Eaves Lining & Fascia Cost Calculator (Australia)

What this calculator estimates

This calculator quotes the all-in installed price for full eaves and fascia replacement on a typical Australian home in 2026 AUD. It separates the bill into the line items real Australian eaves contractors invoice:

• Eaves lining (soffit) — the horizontal under-eave covering, sold per linear metre of eave run.
• Fascia board — the vertical board behind the gutter (or bargeboard at the gable verge), sold per linear metre.
• Strip-off — removal and disposal of existing eaves and fascia.
• Paint or factory finish — on timber requiring field-painting.
• Soffit vent strip — continuous ventilated strip for AS 4859 / NCC J3 attic intake ventilation.
• External corners — pre-formed corner sections (typically 4 on a simple gable, 6 to 10 on hip and complex layouts).

A minimum call-out floor of $380 applies on most Australian installations. Small jobs under 12 linear metres often hit the floor because the EWP or scaffold mobilisation plus crew dominates small-job cost.

How to use it

1. Eaves lining linear metres — total eave run where lining meets the outer wall. Typical 3-bed single-storey: 35 to 50 m. Two-storey: 45 to 70 m.
2. Fascia linear metres — usually equal to eaves run. Add bargeboards if you want gable verges wrapped.
3. Material — vinyl uPVC (cheapest), Colorbond / Zincalume aluminium (most common modern choice), painted hardwood timber, James Hardie fibre-cement HardieSoffit / HardieFlex (bushfire-rated), or composite HPL (Trespa, Weathertex).
4. Building height — single-storey is the baseline. Two-storey adds 15 percent. Three-storey or higher adds 35 percent.
5. Site access — easy (open suburban block), moderate (some landscaping, normal setback), or difficult (power lines, narrow access, scissor lift required).
6. Strip-off — toggle ON for any replacement job.
7. Paint or factory finish — toggle ON for raw timber requiring painting. Vinyl, Colorbond, Hardie, and composite arrive factory-finished.
8. Soffit vent strip — toggle ON to add continuous intake ventilation. Strongly recommended on most NCC J3 / AS 4859 modern roof renewals.
9. External corners — count corners where eaves and fascia turn 90 degrees. Simple hip roof: 4. Complex Federation hip-and-valley: 8 to 12.

Typical 2026 Australian eaves & fascia cost ranges

Add 10 to 20 percent for severe coastal salt-spray sites (Cape York, Geraldton, exposed central QLD coast) requiring marine-grade Colorbond or 316 stainless fasteners.

Cost drivers

Material. Vinyl is the cheapest material at around $9 to $15 per linear metre delivered, but Colorbond aluminium is the workhorse — better UV life, no brittleness, fire-resistant, and only 15 percent more expensive on average. Painted hardwood is mid-priced but adds an ongoing 8- to 12-year paint cycle. James Hardie fibre-cement is bushfire-compliant and more durable than timber, but adds 30 to 50 percent to installed cost because of weight, slower cutting, and AS 4969 silica dust controls. Composite HPL (Trespa, Weathertex) is the most durable and most expensive — 50 to 80 percent over vinyl.

Building height. Single-storey is the baseline. Two-storey adds 15 percent for ladder repositioning and harness setup at every eave run. Three-storey or higher adds 30 to 40 percent because of EWP hire, WHS-mandated fall-protection setup, and the slower pace working at height. Scissor lift hire runs $280 to $420 per day and gets billed through.

Site access. Open suburban blocks are easy. Mature gum-tree canopy over the eave, deck or verandah obstructions, or air-conditioner compressors under the eave are moderate. Overhead 240 V or 11 kV lines within 4 m of the eave require Energex / Endeavour / Western Power de-energisation request or qualified line-clearance crew on standby — that scenario can add 25 to 40 percent.

Strip-off condition. Sound timber being replaced for cosmetics is easy strip-off. Subterranean termite damage in pine framing under the eave is common in QLD, NSW, NT, and WA, and adds carpentry time at $75 to $105 per hour plus mandatory termite barrier reinstatement under AS 3660.1. Pre-1990 asbestos-cement eaves (super-six or fibro) require licensed Class B asbestos abatement under the Work Health and Safety Regulations 2017 — that alone can triple the strip-off line and requires waste manifest to a licensed landfill. Always include a 15 to 25 percent contingency for termite or asbestos discovery on properties over 30 years old.

Bushfire (BAL) compliance. In BAL-29, BAL-40, or BAL-FZ zones (check your local council bushfire-prone overlay), eaves and fascia must be non-combustible. James Hardie or Colorbond is the typical compliant choice, with non-combustible eave vents and steel-blocking around any service penetrations. Compliance is verified during occupancy or insurance renewal — failing BAL compliance can void insurance after a bushfire claim.

When to replace eaves and fascia

Termite or wet-rot evidence. Soft spots, mud tubes on bargeboards, or peeling paint with damp wood underneath demand immediate action. Termite damage in fascia almost always indicates entry into wall framing — book a licensed pest inspector before booking the eaves contractor.

Re-roof timing. Always check eaves and fascia before signing a new Colorbond or tile re-roof contract. The cheapest moment to replace is during the re-roof while the gutters are off and the scissor lift or scaffold is on site. Adding it after the fact often costs 25 to 40 percent more.

Gutter replacement timing. New Colorbond gutters mounted on rotted hardwood fascia will pull loose within 2 to 3 years. Replace fascia at the same time as gutters or beforehand.

Pest entry. Possums, birds, and brushtail possums in particular enter roof spaces through gaps in eaves and rotted fascia corners. Note that some possum species are protected under state wildlife legislation — entry exclusion must follow humane removal protocols.

Storm damage. Cyclones (QLD, WA Top End), severe thunderstorms (SE QLD, SE NSW), and gusts above 100 km/h commonly peel Colorbond or vinyl eaves panels off lower edges. Document with photos within 72 hours for the insurance claim — most policies require notification within 30 days.

Bushfire BAL upgrade. After a regional bushfire event, your local council may re-categorise BAL zones. If your home moves from BAL-12 to BAL-29 or higher, eaves replacement to non-combustible materials may be required before insurance renewal.

What to look for in an Australian contractor

A competent Australian eaves contractor will:

1. Survey on-site with a fascia probe and termite check, not from a photo or aerial estimate.
2. Inspect rafter ends and top plate for rot or termite damage before quoting.
3. Quote line-by-line: eaves material, fascia material, strip-off, vent strip, corners, paint, EWP or scaffold hire.
4. Provide manufacturer specification with BlueScope Colorbond warranty registration (full 15- to 30-year coastal warranty requires registration within 90 days).
5. Carry public liability of at least $10 million and workers’ compensation under the relevant state Workers’ Compensation Act.
6. Hold a state builder’s licence (NSW HIA, VIC VBA, QLD QBCC, WA Building Commission, SA CBS, TAS CBOS, NT BPB, ACT ACTPLA) appropriate to the contract value.
7. Belong to ARC (Australian Roofing Contractors) or Master Builders Australia.
8. Offer a written workmanship warranty of at least 6 years under state domestic building contract law plus the manufacturer’s product warranty.

Red flags: refusal to inspect rafter ends, quotes that exclude EWP or scaffold hire, cash-only requests, and unsolicited door-to-door cold callers offering “today only” pricing after storms.

Diagnostic checklist before quoting

Before signing a contract, walk the perimeter with the contractor and tick:

• Soft spots or sponginess in fascia (probe with a screwdriver — should be firm).
• Termite mud tubes on bargeboards or eaves soffit.
• Paint peeling, blistering, or fading more than 30 percent.
• Visible nail-head rust staining running down fascia.
• Gutter joints leaking or brackets pulled loose.
• Daylight visible from inside the roof space at the eave line.
• Possum, bird, or rodent entry in eaves corners.
• Bare timber exposed where Colorbond or vinyl has detached.
• Pre-1990 fibro / super-six suspicion (test before disturbing).
• BAL bushfire zone re-categorisation since last inspection.
