The best time of year for security screens in Wollongong.

The best time of year to get security screens in Wollongong is late autumn through winter, roughly May to August. Demand across the Illawarra collapses once the mosquitoes stop, so lead times are at their shortest and you get an unhurried measure instead of a queue. The worst time is October through January, when every household in Wollongong decides at once that it wants flyscreens, and a two-week turnaround becomes five or six.

It is a completely predictable cycle and it is driven by weather, not by marketing. Wollongong sits in a warm-temperate coastal pocket with humidity that climbs from October, and the mosquito season around the Lake Illawarra and Mullet Creek wetlands runs hard from November to March. The moment the first warm evening arrives and people open a window, the phones start. By late November the fabrication queue across the region is full, and it stays full until the school holidays end.

One thing that does not affect your timing: council. Fitting security screens and screen doors to an existing house is exempt development across the Wollongong City Council area under the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008, so there is no application to lodge and no approval queue to sit in at any time of year. Heritage-listed properties are the exception and should check with council first. The only genuine waits are the fabrication queue and, if you are in a unit, your owners corporation. Both are shorter off-season.

What the queue costs you, in weeks.

In the November to January peak, expect roughly four to six weeks from measure to installation across most Illawarra installers, because custom doors are made to your opening and the fabrication queue is full. In June or July the same job is commonly two to three weeks. Nothing about the door changes, only the queue in front of it.

Worth being clear about why that is unavoidable rather than a scheduling failure. A security door is not pulled off a shelf. It is cut, welded, meshed and powder-coated to the millimetre dimensions of your opening, and on the coast to the mesh grade your street needs. That fabrication step is where the queue sits, and in December it is full of everybody else’s doors.

The materials are not. Mesh, frame and hardware cost the same in July as in December, and anyone claiming a big winter discount is either padding the summer price or cutting something. What genuinely changes off-season is availability and attention: shorter lead times, more flexible install dates, and time to properly assess your salt exposure and egress requirements rather than rushing the measure.

What the unhurried measure actually buys is worth naming, because it is the real argument for the off-season. In May there is time to work out which AS 4312 atmospheric corrosivity zone your street sits in, which is what decides the mesh grade and which swings hard between the beachfront and the escarpment. Time to confirm the product is AS 5039 certified and tested to AS 5041 rather than being a flyscreen door with a deadlock in it. Time to fix it to AS 5040, which is the standard that decides whether that certification survives contact with your wall. And time to check whether an upstairs bedroom window needs NCC 2022 Volume Two fall protection, or whether a bedroom screen needs a quick-release egress hinge, which is set out on the fire egress rules page. In December all of that gets done at pace. Same door, same price, less thinking.

We would rather say that plainly than run a fake winter sale. A 316 marine-grade hinged door is $900 to $1,400 supplied and installed in any month of the year. A flyscreen is $90 to $160 in July and $90 to $160 in January. The whole itemised list sits on the pricing page and it does not have a seasonal column.

A worked example of what timing really buys.

A family in Figtree wants the lot: a front hinged 304 stainless door with triple-lock at $1,050, three bedroom window screens with quick-release egress at $340 each, $1,020, and four flyscreens at $130 each, $520. Total $2,590 supplied and installed either way. Booked in mid-June, the measure happened that week and the install landed about a fortnight later, all done by early July. Booked in mid-November, the identical job would have been measured a week or two out and installed somewhere in the back half of December, which is precisely the six weeks they wanted the screens for. Same money. Very different summer.

No, you should not wait until summer so you can test the airflow, and this is the most common reason people end up waiting in the summer queue. You cannot meaningfully test airflow before you buy, and the difference between mesh types is modest anyway. Fitting in winter means the screens are already on the house when the first warm north-easterly arrives in October, rather than being six weeks into a fabrication queue while you sleep with the windows shut.

Woven stainless gives slightly more see-through and breeze than punched aluminium, and both are dramatically more open than the old diamond grille doors they replace. That is the whole of the airflow story, and it is set out properly on the stainless vs aluminium page. It is not a decision that improves by being made in February.

One genuine timing exception: retractable flyscreens on a bi-fold or a large opening are worth seeing in place before a summer of heavy use, so if a big opening is on your list, the earlier the better. If that opening is a patio or balcony slider, the sliding security doors page covers the locking spec that actually matters on it, and screen maintenance covers keeping the track clear once it is in. Suburb notes are on Corrimal, Fairy Meadow, Unanderra and Dapto, and if you are weighing installers, start with how to choose.
