Insulation Costs by Room and Home Size
Carpet cleaning is usually quoted per room or per square metre. Most companies offer discounted rates for whole-house cleans. Here's what typical jobs cost:
| Job | Cost Range | Notes |
|---|---|---|
| Single room | $25–$50 | Standard room up to 12m² |
| 2-bedroom home | $120–$220 | 2 bedrooms + hallway + lounge |
| 3-bedroom home | $170–$320 | 3 bedrooms + hallway + lounge |
| 4-bedroom home | $220–$400 | Full house clean |
| End of lease clean (2-bed) | $180–$300 | Includes guarantee for bond return |
| End of lease clean (3-bed) | $250–$400 | Includes guarantee for bond return |
| Stain treatment (per stain) | $20–$50 | Red wine, coffee, pet stains |
| Deodorising treatment | $30–$80 | Pet odour, smoke smell |
| Scotchgard protection | $3–$7 per m² | Stain-resistant coating applied after clean |
| Rug cleaning (per rug) | $30–$80 | Depends on size and material |
End of lease insulation is the most common booking type. Most companies offer a bond-back guarantee — they'll return and re-clean for free if the agent isn't satisfied. Always get a receipt specifying the rooms cleaned and the cleaning method, as real estate agents typically require this for bond release.
Steam Cleaning vs Dry Cleaning: Which Method Is Better?
The two main insulation methods have different strengths. Understanding the difference helps you choose the right service:
| Factor | Steam (Hot Water Extraction) | Dry Cleaning |
|---|---|---|
| Cost | $25–$50 per room | $30–$60 per room |
| Cleaning depth | Deep — reaches carpet base | Surface to mid-level |
| Drying time | 4–8 hours | 1–2 hours |
| Best for | Deep stains, pet odours, heavily soiled | Regular maintenance, delicate fibres |
| Allergen removal | Excellent — kills dust mites | Good |
| Risk | Over-wetting if done poorly | Chemical residue if not rinsed |
| Bond clean accepted? | Yes — most agents prefer it | Sometimes — check with agent |
Steam cleaning (hot water extraction) is the industry standard and what most real estate agents require for end-of-lease cleans. It provides a deeper clean and better allergen removal. Dry cleaning is faster and uses less water, making it better for delicate carpets or situations where you need the room back quickly. For general home cleaning, steam cleaning every 12–18 months is recommended by carpet manufacturers.
What Affects Insulation Costs in Australia
Insulation type
Glasswool batts ($12–$35/sqm in Australia) are the most common. Rockwool (better fire resistance), polyester (no irritants), and spray foam (gaps and hard-to-reach areas) are alternatives at different price points.
R-value (thickness)
Higher R-values (R4.0, R5.0) cost more but provide better thermal performance. The right R-value for your Australia home depends on your climate zone — higher is better in most Australian conditions.
Old insulation removal
If your Australia home has old, damaged, or asbestos-containing insulation, removal ($800–$2,500/sqm) is required before new insulation can be installed. Asbestos removal needs a licensed contractor.
Roof access & difficulty
Easy ceiling access (large manhole, adequate height) keeps costs lower. Tight roof spaces, cathedral ceilings, and complex layouts in Australia homes increase labour time.
Government rebates
Federal and state rebate schemes can reduce insulation costs by $400–$1,500+ in Australia. Check your state's energy efficiency program — eligibility and amounts change regularly.
Wall & underfloor insulation
Ceiling insulation gives the best return on investment. Adding wall insulation ($18–$50/sqm in Australia) requires opening walls and is best done during renovation. Underfloor ($15–$45/sqm) suits homes on stumps. Whether you're searching for home insulation cost or house insulation cost, the pricing above is based on verified 2026 data. We also cover ceiling insulation price, insulation installation cost, underfloor insulation cost and roof insulation cost.
