If you’re looking to remodel a room in your home, one of the most important steps is ensuring that the foundation it rests on is properly prepared. Replacing subflooring underneath a wall can be intimidating, but if done correctly, it can make all the difference in how strong and durable your walls are over time. Doing so provides maximum security and stability for your overall structure – which means more bang for your buck when decorating or covering!
In this blog post, we’ll look at what goes into replacing a subfloor under a wall and provide step-by-step instructions along the way. Let’s get started!
What Will You Need?
Before you begin, gather the necessary materials for the job. These are given below:
- Plywood subflooring
- Circular saw
- Hammer
- Drill and drill bit set
- Wood screws
- Chalk line
- Leveler
- Masking tape
With these materials in hand, you’ll be ready to start the job and replace your subflooring.
10 Easy Steps on How to Replace Subfloor Under Wall
Step 1. Use Chalk Line and Leveler
Start by measuring how large an area you need to replace the subflooring in. Use a chalk line and a leveler to outline the space with clear, even lines. Be careful not to cut too deep – you want the leveler line to just scratch the surface.
Step 2. Cut the Subfloor
Using a circular saw, begin cutting away at the old subflooring according to how much you need to be removed. Ensure your cuts are clean and precise so that your new subfloor fits smoothly against the wall. Ensure that all pieces are the same size for a uniform look.
Step 3. Remove Old Subfloor
Once you’ve made all the cuts, use a hammer to remove your old subflooring from the wall carefully and set it aside for disposal. Take caution to ensure that no nails or other debris remain in the area – these can compromise how secure your new subflooring is when installed. Be careful not to hit or damage the wall as you remove the material.
Step 4. Prepare New Subfloor
Measure and cut the pieces of plywood needed for your new subflooring according to how large an area needs to be replaced. Ensure that each piece fits nicely against its neighbors before moving on to the next step. It is important to make sure all pieces are the same size.
Step 5. Mark Out Holes
Using a drill and drill bit set, mark out how many holes you need for your screws. Make sure the holes are evenly spaced and no more than 1/2 inch in diameter. Don’t forget to measure how far apart the holes are from each other – this will be important when you go to attach your new subflooring.
Step 6. Pre-Drill Holes
Once you’ve marked out how many holes you need, use the drill with a pre-drilled bit to create them. You’ll want to ensure that each hole is deep enough to hold the screw securely without going too far into the wall or subflooring itself. You can use masking tape to mark how far down the drill bit should go.
Step 7. Apply Masking Tape
Apply masking tape to any exposed edges on your new subflooring pieces – this will help reduce any chipping or splintering when driving in the screws later on. Don’t forget to do this step! Because the edges of the subflooring are so fragile, it’s important to take extra precautions.
Step 8. Insert Wood Screws
Grab your wood screws and begin inserting them into the pre-drilled holes. Make sure each screw is inserted securely and that there are no gaps between the wall and subflooring. If you need to adjust how far the screw goes in, you can use a longer or shorter screw, depending on how much space you have.
Step 9. Check for Level
Use a leveler to ensure your new subflooring is properly aligned and leveled with the wall. This will help ensure maximum stability over time and reduce how much wear and tear it takes from everyday use. Don’t forget to double-check that the edges of the subflooring are flush against each other and secure.
Step 10. Clean Up
Once everything is in place, clean up debris, extra screws, and wood pieces. You can use a vacuum to ensure that all remaining pieces of the old subflooring are gone. Don’t forget to finalize how to level your new subflooring before you call it a day. You’ll be glad you did for years to come!
And there you have it – 10 easy steps on how to replace the subfloor under your wall. This job can be completed quickly and easily with the right tools and materials. Not only will replacing your old subfloor make your home look more attractive, but it will also ensure that your space is safe and secure for years to come.
5 Additional Tips and Tricks
- When removing the old subfloor, use a reciprocating saw to cut through nails and screws quickly.
- When laying out the new subfloor pieces for installation, be sure to stagger them so that you don’t have two seams lined up next to each other.
- Secure the new subfloor securely by nailing or screwing every 6-8 inches along each edge and in the middle of each sheet.
- Use construction adhesive and your fasteners for added strength and stability when replacing subfloors under walls.
- Additionally, it is important to seal around any pipes or vents that come through your new flooring, as they could let moisture in and cause damage over time if not sealed properly.
Following these tips and tricks when replacing subfloors under walls will help ensure that you get a sturdy, well-installed floor. Proper sealing and proper fastening are key to a successful flooring installation. Take the time to do it right the first time for maximum satisfaction in the end result! Good luck with your project!
5 Things You Should Avoid
- Don’t start tearing out the entire subfloor. If you do, it will take a lot more time and effort to complete your project.
- Avoid using any nails or screws that are too long or wide for the subfloor boards. Nails and screws that are too large can cause damage to surrounding walls and other parts of the flooring system.
- Don’t forget to remove debris from around the wall before replacing the subfloor. Clearing away dust, dirt, and other materials will help ensure a smooth installation process.
- Don’t forget to clean up after you have finished replacing the subfloor under a wall. Use a damp cloth to clean the area and ensure the new subfloor is level.
- Avoid using materials that are not designed for use as a subfloor under walls. Different materials have different properties and will require different installation techniques. Ensure you read the instructions carefully before beginning your project to use the correct products for your job.
By following these steps, you can be sure that replacing the subfloor under a wall will be an easy and successful process!

Do Walls Go on Top of the Subfloor?
Yes, walls typically go on top of the subfloor. Subfloors provide a solid foundation that can support a wall and other elements such as cabinetry and appliances. When replacing your subfloor, it is important to ensure that it is level and secure before you begin installing any walls. If the subfloor isn’t level or properly secured, it can cause issues with how the wall sits on the floor, leading to drywall cracking or even structural damage down the line.
By correctly replacing your old subfloor, you can rest assured that your walls are safe and secure for years to come! Don’t forget to take some extra time during installation to ensure everything is level and secure before moving on to the next step. Good luck with your project!
Conclusion
Replacing the subfloor under a wall may seem daunting, but you can easily accomplish it with careful planning and specific steps. The most important factor to consider when replacing a subfloor is ensuring that the new subfloor you install follows the local building codes for your area.
Additionally, consider how much weight your floor needs to be able to handle to accommodate furniture and other objects, as well as what type of flooring you plan on installing. Don’t forget about the importance of insulation too! By considering all of these factors, you can ensure that your finished project will stay strong and beautiful for years to come.
