What changes the price of borer treatment
The published price lists above differ mainly on these points, so a quote that names each one is easier to compare:
- Which spaces are treated: ceiling cavity, subfloor, or both; subfloor access is often the deciding factor.
- House size: published prices step up with the number of bedrooms.
- Inspection first: several businesses charge for an inspection or assessment, and some say the fee is credited if treatment goes ahead.
- Damage: treatment does not replace weakened timber; repairs by a builder are a separate cost.
How these figures were collected
Each figure was read on the business's own website on 6 October 2026 and is shown exactly as published: no conversion to a common GST basis and no estimates. Market-wide "typical price" articles were left out because they do not show what a business itself charges. Only businesses that do the work themselves were included. Prices change, so confirm the current price with the business.
