If you already have a driveway gate you like, automating it is usually cheaper than starting again. But whether your particular gate is a good candidate depends on things you can check yourself with a tape measure, a piece of string and your phone camera. Doing these checks before you ask for quotes means you will understand what installers are telling you, and you will be able to send the right photos the first time.

This is the practical, owner's side of the job. For how we actually carry out a retrofit, see our Gate Automation Retrofits service page.

Check 1: the push test

Undo any latch or drop bolt and move the gate through its full travel by hand, slowly, then again at a normal walking pace.

Good: it moves with steady, light pressure from one hand and does not need lifting at any point.
Needs work: it catches, drags on the ground, needs a lift to latch, or swings open or closed on its own.

A swing gate that drifts open or closed by itself usually means the hinges are not vertical, or the post has leaned. A sliding gate that is heavy at one point usually has a worn wheel, a bent track or debris in the track. None of these is a deal-breaker, but a motor will not cure them.

Check 2: is the gate straight?

Run a string line along the top rail and look for a bow. Then measure the two diagonals of each leaf, corner to corner. If they differ by more than a small amount, the frame has racked. On a timber gate, look for twist by sighting along it from one end.

A racked or twisted gate will bind as it closes and trip the motor's safety cut-out. Steel and aluminium frames can often be squared up. A timber gate that has twisted badly may need a new frame, or it may be the point where replacing the gate makes more sense.

Check 3: hinges and posts

Grab the end of each swing leaf and try to lift it. Movement at the hinges means worn pins or bushes. Then push against each post in both directions. Any rocking in the ground is a problem, because a motor applies the same force every cycle and a loose post only gets looser.

This matters around Geelong because both local soils are hard on posts. Clay in suburbs like Highton and Belmont swells and shrinks with the seasons, and the sandy ground toward Ocean Grove and Leopold offers less grip. Posts that have moved are usually re-set in new concrete footings, and on heavy gates we often replace the post altogether.

Check 4: roughly how heavy is it?

You do not need an exact figure, but note the material, the size of each leaf and whether it is solid or open. A solid timber or steel-clad gate weighs far more than open aluminium slats of the same size, and wind load on a solid gate adds to the effort. Motors are chosen by gate weight, leaf length and how many times a day the gate will run, so this shapes the quote more than almost anything else.

Check 5: room for the hardware

For a swing gate, measure the gap between the back of the hinge post and any wall, fence or garden bed behind it, and check the ground the leaves swing over. A driveway that rises inside the gate can stop the leaves opening fully. Swing gates should open into your property, not out over the footpath.

For a sliding gate, measure the clear run beside the opening, which needs to be at least as long as the gate, and check there is a flat spot near the post for the motor to sit on.

Check 6: where will the power come from?

Find the nearest power point or switchboard and pace out the distance to the gate. A short run in a suburban block is simple, but new mains wiring must be done by a licensed electrician. On the Bellarine and around the rural edge of Geelong, gates are often too far from the house for a cable to be worth it, and a solar motor is the usual answer. Our post Solar-Powered Gates for Bellarine Acreage Properties explains how to size one so it keeps running through winter. If you choose solar, note whether the gate gets sun through the day.

What usually gets replaced

Even when a gate is a good candidate, a few parts are almost always changed:

Latches and drop bolts come off or are disabled, because the motor holds the gate closed. An electric lock can be added where extra security is wanted.
Hinges are often upgraded to heavier, adjustable ones so the leaf hangs true.
Gate stops are fitted so the gate always closes to the same point.
Wheels and guides on sliding gates are replaced if worn, and a rack is fixed along the gate.
Spring closers or anything that pushes the gate on its own are removed.

What to send for a quote

A good set of photos saves a site visit or two. Take:

The whole gate from the street, closed
The whole gate from inside the property
Each hinge or the track and wheels up close
The base of each post
The area beside the opening where a motor or run-back would go
The nearest power point, with the gate in the background if possible

Add your measurements from the checks above and a note of how often the gate will be used.

Should you automate it at all?

If your gate passes most of these checks, automating it is almost always worthwhile. If it fails several, or the gate needs a new frame and new posts, a new gate designed for a motor may cost little more and last longer. Our guide What an Automatic Gate Actually Costs in Geelong gives the broad ranges for both paths.

Whether you are in Highton, Belmont, Leopold, Ocean Grove or Torquay, send us your photos and measurements and we will tell you honestly which way to go.
