Custom Security Doors That Last
For more than 40 years, the team at Alpha Screens & Glass has been fitting custom security doors to Caloundra homes across hinged front entries, side doors and sliding patios. We measure each door on site and build it to your opening — nothing off the shelf, nothing forced to fit.
For coastal Caloundra properties, we generally recommend Invisi-Gard 316 marine-grade stainless steel, which handles salt air and humidity well. The 7mm diamond grille pattern gives you a lower-cost alternative, and both options include a triple-lock system, colour-matched aluminium frames and the option to add Petway pet inserts or a hydraulic closer at manufacture.
To book a free on-site measure, give the team a call on (07) 5493 9875.

Hardware, Closers & Repairs
The panel is only half the story with a security door — the hardware determines how well it works day to day. These are the extras and services we most often build into a Caloundra job:
- Hydraulic closers set to hold the door at your preferred angle
- Upgraded lock cylinders and keyed-alike front and rear doors
- Petway pet door inserts fitted into the panel at manufacture
- On-site servicing for dropped, sticking or worn existing doors
- Roller, hinge and lock replacements without swapping the full door
Where an existing door has failed, we'll check whether a service call solves it before recommending a replacement. Send us a message when you're ready and we'll take it from there.
