Supplier PRO

As a producer of long life fencing products, we're always interested to hear about peoples experiences using timber fence posts. We're seeing more and more fence post failures from unprotected timber and the damaging effects it can have on peoples reputations. Have you carried out fencing work and then had a call back due to rotting posts a few years later? What effect has this had on your business? Alternatively, are you customers aware of ground line decay and have they requested anything to prevent it?

  • hi Ricard i do not know what  products you produce but the thing with timber nowadays is the product that it is treated with and the way its treated and the maintainance (or lack of it) that it gets every year i used to paint a fence with proper creasote that was 15 years old and got compleatley overtoped from the river that flooded at least twice a year 

    adding things to wooden posts at a cost plus the post starts bringing it into line with concreat posts they are ok if you are replacing a odd post because there is no option because of the size difference

      Hi David, Postsaver make dual-layer barrier sleeves which prevent ground line decay and guaranntee a post lifespan of 20-years, provided the criteria such as use of a UC4 post are fulfilled. They start at £1.22 a sleeve.

      Like you say it's the modern methods of treatment and often fast grown spruce timber that is to blame for early failures. We've even heard reports of fence post failures before the 5-year mark.

      Interesting to hear your feedback!


  • I work in an area of high rainfall.  Most "pressure treatment" is totally inadequate.  I always soak the posts in preserative before use & either fit a cap or treat the top as a lot of rot is cause by water ingress from the open grain at the top.

    Another factor is to ensure that the post hole can drain.

      Current pressure treatments are not what they used to be and even a UC4 post offers little protection. Have you ever had to replace posts you have fitted yourself or do you find your methods are successful? Curious to see what sort of time scales people are replacing posts on. I have spoken to some contractors who had call backs to replace posts after ony 5 years!

      • 6 years on a 100mmx100mm section tanalized post. Only holding a four foot panel, quite sheltered, soil also sandy and dry. Post cut to length at the 'top' and post cap fitted.
