How the calculator works

From kitchen table to fixed quote.

Built on real Canterbury install jobs — not a generic ballpark. Same numbers our estimators use.

01

Tell us about your home

House type, age, bedrooms and storeys. Just enough for us to size the job accurately without bombarding you with questions.

02

Pick your areas

Walls, ceiling, underfloor or acoustic. Toggle one or stack them — bundling unlocks an automatic discount in the side panel.

03

See a live price range

We use real Canterbury install pricing for 2024-25, not a generic calculator. Quick mode estimates from your profile; detailed mode lets you map rooms.

04

Lock it in with a free quote

Drop your details and we'll confirm the exact figure on-site. Your estimate is included automatically — nothing to retype.
