How to Remove Broken Fence Posts Set in Concrete
Removing broken fence posts set in concrete can be a daunting task, but with the right approach, tools, and preparation, you can get it done efficiently. Whether your post is splintered at ground level or deeply embedded, this guide offers several methods to help you succeed.
Why It’s Important to Remove Damaged Posts
Damaged fence posts compromise the structural integrity of your fence. Replacing broken posts promptly ensures your fence remains sturdy and provides privacy, security, and aesthetics for your property. Ignoring broken posts can lead to further damage, resulting in more costly repairs down the line.
Tip: Before starting, inspect your post to determine the level of decay. If it’s severely rotted, it may be easier to remove than a post in better condition.
Common Methods to Remove Fence Posts Set in Concrete
Depending on your tools and the condition of the post, you can choose from several methods:
- Break Up the Concrete Footing
- Dig and Leverage the Footing
- Use an Eye-Bolt and Rope Method
Method 1: Breaking Up the Concrete Footing
While this method requires physical labor, it can be efficient if done correctly. Breaking up the concrete allows for easier removal and limits the size of the hole left behind, saving concrete when replacing the post.
Tools Needed:
- Heavy-duty digging bar (5 feet or longer)
- Sledgehammer or demolition hammer
- Shovel
- Safety gloves and goggles
Step-by-Step Instructions:
- Clear Out the Old Post: Smash and break apart the remaining wooden pieces using a heavy-duty digging bar. If the wood is decayed, it should splinter easily.
- Dig Around the Concrete: Use a shovel to create a gap between the concrete and the surrounding soil. Keep the digging minimal to avoid unnecessary labor later.
- Break Up the Concrete: Use your sledgehammer or demolition tool to chip away at the concrete footing. Focus on breaking it into smaller, manageable chunks.
- Remove Concrete Pieces: Pull out the broken pieces by hand. For large chunks, continue to break them down until they’re easily removable.
Method 2: Digging and Leveraging the Footing
This method is effective for posts set in loose or moderately packed soil. It requires some digging and multiple pry bars to lift the footing.
Tools Needed:
- Two or more long pry bars
- Shovel
- Blocks of wood (to use as fulcrums)
Step-by-Step Instructions:
- Excavate Around the Footing: Dig out the soil around the posthole, creating space to maneuver the pry bars. Watering the soil beforehand can make digging easier.
- Insert Pry Bars: Wedge the pry bars as deeply as possible on opposite sides of the concrete base. Use wooden blocks as leverage points.
- Leverage the Concrete Up: Press down on the pry bars to lift the concrete. Work in a seesaw motion, alternating pressure on each side.
- Pull Out the Concrete: Once the footing loosens, grab and remove it from the ground. Having an extra person to assist will make this process smoother.
Method 3: Eye-Bolt and Rope Technique
If there’s still solid wood attached to the concrete footing, this technique can be highly effective. By using an eye-bolt, you can pull the entire assembly out in one piece.
Tools Needed:
- Heavy-duty eye-bolt
- Power drill
- Drill bit slightly smaller than the eye-bolt
- Strong rope or chain
- Optional: High-lift jack or post-puller
Step-by-Step Instructions:
- Drill a Pilot Hole: Make a hole in the remaining wooden post using a drill. The hole should be narrower than the eye-bolt for a secure fit.
- Insert the Eye-Bolt: Screw the eye-bolt into the hole, ensuring it is firmly secured. Use a wrench or screwdriver for extra leverage if necessary.
- Attach the Rope: Thread the rope or chain through the eye-bolt and pull. If needed, use a high-lift jack to exert more force and pull out the concrete base.
Additional Tips for Success
Use Water to Your Advantage: Water can soften compacted soil, making digging less strenuous. Soak the ground overnight before starting your project.
Leverage Is Key: Using wooden blocks or rocks under your pry bars can make a huge difference in the amount of force you can apply.
Safety Precautions: Concrete can chip and fly when struck, so always wear eye protection and work gloves.
Consider Heavy Equipment: If you’re dealing with multiple posts or extensive damage, renting an excavator or post-puller can save you time and energy.
When to Call a Professional
Sometimes, the effort required to remove a post is too great or dangerous without the right equipment. If the footing is deeply buried or in a tricky location, professional contractors can help. They have access to specialized tools and heavy machinery that can remove even the most stubborn posts with minimal effort. Additionally, professionals can ensure the structure and alignment of your fence remain intact, reducing the risk of future issues. If you’re considering professional help, make sure to get multiple quotes to compare pricing and services.
Preventing Future Fence Post Issues
Once you’ve successfully removed the broken post and concrete, it’s important to take preventive steps to extend the life of your new fence posts. Here are some key strategies:
- Use Pressure-Treated Wood: Choose pressure-treated wood for your fence posts, as this type of wood is specially treated to resist rot, decay, and insect damage. It’s ideal for posts that will be in direct contact with soil and moisture.
- Apply a Waterproof Sealant: Even pressure-treated wood can benefit from a layer of waterproof sealant. This helps to protect the wood from water infiltration, especially in damp or rainy climates.
- Set Posts Properly: When installing new fence posts, ensure they are set at least 2 feet deep or one-third of the total post length for stability. The base of the hole should be filled with gravel for drainage, and concrete should be added above to anchor the post.
- Sloped Concrete Footing: Shape the concrete footing so it slopes away from the post. This helps direct water away from the wood, preventing moisture buildup and rot at the base.
- Regular Inspections: Periodically check your fence posts for signs of damage or rot. Early detection can prevent small issues from becoming major problems.
Pro Tip: Using a concrete post anchor can help extend the life of your posts. These metal brackets elevate the wood slightly above ground level, minimizing soil contact and reducing the risk of rot.
Comparing Methods: Which One Is Best for You?
Choosing the right method to remove a broken fence post depends on several factors, including the tools you have available, the soil conditions, and the size of the concrete footing. Here’s a quick comparison:
| Method | Pros | Cons |
|---|---|---|
| Breaking Up the Concrete Footing | Efficient with basic tools, minimizes hole size | Physically demanding, time-consuming |
| Digging and Leveraging the Footing | Less impact on the surrounding area, works well in loose soil | Requires multiple pry bars and manpower |
| Eye-Bolt and Rope Technique | Effective for posts with intact wood, less digging required | Depends on wood condition, may need additional equipment |
Consider your physical capabilities and the availability of helpers or equipment when deciding which method to use. In some cases, a combination of techniques may be the most effective approach.
More Expert Tips for Successful Fence Maintenance
Once your new post is in place, taking proactive steps can help ensure your fence remains sturdy for years to come:
Use Metal Fence Post Caps: These inexpensive caps protect the tops of your wooden posts from water damage and extend their lifespan.
Clear Vegetation Around Posts: Keep grass and shrubs trimmed around your fence posts to reduce moisture exposure and discourage pests.
Check for Soil Erosion: Soil erosion around fence posts can weaken their stability. Add soil or gravel to keep the area level and well-drained.
FAQs
Q: Can I reuse the old posthole?
A: Yes, if the hole is in good condition, you can reuse it. Just make sure to remove all old concrete and debris.
Q: How do I know if the wood is too rotten?
A: If the wood crumbles easily or has severe water damage, it’s probably too rotten to work with.
Q: What if I don’t have a digging bar?
A: You can use a heavy-duty crowbar, though a digging bar is more effective.
Q: Can a car jack be used instead of a high-lift jack?
A: Yes, but it may be less effective and require more effort.
Q: Is renting heavy machinery worth it?
A: If you have multiple posts to remove, renting can save time and labor.
Q: How deep should I dig around the footing?
A: Aim for about 6 to 12 inches deep to get enough room for leverage.
Q: Will soaking the ground really help?
A: Yes, soaking loosens compacted soil, making it easier to work with.
