Gutter Replacement Cost Calculator & Price Guide
Use our gutter replacement cost calculator to estimate how much new gutters may cost based on material, length and building height. For Australian homes, a gutter replacement cost estimator can help benchmark jobs from around $40 per lm for Zincalume up to $65 per lm for Colorbond in a premium or designer colour, before any height adjustment and subject to a $1,500 minimum job charge. If you want a quick starting point, this gutter cost calculator uses the same live pricing logic as the guide below, with all prices in AUD.

Gutter Replacement Price Breakdown
Typical job based on 60 lm. Prices are supply-and-install midpoints — actual quotes will vary.
| Type | Cost per lm | Typical 60 lm job |
|---|---|---|
| Zincalume | $40 | $2,400 |
| Colorbond (standard colour) | $60 | $3,600 |
| Colorbond (premium / designer colour) | $65 | $3,900 |
What Affects Gutter Replacement Cost?
- Gutter material: Material is the biggest driver of price per lineal metre. Zincalume is priced at $40/lm, Colorbond in a standard colour is $60/lm, and Colorbond in a premium or designer colour is $65/lm.
- Total gutter length: This calculator is based on gutter length in lineal metres, so longer runs increase the total cost directly. A 60 lm job will cost more than a smaller replacement because the per-lm rate is applied across the full measured length.
- Building height: Height affects access and installation complexity, which changes the final cost. Single-storey homes use a ×1 multiplier, while double-storey homes use a ×1.25 multiplier on the lineal metre cost.
- Minimum job charge: If the calculated total comes in below the minimum service threshold, the minimum job charge applies instead. On this pricing setup, any result under $1,500 AUD is lifted to a $1,500 minimum.
Gutter Replacement Cost - Frequently Asked Questions
The gutter replacement cost calculator multiplies your gutter length by the selected material rate, then applies the building height multiplier if needed. Rates are $40/lm for Zincalume, $60/lm for standard Colorbond, and $65/lm for premium or designer Colorbond, with double-storey homes using a ×1.25 multiplier. The displayed estimate range is then shown at ±15% around the midpoint, and a $1,500 AUD minimum job charge applies if the maths fall below that.
For a typical 60 lm single-storey job, the midpoint estimate is $2,400 AUD for Zincalume, $3,600 AUD for standard Colorbond, and $3,900 AUD for premium or designer Colorbond. For a double-storey home at 60 lm, those midpoints become $3,000 AUD, $4,500 AUD, and $4,875 AUD respectively. The displayed range is calculated at ±15% around each midpoint.
The lowest listed material rate in the gutter cost calculator is Zincalume at $40 per lineal metre. On a 60 lm single-storey home, that gives a midpoint of $2,400 AUD before the estimate range is applied. If a smaller job calculates below $1,500 AUD, the minimum job charge means the estimate starts at $1,500 AUD instead.
The highest listed material rate is Colorbond in a premium or designer colour at $65 per lineal metre. On a 60 lm single-storey home, that works out to a midpoint of $3,900 AUD, while a 60 lm double-storey job comes to $4,875 AUD after the ×1.25 height multiplier. The calculator then displays an estimate range of ±15% around those figures.
Yes, building height changes the estimate because double-storey homes use a ×1.25 multiplier on the lineal cost. For example, 60 lm of standard Colorbond is $3,600 AUD on a single-storey home and $4,500 AUD on a double-storey home. The same multiplier applies to Zincalume and premium or designer Colorbond pricing as well.
The calculator includes a $1,500 AUD minimum job charge so very small jobs do not price below the service minimum. For example, if your gutter length and selected material produce a result under $1,500 AUD, the displayed estimate will be adjusted up to that minimum. This keeps the online estimate aligned with the live pricing rules.
