Performance Warranty Conditions

Warranty Conditions

Performance and Claims under the Warranty

The Jon Walker Timber Products Gold Label range of high performance timber posts (described below as “fence posts”) designed for Use Class 4 ground contact applications, when installed and used in accordance with the appropriate standards, have a 25 year performance warranty against failure of the timber from fungal decay or insect attack.

The warranty is limited to the cost of re-supply of the affected fence post by Jon Walker Timber Products that is proven to have failed as a result of fungal decay or insect attack within 25 years of supply to a Maximum Claim Value*. The Maximum Claim Value means a percentage of the Jon Walker Timber Products price of the fence post on the date of the failure. The percentage is calculated as the total length of the warranty period (25 years) less the period of satisfactory use.

By way of example. If the fence post failed after 12⁄2 years of satisfactory use then the Maximum Claim Value would be 50% of the Jon Walker Timber Products price at the time the fence post failed.

The warranty does not cover the costs of removal or reinstatement of the fence post or any direct losses or consequential losses of any kind due to failure of the fence post. Claims must be brought, in writing, within 14 days of the discovery of the defect, though no later than 14 days following the expiry of the warranty period (25 years).

The term ‘supply’ means the date on which the fence post is delivered to the customer.
The term ‘fungal decay’ 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 fence post is no longer fit for purpose. A fence post shall be deemed as no longer fit for purpose when the fence post has suffered more than 25% mass loss at the Origin of Decay. The Origin of Decay means where the fungal decay or insect attack started.

Product Use

Just like any other product we use in everyday life the Jon Walker Timber Products Gold Label ground contact fence posts have to be used correctly to ensure they perform to their expectations.

  1. Fence posts must not have been misused or placed in abnormal conditions and must not have been used for any extraordinary purpose which was not drawn to the attention of Jon Walker Timber Products at the time of purchase.
  2. Fence posts must be fitted with a Jon Walker Timber Products Postsaver Sleeve. [See page 23 for details on current Jon Walker Postsaver Sleeves.]
  3. Should fence posts be cross cut, notched or bored during installation, then exposed surfaces must be liberally brushed with a suitable brush-on end grain wood preservative to the directions shown on the product label, to protect the integrity of the initial preservative treatment. The crosscut, notched or bored surfaces must never be used in ground contact.
  4. Fence posts must not be pointed after treatment.
  5. The shortening of fence posts should be avoided, if possible. If unavoidable the cut end must be treated with a suitable brush-on end grain wood preservative and must never be used in ground contact.
  6. Fence posts must not be planed or ripsawn.
  7. The warranty covers proven failure by the preservative system only and Jon Walker Timber Products reserve the right to allow Arch Timber Protection Limited (Lonza Wood Protection) or any other similar organisation of its choosing to investigate any claims to ensure that they are relevant and to require the return of the affected fence post to Jon Walker Timber Products or a laboratory for testing to be carried out on the affected fence post.
  8. Any claim must be accompanied by proof of purchase.
  9. Warranty and proof of purchase must be registered on our website with a grid reference and postcode.


  1. Fence posts used outside of the United Kingdom or Republic of Ireland.
  2. Fence posts removed from their original installation and re-used at a new location.
  3. Fence posts which have not been fitted correctly with a Jon Walker Timber Products Postsaver Sleeve (see Product Use – 2. Above).
