Choosing a Colorbond Fence Installer: What the Cheap Quote Leaves Out

You have three quotes for a new Colorbond fence. Two land within a few hundred dollars of each other. The third is $1,500 cheaper. Same colour, same height, same length of fence. So what is the catch?

Colorbond panels look much the same no matter who installs them. That is exactly why the cheap quote is so tempting, and why the difference between installers is so easy to miss. The gap is almost never in the sheeting. It is in the work you cannot see on the day the fence goes up: the checks before digging, the depth of the footings, how the steel is cut, what happens to the old fence and what paperwork backs the job.

Those things decide whether your fence still stands straight in ten years or starts leaning after the first wet winter. If you are comparing quotes and want a sense of what a fair Colorbond steel fence price looks like, it helps to first understand what you are actually paying for. Here is what good fencing contractors do as standard, and what the cheapest operators tend to leave out.

  1. They check the boundary and what is underground first

A good installer does not assume the old fence was in the right place. Where there is any doubt, they will ask to see your title plan or suggest a survey before a single post hole is dug. Building a new fence on the wrong side of the line is an expensive mistake, and it is usually the neighbour who notices.

They will also lodge a Before You Dig Australia (BYDA) enquiry to locate gas, water, power, stormwater and NBN services. It is free, it takes a little time, and it protects you from damaged pipes, cut cables and genuinely dangerous situations.

What cheap installers skip: they follow the old fence line and start digging straight away, hoping nothing is down there.

  1. They help you handle the neighbour and council side

Most boundary fences are shared, and in Victoria the Fences Act 1968 sets out how the cost and the decision-making should be split between neighbours, including the use of a formal fencing notice. A professional installer understands this process and can give you the information you need to have that conversation properly.

They will also flag anything that might need council input: height limits, heritage or neighbourhood overlays, sightline requirements on corner blocks and driveways, and pool barrier rules if the fence forms part of a pool enclosure.

What cheap installers skip: “That is between you and your neighbour.” Then the fence goes up, a dispute starts, and you may be the one paying to change it.

  1. They remove the old fence properly

Taking down an old fence is part of the job, not an afterthought. A good company will itemise removal and disposal in the quote and take old timber, sheeting and concrete footings away to be disposed of or recycled correctly.

Older fences, especially fibro fences from before the 1990s, may contain asbestos. A responsible installer will recognise the risk and arrange a licensed asbestos removalist rather than breaking up sheets with a crowbar in your backyard.

What cheap installers skip: removal is left off the quote and added later, or old materials end up dumped on the nature strip.

  1. Footings and posts are built for the soil, not the budget

This is the single biggest difference between a fence that lasts and one that fails. Colorbond panels act like a sail in strong wind, so everything depends on the posts and the concrete holding them.

A quality installer will:

  1. Dig holes to the right depth and diameter for the fence height, soil and exposure. For a standard 1.8 m fence that is typically around 600 mm or more, and deeper in reactive clay or windy sites.
  2. Use enough concrete, properly mixed and set, rather than a shallow dry-pack.
  3. Space posts to the manufacturer’s specification and set every post plumb and in line.

Many Melbourne suburbs sit on reactive clay that swells when wet and shrinks when dry. Shallow footings in that soil move, and the fence moves with them.

What cheap installers skip: shallow holes, minimal concrete and posts spaced wider than they should be to save materials. The result is leaning panels after the first big storm or a wet winter, which is the most common failure we see on budget jobs.

  1. They deal with slopes, retaining and drainage

Very few backyards are perfectly flat. A good installer will step or rake the panels to follow the ground neatly, and will plan for any change in level between your yard and your neighbour’s.

Where soil needs to be held back, they will install proper plinths or retaining sleepers so that soil, mulch and garden beds are not sitting against the steel. Colorbond is designed to resist the weather, not to be buried. Constant contact with damp soil traps moisture and leads to early corrosion along the bottom of the panels.

What cheap installers skip: panels run in a straight line regardless of the slope, leaving big gaps underneath, or soil is simply piled against the bottom rail.

  1. They cut and fix Colorbond the way the manufacturer intends

How the steel is handled on site matters more than most people realise. Abrasive cutting discs throw hot metal particles that can burn into the painted finish, and the tiny metal filings left behind (called swarf) rust quickly and leave orange stains across your new fence.

A professional installer will:

  1. Use cutting methods that are recommended for pre-painted steel and keep abrasive discs away from finished panels.
  2. Sweep and brush off swarf from panels, rails and caps at the end of each day.
  3. Use matching rails, caps and fixings, installed to specification.

What cheap installers skip: grinder-cut on site, filings left on the panels, and mismatched components. You end up with rust spots within months, and you may find it harder to rely on the materials warranty.

  1. They use genuine materials and can prove it

“Colorbond” is a registered brand of steel, but not every coloured steel fence is made from it. Some budget quotes use lookalike products or thinner steel that dents easily and does not carry the same warranty.

A good installer will tell you exactly what product they are using, who manufactures it, which colour range it comes from and which warranty applies. If you live near the coast or an industrial area, they should also tell you whether your site needs a specific product or has different warranty conditions.

Tip: ask which manufacturer’s warranty applies to your fence and what the installer must do to keep it valid. A confident, specific answer is a good sign.

  1. The quote is itemised and the paperwork is real

A professional quote is written and detailed. It should list the total length and height, the panel colour, the number and type of gates, removal and disposal of the old fence, footing details, any plinths or retaining, and clean-up.

Behind the quote you should also see:

  1. A registered business name and ABN on the quote and invoice.
  2. Current public liability insurance, which they should be happy to show you.
  3. Any licences or registrations required for the work in your state.
  4. A written workmanship warranty, separate from the materials warranty.

What cheap installers skip: a one-line text message quote, a cash price, no ABN and nothing in writing if something goes wrong.

  1. They finish the job properly

The last day of the job says a lot about an installer. Gates should be hung square, swing freely and latch cleanly, with quality hinges and latches suited to the gate size. Where a gate forms part of a pool barrier, it needs to be self-closing and self-latching.

The site should be left clean, with concrete spoil, offcuts, packaging and swarf removed. A good company will walk the fence line with you at the end, check you are happy and explain how to care for your new fence.

What cheap installers skip: spoil heaps left in the garden, sagging gates and a phone that stops being answered once the final payment clears.

Quick checklist: questions to ask before you sign

Take this list with you when you compare quotes:

  1. How deep are your post holes, and how much concrete goes into each one?
  2. Is the steel genuine Colorbond, and which warranty applies to my fence?
  3. How do you cut the panels, and how do you clean up metal filings?
  4. Is removal and disposal of the old fence included in the price?
  5. Can I see your public liability insurance and a written workmanship warranty?
  6. Who handles the Before You Dig enquiry and any neighbour or council requirements?
  7. How will you deal with the slope and any soil against the fence line?

If an installer cannot answer these clearly, the lower price is probably coming out of one of these steps.

The cheapest quote is rarely the cheapest fence

A Colorbond fence should give you decades of low-maintenance privacy and security. When it is installed well, it does. When corners are cut on footings, cutting, materials or paperwork, the savings disappear quickly in repairs, replacement panels, neighbour disputes or a full rebuild.

So when you line up your quotes, compare them line by line rather than on the bottom figure alone. Use the checklist above, ask for everything in writing and choose the installer who can explain their process with confidence. Paying a fair Colorbond steel fence price up front is almost always less than paying twice.
