The exact cost will depend on the size of your home. But here are some estimates for a typical home (120m2).
- Ceiling insulation: $1600 to $4000
- Under-floor insulation: $2900 to $3500
- Wall insulation: $2850 to $7000
The best way to determine the exact price for your home is to get a quote.
If you don’t have the budget to address all of these areas at once, insulating your ceiling should be the number one priority.
