How to fix a gap under a fence

There are several ways in which you can seal fencing gaps. Generally, their effectiveness depends on whichever fencing options a given homeowner has settled for.

Here are the 6 most effective fence gap-sealing ideas.

#1. Galvanized steel mesh

Hardware cloth

Hardware cloths are incredibly effective at sealing gaps under a fence. Therefore, if you have a gap that needs to be fixed, using a hardware cloth should be at the top of your list of potential fixes.

  • Start off by first measuring the fence panel length. Please do so before you even buy the hardware cloth, as it will give you a good idea of the size you should buy.
  • Create room for inserting the hardware cloth by digging along the gap.
  • Remove dirt from the area and create a trench that will allow you to insert the cloth about 3 inches into the ground.
  • After digging, place one end of the hardware cloth into the trench.
  • Use heavy-duty staples to install the other end of the wooden fence.
  • Fill back the trench with a layer of dirt. And after you fill it, tamp down the dirt. Use a shovel to pack the soil to ensure the cloth is properly secured underground.

#2. Timber planks

Cedar pickets

Cedar is durable, resistant to termites, and great at withstanding the external environment. Cedar pickets come with the same qualities, so if you have a wooden fence that has a gap, cedar pickets are a great option.

To block the gap:

  1. Cut the timber planks to fill the length of the gap.
  2. Place them horizontally
  3. Use a drill to attach them over the unwanted space.

You may have to dig under it in order to create enough space to install the pickets. And if you do so, make sure that you remember to fill and pack in the soil after installing the pickets.

#3. Concrete


You can also use concrete wall stones or blocks to seal gaps under chain-link, or any other, fencing types.

Here are the steps that you should follow.

  1. Start by digging right under the gap area.
  2. Use a tamper or a hoe to level and tamp down the layer of dirt at the bottom of the trench
  3. Create a good base for the blocks by pouring some sand into the trench. Putting enough sand into the trench until it is about an inch in thickness will also help to create a better base.
  4. Lay the concrete blocks on the sand, then stagger subsequent layers on top until you fill the gap.
  5. Finally, shore up the concrete wall with the dirt you dug up when preparing the trench.

#4. Washed river rocks or decorative stones
