How to Build a Mobile Home Basement

Adding a basement can double your living space. Although step by step detailed instructions of installing a basement is beyond the scope of this book, this broad overview will give you a good idea of how the job is completed to build a wooden basement.

A very skilled handyman could do much of the work himself, even dig the basement with a skidsteer. If you’re contemplating doing this project yourself, purchasing a good used skidsteer would be highly recommended. If you had no use for a skidsteer once the project was completed, simply sell it and you’d likely recover most of your purchase price. In this case, buying a skidsteer would definitely be cheaper than renting as you’ll need it for 3-6 months.

Preparing the Site

Step 1 – Prepare to lift the home by removing skirting and disconnecting utilities.
