How to Jack up a Mobile Home; 6 Easy Steps

Find the Sagging Surface Inside the Home

Find uneven surface

Look for the sinking spot in your home before going under. You will easily find the point under the house once you know where the sinking or structure problem above is. If the issue is in the window, door, or a crack in a wall, you’ll have to level the area around it.

A bubble level will be handy to notice the uneven spot. Say, if you see the floor sagging, place it in that location. If the bubble is not in the middle, then you’ve found the sagging.  

To make the job easier for you, let’s hear a bit about the spirit level. If the bubble is towards the left of the level, the sagging spot is to the right of the spirit level, and vice versa. A laser is also helpful if you don’t have a bubble level. Check the video below for using lasers to spot sinking areas.

Locate the Uneven floor Under the Mobile Home

Since you’ve spotted the bulging area inside the house, it’s now easier to find it underneath your mobile home. Get under the house and reach the area that is sagging inside your home. Then locate the pillar near or around the spot that causes the sinking. 

Find a Jack Point below the Beam

Place your jack under the beam, near the pillar that’s causing the problem. Lift the shaft with the jack. Raise the area just a few inches to prevent over-raising. In some cases, lifting one pillar may not be enough to level your home. If that’s the case, check the other pillars as well. And you may need more jacks for multiple beams.

Slide a Wedge Between the Beam and the Pillar

Insert a wedge

Fill the gap with a wedge or a block after raising the beam. The wedge should be strong enough to support the weight. And the wedge should also be of enough size that you can easily fill the void. Don’t tighten the wedge for now. 

Check the Level Again

After placing the wedge, come out of the crawl space and get inside your mobile home. Check the sinking area with the tool or the method you’ve used before. If the problem was in a window or door, check out whether that works better now.

Remove the Jack

If you’ve solved the issue already and there is no more sinking, get under the home and tighten the wedge you’ve placed before. Hit the wedge with a hammer so that it sticks in the gap. After doing your job, lower the jack and remove it.

But if there still is a problem. Place the jack under another beam nearby. You can guess which other pillars would have sunk in the soil. Then raise the beam and again check whether you’ve resolved the issue or not.
