How Much A Square Metre?

Square metre (Sqm) rates for any cladding are always dependent on the following factors.


  1. Building complexity
  2. Ease of installation
  3. Site access
  4. Hill site
  5. Wall heights
  6. Number of storeys
  7. Roof design
  8. Raking cuts above roofs
  9. Roof gables
  10. Roof wall and balcony junctions
  11. Number of windows and doors
  12. Scaffolding
  13. Travel costs
  14. Hourly labour rates which vary throughout NZ

All cladding installers take these important factors into account when correctly pricing a job. The price is adjusted in light of the complexity of each specific project.

To quote a cladding price without viewing the plans is foolhardy. The quoted price would be misleading to the building owner.

Manufacturers who quote square metre rates for their claddings generally base their pricing on a single storey simple house with straight walls on a flat section and easy access which gives a false view of the real costs.
Simply said, square metre rates provide only very general indicative pricing which almost always increases when the job is properly estimated following a detailed take off from the plans.
Flashclad prices are comparable and often cheaper than other cladding options especially when factoring in the cost of painting the new cladding and true lifecycle costs such as future re-painting and replacing of sealant.

Fibre Cement and Timber Weatherboards

On completion of Fibre cement or timber weatherboard installation there is the additional cost associated with approximately four weeks of scaffold hire while waiting for the painter to apply the essential weather protection to the cladding. A further extension of the scaffold hire is inevitable in winter when rain and low temperatures delay the completion of the painting.

The erection, hire and removal of Scaffolding are very significant cladding costs. With Flashclad the moment the last board is fitted the scaffold can come down because there is no further work to be done from a cladding perspective.
Re-painting is required approximately every 10 years to maintain the integrity of timber and fibre cement cladding, to meet the NZ Building Code requirements and to avoid nullifying cladding warranties.

The owner is also required to ensure all sealant is diligently inspected and faulty sealant replaced as a maintenance requirement to ensure warranties remain valid and to mitigate the risk of leaks. This is no easy or cheap task, especially if scaffold is required.

The cost of repainting, necessary scaffolding and safety protection is a considerable expense. In order to ensure that these types of claddings continue to perform and prevent moisture ingress the repainting and scaffolding will have to be done at least twice over the following twenty years, adding an extra unavoidable maintenance cost of approximately $40,000 to an average home.



Recoating with a timber stain or similar to maintain the natural look (that provides the main aesthetic appeal of cedar) is required every 2-3 years throughout the life of the cladding.
The sunny north and west elevations may need staining every year according to cedar manufacturers’ instructions.
Recoating is necessary to ensure the integrity of the cladding by mitigating the risk of cupping or warping of the boards so that the cladding continues to meet the NZ Building Code performance and durability requirements and to avoid nullifying cladding warranties.
As for fibre cement and timber weatherboards the cost of recoating, including the cost of scaffolding and site protection is significant. Cedar claddings are often used in more natural bush type settings with sloping sections that can further increase the cost of scaffolding.

Life Cycle Costs

The cost of cladding over its intended life is a very real consideration. Life Cycle Costs can be likened to purchasing a new printer. There is a big price range but inevitably if you decide on a cheap one you will also have to pay a fortune in ink cartridges at regular intervals.
The same is true of cladding. Flashclad powder coated, pre-finished cladding has very low Life Cycle Costs. It does not require or need expensive re-painting or re-scaffolding. Because Flashclad is a sealant free cladding system, there is no ongoing labour costs associated with the NZBC requirement to inspect or replace faulty sealant to ensure weathertightness.

“The most expensive wall claddings are PVC, Fibre-cement and timber weatherboards.”
