Treat-Right Warranty


Through the use of next generation TANALITH wood preservative together with the quality timbers we use, their careful preparation for treatment and the use of incising technology where applicable, we offer Treat-Right Performance Warranties against decay and insect attack on our fencing timbers.
Fencing Range
  • For our fencing timbers, we can offer a 15 Year Treat-Right Warranty on our incised Spruce and Redwood square sawn fencing timbers.
  • We offer a 30 Year Treat-Right Warranty on our range of Redwood fencing round timbers.


Covered is the cost of re-supply by Hales Sawmills, or the re-supply by Hales Sawmills (at our option), of a component that is proven to have failed as a result of fungal decay or insect attack. It does not cover the costs of removal or reinstatement of such components or consequential costs or loss due to failure of the component.

The term ‘fungal decay’ as used in the warranty refers to wood destroying fungi that feed on and degenerate the wood cell walls. It excludes staining and mould fungi associated with the weathering of wood.

The term ‘insect attack’ refers to attack by wood digesting insects that destroy the timber structure.

The term ‘failed’ refers to damage caused by insects and/or fungi to such an extent that the component is no longer fit for purpose.

This does not affect the statutory rights of consumers, or exclude or restrict the liability of Hales Sawmills for death or personal injury caused by negligence, or for fraudulent misrepresentation.
