Embarking on a deck renovation project often involves removing old or damaged posts, especially when they’re set in concrete. This task might seem daunting, but with the right tools and techniques, it’s entirely manageable. Let’s delve into the step-by-step process of removing deck posts from concrete, ensuring your project runs smoothly and safely.
Before we dive into the process, it’s crucial to understand that this task requires patience, the right equipment, and a good understanding of the structure you’re working with. Always prioritize safety by wearing appropriate protective gear, including gloves, safety glasses, and sturdy work boots.

Preparation and Gathering Tools
Before you start, ensure you have all the necessary tools at hand. This will save you time and prevent any potential delays. Here’s a list of tools you’ll need:
- Sledgehammer
- Chisel
- Circular saw
- Drill with a masonry bit
- Hammer drill (optional, but helpful for larger posts)
- Angle grinder with a masonry blade
- Safety gear (gloves, safety glasses, work boots)
- Tape measure
- Level
- Post hole digger
- Shovel
- Wheelbarrow
Assessing the Situation
Before you start removing posts, it’s essential to understand the layout of your deck and the posts’ locations. Measure the distance between each post to ensure you maintain the deck’s structural integrity when removing them. Also, check for any utility lines that might be in the way. Always call your local utility company to mark any underground lines before you start digging.
Once you’ve assessed the situation, mark the posts you intend to remove with spray paint or chalk. This will serve as a visual guide during the removal process.

Removing the Concrete
Start by removing the concrete around the post. You can use a sledgehammer and chisel to break up the concrete, or an angle grinder with a masonry blade for larger posts. If the post is set deep in the concrete, you might need to use a hammer drill or a regular drill with a masonry bit to create pilot holes, which will make the process easier.
Be careful not to damage the post while removing the concrete. If the post is still in good condition, you might be able to reuse it. Once you’ve removed enough concrete to expose the post, use a post hole digger to remove the remaining concrete from around the post.
Removing the Deck Post
With the concrete removed, it’s time to remove the post itself. If the post is still in good condition, you can use a reciprocating saw or a circular saw to cut it off at ground level. If the post is damaged or you’re not sure about its condition, it’s best to remove it in one piece.

To remove the post in one piece, use a post hole digger to loosen the soil around it. Then, use a pry bar or a crowbar to lift the post out of the ground. You might need to use a sledgehammer to tap the post loose if it’s stuck. If the post is too large to remove in one piece, you can cut it into smaller sections using a circular saw or an angle grinder.
Repairing the Hole
Once you’ve removed the post, you’ll be left with a hole in the ground. It’s essential to fill this hole to prevent accidents and maintain the structural integrity of your deck. Use a post hole digger to loosen the soil at the bottom of the hole, then fill it with gravel or crushed stone. This will help with drainage and prevent the new post from rotting.
After filling the hole with gravel, use a level to ensure the ground is even. Then, fill the rest of the hole with soil, compacting it as you go. Finally, use a rake to smooth out the surface and blend it with the surrounding ground.
Installing a New Post
With the hole filled and the ground leveled, it’s time to install a new post. Measure and cut the new post to the correct length, then use a level to ensure it’s plumb. If you’re using a new post, you might need to use a post hole digger to create a new hole. If you’re reusing an old post, you can simply place it in the existing hole.

Once the post is in place, use concrete to secure it. Fill the hole with concrete, ensuring it’s level with the ground. Allow the concrete to cure for at least 24 hours before using the deck. After the concrete has cured, you can install a new beam or joist to replace the one you removed.
Removing deck posts from concrete can be a challenging task, but with the right tools and techniques, it’s entirely manageable. Always prioritize safety and take your time to ensure the job is done correctly. With a little patience and elbow grease, you’ll have your deck looking as good as new in no time. Happy renovating!
