A vapor barrier is a protective layer, usually made of thick plastic, that blocks moisture from rising up into your mobile home from the ground. In simple terms, it acts like a moisture shield under your home. Without it, water vapor from the soil can seep into your crawl space, leading to mold, mildew, wood rot, soft floors, and insulation damage, especially in older or unsealed mobile homes.
Vapor barriers are typically installed beneath mobile homes, especially in the crawl space area, but they can also be used under floors or inside walls for extra protection. At Guardian Vapor Barrier, we focus specifically on vapor barrier installation and repair for mobile homes, helping homeowners maintain a healthier, more energy-efficient space. In Largo, FL, where heat and humidity are high year-round, moisture problems are common. That’s why having a quality vapor barrier is essential for protecting your mobile home.
Types of Vapor Barrier Materials: What Are Your Options?
Plastic Sheeting and Polyethylene
Plastic sheeting, usually made from polyethylene, is the most common and affordable vapor barrier option. It comes in various thicknesses, typically from 6 to 20 mil, and can offer solid protection when installed correctly. While cost-effective, thinner sheets may tear easily, making thickness and durability important considerations for mobile home use.
Reinforced Vapor Barriers
Reinforced vapor barriers are built with multiple layers or mesh-like reinforcement for added strength. These are ideal for mobile homes in humid climates like Largo, FL, where moisture is a constant threat. They offer longer-lasting performance and are less likely to tear or shift over time, making them a popular choice for crawl spaces.
Vapor Barrier Underlayment
Vapor barrier underlayment is designed for use under flooring like laminate, vinyl, or hardwood. While not for crawl spaces, it adds another layer of moisture protection inside the home. It helps prevent moisture damage to floors while improving insulation and comfort, perfect for mobile homes undergoing interior upgrades or renovations.
Other Materials (Foils, Coatings, etc.)
Some vapor barriers use aluminum foil, foam panels, or liquid-applied coatings for niche applications. These are typically used in walls or specialized insulation systems, not under mobile homes. While they offer unique benefits in certain situations, they are less common for crawl space moisture control and are usually more expensive.
Vapor Barrier Thickness: How Thick Should It Be?
Vapor barrier thickness is measured in mils, with one mil equal to one-thousandth of an inch. The thicker the barrier, the more durable and resistant it is to tears, punctures, and long-term wear, especially in high-moisture environments like mobile home crawl spaces.
A 6 mil vapor barrier is a budget-friendly option often used for short-term or light-duty protection, but it can tear easily and may not hold up well in humid climates like Largo, FL. A 10 mil vapor barrier offers a stronger layer and is commonly chosen for mobile home applications that need a balance between affordability and durability. For maximum protection, a 20 mil vapor barrier is the most robust choice. It’s tear-resistant, long-lasting, and ideal for crawl spaces that require heavy-duty moisture control.
How to Install Vapor Barrier in a Crawl Space or Mobile Home
Basic Steps for Installation
Installing a vapor barrier starts with clearing debris, leveling the crawl space, and ensuring a dry surface. Once prepped, the barrier is laid out smoothly, seams are overlapped and sealed with tape, and edges are secured to prevent movement. While it might seem like a DIY-friendly task, mistakes in placement or sealing can lead to moisture buildup, mold, and wasted effort. That’s why it’s best to hire a professional who can do the job right the first time.

Finally, local labor rates in Largo, FL can impact costs, especially when hiring experienced professionals who ensure a secure and lasting installation.
