What an Automatic Gate Actually Costs in Brighton & Bayside

Ask three bayside Melbourne gate companies for a price and you'll get three very different numbers, because 'an automatic gate' covers everything from a motor added to your existing gate to a custom double swing gate on a grand Brighton frontage. Here's how to make sense of it.

The two very different jobs

Automating an existing gate is the cheaper path by a wide margin. If you already have a sound gate that moves freely, you're paying for a motor, safety sensors, a control board and your choice of controls — not a new gate. Around bayside Melbourne this commonly runs about $1,500–$4,000.

A supplied-and-installed automatic gate is a different order of cost, because you're buying the gate as well. A standard aluminium sliding or swing gate with automation more typically runs from around $5,000 up to $15,000, and a large custom gate, a double, or a cantilever on a prestige Brighton entrance can run $15,000–$30,000 or beyond.

Those are broad ranges on purpose — the point is the category you're in, not a precise figure.

What moves the number

Gate size and weight. A wider, heavier gate needs a bigger motor and stronger pillars, and the gate itself costs more to fabricate. This is the single biggest driver.

The motor and battery backup. A quality serviceable motor with parts available in Melbourne costs more than a throwaway unit, and it's worth it — the cheap motor is the expensive one when it fails in three years and nobody can source a board.

Cabling runs. Power to the gate, and cabling for an intercom or keypad, all cost more the further they run. A gate close to the house and the meter box is cheaper to wire than one at the end of a long drive. The mains connection is done by a licensed electrician, which is a real line item.

Access control. A basic remote is cheap. A video intercom, keypad and app control add genuine cost — worth it for a busy household, but a real part of the number.

Ground and pillars. A sloping driveway, rock or fill all add labour, and heavy gates need properly footed pillars. The unseen groundwork is where cheap quotes quietly save money.

Coastal hardware. In bayside Melbourne the fixings and finish matter — galvanised and marine-grade hardware near the water costs a little more and lasts far longer.

Where cheap quotes find their savings

Almost always in the parts you can't see on the day: an undersized motor run at its limit, lightweight pillars that will lean within a year, skipped or disabled safety sensors, and non-coastal hardware that rusts near the bay. On the bayside foreshore the hardware spec matters — salt air punishes shortcuts.

Questions worth asking every quote

Is the motor sized for my gate's weight and how often I'll use it, and are spare parts available in Melbourne? Are force limiting, safety sensors and battery backup included? What are the pillars and footings? Is the hardware rated for the coastal environment? Who does the electrical connection? Is this a written, itemised quote?

A company that answers those precisely and one that just quotes a headline number are not offering the same thing. The figures here are general bayside indications, not a quote — we price after seeing the site.
