How To Remove A Fence Post Set In Concrete

Removing an old fence post is often the hardest part of replacing a garden fence. The visible post may be rotten, cracked or leaning, while a large block of concrete remains firmly embedded below ground.

There are several ways to remove the post and its foundation. The best method depends on whether the post is timber or concrete, how large the footing is, how much working space is available and whether the old hole will be reused.

This guide explains how to remove a fence post set in concrete, which tools can help and when it may be better to leave part of the old foundation in place.

How Do You Remove A Fence Post Set In Concrete?

The most reliable method is usually to expose the concrete foundation and remove the post and concrete as one piece. Start by taking down the adjoining fence panels and gravel boards so they cannot place pressure on the post while you work.

Dig around the concrete until enough of the foundation is visible to loosen it. Work down more than one side rather than creating a narrow hole on only one edge.

Once the surrounding soil has been removed, rock the post carefully to break the grip of the ground. A digging bar or long lever can then be used beneath the concrete to raise it gradually.

Large foundations may be too heavy to lift safely. In that case, break the concrete into smaller sections or use suitable lifting equipment.

Fence Post Removal Methods At A Glance

What Tools Do You Need?

The tools required depend on the post and foundation, but a typical removal job may involve:

• A spade or trenching shovel
• A narrow post-hole spade
• A digging bar or wrecking bar
• A mattock or pickaxe
• A club hammer
• A cold chisel
• A demolition hammer for large concrete foundations
• A strong chain or lifting strap
• A suitable jack
• Timber blocks for safe support
• A wheelbarrow or rubble container
• Gloves, safety glasses and sturdy footwear

Do not use makeshift ropes, weak straps or unstable stacks of bricks as lifting equipment. Concrete foundations can be much heavier than they appear.

Check For Underground Services Before Digging

Before disturbing the ground, consider whether electricity cables, water pipes, gas services, drainage or irrigation may run near the fence line.

Look for utility boxes, drains, outdoor lighting cables, taps and nearby buildings. Old fencing may have been installed before later services were added.

Dig carefully by hand until you understand what is below the surface. Do not drive a digging bar, spike or breaker blindly into the ground.

Where the position of buried services is uncertain, obtain suitable information or professional help before continuing.

Remove The Fence Panels First

Do not start digging while the damaged post is still carrying fence panels or gravel boards. These components add weight and can move unexpectedly as the post loosens.

With slotted concrete posts, lift out the fence panels and concrete gravel boards carefully. Full-size panels and concrete boards are heavy, so two people may be needed.

Where panels are fixed to timber posts, remove the screws, clips or brackets while supporting the panel. Cut back climbing plants and remove anything that ties the fence sections together.

Temporarily support the remaining fence if removing one post leaves an adjoining section unstable.

How To Dig Out A Fence Post And Concrete Foundation

1. Clear the area: Remove plants, loose gravel, paving and other materials that restrict access.
2. Expose the foundation: Dig around at least two sides of the concrete block.
3. Remove loose soil: Clear soil from beneath the outer edges where possible.
4. Test the post: Rock it gently to see whether the concrete has started to move.
5. Insert a digging bar: Work the bar beneath one edge of the foundation.
6. Lift gradually: Raise the block a little, then pack firm timber beneath it if necessary.
7. Repeat around the base: Loosen and lift from different sides rather than forcing one point.
8. Remove the foundation: Lift or roll it out once it is free and safe to handle.

Keep the excavation only as large as necessary, but allow enough room to work safely. A cramped hole makes it difficult to get tools underneath the concrete.

Can You Pull The Post Out With A Lever?

A long lever can help remove a post where the concrete block has already been loosened. The post itself must be strong enough to withstand the lifting force.

Secure the lever to the post or work beneath the concrete foundation. Rest the lever on a solid, stable support that will not collapse or sink into the soil.

Apply pressure gradually. Sudden movement can cause the post, lever or concrete to shift unexpectedly.

This method is less suitable for a badly rotten timber post because the wood may split before the foundation moves.

How Do You Remove A Rotten Timber Post Set In Concrete?

A rotten timber post may break off at ground level when you try to rock or lift it. In this situation, the remaining timber inside the concrete cannot provide a secure lifting point.

Dig around the concrete foundation and work directly on the block. A digging bar can be used beneath the edges to loosen it.

If the block is too heavy, break the concrete around the timber. Remove the pieces gradually, taking care around sharp fragments and any old metal fixings.

Do not install a new timber post inside the rotten remains unless the opening and foundation are properly prepared for the new system.

How Do You Remove A Concrete Fence Post?

A concrete fence post and its foundation can be extremely heavy. Remove the fence panel and gravel board first, then inspect the post for cracks.

If the post is intact, it may be possible to dig around the foundation and lift the complete assembly. Strong mechanical assistance is often needed because both the post and footing contribute to the weight.

A cracked concrete post can break suddenly during lifting. Keep people clear of the direction in which it may fall and do not stand beneath a suspended post.

Where the complete unit cannot be handled safely, break the post and foundation into smaller sections. Concrete posts may contain steel reinforcement, which requires suitable cutting tools once exposed.

Can You Use A Jack To Remove A Fence Post?

A suitable jack can provide controlled lifting force. This method is often used with a strong timber post or a secure chain wrapped around the concrete foundation.

The jack must stand on a firm, level base. Use a strong timber board or another appropriate support to spread the load over soft ground.

Attach the chain or strap securely and keep it clear of sharp edges that could damage it. Lift in small stages and reposition the chain as needed.

Never place hands, feet or tools beneath a suspended concrete block. Use solid packing if the load must be held while the equipment is adjusted.

Can You Use A Farm Jack Or High-Lift Jack?

A high-lift jack can produce substantial force, but it can also become unstable if used on uneven ground or with a poorly secured chain.

The lifting point, base and load must remain aligned. Sideways loading can cause the jack to slip or kick out.

This is not a suitable method for someone unfamiliar with the equipment. A post puller, mini excavator or experienced contractor may provide better control for heavy foundations.

How Do You Break Up The Concrete?

Where the foundation cannot be removed whole, expose as much of it as practical and break it into smaller pieces.

A club hammer and cold chisel may work on a small or weak footing. Larger foundations usually require a demolition hammer with a suitable chisel attachment.

Work from the edges towards the centre. Removing smaller outer sections reduces the amount of force needed and makes the remaining block easier to move.

Wear eye protection, gloves, sturdy footwear and hearing protection where powered tools are used. Concrete fragments can be sharp and may travel beyond the immediate working area.

Can You Leave The Old Concrete In The Ground?

You may be able to leave the old foundation in place if the replacement post will be installed in a different position and the concrete does not interfere with drainage, paving or other work.

The old post can sometimes be cut below the finished ground level and the area covered with compacted soil or another suitable surface.

This method is less suitable when:

• The new post must use the same position
• The concrete is close to the surface
• The area will be paved
• The remaining post could continue to rot and sink
• The foundation blocks drainage
• The boundary position must remain precise

Leaving several old foundations can also make future fence replacement more difficult.

Can You Fit The New Post Beside The Old Concrete?

Sometimes a new post can be positioned beside the old foundation, but this changes the post centres and may affect the width of the fence panels and gravel boards.

A post installed too close to an old block may also have an irregular or undersized new foundation. The surrounding soil may have been weakened during the earlier installation.

Measure the complete fence layout before moving any post position. Standard fence panels require consistent spacing, especially when used with slotted concrete fence posts.

Removing the old foundation is usually the cleaner option where the replacement fence will follow the same line.

Can You Reuse The Existing Post Hole?

The old hole can often be reused once the concrete and loose material have been removed. However, it must be inspected and reshaped before the new post is installed.

The hole may be too wide, too shallow or irregular after removal. Loose soil should be cleared so the new post mix or concrete bears against firm ground.

Check that the replacement post is the correct length for the fence panel and gravel board. Do not reduce the post depth simply because the old hole is difficult to enlarge.

How Large Can A Concrete Foundation Be?

The size varies considerably. A small timber post may have a relatively compact footing, while a concrete post or gate post may have a much larger block.

The visible surface gives little indication of the full shape below ground. Some foundations spread wider at the base, while others are long and narrow.

Ground conditions also affect removal. Concrete can release fairly easily from sandy soil but remain tightly held in dense clay or around tree roots.

How Heavy Is A Concrete Fence Post Foundation?

Even a moderate concrete block can be too heavy for one person to lift safely. The surrounding soil and the post itself may add further resistance.

Do not judge the weight only by the section visible at the top. Assume the footing is heavy until it has been fully exposed.

Use leverage, mechanical lifting or break the concrete into smaller pieces. Trying to lift a large block directly from a deep hole can cause back, hand and foot injuries.

Can You Remove A Fence Post Without Digging?

Some posts can be pulled using a jack, post puller or excavator with only limited digging. However, exposing part of the foundation usually makes the process safer and reduces resistance.

Trying to pull a buried concrete block vertically through compacted ground may require excessive force. It can also disturb a much larger area when the block eventually releases.

A small amount of careful excavation normally gives better control.

Can You Use A Mini Excavator?

A mini excavator can remove several posts efficiently where there is safe access and enough space to work. It may be useful for large concrete posts, gate posts or a complete fence replacement.

The operator must know the location of buried services and understand how the post may move as it is lifted.

Machine weight can damage lawns, paving, drainage and soft ground. Check access widths and overhead obstacles before arranging equipment.

How Do You Remove A Post Close To A Wall Or Paving?

Restricted access makes removal more difficult because there may be no room to dig evenly around the foundation.

Lift paving carefully where possible and store reusable slabs away from the work area. Avoid levering directly against a brick wall, retaining wall or fragile paving edge.

A narrow chisel attachment can be used to reduce the foundation in place. Work slowly to avoid damaging adjacent structures.

If the post supports a garden gate or stands close to a building, professional removal may be the safer option.

How Do You Remove A Gate Post Set In Concrete?

Gate posts often have larger foundations than ordinary fence posts because they carry moving weight and sideways leverage.

Remove the garden gate and ironmongery before starting. Support any attached fence section and clear enough space for the post to fall or be lifted safely.

Expect the footing to be deeper or wider than those beneath the surrounding fence. Mechanical assistance or concrete breaking may be needed.

When replacing it, choose a gate post and foundation suitable for the gate's width, weight and exposure to wind.

What Should You Do With The Concrete Waste?

Concrete and broken fence posts should be separated from ordinary garden waste. Small amounts may be accepted at an appropriate local recycling facility, subject to its current rules.

Do not bury sharp rubble in the garden or leave broken concrete where it can interfere with drainage and future digging.

Concrete posts may contain steel reinforcement. Keep exposed metal safely contained during handling and transport.

How To Prepare The Hole For A New Fence Post

1. Remove all loose debris: Clear broken concrete, rotten timber and loose soil.
2. Check the hole position: Confirm the fence line and required post centres.
3. Check the depth: Make sure the hole suits the new post and completed fence height.
4. Reshape the sides: Remove unstable edges so the foundation bears against firm ground.
5. Position the new post: Use a string line and spirit level to keep it aligned.
6. Support the post: Fit temporary braces before adding the setting material.
7. Add post mix: Follow the water quantity, installation method and setting guidance on the packaging.
8. Check the spacing: Confirm the fence panel and gravel board dimensions before the mix firms.
9. Allow the foundation to set: Do not load the post with panels or a gate too soon.

Should You Use Post Mix For The Replacement?

Post mix is a practical choice for most standard garden fence posts. It is supplied ready blended and avoids the need to measure separate amounts of cement, sand and aggregate.

Position and support the post before adding the product because post mix is designed to set quickly. Follow the instructions supplied with the bag, including the amount of water required.

The new foundation still needs a suitable hole. Post mix cannot compensate for poor alignment, loose ground or an undersized excavation.

Can You Repair The Post Instead Of Removing It?

A damaged timber post may sometimes be supported with a concrete repair spur. This avoids removing the existing foundation and can be useful where the post has failed near ground level.

The remaining timber must be sound enough to attach securely to the spur. The repair also needs to keep the fence upright and correctly aligned.

A badly rotten post, broken concrete post or failed gate post is usually better replaced. A repair should not be used merely to avoid difficult excavation where the finished fence would remain unstable.

Common Fence Post Removal Mistakes

• Digging without checking for buried services
• Leaving fence panels attached while loosening the post
• Trying to lift a large foundation by hand
• Using weak rope or unsuitable lifting straps
• Standing beneath a suspended concrete block
• Levering against paving, walls or fragile garden structures
• Using a demolition hammer without eye and hearing protection
• Assuming a rotten timber post will provide a secure lifting point
• Moving the replacement post without checking panel spacing
• Leaving loose concrete in the hole before installing the new post
• Loading the replacement post before the post mix is ready
• Failing to support the remaining fence during removal

When Should You Use A Professional?

Professional help may be sensible where the post is close to buildings, buried services, retaining walls or expensive paving.

It may also be appropriate where:

• The post is a large concrete gate post
• Several foundations need removing
• Mechanical equipment is required
• Access is restricted
• The post contains exposed reinforcement
• The fence borders a public area
• The remaining fence cannot be supported safely

A contractor with suitable lifting and breaking equipment may complete a difficult removal with less disturbance to the surrounding garden.

FAQs

What Is The Easiest Way To Remove A Fence Post In Concrete?

For a manageable foundation, dig around the concrete, loosen the soil and lift the post and block together using a digging bar or suitable jack. Large foundations are usually easier to remove after being broken into smaller pieces.

Can You Pull A Concreted Fence Post Out With A Car?

This is not recommended. Tow ropes, chains and attachment points can fail, while the post may release suddenly and cause damage or injury. Use controlled lifting equipment designed for the task.

How Far Around The Concrete Should You Dig?

Expose enough of the block to understand its shape and get a lever beneath it. Digging around two or more sides usually provides better control than working from one narrow trench.

Can You Dissolve Concrete Around A Fence Post?

Chemical concrete removers are not a practical solution for a substantial buried foundation. Mechanical digging, lifting or breaking is normally required.

Can You Burn A Rotten Post Out Of Concrete?

No. Burning timber in the ground is unsafe, difficult to control and may damage nearby fencing, plants and services. Remove the timber and concrete mechanically.

Can You Reuse A Concrete Fence Post?

An intact post may sometimes be reused, but removing it without cracking the post can be difficult. Inspect the slots, reinforcement and full post length before deciding.

Can You Reuse The Old Concrete Foundation?

Usually not for a replacement post unless the system has been specifically designed for it. The old hole may contain rotten timber, cracks or unsuitable dimensions. A new properly formed foundation is more reliable.

How Do You Remove A Post Broken At Ground Level?

Dig around the foundation and work directly on the concrete. Use a digging bar beneath the block or break the concrete into smaller pieces if there is no sound post available for lifting.

Can You Put A New Post Into The Old Concrete?

Only where the old post can be removed cleanly and the remaining opening is suitable for a purpose-made repair method. Simply pushing a new post into an irregular hole is unlikely to provide reliable support.

How Long Should You Leave New Post Mix Before Fitting Panels?

Follow the setting and loading guidance printed on the product packaging. Rapid initial setting does not always mean the foundation is ready for the full weight and wind load of the fence panels.

Remove The Whole Foundation Where Possible

The cleanest way to remove a fence post set in concrete is to expose and lift the complete foundation. This leaves a clear hole that can be checked, reshaped and reused for the replacement post.

Where the block is too large, break it into manageable sections rather than attempting an unsafe lift. Keep the surrounding fence supported and take particular care with concrete posts, gate posts and foundations close to walls or paving.

Once the old material has been cleared, install compatible fence posts, fence panels and gravel boards as one system. Use suitable post mix, check the spacing before it sets and allow the new foundation to develop enough strength before rebuilding the fence.
