Cost to Replace a Rotted or Leaning Fence Post
Replacing a rotted or leaning fence post involves releasing one fence section, removing the failed post and its old footing or debris, then setting a treated replacement in line with the fence. The work is moderately difficult because the post must be excavated, aligned with guide strings, checked for plumb, and secured before the rails go back on.
Common reasons homeowners do this job
- Decay or soft areas in the existing post
- A post that is leaning out of line with the fence
- Separation between the post and fence panels
- Damage to the existing fence post
- A worn or damaged fence post being replaced as part of an upgrade
DIY or call a pro?
This is a legitimate DIY project, but professional help is worth considering if cutting around the rails, excavating the footing, breaking concrete, or aligning the replacement post feels uncomfortable. Wear safety glasses when cutting wood or breaking concrete, wear work gloves when handling damaged wood and tools, and have another person help lift out the old post.
Frequently asked questions
- Can I replace a rotted fence post myself?
- Yes. This is a moderate DIY job when the old post can be removed safely and the replacement can be set plumb and aligned with the existing fence line. Plan for a helper when lifting the old post, especially if it breaks during removal.
- What makes fence post replacement pricing increase?
- The price scales with the number of fence posts being replaced, the labor time needed, and the materials selected. A post surrounded by an existing concrete footing can require more labor to remove.
- How deep should the hole be for a 6-foot fence post?
- For a 6-foot fence, check that the hole is at least 2 feet deep before setting the replacement post. Mark or string the fence line first so the new post can be aligned with the existing fence.
- Should concrete be sloped around a replacement fence post?
- Yes. If concrete is used, its top should be sloped above the surrounding ground so water drains away from the post. The rails are reconnected with galvanized nails, and the lower portion of the new post is treated with wood preservative.
