Is your fence about to fall over?

There are many reasons why a fence may slowly fall from its upright position to take on more of a drunken lean, but it is nothing that cannot be fixed with a little bit of work.  Sometimes the cause is obvious such as it has fallen victim to a falling branch, the kid next door has been practicing charging it as he prepares for a career in rugby or your neighbours son in an effort to learn to drive reversed his car into it.

However if it is not one of these, then it could be something a little more sinister, such as:

  • excavation of dirt on one side of the fence, resulting in the posts not having enough dirt around them to support their weight.
  • posts rotting / being eaten (for example termites) at the bottom which means the fence is not getting the stability from the depth of the post.
  • the fence is too heavy for the posts, this could be because of the fence itself or from trees or other plants putting too much pressure on the fence.

We will now look at each of these three problems and how you would go about solving them at home:

1. Excavation – The issue here is simple, without the dirt around the base of the post, the fence isn’t getting the support that it requires.  You will need to replace the dirt and ensure that it is tightly compacted around the fence post, however it is best to add concrete in with the soil to make a more solid base.

2. Rotten or eaten posts – You will need to replace the posts in question, however if the issue is termites then you will first need to address the termite issue by employing professional pest control to eradicate them.  Then replace the post using a H4-treated timber, which will ensure that the post will not rot.

3. Not enough support – Inspect the timber fence for signs of what could be causing the fence to lean, remove any branches or heavy creepers.  You may also need to demolish part of the fence to reduce the weight on the posts and then rebuild that section of the fence with additional posts to support the weight.
