What this calculator estimates

This calculator quotes the all-in replacement price for a residential gutter and downpipe system in 2026 Australian dollars, including GST at 10%. Replacement always includes tear-out, fascia inspection, and almost always drip flashing replacement.

  • Tear-out — labour and tip fees to remove the existing gutters and downpipes. Always included.
  • Fascia repair — new fascia board material and labour where the existing timber has rotted from chronic overflow. The condition selector estimates 0%, 15%, or 40% of the run.
  • Drip flashing / apron flashing — new flashing where the old material is bent, rusted, or attached to the old gutter system.
  • Gutter material — per-metre cost of new Colorbond, Zincalume, aluminium, copper, or zinc gutters in your chosen profile (Quad, D-line, half-round, OG, fascia-bracket).
  • Downpipes — material cost based on quantity (rectangular 75×50 or round 90 mm standard) and run length.
  • Accessories — brackets at 1,200 mm centres per AS 3500.3, sealant, end caps, internal/external angles, leaf-buster guards.
  • Install labour — crew hours at the regional rate, with multipliers for profile complexity, building height, and access.
  • Leaf guards — micro-mesh, ember mesh (BAL-rated), or hood add-on per metre.
  • Permit / certification — most replacements don’t require council approval, but bushfire-prone properties (BAL-12.5+) require non-combustible gutter and ember mesh per AS 3959.

A minimum job floor of $1,080 applies to most Australian replacements — the higher floor versus first-fit reflects mobilisation cost of tear-out and tip disposal.

How to use it

  1. Measure linear length in metres. Sum every eave where guttering runs. A 14-square home is typically 50–58 metres; a two-storey home with verandahs runs 65–85 metres.
  2. Count corners and angles. Each angle adds 30 minutes and a $9–$18 fitting. Most homes have 4–8 angles.
  3. Pick the new profile and material. Colorbond Quad is the Australian residential default. D-line is the modern flat-front profile. Half-round and OG match Federation and Edwardian heritage homes.
  4. Set the size. 115 mm Quad is the post-1990s default. Bump to 150 mm Quad or 125 mm half-round for steep pitches, large catchment areas, or high-rainfall zones (FNQ, Top End, NSW north coast).
  5. Specify downpipes. AS 3500.3 sizing: one 75×50 downpipe per 50 m² of catchment in 1-in-20 ARI rainfall zones, or one per 30 m² in 1-in-100 ARI zones (use Bureau of Meteorology IFD data for your postcode).
  6. Set fascia condition honestly. “Sound” assumes recent inspection confirmed no rot. “Partial” (15% replaced) is the most common condition on a 15-to-25-year-old system. “Extensive” (40% replaced) is typical when the existing gutters have been overflowing for years.
  7. Toggle drip-flashing replacement. Default is on — most replacements swap drip flashing concurrently.
  8. Set storey count and access. Two-storey, scaffolded jobs, and tight side-access properties add 15–25% to labour.

Zinc-titanium VMZINC$125 – $190$7,500 – $11,400

Pricing assumes a two-storey home, 5 downpipes, partial fascia repair, drip flashing replacement, and standard daytime labour. Single-storey deduct 8–10%. Three-storey or full scaffold add 20–25%. Extensive fascia rot adds another $500–$1,400. BAL-29+ ember mesh adds $14–$22 per metre.

Cost drivers

Fascia repair extent. Biggest variable. Sound fascia means $0 added. Partial rot (15%) typically adds $250–$700. Extensive rot (40%) adds $850–$2,100 — at which point you should also be asking your contractor about eaves linings and roof-edge sarking.

Coastal proximity. Within 1 km of breaking surf, Colorbond Ultra (marine-grade) is mandatory for warranty validity. The premium is $4–$7 per metre. Within 200 m of breaking surf, stainless steel or copper is the only sensible choice — Colorbond perforates within 8–15 years.

BAL rating. Bushfire-prone properties (BAL-12.5+) require non-combustible gutters per AS 3959. Standard Colorbond meets this. BAL-29 and above also require ember mesh in gutters at 2 mm aperture, adding $14–$22 per metre. BAL-FZ (Flame Zone) requires steel gutter material throughout — no aluminium.

Profile complexity. Quad is the standard. D-line and half-round add 8–15%. OG and fascia-bracket profiles add 18–25%. Box gutters (parapet roofs) require zinc or stainless and a Hydraulic Engineer’s certificate per AS 3500.3 — add 50–80%.

Storey height and access. A two-storey roof typically takes 10% longer than single-storey. Three-storey or full scaffold add 25%. Tight side-access blocks (common in Sydney inner-west and Melbourne inner-north) add another 10–15%.

Tear-out and tip disposal. Old galvanised steel gutters are heavy and add 15–25 minutes per 6-metre length. Tip fees run $80–$140 per cubic metre at most metro Resource Recovery Centres.

Per-locale code and standards

Australian gutter replacement should be designed and installed to:

  • AS 3500.3:2021 — plumbing and drainage, stormwater drainage. Section 3.6 covers gutter and downpipe sizing for rainfall intensity.
  • AS 2179.1:2014 — specification for rainwater goods, accessories and fasteners.
  • AS 1397 — continuous hot-dip metallic-coated steel sheet and strip (Zincalume substrate).
  • AS 2050:2018 — installation of roof tiles (relevant to drip-flashing detail at the eave).
  • AS 3959:2018 — construction of buildings in bushfire-prone areas. Mandates non-combustible gutters at BAL-12.5 and above; ember mesh at BAL-29 and above.
  • NCC Volume Two Part 3.5 — roof drainage requirements.
  • WHS Regulation 79 — high-risk work licence required for working at heights.

Listed heritage properties require Heritage Council or local heritage overlay consent before changing material or profile — check with your local council’s heritage advisor.

Repair vs full replacement decision matrix

Replace the whole system when:

  • Multiple leaks across more than 30% of joints
  • Visible rust through (Zincalume) or paint failure (Colorbond) across multiple sections
  • Overflow damage has rotted fascia in more than two rafter bays
  • The system is over 20 years old (Colorbond) or 15 years old (Zincalume in coastal areas)

Repair (not replace) when:

  • Damage is localised to one or two joints
  • Brackets are sound and fascia is dry
  • The Colorbond colour is still in the current range and matches the rest of the run

Avoiding scams and overcharging

After significant storm events (particularly summer hailstorms in SE Queensland and NSW), itinerant “storm chaser” gutter contractors door-knock affected suburbs. Red flags:

  • Unsolicited “I noticed your gutters” doorstep approaches in the wake of a storm
  • Pressure to sign before you’ve reviewed a written quote
  • No state contractor licence number on the proposal (ABN alone is not enough)
  • Cash-only or no-GST offers (legitimate Australian contractors charge 10% GST)
  • “Lifetime warranty” without specifying transferability and company longevity

Insist on a written estimate with material specification (Colorbond colour code, Zincalume gauge), bracket spacing, downpipe count and run length, fascia repair line item with per-metre pricing, and a written workmanship warranty (5 years is industry standard for ARC and HIA members).

Frequently asked questions

How much does gutter replacement cost in Australia in 2026?
Most Australian homeowners pay $2,200 to $5,800 to replace gutters in 2026, with a typical project landing around $3,800 for 55–60 metres of Colorbond Quad on a two-storey home with six downpipes, partial fascia repair, drip flashing replacement, and moderate access. Replacement runs 35–55% more than first-fit installation because of tear-out time, tip fees, and the high probability of fascia or eaves damage discovered after the old gutters come down. Premium copper or stainless systems on a heritage Federation home can reach $9,000–$16,000+. Source: 2026 hipages and Master Builders Australia data plus ARC member quotes.
Why is gutter replacement more expensive than a first-time install?
Three reasons. First, tear-out and tip disposal add 4–6 hours of labour and $60–$120 in tip fees. Second, replacement projects routinely uncover fascia and eaves rot — 15–40% of the run typically needs repair before new gutters can mount, adding $350–$1,800. Third, drip flashing, valley irons, and starter brackets are usually replaced concurrently because they're fixed to the old system. Budget 1.4× to 1.6× a first-fit number for an equivalent property.
Should I just repair instead of replace?
Repair when damage is localised — one or two leaking joints, a few broken brackets, or a single dropped run after a storm. Replace the whole system when more than 30% of joints leak, the gutters sag noticeably between brackets, you see rust through on Zincalume or paint failure on Colorbond across multiple sections, fascia damage extends beyond two rafter bays, or the system is over 20 years old. Patchwork repairs on a tired system rarely pay off — most homeowners replace within 3–5 years anyway.
What's included in a typical Australian gutter replacement?
A full replacement bid should include: tear-out and tip disposal of existing gutters and downpipes, inspection and replacement of fascia boards and eaves linings where rotted (typically billed per metre), new Colorbond, Zincalume, or aluminium gutters in your specified profile (Quad, D-line, half-round, OG), new downpipes and shoes, brackets at 1,200 mm centres per AS 3500.3, end caps and external/internal angles, new drip flashing or apron flashing where applicable, sealant at all joints, splash blocks or rainwater tank tie-ins, and clean-up. GST at 10% applies. Always insist on a written line-item proposal — not a single lump sum — and confirm the contractor's licence number with the relevant state regulator (NSW Fair Trading, VBA Victoria, QBCC Queensland, CBOS Tasmania).
How long does gutter replacement take?
A typical residential job (55–65 metres, 4–6 downpipes, two-storey, partial fascia repair) takes a 2-person crew 1–2 days. Day one: tear-out, fascia inspection and repair, drip flashing replacement. Day two: install new gutters, hang downpipes, sealant cure, clean-up. Single-storey homes with sound fascia complete in one long day. Three-storey homes with full scaffold or extensive fascia rot run 3–4 days. SafeWork harness or rail systems are mandatory for working at heights — confirm your contractor has a current SWMS and high-risk work licence.
Does home insurance cover gutter replacement?
Home and contents insurance covers gutter replacement when damage results from a covered event — storm (typically wind speeds over 90 km/h), hail, falling tree, vehicle impact. Wear-and-tear, age-related corrosion, blockage-induced fascia rot are excluded. Document storm damage with photos within 48 hours, notify the insurer within the policy reporting window (usually 30 days), and request an ARC member's report. ICA (Insurance Council of Australia) standards require licensed assessor inspection for claims over $5,000. Storm-damage claims are scrutinised — review the policy's storm definition with the assessor.
Should I replace the fascia at the same time?
Yes when the fascia shows rot, water staining, or soft spots when probed with an awl. Replacing the fascia separately later is twice as expensive because the new gutters have to come back off. Standard practice: tear out the old gutters, probe every metre of fascia, replace every section softer than the surrounding wood. Painted timber fascia at $14–$22 per metre installed; aluminium fascia at $18–$32 per metre installed for a 40+ year service life. The aluminium premium pays back over the next gutter cycle and eliminates repaint cycles in coastal high-UV environments.
Should I upsize when I replace?
Consider it if your old gutters overflowed during heavy rain, your roof catchment exceeds 80 m² per downpipe, you have valleys feeding the run, your roof pitch is above 22.5° (steep pitches deliver concentrated flow), or you're in a high-rainfall zone (FNQ, Top End, Wet Tropics). Going from 115 mm Quad to 150 mm Quad adds about 22% to material cost but doubles capacity. AS 3500.3 Table 3.6.5 has the official sizing tables based on rainfall intensity for your postcode. The retrofit window is now — making the change later requires another tear-out.
What's the difference between Colorbond and Zincalume gutters?
Zincalume is uncoated aluminium-zinc-magnesium alloy steel — silvery-grey finish, 30+ year service life in non-coastal areas, $8–$12 cheaper per metre than Colorbond. Colorbond is the same substrate with a baked-on polymer paint finish in 22 standard colours, lasts 30–50 years, carries a manufacturer's warranty against perforation. Within 1 km of breaking surf, both step down to a marine-grade specification (Colorbond Ultra). For most non-coastal Australian homes, Colorbond is the residential standard and the cost premium is worth the colour match to roof and fascia.
