What Is Underpinning On A Mobile Home

What does underpinning on a mobile home mean? If you have built your house on some kind of foundation, but then wanted to move it somewhere else, you would need to remove the old supports and put some new ones in. This is called underpinning.

Pretty much anything that is supporting something can be said to be “underpinning” it.

Underpinning On Mobile Home

Underpinning a mobile home is the same as putting support beams underneath it. If you were to try and move your home without underpinning, the foundation of the house would probably collapse due to the weight/pressure of everything above it.

Underpinning is an expensive process. Some ways of keeping costs down include hiring a company (rather than doing it yourself) for moving, re-hiring a realtor to find a new lot for your mobile home after it’s been moved, and getting a cheaper mobile home insurance plan.

How to Underpinning on a mobile home?

Here are some steps to follow for underpinning a mobile home:

  1. Remove the existing beams and supports. These can be found under your home around where it touches the ground.
  2. Measure out how much space you need to put beams in, and make sure to leave extra room for error.
  3. Drive new wooden beams into the ground underneath your mobile home (in safe, pre-measured places).
  4. Use heavy equipment like cranes or forklifts to move the mobile home back onto its original foundation.

How Much Cost to Underpinning a Mobile Home?

The cost of underpinning a mobile home varies based on several factors: how good of a condition your mobile home is in, how long it takes to do the job and who you hire (or if you do it yourself).

Underpinning a mobile home costs around $10 per square foot.

This means that for minimum work on an older mobile home, you would need to pay about $7500 before taxes and other fees.

What Do You Use For Underpinning?

Beams and supports. Beams need to be at least 5-8 inches in diameter, plus 3-6 feet of length for each section. This means that you will need around 4 beams for every square foot of underpinning work done on your mobile home. The more beams that are used, the greater the support you have under your house.

If you cannot afford to hire people to help you with the job, consider getting a do it yourself kit online where it has all the materials needed for you to make your place safe again by yourself.

FAQs – Underpinning On Mobile Home

How do you install underpinning for a mobile home?

There are a few different ways that you can go about installing underpinning for a mobile home.

  • One way is to simply pour concrete footings around the perimeter of the home.

What is the Purpose of Skirting on a mobile home?

Mobile homes need to be skirted to protect the area around them from damage or dirt that could potentially cause environmental concerns or property value issues.

The skirts that go underneath a mobile home should touch all four sides and not be less than three feet away from any other buildings.

It is also important to make sure that there’s a slope coming off of the skirt at least 1/4 inch every 4 feet around the mobile home, this prevents water from becoming stagnant.

Ultimately, whether or not you choose to install skirting on your mobile home is a personal decision.


The underpinning of a mobile home is what supports the frame and prevents it from tipping over. It also helps to stabilize the foundation so that you can rest easy knowing your house won’t be going anywhere anytime soon!

A mobile home is underpinned by a number of different materials, including blocks, beams, screw piles and concrete. 

The choice of material used to underpin a mobile home will depend on the conditions of the ground it is being installed on. 

Underpinning a mobile home with screw piles is becoming increasingly popular as it is an affordable and quick way to stabilize a mobile home. 

If you’re considering installing or buying a mobile home, be sure to talk to your local specialist about the best way to underpin it.
