Doors

Made to measure. Made to last.

No stock sizes, no subcontractors. We measure your opening at the house, build the door in our Preston workshop, then the same installer comes back and hangs it — square, smooth and properly locked.

Pick from the standard Dulux colour range, timber-look finishes, or give us any custom colour and we'll powder-coat to match.

Windows

Windows open. Family safe.

Stainless mesh window screens give you airflow all summer with nothing compromised — the window stays open, the house stays sealed.

Most parents start with the kids' bedrooms. Once you've slept with the windows open in January, you'll do the rest of the house.

Why Locked Security Doors

One team. Start to finish.

The person who measures your door works in the workshop that builds it and comes back to install it. That's why the fit is right and the warranty is easy to honour.

Built in Preston

Every door and screen comes out of our own northern-suburbs workshop — not a container.

10,000+ installs

Two decades of doors, screens and windows in every shape an old Melbourne house can throw at us.

Straight answers

Firm quotes on the spot, honest advice on what you do and don't need.

Tradesman-owned

Run by the bloke on the tools, not a sales office.

7-year warranty

If something's not right, the people who made it come and fix it.

Standards-beating

Doors built to exceed AS5039 — tested mesh, real locks, proper frames.
