7 Steps to Follow on How to Extend a Concrete Porch with Wood

Step One: Measure and Create a Plan

Take Accurate Measurements

Before beginning any construction project, it’s important that you take accurate measurements of the space you are working in and create a plan. This will help ensure that your materials are ordered correctly and that you don’t run into any surprises during the building process.

Make sure to measure from the edge of the existing concrete porch and account for any obstructions in the area (e.g., shrubs, trees). The plan should also include what type of lumber you need, how much it costs, and where it will be placed on the porch.

Step Two: Prep Your Area

Once you have measured your area and created a plan, it’s time to prep it. This includes ensuring that all debris is removed from the area before beginning construction.

You should also ensure that there are no obstructions blocking your workspaces, such as plants or furniture items that could get in the way while you are building. Additionally, this is a good time to check for potential safety hazards such as uneven surfaces or exposed wires.

Step Three: Install Deck Post Anchors

Next, it’s time to install deck post anchors into the concrete flooring around your existing porch. These anchors will hold up the wooden posts, which will support your new extension.

When drilling into concrete, make sure that you use an appropriately sized masonry bit and wear protective eyewear—masonry drills can emit small particles when drilling, which can cause eye damage if not properly protected against.

It may also be helpful to use some sort of template or guide when installing deck post anchors so that they all line up evenly on each side of the porch extension. 

Step Four: Cut and Attach Lumber

When Cutting the Wood

Now it’s time to start cutting the lumber to the size that is specified in your plan. Make sure you use a saw or other sharp tool when cutting the wood so that all your pieces are uniform and fit together properly.

Depending on how long your extension will be, you may need to use additional support posts or beams in between the deck post anchors. Once all of your pieces have been cut, attach them using wood screws and a drill.

Step Five: Install Decking

Now it’s time to install the decking for your porch extension. First, make sure that the boards fit snugly together side by side and are secured firmly with nails or screws.

If necessary, you can add more support posts between existing ones to ensure that everything is properly supported. Additionally, ensure that any gaps between boards are filled with weatherproof material such as caulk or concrete sealant.

Step Six: Add Finishing Touches

Once your porch extension is built, you can add finishing touches. This includes adding a railing or decorative trim for aesthetic purposes and any additional safety features, such as stairs or handrails. Again, make sure to use high-quality materials when installing these additions so that they will last and be safe for everyone who uses them.

Step Seven: Enjoy Your New Porch Extension!

Things You Need to Know Before Extending a Concrete Porch with Wood

Making a concrete porch into one made of wood is an exciting project to take on. Before you start, however, it’s important to understand the task and some aspects to keep in mind. Depending on your existing porch, you may need to enlist the help of contractors or professionals who are experienced in construction and demolition; this will ensure a safe job.

Moreover, if you are replacing an existing porch or installing a new one, ensure that your design complies with local building codes; permits may be required depending on the size and scope of work.

Additionally, be sure that the sub-base is level for optimal installation outcome. Considering all these things before beginning your project will make for an easier extension process.

Benefits of Extending a Concrete Porch with Wood

Adding a wooden extension to a concrete porch can be an excellent way of extending your entertaining space outdoors. The beautiful, natural look of wood adds a nice aesthetic to the existing concrete structure, creating an inviting and unique atmosphere.

Wood extensions are also very useful in protecting furniture from rain, sun, or other elements. Additionally, carpentry work is relatively inexpensive when compared to labor costs associated with laying down additional concrete areas around your home.

Concrete is also more stringent for expansion than wood, thus helping to reduce the risk of any cracks or damage forming that could compromise its integrity. In sum, extending a concrete porch with wood can provide many benefits in terms of aesthetics and functionality!

4 Common Mistakes People Make When Trying to Extending a Concrete Porch with Wood

1. Not Using the Right Materials

One of the most common mistakes people make when extending a concrete porch with wood is not using the right materials. The wood you use for the extension needs to be able to withstand the elements and any foot traffic that will be on it. You also need to ensure that the wood is properly sealed, so it does not rot or warp over time.

2. Not Preparing the Base

Another mistake people make is not preparing the base before they start building the extension. The ground needs to be level and compacted before you start laying down the foundation for the extension. If you do not prepare the base properly, the extension will not be stable and could eventually collapse.

3. Not Attaching the Extension Properly

The extension needs to be securely attached so that it does not come loose over time. Make sure to use lag bolts or other heavy-duty hardware to attach the extension to the concrete porch.

Sure to Use Lag Bolts

4. Not Finishing the Extension Properly

The last mistake people make is not finishing the extension properly. This includes adding a layer of sealant or paint to protect the wood from weathering and wear and tear. Adding trim around any edges or joints is also important to give the extension a finished look.


Building an extension onto a concrete porch with wood can be done relatively easily with proper planning and preparation!

By following these steps—measuring out your area, prepping for construction, installing deck post anchors—you can easily add an outdoor living space complete with wood decking that adds value to your home and provides extra room for entertaining guests!
