• Kiln dried and untreated timber is a significant concern if monolithic cladding develops leak issues, due to the lower levels of moisture content required to initiate decay and the accelerated rate of deterioration to the timber framing once decay has been established.
  • Damage to monolithic cladding is usually through a gradual deterioration over a number of years. Taking into consideration that there are three key elements that are required for decay to be initiated and sustained, Moisture, Temperature and Nutrients (timber) and that it does not rain in Auckland for 365 days of the Year, it is fair to assume that if a property has moisture ingress issues that deterioration will be isolated to the wet months and prolonged wet periods.
  • Treated timber can take years for significant damage to occur as opposed to Untreated or Kiln dried timber which damage can occur in a matter of months, making timber treatment a serious consideration when purchasing monolithic clad properties.
  • The initiation of decay requires higher moisture content than required for continued deterioration once decay has been established. With untreated or Kiln dried timber the moisture content requirements are significantly less than that of timber with some treatment. Generally prolonged moisture content of 30% is required to initiate decay in treated timber as opposed to moisture content of over 20% for untreated Timber.


  Timber Treatment Cost includes:


  • Collecting Samples
  • Analysis of Samples
  • Written Report with Certification

 POA (Price on application)

Specialist Inspections have an arrangement with a testing laboratory to have timber filings analysed to determine if the timber has any treatment.Results take approx 5 working days.


Sample collecting process: 


Timber filings are taken from the bottom plate of an external wall in at least two opposing locations. This requires two holes per level to be drilled through the skirting boards into the bottom plate. The hole size is smaller than a ten cent piece that is drilled into the bottom plate of the framing. Where possible Specialist Inspections will take samples from inside wardrobes or cupboards on external walls.


Note: Written permission is required from the owner of the property for Specialist Inspections to samples for anaylising.
