Estimate an illustrative price range for replacing or adding external wall cladding on a house, by wall area and cladding type.
This estimator gives a rough range for re-cladding the walls of a house. Choose a cladding type, enter the net wall area (wall length × height, minus large windows and doors) and the fixed costs.
How it works. Low = area × low rate + fixed costs; high = area × high rate + fixed costs. The rates fill in from the option you choose and you can overwrite them.
Worked example (illustrative). A single-storey house with 48 m of external wall at 2.7 m high has 129.6 m² gross. Subtract about 25 m² of windows and doors and you have roughly 105 m². For fibre cement weatherboard at $100–$180 per m² plus $5,000 fixed: low = 105 × 100 + 5,000 = $15,500; high = 105 × 180 + 5,000 = $23,900.
Limits. Rates are illustrative, include GST and are not quotes. They exclude asbestos removal (old fibro walls in pre-1990 homes may contain asbestos and must be tested first), structural repairs to rotten studs, new windows, and bushfire-rated (BAL) products, which can cost more. Cladding on apartment buildings is a different market with its own fire rules: see the combustible cladding guide.
