Here are some step-by-step guidelines for you that you can follow to fix your floor:

Step 1: Fixing Moisture

The most common thing that can cause a saggy floor is moisture. Your floor can’t hold up to the continuous moisture damage. To fix that, you need to detect the source of the moisture.

After detecting the source, the first thing you need to do is fix up the leakage. Check alongside the saggy floor if there is any moisture leaking out. Then use a water locking tube to lock moisture. It’s like when you are fixing a water-damaged stud.

You can use a moisture barrier on the floor to prevent it from getting soggy. You can also use a vapor barrier to prevent any insect damage.

In the market, there are many different types of vapor barriers. You might find it difficult to pick the right vapor barrier for yourself. Don’t worry! Take a look at some of my recommendations for top vapor barriers:

The quality of these vapor barriers is outstanding. It will be a huge benefit to your floor.

Step 2: Removing Old Floor

Take away your wooden floor, and reveal the underneath floor. It’s more like fixing a hardwood floor. Make a few holes in the floor where it’s sagging.

Sagging can be caused by a concentration of increased weight, such as an appliance or fireplace.

You need to fill the holes with cement and add a support of your choice. Dig those exactly underneath the saggy floor.

It will help you to give straight support to the saggy floor.

Step 3: Jacking Underneath the Floor

In order to stabilize the floor, you can use jacks. These jacks can be dropped into the holes and then pulled back up.

Once they’ve reached the proper height, put extra cement around the jacks to stabilize them. You can use as many jacks as you think you will need to support the base.

Step 4: Stabilizing Jack

If you need to go higher, raise the jacks a few inches each day. You don’t want to put too much pressure on the flooring. Because that might break the flooring.

Step 5: Using Longboard

As an option, you may use longboards to support huge sections of flooring. Lay boards on top of the jacks while they are still low.

If you want to keep the structure stable, place the jacks every four or six feet.

Step 6: Replacing Damaged Base

Find out if there is any damage under the mobile home where the floor is sinking.

If your floor has been damaged by water or insects. you might be thinking of repairing it. But you may have to replace some of it also. Don’t try to jack up a floor that’s deteriorating. Your time and effort will be wasted.

You will need to remove the base underneath the damaged floor. Then use a self-leveling patch to the damaged area. It will level the sagging mobile homes underneath the floor. Then you can use mortar to stabilize the underneath floor.

You can jack up your upper floor according to the steps. With that, you can call it a day.
