How to Quote Guttering and Fascia Jobs

Why guttering quotes need their own system

Guttering and fascia work is measured in linear metres, priced by profile and material, and affected by access more than most trades. A single-storey quad gutter swap is straightforward. A two-storey heritage half-round replacement with rotten fascia, scaffold, and gutter guard is a different job entirely, and your quote needs to reflect that.

This guide covers the rates, benchmarks, and line items Australian roof plumbers use to quote guttering and fascia jobs in 2026. Every figure comes from current trade pricing, supplier catalogues, and market data across Australian capital cities and regional centres.

Gutter profiles and characteristics

Australian residential guttering uses four main profiles. The profile determines supply cost, flow capacity, and which homes it suits.

Quad 115mm is the workhorse. It handles the vast majority of residential replacement work across tile and metal roofs. Half-round carries a heritage premium but is essential for period homes where council or heritage overlay requires a matching profile. Square-line is growing in new builds where architects want a clean horizontal edge. Box gutters sit between roof planes and carry the highest cost because they require waterproof membrane lining and overflow provisions under AS/NZS 3500.3.

Gutter supply and install costs per metre

These rates cover supply of gutter, brackets, pop rivets, silicone, and installation labour on a single-storey home with standard ladder access. Two-storey scaffold and old gutter removal are separate line items.

Colorbond from BlueScope Lysaght is the default material for Australian residential guttering. The 0.42mm BMT (base metal thickness) is standard for residential; 0.55mm BMT is used for commercial and high-wind areas. Zincalume is the same steel without the paint layer, suitable for concealed applications or budget-conscious jobs where appearance is secondary.

Fascia board costs

Fascia condition determines whether you can install new gutters directly or need to repair or cover the fascia first. Always inspect fascia before finalising a gutter quote. Rotten fascia discovered mid-job costs you time and margin.

Colorbond fascia cover is the most popular option for gutter replacement jobs because it wraps over the existing timber, eliminates future painting, and colour-matches the new gutters. If the underlying timber is structurally sound, covering is faster and cheaper than full replacement. If the timber is rotten or sagging, it must be replaced before the cover goes on.

Full house perimeter fascia renewal on a mid-sized home (50-65 linear metres) runs $4,000 to $15,000 depending on material and access. Quote fascia as a separate line item from guttering so the customer can see each component.

Downpipe costs

Downpipes connect gutters to the stormwater system. Size them to AS/NZS 3500.3 based on your region's rainfall intensity and the roof catchment area draining to each pipe.

Each downpipe drop includes the pipe length, offset bends at the eaves, wall brackets (typically every 1.8 metres), a shoe or adaptor at the base, and connection to the existing stormwater drain. The per-drop price covers all fittings for a standard installation. If the stormwater drain is blocked, broken, or absent, quote the drain connection separately.

Downpipe sizing guide (AS/NZS 3500.3:2025)

These are simplified guidelines. The actual sizing depends on your specific rainfall intensity (from Bureau of Meteorology IFD data for your location), roof pitch, gutter profile capacity, and whether the system includes overflow provisions. Always size to the standard rather than relying on rules of thumb.

Gutter guard costs

Gutter guard is a high-margin add-on that saves the customer ongoing gutter cleaning costs. Always offer it as an optional line item on every gutter replacement quote.

Installing guard at the same time as new gutters saves a second mobilisation and access setup. Price the add-on at the time of quoting so the customer can compare the guard cost against ongoing cleaning fees ($250-$600 per clean, typically twice per year in leafy areas). In bushfire-prone areas rated BAL-12.5 or above, ember guard mesh to AS 3959 may be a compliance requirement rather than an option.

Labour rates and productivity

Productivity benchmarks

Productivity drops with each additional complexity layer: corners, mitre cuts, restricted access, and working at height. A straight 12-metre run of quad on a single storey takes about 40 minutes for a two-person crew. The same run on a two-storey home with scaffold, rotten fascia, and three corners could take two hours.

Access and scaffolding costs

Access is the single biggest variable in guttering quotes. A single-storey home with clear ground access is a ladder job. A two-storey home with garden beds, fences, or tight side access needs scaffold or an elevated work platform.

Always quote scaffolding as a separate line item. Customers understand that working at height costs more, but they expect to see the access cost broken out rather than buried in an inflated per-metre rate. If you own your own scaffold, the cost to the customer should reflect your setup time and transport, not just the hire fee you would otherwise pay.

Old gutter removal and disposal

Any home built before 1990 may have asbestos cement (fibro) gutters or downpipes. The material looks like grey cement with a slightly rough texture. If you suspect asbestos, stop work and get a sample tested before disturbing it. In most states, removing more than 10 square metres of non-friable asbestos requires a Class B licence. Quoting asbestos removal without the right licence exposes you to fines up to $50,000 in some jurisdictions.

Whole-job benchmarks

These benchmarks cover typical residential guttering jobs in Australian metro areas at 2026 rates. Regional areas may run 5-15% lower; remote and high-access jobs run higher.

Worked example: single-storey 3-bed Melbourne gutter replacement

A single-storey three-bedroom brick home in Melbourne's eastern suburbs. The existing 115mm galvanised quad gutters are 25 years old, leaking at multiple joins, and the timber fascia is weathered but structurally sound. The customer wants Colorbond quad gutters in Woodland Grey, Colorbond fascia cover, four new downpipes, and standard aluminium mesh gutter guard. Roof catchment is approximately 160 square metres.

Margin check

Material cost for this job: gutter stock ~$480, fascia cover ~$520, downpipes ~$160, guard mesh ~$530, fittings and consumables ~$310. Total materials approximately $2,000. Labour: two-person crew, estimated 1.5 days at $150/hr blended = $1,800. Total cost base approximately $3,800. Quoted subtotal $7,320 gives a gross margin of approximately 48%, which covers overheads (vehicle, insurance, tools, admin, warranty callbacks) and leaves a healthy net margin in the 25-30% range for an established roof plumber.

The gutter guard adds $1,680 to the job at minimal extra time (about 2.5 hours for 48 metres), making it the highest-margin component on the quote. Always present it as an add-on option.

Regional price variation

Guttering prices vary across Australian cities based on labour costs, material transport, and local competition. Melbourne is used as the baseline.

Darwin runs highest due to transport costs, smaller trade pool, and cyclone-rated fixings. Perth pricing reflects the mining-economy labour premium. Adelaide and Brisbane are competitive markets with strong roof plumber density keeping prices lower. Rural and regional areas typically run 5-15% below capital city rates due to lower overheads, but travel time for remote properties can push individual job costs above metro rates.

Licensing by state and territory

Guttering is classified as roof plumbing work in most Australian states. The licensing requirements vary significantly.

Victoria is the only state that has specifically regulated residential roofing, requiring a registered roof plumber for all work. NSW Fair Trading requires a licence regardless of job value. In WA, the $20,000 threshold means many residential gutter jobs fall below the licensing requirement, but you still need a plumber's licence for the stormwater connection component. Always display your licence number on quotes and marketing material.

Relevant Australian Standards

AS/NZS 3500.3 was updated in 2025 with clearer overflow provisions and increased valley gutter catchment areas (from 20 sqm to 40 sqm). If you are quoting to the standard, confirm you are working from the 2025 edition. The new eaves gutter overflow measures require design for at least 1% Annual Exceedance Probability (AEP), which is a more demanding design criterion than the previous edition.

8 common quoting mistakes

1. Not measuring the actual run length. House plans show wall lengths, not gutter runs. Eaves overhang adds 300-600mm per end. A plan that says 12 metres of wall can be 13 metres of gutter. Always measure the gutter line, not the wall.
2. Ignoring fascia condition. Rotten fascia discovered mid-job means stopping work, sourcing fascia board, and doing unquoted carpentry. Check fascia before you quote gutters. Prod suspect sections with a screwdriver.
3. Forgetting fall. Eaves gutters need a minimum fall of 1:500 (2mm per metre) to the downpipe outlet. On long runs, this can mean the gutter sits noticeably lower at one end. If the fascia is level and the gutter needs fall, discuss it with the customer before installation.
4. Underquoting two-storey access. Scaffold adds $500 to $3,000 to a job. If you absorb it into your per-metre rate, you either lose margin or price yourself out of single-storey work. Quote scaffold as a separate line item.
5. Not checking for asbestos. Pre-1990 homes may have asbestos cement gutters. Removing asbestos without testing and a licence is illegal and dangerous. A $150 lab test protects you from a $50,000 fine.
6. Under-sizing downpipes. A 75mm downpipe on a large roof catchment will overflow in moderate rain. Size to AS/NZS 3500.3 using your region's rainfall intensity, not by matching whatever was there before. The previous installer may have got it wrong.
7. Quoting gutter guard without checking profile compatibility. Guard mesh designed for quad profiles does not fit half-round gutters. Ember guard for one brand may not fit another. Confirm the guard product is compatible with the gutter profile before quoting a combined price.
8. Not allowing for stormwater connection. New downpipes need to connect to the stormwater system. If the old drain is blocked, broken, or missing, that is additional scope. Inspect the stormwater connection point during your site visit and note its condition on the quote.

Presenting your quote

A guttering quote that converts includes these items:

1. Customer and site details - name, address, date, quote number, validity period (typically 30 days).
2. Scope of work summary - one or two sentences describing the job in plain language ("Replace all existing gutters, fascia cover, and downpipes on the single-storey home at 14 Elm Street").
3. Line items with quantities and unit rates - gutter per metre, fascia per metre, downpipes per drop, guard per metre, removal, disposal, scaffold. Customers trust itemised quotes more than lump sums.
4. Materials specification - Colorbond colour name, profile, gauge (0.42mm or 0.55mm BMT), guard mesh type. This protects you if the customer disputes what was installed.
5. Gutter guard as an optional add-on - show the price with and without guard so the customer can see the value.
6. Exclusions - state clearly what is not included: stormwater pipe upgrades, soffit replacement, painting, tree removal, asbestos removal (if not in scope), electrical work for downlights near eaves.
7. Access assumptions - "price based on standard ladder access" or "includes partial scaffold to rear elevation." If access conditions change, the price may change.
8. Licence and insurance - your roof plumbing licence number, public liability policy number, and WorkCover details. This is a legal requirement in most states and builds trust.
9. Payment terms - deposit amount (if any), progress payments for large jobs, and final payment on completion. Most residential gutter jobs are paid on completion.
10. Warranty - state the workmanship warranty (typically 5-10 years) and the manufacturer's material warranty (Colorbond carries a 20-year BlueScope warranty when installed by a licensed tradesperson).
