Upgrading your internal doors is one of the most effective ways to modernise an older Perth home. But with so many profiles, materials, and internal cores available, how do you choose the right fit for your living spaces?
In many older suburbs like Armadale and Port Kennedy, homes built throughout the 1980s and 1990s still feature lightweight, dated hollow-core flush doors. Swapping these out for heavier, modern profiles instantly updates the home’s feel and dramatically improves acoustic insulation between your high-traffic living areas.
Our approach: The right internal door style isn’t just about selecting a beautiful design. It’s about matching the door’s weight, material, and hinge capacity to the specific demands of Western Australian homes—particularly when dealing with evaporative cooling draughts, shifting humidity, and coastal salt air.

Characterised by a flat centre panel and simple square edges, Shaker doors provide a clean, structured look that never goes out of fashion. They are incredibly popular in coastal homes around Fremantle and Mandurah, pairing perfectly with modern Hamptons, country, or contemporary interior architecture.
A plain flush door doesn’t have to look cheap. When specified as a heavy, solid-core door and painted in a premium low-sheen finish, a simple flush profile looks highly architectural. It also blocks noise significantly better than cheaper alternatives. Wondering about the structural and acoustic differences? Read our deep dive into solid core vs hollow core internal doors.
Creating separation without losing natural light is a common request in large, open-plan Perth homes. Glazed timber French doors are the traditional, elegant solution for closing off a theatre room or a formal front lounge while keeping the property bright and welcoming.
If you don’t have the wall cavity required for a traditional pocket sliding door but need to preserve walkway space, an exposed track sliding barn door is an excellent retrofit option. They work beautifully for master en-suites, large pantries, or separating a hallway.

The standard advice from volume home builders is simply to use hollow-core flush doors for every bedroom and hallway to save on weight and hardware costs. But in real Perth living conditions, we strongly recommend upgrading main living areas and theatre rooms to at least a semi-solid or solid core.
Yes, a hollow door might cost around $50 less per leaf, but the lack of acoustic insulation guarantees that noise from the kitchen or living room transfers straight into the bedrooms. Furthermore, lightweight hollow doors are highly susceptible to rattling loudly when the afternoon sea breeze pushes through the house, or when evaporative air conditioning creates internal pressure changes across rooms.
Timber and modern composite doors will absorb ambient moisture from the air. In coastal suburbs south of Perth, relative humidity combined with winter rain can cause doors to swell by several millimetres across their width. This is the primary reason why your wooden door might stick and jam in winter.
An experienced local carpenter will allow for a precise 2mm to 3mm clearance gap during the door installation process to accommodate this natural seasonal movement, stopping structural binding before it ever happens.
Budgeting for a whole-house door replacement depends largely on the profile chosen and the core type. Here is an indicative pricing comparison for the door panels themselves (keep in mind this excludes hardware and local labour for the cost to hang the door):
| Door Style & Core | Indicative Cost Range (Per Leaf) | Best Used For |
|---|---|---|
| Flush Panel (Hollow Core) | $45 – $80 | Linen presses, pantries, budget rentals |
| Flush Panel (Solid Core) | $140 – $220 | Bedrooms, home offices, theatre rooms |
| Shaker Style (Semi-Solid) | $180 – $350 | Main living areas, structural upgrades |
| Glazed French Doors (Pair) | $400 – $850+ | Hallway separation, grand entries |
For a standard 4-bedroom home, swapping out 8 to 10 standard interior doors typically requires 1 to 2 days of qualified labour depending on the condition of the existing jambs. If your old timber jambs are twisted or drastically out of plumb, correctly hanging heavy solid doors requires careful manual planing and adjustment.
Whether you need a single set of French doors installed correctly or an entirely modernised full-house package, professional installation is the key to correct clearances, stable hinges, and smooth latching.
