Step 1: Check how the post is moving

Push the post gently from different sides to see whether it is loose at the base, leaning at the top or shifting in the ground. This helps you work out whether the fix is a simple support job or a deeper repair.

Step 2: Clear the area around the base

Dig away soil, old concrete crumbs or wet debris from around the post. Exposing the base makes it easier to see the damage and gives you room to work safely.

Step 3: Straighten and brace the post

Pull the post into position and use temporary supports to hold it upright. Check it with a spirit level before moving on, as a small adjustment now is much easier than fixing it later.

Step 4: Re-secure the base

If the hole is still sound, add gravel for drainage and top up with concrete or post mix around the base. Follow the pack guidance, then leave it untouched until fully set.

Step 5: Finish and check the fence

Once the fix has hardened, remove the braces and test the post again. If the panel or rail is putting strain on it, adjust the fittings so the load is shared evenly.

💡 Pro Tips

• Fix the post on a dry day if possible, so the ground is easier to work with.
• If the timber is rotten at the base, replacement is usually better than repair.
• Add gravel under the post mix to help water drain away.
• Keep checking the post for the first few weeks after repair.

⚠️ Safety First

Wear gloves and sturdy footwear, and take care when digging near hidden cables, pipes or sharp old fixings.
