Hanging a Door Properly: What's Involved

Hanging a door looks simple. It isn't quite.

Swapping a door sounds like a quick job — take the old one off, put the new one on. In practice, hanging a door properly is a precision task, and it's one of those jobs where small errors are glaringly obvious. A door that catches on the frame, won't latch, or swings by itself is the result of millimetres being out. Here's what's genuinely involved so you know what you're taking on.

Step one: check the opening

Before touching a door, you check the frame. Is it plumb (vertically level), square, and the right size? Especially in older Melbourne homes, frames settle and shift over decades, so openings are often out of square. This single check determines whether the job is straightforward or fiddly. Skip it and you'll be chasing problems later.

Step two: size the door

New doors usually need trimming to fit the opening precisely. That means:

• Measuring the opening at top, middle and bottom, since they're rarely identical.
• Planing or trimming the door evenly on the correct edges.
• Maintaining consistent clearances — a few millimetres around the sides and top, a bit more at the bottom.
• Easing the leading edge slightly so it doesn't bind as it closes.

Trim too much and you can't undo it, so this is measure-twice territory.

Step three: hinges

Hinge work is where accuracy really counts:

• Position: Hinges must line up exactly between door and frame.
• Mortising: Each hinge sits in a recess (a mortise) chiselled or routed so it's flush. Cut too deep and the door binds; too shallow and it won't close.
• Fixing: Screws must bite into solid timber; long screws into the frame stud help heavier doors hang without sagging.

Most internal doors use two or three hinges. Heavier solid-core and external doors need three or more to carry the weight.

Step four: the latch and handle

The latch bore and the strike plate on the frame have to align perfectly, or the door won't catch. This means marking and cutting the handle position on the door and the matching mortise and strike plate on the frame. A latch that misses the strike by even a couple of millimetres means a door that won't stay shut.

Step five: hang, test and adjust

With hinges and latch fitted, the door goes on and the real test begins. You're checking that:

• The gap around the door is even all the way around.
• It closes smoothly without catching.
• It latches cleanly and stays shut.
• It doesn't swing open or closed on its own.

Fine adjustment — packing behind hinges, easing edges, tweaking the strike — is normal at this stage. A well-hung door should feel effortless.

Common Melbourne quirks

Period homes across Melbourne throw up recurring issues: out-of-square frames from a century of settling, painted-over hinges on original doors, and non-standard door sizes that pre-date modern off-the-shelf dimensions. These aren't dealbreakers, but they turn a "quick swap" into a proper carpentry task.

When to get a hand

If your opening is square and standard, a confident DIYer can hang a door with patience and the right tools. If the frame is out of square, the door is heavy, or you've got several to do, it's slow, exacting work where mistakes show.
