Pricing guide
Costs are driven by how easy the underfloor space is to access, whether existing insulation must be removed, and the type and R‑value of insulation chosen. Call‑out fees, the regional labour rate and any after‑hours attendance typically increase the overall charge, while homeowner‑supplied materials usually reduce the materials allowance.
Floor access and type
Work on easily accessible suspended timber floors is generally quicker, while tight or obstructed underfloors increase labour time.
Removal and disposal needs
Removing and bagging existing insulation adds handling time and may attract separate disposal work unless included in the selected scope.
Insulation type and R‑value
Standard batts or loose‑fill are common, but higher R‑value or specialist products usually raise material allowances and installation complexity.
Area size and crew required
Hours are based on a single installer baseline and typically scale up to a crew for larger or multi‑room areas.
Call‑out fee and timing
A call‑out fee and the regional labour rate apply, and after‑hours or emergency attendance typically increases the effective hourly charge.
