Fence Post Replacement Cost: How Much to Repair Broken or Rotting Posts

A single broken, leaning, or rotting fence post can compromise the structural integrity of your entire fence line. When high winds hit, an unsupported section places immense shearing strain on neighboring posts, frequently leading to multi-panel collapse.

Replacing a fence post is one of the most common residential fence repairs. Here is a full breakdown of what contractors charge, what materials cost, and how to decide whether to repair or replace.

Average Cost to Replace a Fence Post

Hiring a fence contractor or handyman to replace a single wooden or metal fence post typically costs between $150 and $350. If you are replacing multiple posts during the same service visit, the cost drops to $100 to $180 per additional post because travel, tool setup, and minimum trip fees are amortized.

Repair Scenario Estimated Cost (Turnkey) Typical Time Required
Single Post Replacement (Remove & Pour New Concrete) $175 - $350 2 - 4 hours
Gate Post Replacement (Heavy Timber / Re-Hang Gate) $250 - $450 3 - 5 hours
Multi-Post Repair (3 to 6 posts, same run) $120 - $190 per post 4 - 8 hours
Steel Post Bracket Reinforcement (No Digging) $75 - $140 per post 1 hour
DIY Post Replacement (Materials & Concrete Only) $35 - $65 per post 2 - 3 hours

Why Does Replacing a Single Post Cost So Much?

Homeowners often wonder why replacing one 8-foot 4x4 timber (which costs $14 at a home improvement store) costs $200+ in labor. The answer lies in the intense physical demolition required:

  1. Disconnecting Existing Panels: The rails must be carefully unfastened from the post without snapping aged, weathered pickets.
  2. Extracting the Concrete Footing: The old post was set in 80 to 120 pounds of solid concrete. Digging around this root ball and levering it out with high-lift farm jacks or a demolition jackhammer is backbreaking work.
  3. Digging the Hole Deeper: Any rotted wood debris must be cleared out of the hole to reach undisturbed earth.
  4. Plumbing and Bracing: The new post must be leveled precisely, braced with temporary stakes, and poured with fast-setting concrete mix.
  5. Re-hanging Panels and Disposal: The old concrete and rotted timber must be hauled away for legal disposal.

Alternative Repair: Steel Mender Brackets

If the subterranean concrete footing is still rock-solid and the post simply snapped at ground level due to sprinkler rot, you may not need to dig out the concrete. Heavy-gauge galvanized steel menders (such as the Simpson Strong-Tie E-Z Mender) can be driven between the wood post and concrete plug and bolted in place for under $50.
