At a Glance
Door and window carpentry in Perth typically costs $300–$1,900 per job. Most Perth homes have aluminium-framed windows (handled by a glazier, not a carpenter), so carpenter-led window work here is primarily timber frames in older character homes and new solid timber installations. Doors are the more common carpenter job across the board.
What's Included in the Price
- Removal of existing doors or timber windows
- Fitting and hanging new doors or window units into openings
- Adjustment for plumb, level, and square
- Installation of hinges, hardware, and weather seals (external openings)
- Architrave trimming and refitting
- Compliance with NCC energy performance requirements for external units
Hardware (handles, locks, deadbolts) is usually quoted separately. For timber windows, the carpenter handles the frame and sash work; glazing is a separate trade.
What Affects the Cost
- Aluminium vs timber distinction. In Perth, most window replacement is aluminium-framed and handled by window companies, not carpenters. A carpenter is involved when the job is timber window frames (older homes, heritage properties) or when door hanging is the primary scope.
- Number of doors. Single-door jobs carry a minimum callout cost. Replacing 4+ doors at once brings the per-unit rate down.
- Frame condition. Perth's dry heat causes timber frames to shrink and crack over time. Frames in older Fremantle and Cottesloe homes may need replacing alongside the doors.
- Sliding and bi-fold doors. Large sliding doors connecting indoor and outdoor spaces are a Perth favourite. These are bigger installations that require level tracks and structural headers.
- Bushfire zones. Properties in the Perth Hills (Kalamunda, Mundaring, Roleystone) may require BAL-rated doors and windows with fire-rated glazing.
- Internal vs external. External doors need weather sealing, security hardware, and energy compliance. Perth's hot summers and occasional storms make proper sealing important.
Hanging a single internal door in a modern Butler home with a square frame sits toward $300. Replacing the front door, back door, and multiple timber window frames in an older Fremantle cottage with custom joinery and period hardware pushes toward $1,900.
Perth-Specific Considerations
Aluminium window dominance. Perth's post-war building boom used aluminium-framed windows almost exclusively. If you need aluminium window replacement, you are looking at a window company or glazier rather than a carpenter. Carpenters handle timber window frames, which are found in older homes (pre-1960) and in contemporary builds where timber is specified for aesthetic reasons.
Older character homes. Fremantle, Cottesloe, Subiaco, Mount Lawley. These suburbs have period homes with original timber-framed windows and solid timber doors. Restoration or replacement of these elements is carpenter territory. Fremantle's limestone cottages present additional challenges because the masonry surrounds are irregular, requiring careful scribing and fitting.
Large sliding and bi-fold doors. Perth's indoor-outdoor lifestyle and large block sizes drive demand for wide sliding or bi-fold door openings. These installations often require structural headers (lintels) across the opening and precise floor-level work to ensure smooth operation.
Bushfire zones. Perth Hills suburbs including Kalamunda, Mundaring, Darlington, and Roleystone are designated bushfire-prone areas. External doors and windows in these zones must meet BAL (Bushfire Attack Level) requirements, which may mandate specific glazing types and frame materials. This adds to both material cost and compliance complexity.
Heat and timber movement. Perth's hot, dry summers cause timber to shrink, while winter rains cause expansion. Doors that stick in winter and have gaps in summer are a common complaint. A good carpenter allows for seasonal timber movement when fitting doors and windows.
Hiring a Licensed Carpenter in WA
In Western Australia, builder registration is managed by Building and Energy (DEMIRS). Registration is required for work that needs a building permit or is valued over $20,000. For smaller door and window jobs, registration is not mandatory but recommended.
Ask for:
- Builder registration number (if applicable) or ABN and insurance details
- Proof of public liability insurance
- A written quote specifying door/window types, hardware, and frame scope
- Confirmation of BAL requirements if you are in a bushfire zone
Red flags: Cannot provide registration for larger jobs, quotes without inspecting frames, or does not account for seasonal timber movement in Perth's climate.
How We Calculate
Estimates are based on current registered builder and carpenter rates across the Perth metropolitan area, adjusted for local material costs in WA. All prices include GST. Figures cover standard residential door and timber window carpentry. Aluminium windows, structural modifications, and commercial glazing are not included.
