Mobile homes offer a unique and affordable housing option for many people. However, just like traditional homes, they require proper maintenance to ensure their longevity and stability. One crucial aspect of maintaining a mobile home is underpinning. Underpinning involves adding support to the foundation of your mobile home, helping to stabilize it and protect it from environmental factors like soil movement and weather changes. In this article, we will explore various mobile home underpinning options, the benefits of underpinning, and how to choose the best option for your home.
What is Mobile Home Underpinning?
Before we dive into the different underpinning options, it’s essential to understand what underpinning is and why it’s necessary for mobile homes. Underpinning refers to the process of strengthening or supporting the foundation of a building, in this case, a mobile home. Over time, soil beneath a mobile home may shift, causing the structure to become unlevel or unstable. Underpinning helps to prevent this by providing a stable base for the home.
In mobile homes, underpinning not only stabilizes the foundation but can also improve insulation, enhance the home’s appearance, and increase its resale value. There are various underpinning methods available, each with its pros and cons.
Types of Mobile Home Underpinning Options
1. Concrete Block Skirting
One of the most common mobile home underpinning options is concrete block skirting. This method involves placing concrete blocks around the perimeter of the home to create a stable and solid base. Concrete block skirting is highly durable and can provide a long-lasting solution to underpinning needs.
Advantages:
- Durability: Concrete blocks are strong and can withstand various weather conditions.
- Affordable: This is one of the more cost-effective underpinning options for mobile homes.
- Ease of installation: Concrete blocks are relatively easy to install compared to other methods.
Disadvantages:
- Aesthetic limitations: Concrete blocks can be unattractive if not properly maintained or finished.
- Potential for shifting: Over time, the blocks may shift if not installed correctly, leading to gaps or uneven surfaces.
2. Skirting with Vinyl Panels
Vinyl skirting is another popular choice for mobile home underpinning. It involves installing vinyl panels around the base of the home. These panels are lightweight and come in various colors and textures to match the home’s aesthetic.
Advantages:
- Aesthetic appeal: Vinyl skirting offers a clean, attractive look and can be customized to suit the style of the mobile home.
- Easy installation: Vinyl panels are easy to install and can be a DIY project for homeowners with some basic skills.
- Low maintenance: Vinyl requires minimal upkeep, as it doesn’t rust or rot.
Disadvantages:
- Durability concerns: While vinyl skirting is resistant to the elements, it can become brittle and crack over time, especially in colder climates.
- Not as sturdy: Vinyl is not as strong as other underpinning materials, and it may not provide the same level of structural support as concrete or brick.

3. Brick or Stone Skirting
For homeowners looking for a more durable and visually appealing underpinning option, brick or stone skirting is a great choice. This method involves using bricks or stone to create a permanent and sturdy foundation for the mobile home.
Advantages:
- Strength: Brick and stone provide excellent structural support, helping to keep the mobile home level and secure.
- Aesthetic appeal: This option gives the home a more permanent, traditional appearance, adding curb appeal and value to the property.
- Low maintenance: Brick and stone are low-maintenance materials that can last for decades.
Disadvantages:
- High cost: Brick and stone are more expensive than other underpinning options.
- Labor-intensive: Installation can be more time-consuming and may require professional help, increasing labor costs.
4. Insulated Concrete Forms (ICF)
Insulated Concrete Forms (ICF) are another advanced underpinning option for mobile homes. This method involves using interlocking foam blocks that are filled with concrete to create a solid and insulated foundation. ICF provides excellent thermal insulation, helping to regulate the temperature inside the home and reducing energy costs.
Advantages:
- Energy efficiency: The insulation provided by ICF can help keep the mobile home cooler in the summer and warmer in the winter.
- Strong foundation: ICF creates a robust and stable foundation for the home.
- Long-lasting: ICF systems are durable and require minimal maintenance over the years.
Disadvantages:
- Higher initial cost: While ICF is an excellent long-term investment, the initial installation cost can be higher than other underpinning methods.
- Complex installation: ICF requires specialized knowledge and tools for installation, so professional assistance is usually needed.
5. Pier and Beam Foundation
A pier and beam foundation is another method of underpinning for mobile homes. This method involves placing piers, typically made of concrete or wood, beneath the mobile home and supporting it with beams. The piers are strategically placed around the home to distribute the weight evenly and prevent the home from shifting.
Advantages:
- Cost-effective: Pier and beam foundations are relatively affordable compared to other methods.
- Accessibility: This type of underpinning makes it easier to access plumbing and electrical systems beneath the home.
- Flexibility: The piers can be adjusted if needed to level the mobile home in the future.
Disadvantages:
- Vulnerability to weather: Pier and beam foundations can be affected by soil conditions, including excessive moisture or shifting soil, which can cause the piers to settle unevenly.
- Maintenance: Over time, the piers and beams may require maintenance or adjustment to ensure the home remains level.
6. Steel Skirting
Steel skirting involves using metal panels or sheets to enclose the area beneath the mobile home. Steel is a strong and durable material that provides solid support while also offering an attractive finish.
Advantages:
- Strength and durability: Steel is incredibly strong and resistant to the elements, providing long-lasting protection.
- Aesthetic appeal: Steel skirting has a sleek, modern look that complements many mobile home designs.
- Low maintenance: Steel is resistant to rust and decay, making it an easy material to maintain.
Disadvantages:
- Higher cost: Steel skirting is generally more expensive than vinyl or concrete options.
- Potential for dents: Although durable, steel can be dented if subjected to heavy impacts.
How to Choose the Best Mobile Home Underpinning Option
Choosing the best underpinning option for your mobile home depends on several factors. Here are some things to consider when making your decision:
- Budget: Different underpinning methods come with varying price tags. If you’re on a tight budget, concrete block skirting or vinyl panels may be your best option. However, if you have more flexibility in your budget, you may want to explore options like brick or ICF for added durability and insulation.
- Climate: Consider the climate in your area when selecting underpinning materials. For instance, if you live in an area with extreme temperatures, insulated options like ICF or insulated skirting can help regulate the temperature inside your home. In more temperate climates, concrete blocks or steel skirting may suffice.
- Aesthetics: If you value the appearance of your mobile home, you may want to choose underpinning materials that complement its design. Brick, stone, or steel skirting offers a more polished, permanent look, while vinyl and concrete blocks can be functional but may require additional finishing to enhance their visual appeal.
- Maintenance: Some underpinning options, like vinyl or concrete blocks, require more frequent maintenance to prevent cracking or shifting. If you want a low-maintenance solution, steel or brick skirting may be better suited to your needs.
- Longevity: If you plan on staying in your mobile home for many years, investing in more durable underpinning materials such as brick, stone, or ICF may provide long-term benefits and save you money on repairs down the road.
Conclusion
Mobile home underpinning is an essential part of maintaining the stability, appearance, and insulation of your home. The various mobile home underpinning options available allow homeowners to choose a solution that best suits their needs, whether it be cost, durability, or aesthetics.
