Timber floors are one of the most durable flooring options in any Brisbane home. But even the toughest hardwood floors don’t last forever without maintenance. Over time, daily wear, foot traffic, furniture movement, and Brisbane’s subtropical climate all take their toll on your floor’s finish.
Knowing when your floors need professional sanding helps you act before minor wear becomes major damage. Here are the signs to watch for.
1. The Finish Is Worn Through in High-Traffic Areas
Look at the areas of your home that get the most foot traffic — hallways, the path between the kitchen and living room, the area in front of the kitchen sink. If you can see patches of bare timber where the protective finish has worn away, your floor needs sanding.
Once the finish is gone, the bare timber is exposed to moisture, dirt, and wear. It will absorb spills, stain easily, and deteriorate much faster than protected timber. The longer you leave it, the more the timber itself gets damaged.
2. Visible Scratches and Scuff Marks
Light surface scratches on the finish coat are normal and usually cosmetic. But when scratches are deep enough to expose bare timber, or when their accumulation makes the floor look dull and tired, sanding is the solution. Common culprits include furniture legs without felt pads, pet claws, tracked-in grit, and high heels.
3. Water Stains and Discolouration
Dark spots or rings on your timber floor often indicate water damage — from plant pots, pet bowls, or spills not cleaned up quickly. If the stains have penetrated into the timber itself, sanding is needed to remove the stained wood. Greying near windows caused by UV exposure is also fixed by sanding back to fresh timber.
4. The Floor Feels Rough or Splintery
A well-finished timber floor should feel smooth underfoot. If your floor has started to feel rough or splintery — especially in areas exposed to moisture or heavy traffic — the protective finish has failed and the timber is beginning to deteriorate. Don’t ignore a splintery floor, especially in a home with young children.
5. Boards Are Cupping or Crowning
Cupping occurs when the edges of a floorboard are higher than the centre. Crowning is the opposite. Both are caused by moisture imbalance — common in Brisbane’s humid climate. If boards have permanently deformed, sanding can level the surface, but only after the underlying moisture issue has been fixed.
6. The Finish Is Peeling or Flaking
If your floor finish is peeling, bubbling, or flaking off in sheets, the coating has lost adhesion. This can happen due to poor surface preparation, subfloor moisture, an incompatible finish applied over an existing coating, or the finish reaching the end of its lifespan. Peeling finish can’t be fixed with a recoat — the floor must be sanded back to bare timber.
7. It’s Been 10+ Years Since the Last Sand
Even well-maintained floors typically need re-sanding every 7 to 15 years. If you can’t remember when your floors were last sanded — or if you know it’s been a decade or more — have a professional assess their condition. Proactive maintenance is always cheaper and less disruptive than emergency restoration.
What Happens If You Don’t Sand When You Should?
- Surface wear becomes timber damage — once the finish is gone, the timber itself wears, stains, and absorbs moisture
- More material needs to be removed — deeper damage means more aggressive sanding, reducing future sanding potential
- Repairs increase — boards that could have been saved may need replacing
- Cost increases — all of the above means a bigger, more expensive project
Frequently Asked Questions
Can I just recoat instead of sanding?
If the existing finish is still intact across most of the floor and only looks dull or lightly scratched, a recoat may be enough. But if the finish is worn through, peeling, or if you have deep stains, sanding is necessary.
How do I check if my finish is worn through?
Drip a small amount of water onto a high-traffic area. If it beads up, the finish is intact. If it soaks in and darkens the wood, the finish is gone and the timber is unprotected.
Is sanding disruptive? Do I need to move out?
You don’t usually need to move out, but the rooms being sanded will be out of use for two to three days. Modern dust extraction equipment significantly reduces mess.
