Fence Post Sagging? Tips To Reinforce And Support It

Posted on: 24 September 2015

A wooden privacy fence is a great investment for your home, both for safety and appearance. If you've enclosed your backyard in a solid wood fence, it's essential that you keep it upright and secure. Sometimes, a loose or sagging fence post could leave your fencing weak and unstable. If that happens, you'll need to reinforce your fence posts to keep the structure in place safely. Here are some tips for you to deal with your fence if you notice it starting to lean.

Preparing Your Fence Repair Supplies

When you reinforce the posts, you'll be working with a concrete mixture. Since mixed concrete sets quickly, you're going to need to have everything ready before you get started.

  • Dust mask – to protect you from the cement powder
  • Level – to position the post
  • Support stakes – to hold the post
  • Trowel – to work with the concrete
  • Drill – to secure the post supports
  • Rubber mallet – for driving the post into the cement
  • Garden hose – for mixing cement
  • Bucket – for the cement mixture
  • Wood boards – to support the posts (one for each post)
  • Gravel – to fill in the base around the post
  • No-mix concrete – to fill in around the base of the post

Supporting the Posts

Dig a hole around the perimeter of the post. Remove the soil around it gradually until you create a gap of a few inches all the way around. Dig the gap so that it reaches nearly to the bottom of the post on each side.

Hammer support stakes into the ground a couple of feet out from the post. Secure the wooden board to the stakes using screws. Use the level to make sure that the post is positioned properly. Use the level to adjust the post until it is upright, then secure the post to the other end of the wooden board with the screws.

Once the fence post I supported by the wooden beam, fill the hole about a third of the way with gravel. Fill the hole with no-mix concrete, but leave it dry until you've stabilized all of the posts that need it.

After you support all of the posts, you can add water to the concrete mix with the hose. Press down on the concrete around the post to compact it. The amount of water required will vary based on how much moisture is in the soil and what kind of concrete you're using. Let the concrete set completely, then fill the top of each hole with soil. Then, remove the support structure.

If the damage to your fence is beyond what supporting the beams can fix, you'll want to consult a fence installation and repair contractor. He or she can help you with more extensive structural repairs.


Expanding Families Means Expanding Homes: Addition Building 101

When my wife and I found out we were expecting a baby, I knew that our small starter home wasn't going to be big enough for us to raise a family. We loved the house and the neighborhood though, so we didn't want to move. That's when I decided to just build an addition. From planning to construction, the process was kind of intimidating. I didn't know what to expect along the way, and that made it more difficult. I created this site to detail our experience with the construction of the addition. I hope it helps you to prepare for your next home construction project.
