25 Sep How to Protect Your Timber Floors from Water Damage
Protecting Timber Floors from Water Damage
Timber is a classic and durable material that makes for excellent flooring in any home. Its natural warmth and beauty make it a popular choice, but it does have some limitations — and water is its number one enemy.
You may not realise it, but seemingly harmless activities involving water — such as mopping with excess water, small spills, wet shoes after rain, or even humid indoor air — can gradually wear down your timber floors. Over time, this can lead to swelling, staining, mould growth, and permanent structural damage.
Top Tips for Protecting Timber Floors
The FloorVenue team has rounded up our best professional tips to help protect your wooden floors from moisture and water damage. With the right habits and care, your timber floors can stay beautiful for decades.
1. Use Rugs and Mats
This is one of the easiest and most effective ways to prevent water damage. Place rugs or mats in high-risk areas such as the kitchen, dining areas, and bathroom doorways. It’s also smart to use mats in front of appliances like refrigerators, dishwashers, and air conditioners, where leaks are most likely to occur. Choose rugs with breathable backings so moisture does not get trapped underneath, and wash or air them out regularly.
2. Apply a Protective Sealant
Seal your timber flooring with a quality coating to make it resistant to moisture. FloorVenue’s installers always ensure coatings are applied in line with Australian Standard AS 2796, which governs the grading and finishing of timber floors for long-term protection.
Finishes such as polyurethane provide an invisible barrier that prevents timber from absorbing water. Wax can also be used in some cases, but be mindful that certain finishes (like urethane-based products) may react poorly with wax. Always check suitability before application. In general, re-coating every few years will help maintain strong protection. For more on coatings and finishes, explore our detailed guide on choosing timber flooring finishes.
3. Clean Carefully
Cleaning timber floors properly will significantly extend their life. Avoid harsh detergents, chemicals, or strong abrasives, as they may cause staining or strip away protective coatings. Never power wash or steam mop timber floors — stubborn stains should always be treated by a professional. For regular cleaning, use a slightly damp (not wet) mop and always dry the floor immediately. For a step-by-step routine, check our blog on timber floor maintenance.
4. Fix Leaks Quickly
Ongoing leaks from plumbing or appliances can severely damage timber. Fix broken pipes, taps, or seals in the bathroom and kitchen as soon as possible. Ensure appliances with water connections — such as refrigerators, dishwashers, or air conditioners — are inspected and serviced regularly. Even a slow drip can cause irreversible damage if ignored for too long.
5. Control Humidity
Moisture doesn’t only come from spills. Seasonal humidity changes can also cause timber to expand, contract, or warp. Keep your home’s humidity between 40–60% where possible. During wet summers in Sydney, dehumidifiers or air conditioning can help. In winter, avoid running heaters directly over timber floors. Maintaining a stable environment will greatly reduce long-term movement and cupping.
The effects of water damage can be very difficult, and often impossible, to fully repair. That’s why prevention is always more cost-effective than restoration.

Where Not to Install Timber Flooring
While timber floors are versatile, there are some areas in the home where they should not be installed due to high moisture levels. These include:
- Bathrooms
- Kitchens
- Laundries
- Bar areas
- Toilets
- Kitchenettes
For these spaces, consider waterproof alternatives such as hybrid flooring, vinyl plank flooring, or traditional tiles, which are designed to withstand constant exposure to moisture while still offering stylish finishes.
FloorVenue’s professional installers also check that all timber installations comply with Australian Standard AS 1884, which requires no more than 4mm variance over 2 metres in the subfloor. This ensures your new timber flooring remains stable, even in less-than-ideal conditions. If the subfloor needs levelling before installation, our team offers professional subfloor preparation services.
Alternatives for Wet Areas
If you want the warmth of timber but need water resistance, there are excellent alternatives. Hybrid floors combine the beauty of timber-look designs with 100% waterproof SPC or WPC cores, making them perfect for kitchens and apartments. Vinyl planks are also fully waterproof, soft underfoot, and highly affordable. If you prefer a natural stone or ceramic look, tiles remain the gold standard for bathrooms and laundries.
Early Warning Signs of Water Damage
Learning to spot early signs of water damage can save your floors from major repair or replacement. Watch out for:
- Cupping — edges of boards curl upwards
- Crowning — board centres bulge upwards
- Milky or cloudy patches in the finish (trapped moisture)
- Black stains or mould around joints
- Persistent creaking or spongy feel when walking
If you notice these issues, pause wet cleaning immediately and seek professional advice. FloorVenue can assess and recommend the best course of action, whether that means sanding, refinishing, or in severe cases, replacing boards.

Final Thoughts
Timber floors bring timeless elegance and value to any home, but they demand respect when it comes to moisture. By following good habits like using rugs, maintaining sealants, cleaning carefully, controlling humidity, and responding quickly to leaks, you’ll enjoy beautiful floors that last for decades.
For areas where timber isn’t suitable, explore practical alternatives such as hybrid or vinyl plank flooring. And if you’re planning an installation, remember that compliance with AS 2796 and AS 1884 standards is essential for long-term performance.
