What changes the price on your job
The ranges above are the starting point. These five factors are what move a quote up or down within (or sometimes outside) those bands.
- Property age - pre-1995 likely no barrier (or expired); 1995+ usually has physical/chemical barrier installed.
- Soil type - sandy soils need re-treat sooner than clay; coastal needs more frequent inspection.
- Vegetation proximity - gum trees within 50m elevate risk.
- Construction type - slab-on-ground vs stumps changes barrier strategy.
- Sub-floor access - limited access homes need extra inspection time.
Red flags - what to watch for in quotes
We see these patterns every week from operators we'd never recommend. If a quote you've received contains one of these, ask before signing.
- 'Free termite inspection' that turns into a $4,800 barrier quote on the day - get an independent inspection first.
- Quotes using off-label / unregistered chemicals - illegal and uninsurable.
- Cheap-end barriers without 8-year warranty - usually wrong product concentration.
- Operators not AEPMA-registered - no chemistry training accountability.
- Skipped sub-floor inspection - 60% of active infestations are first visible in sub-floor.
How to get an accurate quote in 5 minutes

- Whether you've had an inspection before (and the report if so).
- Any visible mud trails, frass, or sagging skirting.

- Sub-floor access (slab vs stumps).
