Replacing the Floor of a Mobile Home

Quck answer

Replacing the floor of a mobile home can be a complex task, but it is possible to do it yourself with the right tools and knowledge. Here are the steps to follow:

1. Remove the existing flooring: Start by removing the old flooring, including any carpet, vinyl, or laminate. Use a pry bar and hammer to carefully remove the baseboards as well.

2. Inspect the subfloor: Once the flooring is removed, inspect the subfloor for any damage or rot. If necessary, replace any damaged sections of the subfloor.

3. Install new flooring: Choose a new flooring material that is suitable for mobile homes, such as vinyl planks or laminate. Follow the manufacturer’s instructions to install the new flooring, making sure to leave a small gap around the edges for expansion.

4. Replace the baseboards: Once the flooring is installed, replace the baseboards using a nail gun or adhesive.

5. Finish the flooring: Finally, apply any desired finishing touches, such as trim or transition strips, to complete the look of the new floor.

Remember to take safety precautions while working on the floor, and consult a professional if you are unsure about any step of the process.


Over time, you may come to realize that your mobile home requires a floor replacement. In fact, you might even notice the floor sinking, indicating the presence of a soft spot that needs to be repaired. Most older mobile homes have subflooring made of particle board, which is highly absorbent and prone to bowing, warping, rot, and soft spots. Even a small amount of water can cause damage. Newer homes have slightly better subflooring options, such as stronger particle board or oriented strand board (OSB), which are more resistant to water. However, they are still susceptible to bowing, softening, and warping. Regardless of the type of subflooring, the presence of a soft spot indicates the need for a floor replacement.

Removing the Existing Floor Covering

The first step is to remove the trim and floor covering. If you have carpet, you will need to remove the strips. For vinyl, cut along the perimeter of the room. Tile floors will need to be ripped up. By removing the covering, you may be able to locate a leak if that is the cause of the damage. Be sure to fix the leak to prevent harm to the new floor.

Removing the Subfloor

Next, cut out the subfloor around the edges of the room. Adjust your circular saw to three-fourths inch or five-eighths inch, depending on the thickness of the floor. Cut along the edge of the room, being careful not to damage the joists underneath. Then, cut the subflooring between the joists. Saw between the joists and remove each piece. Ensure that there are no pipes or wires in the way. You may need an oscillating tool or knife to remove the subflooring from underneath the walls.

Inspecting and Reinforcing the Joists

With the subflooring removed, inspect the joists for any damage. If a joist is damaged, you can either replace it or reinforce it with lumber of the same dimensions. Additionally, add insulation. Remember, better insulation leads to energy savings during the summer and winter seasons. Make sure the insulation is placed beneath the piping and wires.

Installing the New Subfloor

Lay the new subfloor in the same direction as the original, perpendicular to the joists. Cut the plywood to fit the width of the room. You may need to nail and glue an additional two-by-four to create a ledge for the new subfloor. Reinforce each seam with a two-by-four between the joists. Ensure that the floor is level.

Choosing the Floor Covering

Now comes the fun part. There are various options and styles for covering your floor, such as carpet, vinyl, tile, and hardwood. For bathrooms, it is recommended to use vinyl or tile to minimize water damage.
