Fencing Warranty


15 year guarantees & warranties ….. what do you need to know?


Some suppliers just don’t offer one, some posts are very cheap, some have been known to rot and break in as little as 3-4 years !

Some have guarantees or warranties on them – but many of these are 6 -10 A4 pages long of very small print of terms & conditions making it very clear that claiming under that warranty would be very difficult indeed

Some warranties are provided by timber importers who mysteriously go out of business and start again with a different name every 5 years. It would be cynical to suggest this was to avoid accumulating liabilities, but it is certainly one of the effects on you, the end client


Our Warranty


And there is our warranty which applies to all our round posts and can be identified by a dated metal nail head in the top of the post.

Firstly – it is underwritten by Arch chemicals – the manufacturer of the TANALITH E timber treatment itself. Not us, not the mill, but the chemical company themselves. These guys have been producing timber treatments for all sorts of industries for over 80 years – take a look at their website - http://www.archtimberprotection.com/who-we-are/


Secondly – there is the simplicity of it. A single A5 page of ‘non legalese’ text that reads like this:


'The Treat-Right warranty on incised (incised means the posts have very small slits made in them at the mill to enable the treatment to penetrate deeper into the post. This is only done on the bottom third of the post where rot is a risk and this then doesn’t affect the appearance of your fence) round fencing stakes from our timber mill is based on using TANALITH E 8000 wood reservative and carrying out the high pressure treatments according to the current Lonza Wood Protection Code Of Practice for Tanalith E wood preservative and other relevant parts of BS8417'

'These fencing stakes have been treated for class 4 applications (ground contact) and have a 15 year warranty against failure of the timber from fungal decay or insect attack'


The warranty covers the replacement of the timber that has failed only, not the cost of removal, re-installation or subsequent losses. This is the same for all the timber warranties.

The warranty is against failure due to fungal decay or insect attack, these are clearly explained in two short easy to understand paragraphs:


'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'

'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.

Some rumours are that if the post is cut, notched, stapled or anything else ridiculous then the warranty is void. Ours is not like this and again is laid out is 7 simple points:

1.  The treated timbers 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 the retailer  & mill at the time of purchase.  So don’t use them for submerged sea walling or other extreme use and think the warranty will cover them

2 Should the treated timbers be cross cut, notched or bored during installation, then the exposed surfaces must be liberally brushed with Ensele end grain wood preservative the the directions shown on the tin to protect the integrity of the treatment. So our posts can be cut, notched, drilled etc. as is normal for many posts, they just need to be brushed with ensile afterwards. Any good contractor will be doing this anyway.

3. Treated timbers must not be pointed after treatment Ours are all pointed before treatment at the mill.

4. The shortening of treated timbers should be avoided if possible, but in any even the cut end must never be in ground contact simple enough. If you do shorten the post, cut the top off, not the bottom and reseal with ensile.

5. Any treated timbers which are further processed, eg planed or cut along the length must be returned for re treatment again simple enough. The treatment penetrates from the outside and if you cut deep enough into the post, this will be compromised. So if you need different shaped posts, order them shaped and treated in the first place.

6. Any claim must be accompanied by proof of purchase like all warranties, your receipt / invoice is also needed.

7. Any treated timbers removed from their original installation and re-used at a new location are excluded.


 That’s it. Simple, clear and honest.


If you want posts with a warranty you can be confident in – call us - 01992 578496.


If you are tempted by cheap posts with an alleged warranty, take these three steps:

1.  Ask for a copy of the warranty and see how readily it is supplied and how simple it is to understand.

2.  Think that a new car – between £10,000 £50,000 or more comes with a 3 – 7 year warranty depending on the brand at best. This is a product that is between £3.00 & £10.00 typically, so saving 50 pence per post could be a very false economy.

3.  If you are convinced that the best materials come at the very cheapest prices, then I have a mate who sells Rolex watches for £50.00 each... Can I pass on your number ?
