How to Replace Rotted Floor Joist in Crawl Space in 6 Easy Steps
Knowing why you may want to replace rotted floor joists in your crawl space is only half the battle; now let’s go over how to do it. To start, you will need to gather all necessary materials such as a new floor joist, screws, a power drill, masonry anchors, and a level.

Step 1: Gather All The Tools
The very first step is to make sure you have gathered all the materials you need for the job. This includes a new floor joist, screws, masonry anchors, a power drill, and a level. Make sure all of these items are in good working order before starting the project.
Step 2: Remove the Rotted Joist
Use a pry bar or other tool to carefully remove the rotted joist. Be careful not to damage any of the surrounding joists during this process. You may also need to use a hammer and chisel to remove any broken pieces of wood that are still attached.
Step 3: Measure and Cut New Joist
Once the old joist has been removed, you will need to measure and cut the new floor joist so it fits in the space. Be sure to measure twice and cut once to ensure accuracy.

Using a power drill, attach the new joist to the surrounding joists with screws or masonry anchors. Make sure that all corners are secure and level before moving on to the next step.
Step 5: Add Support Braces
Once the joist is installed, add support braces underneath it to make sure that it will hold. These can be made out of scrap wood or purchased from a home improvement store.
Step 6: Add Insulation
If desired, add insulation to the space around the new joist to help further protect against moisture and temperature changes. This step is optional but may provide additional longevity to the new joist.

Some Additional Tips to Replace Rotted Floor Joist in Crawl Space
1. Do Not Work Alone
It’s best to have an extra set of hands when replacing a rotted floor joist in a crawl space. This will make it easier to lift and carry the lumber needed for the job as well as provide moral support during what can be an arduous process.
2. Wear Protective Gear
Crawling around in tight, dusty spaces isn’t safe for your lungs or skin. Make sure to wear a respirator mask, gloves, and a long-sleeved shirt to protect yourself from potential irritants.
3. Utilize Jack
When replacing a rotted floor joist in the crawl space of an older home, jacks can be useful for temporarily supporting the structure while new lumber is laid in place. Make sure to use a jack with sufficient weight capacity for the job at hand, and that it is securely fastened before attempting to lift any part of the flooring.
4. Ventilate The Area
To avoid the buildup of dangerous gases or other airborne contaminants, be sure to properly ventilate the crawl space during and after the replacement project. Open windows, use fans, and take breaks outside of the space to ensure that fresh air is circulating throughout.
5. Double Check Your Work
After your replacement project is finished, it’s important to double check your work to make sure everything looks secure before finishing up. This includes making sure all nails have been hammered in properly, all bolts are tight, and all connections are secure. This will help to ensure the longevity of your new floor joist and prevent unnecessary accidents in the future.
Following these tips while replacing a rotted floor joist in a crawl space can make the process much easier and safer. With adequate preparation, knowledge of the project, and patience, you should have no problem getting your replacement job done.
