What Affects Chemical Barrier Cost?
1. Perimeter Length
More perimeter = more chemical + more labour.
2. Soil Type
Rocky soil = slower trenching
Clay = manageable
Sand = requires stabilisation
3. Concrete Drilling Requirements
Concrete paths increase drilling time and chemical volume.
4. Footing Depth
Deeper foundations require more product.
5. Termite Pressure in Your Suburb
High-risk suburbs require stronger protection.
Why a Cheap Barrier Is a Red Flag
Cheap quotes usually indicate shortcuts:
❌ Under-dosing chemical
❌ Untrained installers
❌ No drilling under concrete
❌ No warranty
❌ Low-quality products
A cheap barrier is the most expensive decision a homeowner can make.

| Professional Barrier | $2,200 – $5,000 |
