How to replace a Rotten Fence

Replacing a Rotten Fence Post

A wooden fence post is the security net for the rest of your fence, so it is important to replace the post as soon as you notice any signs of rot. In Toronto we endure a lot of seasonal weather change. This means the harsh winter and the rainy spring are especially hard on your wooden fence post. By performing a regular look-over of your wooden fence you should be able to spot any signs of rot and damage caused over time. It only takes one rotted fence post to single-handedly take out an entire fence. Read on to discover how to remove your old post and replace it.

Materials That You Will Need To Replace a Rotten Fence Post

  • Level
  • Concrete
  • Wooden Stakes
  • Pressure Treated 2×4’s
  • Drill
  • Galvanized Carriage Bolts
  • Wheel Barrow
  • Spade (or some other type of Sharp edged tool)

1. Evaluate


Check to see if your wooden fence post needs to be replaced or repaired first. In some cases you may be able to repair the post using splints. In this case, we will teach you how to replace the post if it has completely rotted through.

  • Hold onto the post and see how wobbly it is. If the post is still held together but feels loose in the ground, you might be able to use stakes to secure it back in place. However, using a concrete base will provide longer lasting results.

2. Replace

  • With your pressure treated 2×4’s that are the same length as your old posts, cut one end on both 2×4’s and on opposite sides of the post and put them into the ground.
  • Using your level, make sure the post is leveled. This is important.
  • Drill two holes on the post and each 2×4 and bolt together using galvanized carriage bolts.

 3. Secure With Concrete



You can dig out the ground around the post and put in a temporary brace.

  • Mix your concrete together in a wheelbarrow and fill it in around the post’s base. Be sure to avoid any air pockets by using a spade.
  • Top off the concrete with soil.

Tips and Hints:

  • Depending on whether or not you are using soil to set the post or if you are using concrete – you need to make it firm. Concrete is longer lasting, but you need to make sure it’s air pocket free and tightly filled in before it dries.
  • If you have a stained/painted fence, match up your fence post with the same colour as the rest of the fence for consistency and to make the exterior of your house look great.

Replacing a rotten fence post can be done efficiently by yourself if you are careful and mindful. Always factor in safety first when completing a do it yourself project.  Replacing your fence post will give your old fence a new appearance and endure long lasting seasonal changes with periodic evaluation. We know that this could take some time away from your free weekend or in some cases could cost you time away from work – so if that’s the case, why not have HPT do it for you?
