How Much Does Gutter Replacement Cost in Melbourne? (2026)

“How much to replace my gutters?” is one of the most common calls we get. Fair question — but the honest answer is “it depends,” and anyone who quotes you a flat number over the phone without seeing the place is guessing.

Here’s what actually moves the price, so you can read a quote properly instead of just chasing the lowest one.

What drives the cost

• How much gutter there is. Sounds obvious, but the length of run is the biggest single factor. A small unit is a different world to a big double-fronted period home.
• Single or double storey. Height means more setup, more safety gear, sometimes a scissor lift or scaffold. That’s labour and hire cost.
• Eaves gutter vs box gutter. A standard eaves gutter is straightforward. A box gutter — the concealed kind that runs behind a parapet — is a bigger, code-driven job (more on that below).
• Downpipes and where they discharge. New downpipes, rainheads and tying it all back into stormwater properly all add up.
• Fascia condition. If the timber behind the gutter is rotten, that has to be sorted first or the new gutter’s hanging off nothing.
• Access and the profile/colour. Tight side setbacks, two-storey rears, and premium profiles or specific Colorbond colours (Monument, Surfmist, Woodland Grey and the like) all factor in.

Box gutters are their own thing

If you’ve got a box gutter, this is where the real money — and the real risk — sits. A lot of box gutters around Melbourne were built before the current plumbing code (AS/NZS 3500.3) and simply can’t handle a modern downpour. They overflow back into the ceiling.

A proper box-gutter rebuild isn’t just swapping the metal. It means widening the sole, raising the sides, fitting an overflow (a Dam Buster sump and rainhead), replacing the outlets and re-flashing the lot so it’s compliant. Costs more than a patch — but a patch on a failed box gutter is money you’ll spend twice.

Why the cheapest quote often isn’t

The gap between a cheap gutter quote and a proper one is usually in the stuff you can’t see from the street: the fall (so water actually runs to the downpipe), the overflow provision, the fixings, and whether the fascia was dealt with. Cut those corners and the gutter looks fine on day one and fails in the first big storm. We back-cost our jobs, so I can tell you our pricing sits where it needs to for the work to last — not the cheapest, not gouging.

What a good gutter quote should include

• The profile and Colorbond colour, in writing
• Number of downpipes and where they discharge
• Whether fascia repair is included or extra
• For box gutters: the overflow/compliance work spelled out
• That it’s done by licensed roof plumbers, fully insured
