What moves the price
- Water category. The category has a big effect on price: contaminated water needs more protective work, decontamination and disposal.
- How bad the damage is. More rooms affected and more drying or rebuilding work needed pushes the total up, independently of category.
- How long the water sat before drying started. The longer water soaks into materials, the more needs replacing rather than drying.
- Mould. If mould has already set in, the same cost guide publishes a separate figure for removing it, below.

Frequently asked questions
How much does water damage restoration cost in Australia?
Indicative Australian ranges run from about $1,000 to $20,000 depending on severity and water category, with many household jobs landing around $2,500 to $4,000. Select your category above for a narrower range.
What is a water category, and why does it change the price?
Category 1 is clean water, Category 2 is greywater, and Category 3 is black water. The category has a big effect on price because more contaminated water needs more protective work, decontamination and disposal. A restorer confirms which category applies once they assess the property.
Is this estimator a quote?
No. It gives an indicative range from one published cost guide, not a quote. Only a licensed restoration company, after assessing your property, can give you an accurate price.
