A security screen also resists forced entry and, in Australia, should be tested to AS 5039.1:2023 and installed to AS 5039.2:2024.
What is the best fly screen mesh if you have pets?
Pet mesh is the best choice for homes with dogs or cats. It’s thicker and much more tear-resistant than standard fibreglass, though it isn’t a security mesh.
How often should I clean my fly screen door?
Vacuum the track every few weeks during summer, more often in sandy or coastal areas, and wash the mesh with a soft brush and mild soapy water a few times a year. Avoid oily lubricants, which attract sand.
Can I put security mesh in my existing fly screen frame?
Usually not. Standard fly screen frames aren’t built to carry security mesh, and a compliant security screen depends on the frame, locks and fixings working together as a tested system.
Final Thoughts
Most fly screen problems in Perth come down to mesh, rollers or hardware, and all three are usually repairable. Check the frame before you buy anything new, and if security is part of the brief, insist on a properly tested product rather than a tougher-looking fly screen.
