Locked Security Doors brings over 25 years of manufacturing experience to Melbourne's northern suburbs.
Locked Security Doors exists because too many security doors are sold by salespeople and fitted by whoever's available. We do it the old way: the tradesman who measures your door is the one who installs it. That tradesman is Franz, ex-carpenter, ex-commercial construction manager, owner of this business, and a card-carrying perfectionist. If a door isn't sitting perfectly square, it gets fixed before he leaves.
The doors themselves are Australian made by specialist factories we know personally and have worked with for decades. We're based behind High Street in Preston, and our service area is the suburbs we actually live in: Melbourne's north. Quick site visits, honest lead times, and a warranty backed by people you can find.
Behind the brand is over 25 years of manufacturing experience and more than 10,000 doors and screens fitted across Melbourne.
Every security door is made in Australia by specialist fabricators we've trusted for decades.
Every opening measured on site before anything gets made. It's why our doors don't rattle.
Long enough to mean something, backed by the people who built the product.
Old terraces, new builds, odd-sized openings, we've fitted them all.
Real fabrication and installation experience, not a sales script.
Based in Preston, servicing the north. If we're not nearby, we don't take the job.
Owner & Lead Installer. Preston local Franz started as a chippy, then spent years running large commercial builds as a project manager and construction manager, so he's a perfectionist about measurements, schedules and finish in a way only ex-construction people are. Security doors run in the family too: his brother-in-law and their dad have been manufacturing and installing them for decades. Franz has personally fitted thousands of doors across Melbourne, and if you book a quote, he's the one knocking on yours.
Measure & Install. Another ex-construction manager who swapped site sheds for security doors. Scott measures and fits across the north with the same eye for detail Franz has, which is saying something. Between them they've run jobs a lot bigger than your front door, and it shows in the finish.
Security Consultant (Canine Division). Minty rides shotgun in the van on most jobs. Duties include perimeter inspections, supervising the install from a respectful distance, and personally testing every pet door we fit. Yet to approve a dodgy hinge.
