Gutter replacement cost in Australia
Guttering runs $45–$120 per metre installed, or roughly $2,200–$5,800 for a whole house. The cost that catches people is the rotten fascia behind the old gutter — and near the coast, salt air halves how long any of it lasts.
What guttering costs in Australia
Guttering is priced per lineal metre, and the spread across states is wider than most trades because access, roof pitch and local labour rates all feed into it.
- Colorbond steel — roughly $45 to $120 per metre installed, depending on state and profile. The Australian standard choice.
- Zincalume — roughly $48 to $90 per metre. Same steel construction without the coloured finish.
- Aluminium — roughly $65 to $110 per metre.
- PVC — roughly $30 to $45 per metre, and cheap for a reason: it degrades and warps under Australian sun.
- Box gutters — roughly $80 to $150 per metre, because they need a waterproof membrane system and are a considerably more involved job.
- Copper or stainless — $130 to $250+ per metre.
A standard three or four bedroom single-storey home carries roughly 50 to 70 metres of guttering, which puts a full replacement somewhere between $2,200 and $5,800, with a typical project landing near $3,800 including downpipes.
Two-storey homes add 20 to 50% for access alone — the gutter is identical, the ladder work isn't.
Isolated problems — one rusted joint, a sagging bracket, a leaking corner — are genuinely repairable, typically $200 to $600. Widespread rust along the base of the gutter, multiple leaks, or gutters pulling away from the fascia along whole runs means replacement is the better spend. Repairing failing gutters just chases the rust along the run.
What's behind the gutter
The most common unbudgeted cost in gutter replacement is the timber the gutter was hiding.
Fascia boards sit behind the guttering, and a gutter that's been leaking for years has usually been quietly rotting the board it's fixed to. You can't see it until the old gutter comes off — and you can't fix new guttering to rotten timber.
Fascia replacement adds roughly $50 to $120 per metre, and on a badly affected run that can approach the cost of the guttering itself. Metal fascia capping is a cheaper alternative at around $40 to $60 per metre where the timber is sound but weathered.
A good contractor inspects and flags this before quoting rather than halfway through the job. Ask directly: have you checked the fascia condition, and what happens to the price if it's rotten?
Salt air halves the lifespan
This is the Australian variable that international guides never cover, and it materially changes the maths.
Quality Colorbond guttering on an inland home commonly delivers 20 years or more. On a beachfront or near-coastal property, that can drop to 10 to 15 years, because salt-laden air accelerates corrosion regardless of how well the product was installed.
If you're near the coast, two things follow. First, budget for replacement more often than the headline lifespan suggests. Second, ask specifically about product grade — there are higher-grade steel finishes engineered for marine environments, and the premium is generally worth paying within a few hundred metres of the water.
It's also worth washing coastal guttering down with fresh water occasionally. It sounds trivial; it's one of the few things that measurably extends service life in a salt environment.
What a complete quote covers
Per-metre rates are a starting point rather than a final figure, because a gutter system is more than straight runs.
Downpipes — how many, whether any need re-routing, and where they discharge. Stormwater connection matters: a downpipe emptying next to the house is a foundation problem waiting to happen.
Corners, stop-ends and mitres. Internal and external corners need custom fittings and take time. A complex roofline costs more per metre than a simple rectangle.
Brackets to standard. Australian plumbing standards specify bracket spacing — commonly 1,200mm centres. Under-bracketed guttering sags and holds water.
Removal and disposal of the old system — typically $200 to $500.
Scaffolding or roof access equipment where required — $1,500 to $3,000 on a two-storey.
Gutter guard or mesh, if you want it. Worth considering in bushfire-prone areas, where ember protection is a genuine safety measure rather than just a leaf-management convenience.
If a re-roof is on the horizon, replacing guttering at the same time is materially cheaper — the access equipment is already up and the trade is already on site. Doing them separately means paying for setup twice.
Frequently asked questions
How much does gutter replacement cost in Australia?
Roughly $45 to $120 per lineal metre installed for Colorbond, the most common choice. A standard single-storey home carries 50 to 70 metres, putting full replacement at $2,200 to $5,800, with typical projects landing near $3,800 including downpipes. Two-storey homes add 20 to 50% for access.
What's the most common unexpected cost?
Rotten fascia boards behind the old guttering. You can't see them until the gutter comes off, and you can't fix new guttering to rotten timber. Replacement runs $50 to $120 per metre. Ask your contractor to inspect the fascia before quoting, not during the job.
How long do gutters last in Australia?
Quality Colorbond commonly gives 20 years or more inland. Near the coast that can drop to 10 to 15 years because salt air accelerates corrosion. If you're close to the water, ask about marine-grade product and budget for earlier replacement.
Should I repair or replace?
Isolated faults — a rusted joint, a sagging bracket, one leaking corner — are worth repairing at $200 to $600. Widespread rust along the gutter base, multiple leaks, or gutters pulling away from the fascia mean replacement, because repairs on a failing system just chase the problem along the run.
Is PVC guttering worth it?
Rarely in Australia. It's the cheapest option at $30 to $45 per metre, but it degrades and warps under sustained UV and heat. The saving disappears the first time you replace it early.
