Renovating an older home brings its own set of challenges, especially when you’re trying to balance original character with modern performance. If you’re living in a pre-1980s Perth home, chances are your existing timber doors are showing their age. Paint’s peeling, frames are warping, and you’re probably watching your energy bills climb every summer.
The good news? Today’s door technology has come a long way. You can upgrade to products that perform brilliantly in Perth’s climate whilst still honouring your home’s architectural heritage. Let’s go through your options.
Why aluminium doors work so well for Perth renovations
When we talk to home-owners about the best doors for renovating an older home, quality aluminium doors consistently tops the list.
Perth’s Mediterranean climate is tough on building materials. High UV levels accelerate paint failure on timber. Coastal suburbs deal with salt air corroding untreated steel. Powder-coated aluminium sidesteps both problems. The finish typically carries a 25-year warranty and requires virtually no maintenance beyond an occasional wash-down.
The NCC 2022 energy provisions have tightened whole-of-home energy requirements across Australia. Modern double-glazed aluminium doors with thermally broken frames can achieve U-values around 2.3–2.6 W/m²K, compared with around 5–6 W/m²K for older single-glazed timber systems, potentially reducing heat loss through glazing by around 40–60% depending on the product and installation.
Aluminium sliding and stacker doors
These are our most popular choice for rear extensions and alfresco connections. Slim frames maximise glass area, flooding older homes with natural light whilst creating seamless indoor-outdoor flow.
Stacker doors work particularly well when you’re opening up a 1950s brick home’s kitchen to a new outdoor entertaining area. The panels slide and stack neatly to one side, giving you a wall of open space on summer evenings. They’re also BAL-29 capable with toughened glazing, which matters if you’re in Perth’s outer suburbs or the Hills.
We’ve helped hundreds of Perth owners modernise their post-war bungalows with sliding doors that honour the original proportions whilst slashing cooling costs.
Aluminium French doors
If your home has Federation or inter-war character, French doors can provide heritage styling with modern performance. Muntin bar kits replicate traditional divided-light patterns, while powder-coat finishes now include deep heritage greens and charcoals that suit period façades.
Heritage guidelines in the City of Fremantle are generally more flexible for side and rear elevations, where aluminium joinery may be acceptable if the frames replicate original proportions and do not affect the street façade. This has opened up options for owners of workers’ cottages in suburbs like Leederville and Mount Lawley who want improved thermal performance without compromising street appeal.
When timber still makes sense
Solid hardwood doors remain the authentic choice for federation and Californian bungalow front entrances. If you’re restoring a heritage-listed property or want absolute period accuracy on your main façade, timber delivers visual warmth and traditional detailing that’s hard to match.
Modern timber doors can be fitted with double-glazed inserts for improved energy performance. The trade-off? You’re committing to ongoing maintenance. Perth’s UV and coastal air mean you’ll be repainting or re-staining every few years to prevent deterioration.
For replacement doors for older homes where the front entrance sees full sun exposure, we often suggest keeping timber for the street-facing door whilst upgrading side and rear doors to aluminium. You get heritage authenticity where it counts most, plus practical performance where you need it.
Composite doors: the middle ground
Fibreglass-skinned composite doors are becoming more common in Perth renovation projects. They typically feature insulated cores that provide strong thermal performance (often around R-2 or higher depending on the product) and resist warping, splitting and rot far better than solid timber. Many designs are available with realistic timber-grain textures or smooth painted finishes, giving homeowners flexibility in both traditional and contemporary styles.
One of the key advantages is durability in coastal conditions. Unlike timber, fibreglass skins are highly resistant to moisture and temperature changes, making them well suited to environments where UV exposure and sea air can accelerate wear on natural materials.
uPVC doors: thermal champions with caveats
If energy efficiency is your top priority, uPVC doors offer excellent thermal performance. Modern systems with double glazing can achieve U-values around 1.8 W/m²K or lower, thanks to their multi-chambered frame design that helps reduce heat transfer. The material also performs well in coastal environments because it resists corrosion and moisture.
The challenge for older homes is aesthetics. uPVC frames are typically thicker than aluminium, which can look heavier on heritage façades. For that reason, they are more commonly used in contemporary extensions or modern renovations rather than period-style replacements.
Steel-look aluminium: trending for good reason
One of the most requested modern doors for older homes right now is the steel-look aluminium pivot or French door. It gives you that sought-after ‘Crittall’ aesthetic with fine black frames and large glass panels, but uses corrosion-resistant aluminium instead of steel.
This style works beautifully in mid-century homes or when you’re adding a contemporary extension to a heritage property. The slim sightlines suit both period and modern architecture, and you’re getting all the durability advantages of aluminium door installation in Perth.
Making your choice: what matters most
The best doors for home renovation come down to weighing several factors against your specific situation:
Thermal performance matters if you’re trying to meet 7-Star energy requirements or want lower cooling bills. Double-glazed aluminium or uPVC will deliver the biggest improvements over original single-glazed timber.
Maintenance is worth considering honestly. If you love the ritual of caring for timber, that’s fine. But if you’d rather spend weekends at the beach than repainting doors, aluminium or composite makes more sense.
Heritage aesthetics can usually be achieved with modern materials. Slim-frame aluminium with colonial bars and period colours satisfies most heritage guidelines whilst performing far better than the originals.
Cost varies widely, but aluminium typically sits in the mid-range. Solid timber and high-end composites cost more. uPVC can be economical but may need wider installation tolerances.
The HIA Renovations Round-Up 2025 notes that WA recorded the fastest renovation growth nationally at 5.6%, driven largely by energy-efficiency upgrades. That tells us Perth home-owners are prioritising performance improvements, and doors are a key part of that equation.
Your next step
Renovating an older Perth home gives you the chance to blend character with comfort. Modern door technology means you don’t have to choose between period charm and practical performance.
Whether you’re restoring a federation cottage in Subiaco or opening up a mid-century brick home in Applecross, there’s a door solution that fits your style, budget and Perth’s demanding climate. The key is matching the right product to your specific needs.
