Saturate the bottom 1/3 of your posts with wood preserver and let sit overnight.
Level the surface where the wheels of the sliding gate will pass across. It may be easiest to dig up the existing surface and start over with new concrete.
Mark the location of the two fence posts based on the length of the fence and the fence gate instructions. Dig the fence post holes with the post hole digger deep enough that 1/3 of the post will be underground. Put two to three shovels of gravel at the bottom of the hole. Insert the post and then pack with concrete or dirt. Use a level to ensure the post is straight and then brace the post to keep it in place. Pile a small mound of dirt around the base of the post to prevent puddling. Let these set for four to five days.
Install the sliding fence gate according to the manufacturer’s instructions.
Things You Will Need
- Sliding fence gate kit
- Post hole digger
- Two posts
- Call your local government to make sure there aren’t any required permits and to learn the local codes if there are any.
- If the tops of the posts are slanted, rounded, or capped, water won’t collect and they will last longer.
- The post will be more secure if you make the post hole wider at the bottom than at the top.
- Read the instructions that came with your gate before you begin to be sure you have everything you need and that you understand them.
