Jarrah is a rich, deep red to red-brown Western Australian hardwood that darkens and warms further with age. It's a hard, dense timber, roughly comparable to Blackbutt, harder than European Oak and generally a step softer than Spotted Gum. It suits traditional and character homes, warm interiors and restorations, and it's often found in older Sydney houses where an existing floor needs sanding, repairing or matching.
If you're researching Jarrah flooring in Sydney, whether that's a new floor or bringing an original one back to life, this page covers how Jarrah looks, how it wears, what to expect from finishes and when another species may suit better. Design Timber Flooring is owner-operated by Jimmy, who brings samples to your home and gives you a free on-site quote once he has seen the rooms and the subfloor.
What Jarrah is
Jarrah (Eucalyptus marginata) is a eucalypt that grows in the south-west of Western Australia. It has been used for flooring, joinery and construction in Australia for a very long time, and many older homes across the country, including some in Sydney, were built with Jarrah floors or Jarrah features.
Today it's supplied in smaller volumes than eastern species such as Blackbutt or Spotted Gum, and much of what is available comes from regrowth forests or recycled timber. That affects which grades and widths are on hand at any given time.
Colour and grain
Jarrah is one of the darkest and richest-coloured Australian hardwoods used for floors.
- Colour. Freshly milled Jarrah ranges from salmon pink and light red through to deep red-brown. It darkens noticeably over the first months and years, settling into a deep, warm burgundy or brown-red.
- Grain. Usually fairly straight but sometimes interlocked or wavy, with an even, moderately coarse texture. Some boards show fiddleback figure.
- Natural features. Gum veins, small gum pockets and occasional pin holes appear, particularly in feature grades. Select grades keep these to a minimum.
Because Jarrah darkens so much, a sample cut recently will look lighter than the finished floor will after some time in the sun. Ask to see aged boards as well as fresh ones, and view them in your own light. Grade names vary between suppliers, so compare real boards rather than labels.
How hard-wearing is Jarrah?
Jarrah is a hard, dense hardwood. In plain terms:
- It's broadly similar to Blackbutt, sometimes rated a touch softer.
- It's clearly harder than European Oak, so it resists dents from everyday use better than most engineered oak.
- It's generally softer than Spotted Gum and Ironbark, which are among the hardest species used for floors.
That puts Jarrah comfortably in the range for family living areas, hallways and dining rooms. As with any timber, grit, claws, heels and dragged furniture can still mark it. The coating, entry mats, felt pads and regular sweeping make as much difference to day-to-day wear as the species itself.
Solid or engineered Jarrah
Jarrah is most commonly supplied as solid hardwood in traditional strip widths, installed over joists, battens or a suitable sheet subfloor and sanded and coated on-site. Recycled Jarrah boards are also available from some suppliers and can suit restorations or a more aged look.
Engineered Jarrah, with a Jarrah wear layer over a stable core, is offered by some suppliers but in a narrower range than for paler species. Availability of grades, widths and engineered versions varies by supplier and is confirmed at quote. Our solid hardwood flooring service explains how solid boards are fixed and finished.
Finishes and how Jarrah takes stain
Jarrah's colour is its main attraction, so it's almost always finished clear rather than stained.
- Water-based polyurethane shows Jarrah's natural red-brown tones with less added warmth, in matte or satin sheens.
- Oil-based polyurethane deepens and ambers the colour further, giving a very rich, traditional look.
- Hard-wax oil gives a soft, low-sheen finish that suits restorations and character homes. It needs a different care routine from polyurethane.
Staining Jarrah lighter isn't realistic, and darker stains add little over its natural colour. Because it's dense and oily in places, stain can also take unevenly. If you want a pale, grey or whitewashed floor, a lighter species such as Blackbutt or European Oak is usually a better starting point.
Where Jarrah suits, and where it doesn't
Good fits:
- Federation, Victorian and interwar homes where a deep, traditional floor sits naturally with period details.
- Restorations and extensions to older homes with original Jarrah boards.
- Warm, rich interiors with timber joinery, darker furniture or heritage palettes.
- Living, dining and hallway areas where its hardness helps with everyday traffic.
Think carefully about:
- Small or dim rooms, where a very dark floor can make the space feel smaller.
- Bright, coastal or Scandinavian-style schemes, which usually suit paler species better.
- Homes with light-coloured pets, as dark floors show dust and hair more readily.
Bathrooms and laundries are generally not suitable for timber floors. Kitchens can work with sensible care and prompt clean-up of spills.
Restoring and matching older Jarrah floors
Many Jarrah floors in older Sydney homes have spent years under carpet, lino or layers of tired coating. Often the boards underneath are still sound and can be sanded back and refinished. The result can look very different from new Jarrah, because decades of ageing give original boards a deeper, more settled colour.
Common restoration work includes:
- Sanding and refinishing the whole floor to remove old coatings, stains and wear.
- Replacing damaged boards with matching Jarrah, ideally recycled boards of the same width and profile.
- Patching areas where walls, fireplaces or heating vents have been removed.
- Extending the floor into a new room or extension.
New Jarrah will usually look lighter and pinker than aged boards at first and darken over time, so matching is about board width, profile and species first, with colour settling in later. Our floorboard replacement service and guide to matching existing hardwood floorboards explain how this is approached. Jimmy will confirm on site whether boards are actually Jarrah, since other red-toned species were also used in older homes.
Sydney's climate and movement
Sydney's humid summers and drier winters mean timber floors take on and give up moisture through the year. Jarrah is generally regarded as fairly stable once properly seasoned and acclimatised, but it will still show small seasonal gaps in drier months and tighten up in humid weather.
Older homes often have subfloor ventilation or moisture issues that affect the floor more than the species does. Before restoring or installing Jarrah, Jimmy checks for cupping, damp, poor ventilation and failed fixings, and allows for expansion around the edges of new floors.
Sanding and refinishing Jarrah
A solid Jarrah floor can usually be sanded and refinished many times, provided enough timber remains above the tongue. Its density means sanding takes care and the right abrasives, and gum veins and the darker colour make poor sanding technique more visible, so machine control matters.
Sanding exposes fresher timber, so a newly sanded Jarrah floor will often look lighter at first and deepen again over the following months. If only the coating is worn, a recoat can be enough. Our sanding and polishing service covers how the work is done.
Jarrah compared with other species
| Species | Typical colour | Grain character | Relative hardness |
|---|---|---|---|
| Jarrah | Pink-red to deep red-brown, darkens with age | Fairly straight, sometimes wavy | Hard |
| Sydney Blue Gum | Pink to red-brown | Fairly straight, open texture | Similar |
| Brushbox | Pink-brown to reddish brown | Fine, even texture | Similar |
| Spotted Gum | Pale grey-brown to chocolate | Wavy, strong character | Harder |
Jarrah or Sydney Blue Gum? Both give a warm, red-toned floor. Jarrah usually ends up deeper and darker, while Sydney Blue Gum stays closer to pink and red-brown and is grown closer to home.
Jarrah or Brushbox? Brushbox is softer in tone with a finer, more even texture, while Jarrah is richer and more dramatic in colour.
Frequently asked questions
Is Jarrah good for flooring?
Yes. Jarrah is a hard, dense hardwood with a long history in Australian homes. It handles everyday traffic well and its rich colour suits traditional and warm interiors. Whether it's right for you depends mainly on whether you want a deep red-brown floor.
Does Jarrah get darker over time?
Yes, noticeably. Freshly milled Jarrah can look quite pink or light red, then darkens towards a deep red-brown with light and age. Oil-based finishes add further warmth, while water-based coatings show the natural tone more closely.
Can old Jarrah floorboards be sanded and polished?
Usually, yes. Original Jarrah under carpet or old coatings is often still sound and can be sanded back and refinished. Jimmy checks board thickness, fixings and previous repairs first, because boards that have been sanded many times may have limited timber left above the tongue.
Can new Jarrah be matched to an existing floor?
It can be matched in species, width and profile, and recycled Jarrah is often the closest option. New boards will usually look lighter at first and darken over time. Exact colour matches can't be guaranteed, but sanding and finishing the whole floor together helps the old and new areas blend.
Can Jarrah be stained a lighter colour?
Not realistically. Jarrah's natural colour is too deep for light stains, and dark stains add little. If you want a pale, grey or whitewashed floor, a lighter species such as Blackbutt or European Oak is a better starting point.
Is Jarrah harder than Blackbutt?
They're broadly similar, with Jarrah sometimes rated slightly softer. Both are well suited to living areas and hallways. Spotted Gum and Ironbark are generally harder than either.
