Repairing Damaged Floors After Termite Damage: A Perth Homeowner's Complete Guide

What to do when white ants have eaten through your floors — and how to get them looking better than ever

A practical guide for homeowners in Perth, Morley, Belmont, Bassendean, Cockburn, Wellard, Bentley and surrounding suburbs

There's a particular sinking feeling that comes with discovering termite damage in your home. You might notice a soft spot underfoot in the hallway. A floorboard that gives way slightly when you step on it. A skirting board that crumbles when you push a screwdriver into it. Or maybe a building inspector has just delivered the news you were dreading — white ants have been silently chewing through your subfloor and you didn't even know they were there.

If this sounds familiar, you're far from alone. Perth sits in one of the highest termite risk zones in Australia, and our warm, dry climate combined with sandy soils creates ideal conditions for subterranean termites to thrive. Suburbs with older housing stock — particularly Bassendean, Belmont, Morley, Bayswater, Bentley and surrounding areas — are especially vulnerable, with many homes built on timber subfloors and stumps that termites find irresistible.

The good news? Once the termites have been treated and eradicated by a licensed pest controller, your floors can absolutely be repaired and restored. In many cases, homeowners end up with a better floor than they had before the damage was discovered.

At Spencer Flooring, we've helped dozens of Perth families navigate the process of repairing and replacing termite-damaged flooring — from assessing what's salvageable, to recommending the right replacement product, to completing a full professional installation that protects your home for years to come.

Here's everything you need to know.

How Termites Damage Flooring in Perth Homes

Before we talk about repairs, it helps to understand what you're actually dealing with. Termites don't just eat the surface of your floorboards — they work from the inside out, often leaving the outer layer of timber intact while hollowing out the structural core underneath.

This is why termite damage is so dangerous. By the time you notice visible signs — sagging floors, hollow-sounding boards, bubbling or blistering in timber surfaces — the damage below is usually far more extensive than what you can see.

Common signs of termite damage to flooring:

• Floorboards that feel soft, spongy or bouncy underfoot
• Hollow sounds when you tap on timber floors or skirting boards
• Visible tunnelling or "mud tubes" along subfloor bearers and joists
• Buckling, warping or sagging in specific sections of flooring
• Crumbling or disintegrating timber when pressure is applied
• Fine sawdust-like debris (frass) around skirting boards or under the house

What termites target in Perth homes:

In Perth's older suburbs — think Bassendean, Bayswater, Morley, Embleton, Belmont and Bentley — many homes were built with timber subfloor structures including bearers, joists and stumps. These structural timbers are prime targets for subterranean termites, and once they've compromised the subfloor structure, the flooring on top is effectively sitting on a weakened or failing base.

Even homes on concrete slabs aren't immune. Termites can travel through expansion joints, plumbing penetrations and cracks in the slab to reach timber door frames, skirting boards and the flooring itself.

Step 1: Get the Termites Treated First

This should go without saying, but it's critical: do not begin any flooring repair or replacement work until the termite infestation has been fully treated and cleared by a licensed pest controller.

There is absolutely no point installing beautiful new floors on top of an active termite problem. You'll just be giving them a fresh meal.

A licensed pest management professional will:

• Identify the species of termite and the extent of the infestation
• Treat the active colony using baiting systems or chemical barriers
• Assess structural damage and recommend whether an engineer's report is needed
• Issue a clearance or treatment certificate

In Western Australia, termite treatment and management must be carried out by a licensed pest management technician. We always recommend using a company that holds the appropriate licences under WA's Health (Miscellaneous Provisions) Act 1911 and associated regulations.

Once you've received clearance that the infestation is dealt with and appropriate barriers or monitoring systems are in place, it's time to turn your attention to the floors.

Step 2: Assess the Extent of Floor Damage

Not all termite damage requires a complete floor replacement. In some cases, damage is localised to a specific section of the home and can be repaired without pulling everything up. In other cases — particularly where structural subfloor timbers have been compromised — a more comprehensive approach is needed.

What we look for during a termite damage flooring assessment:

When we visit a Perth home to assess termite-damaged flooring, here's what our team checks:

• Surface flooring condition — Are the floorboards themselves damaged, or just the subfloor beneath them?
• Subfloor structural integrity — Are bearers and joists sound, or do they need replacement by a builder or carpenter?
• Extent of damage spread — Is the damage confined to one room or has it spread throughout the home?
• Moisture levels — Termite damage is often accompanied by moisture issues that need addressing before new flooring goes down
• Slab or timber subfloor — The subfloor type determines what replacement flooring options are suitable and what preparation is required

When you need a builder involved:

If the structural subfloor timbers (bearers and joists) are significantly damaged, you may need a licensed builder or structural carpenter to replace those elements before any new flooring can be installed. This is common in older homes across Bassendean, Bayswater, Morley and the inner eastern suburbs where original subfloor timbers may be 40, 50 or even 60+ years old.

Spencer Flooring works alongside trusted local builders and carpenters in the Perth area to coordinate this process seamlessly. We can recommend reliable tradespeople if you don't already have someone in mind.

When flooring-only repair is sufficient:

If the structural subfloor is sound and only the surface flooring has been damaged — or if only a section of flooring is affected — we can often complete the repair as a standalone flooring job. This might involve:

• Removing and replacing damaged sections of timber floorboards
• Installing new flooring over a structurally sound subfloor
• Patching specific areas and blending with existing floors where possible

Step 3: Decide Whether to Repair or Replace

This is one of the biggest decisions you'll face after termite damage, and the right answer depends on several factors.

When repairing (patching) makes sense:

• Damage is confined to a small, localised area
• The existing flooring is in good condition elsewhere and worth preserving
• You have matching timber species and profile available
• The floor can be sanded and refinished to blend the repair seamlessly

When full replacement is the better option:

• Damage is widespread across multiple rooms
• The existing flooring is old, worn or already due for replacement
• Matching the existing product is impossible or impractical
• You want to upgrade to a more termite-resistant or low-maintenance flooring option
• The subfloor has been repaired or replaced and you're starting fresh

The honest truth about patching timber floors:

Patching termite-damaged timber floors can work well in some situations, but it's not always as simple as it sounds. Finding matching timber species, profile dimensions and age-appropriate colouring can be challenging — especially with older Perth homes that may have original jarrah or karri floorboards that are no longer readily available in the same grade.

If a seamless match isn't achievable, a full sand and refinish of the entire floor after patching can help blend everything together. However, if more than 30–40% of the floor is damaged, a complete replacement often delivers a better result for a similar overall cost.

Step 4: Choose the Right Replacement Flooring

If you're replacing termite-damaged floors — whether one room or the entire home — this is actually an opportunity to upgrade to a product that's better suited to your lifestyle, your home and Perth's climate.

Here are the options we most commonly recommend for Perth homeowners replacing floors after termite damage:

Hybrid SPC Flooring — The Smart Choice After Termite Damage

Hybrid flooring is our number one recommendation for homeowners replacing termite-damaged floors in Perth. Here's why:

• Termites can't eat it — hybrid flooring is made from stone polymer composite (SPC), not organic material. Termites have zero interest in it.
• 100% waterproof — if moisture was a contributing factor to your termite issue, hybrid flooring won't be affected by residual dampness
• Dimensionally stable in Perth's climate — won't expand, contract or warp with our hot summers
• Quick installation — click-lock system means your home is back to normal faster
• No sanding or finishing required — ready to walk on immediately after installation
• Works over both concrete and timber subfloors — versatile for all Perth home types

For homes in Cockburn, Wellard, Baldivis and newer southern suburbs built on concrete slabs, hybrid is particularly well-suited because it floats over the slab without any adhesive and includes a built-in underlay.

Perth pricing: Hybrid flooring supply and installation typically ranges from $55–$110 per square metre depending on the product quality and subfloor preparation required.

Engineered Timber Flooring — For Those Who Want Real Wood

If you love the look and feel of real timber but want something more stable and forgiving than solid hardwood, engineered timber flooring is an excellent choice after termite repairs.

Engineered timber features a genuine hardwood veneer on top (usually 2–4mm thick) bonded to a multi-layered plywood or HDF core. This construction provides:

• The authentic warmth and beauty of real timber
• Greater dimensional stability than solid hardwood
• Ability to be sanded and refinished (1–3 times depending on veneer thickness)
• Compatibility with glue-down, float or nail-down installation methods

Important note: While termites can still potentially target engineered timber flooring (the core contains wood products), a properly installed termite management system combined with regular inspections significantly reduces this risk. We always recommend maintaining your termite barrier and annual inspections regardless of what flooring product you choose.

Perth pricing: Engineered timber supply and installation typically ranges from $80–$160 per square metre.

Vinyl Plank Flooring — Affordable, Practical and Termite-Proof

Luxury vinyl plank (LVP) flooring offers a budget-friendly alternative that's completely immune to termite attack. Like hybrid, it contains no organic material that termites find appetising.

LVP is particularly popular for:

• Investment and rental properties where budget and durability are priorities
• Homes where water exposure is a concern (bathrooms, kitchens, laundries)
• Homeowners who want a quick, cost-effective solution after a stressful termite ordeal

Perth pricing: Vinyl plank supply and installation typically ranges from $40–$85 per square metre.

Step 5: Subfloor Preparation After Termite Damage

This is where the quality of your flooring installation truly matters. After termite damage — and especially after structural repairs — the subfloor needs careful assessment and preparation before any new flooring goes down.

What subfloor preparation involves after termite work:

• Checking all repaired or replaced subfloor timbers are level and secure — new joists or bearers must be properly aligned and fixed
• Levelling any high or low spots — termite repairs can leave uneven surfaces that need grinding or filling
• Moisture testing — particularly important after termite treatment where chemical or water-based products have been applied to the subfloor area
• Installing appropriate moisture barriers where required — especially over concrete slabs or in areas where moisture contributed to the original termite problem
• Removing any remaining damaged material — old adhesive, degraded timber particles, or debris from the treatment process

Proper subfloor preparation is always important, but it's especially critical after termite damage. The last thing you want is to install beautiful new floors on a subfloor that hasn't been properly assessed and prepared.

At Spencer Flooring, subfloor inspection and preparation is included as a standard part of every installation. We never skip this step — it's the foundation of a floor that lasts.

Step 6: Protecting Your New Floors from Future Termite Damage

Once your new floors are installed and looking fantastic, the final piece of the puzzle is making sure you never have to go through this process again.

Ongoing termite prevention for Perth homeowners:

• Maintain your termite management system — whether that's a chemical barrier, baiting stations, or a physical barrier, it needs regular monitoring and maintenance
• Book annual termite inspections — Australian Standard AS 3660.2 recommends annual inspections for all homes in termite-prone areas. Perth falls firmly in this category.
• Address moisture issues — fix leaking taps, ensure drainage flows away from the home, and maintain proper ventilation in subfloor areas
• Keep gardens and mulch away from the perimeter — termites use garden beds as highways into your home
• Don't store timber against the house — firewood, old fence palings, and timber offcuts stacked against external walls are an open invitation

Flooring choices that reduce termite risk:

While no building material makes your home completely termite-proof (they'll still target structural timbers, door frames and other elements), choosing a non-organic flooring product like hybrid or vinyl plank means your floor surface itself will never be a target. This gives you one less thing to worry about.

How Long Does the Whole Process Take?

From termite treatment to new floors underfoot, here's a realistic timeline for most Perth homes:

Total from treatment to completed floors: Typically 6–14 weeks depending on the extent of structural work required.

We understand this process can feel overwhelming — especially when you're already dealing with the stress and cost of termite treatment. Our goal at Spencer Flooring is to make the flooring repair stage as simple, transparent and stress-free as possible.

What Does Termite Damage Flooring Repair Cost in Perth?

Every termite damage situation is different, so it's difficult to give a one-size-fits-all price. However, here are the key cost components you should be aware of:

Typical cost breakdown:

• Structural subfloor repairs (builder/carpenter) — $1,500–$10,000+ depending on extent of damage
• Removal and disposal of damaged flooring — $5–$15/m²
• Subfloor preparation — $10–$30/m² depending on work required
• New flooring supply and installation — $40–$160/m² depending on product chosen

Insurance considerations:

It's worth noting that most standard home and contents insurance policies in Western Australia do not cover termite damage. Termite damage is almost universally classified as a maintenance issue and excluded from coverage. This means the cost of repairs typically falls on the homeowner.

However, if you have specific timber pest coverage or a newer policy with enhanced inclusions, it's always worth checking with your insurer. Some builders' warranty insurance may also provide coverage in certain circumstances for newer homes.

This is another reason we always recommend regular termite inspections — prevention is far cheaper than cure.
