Why Plastic for Crawl Space Is Necessary
From my experience, using plastic in the crawl space is absolutely essential for maintaining a healthy and safe home environment. The main reason I rely on plastic sheeting is to act as a vapor barrier. Crawl spaces are naturally prone to moisture buildup from the ground, and without a proper barrier, that moisture seeps into the wood and insulation, causing mold, mildew, and even structural damage over time.
I’ve noticed that once I installed plastic sheeting, the air quality in my home improved significantly. The plastic prevents dampness from rising into the living areas, which helps reduce musty odors and protects my family from potential respiratory issues. Additionally, the plastic barrier keeps pests like termites and rodents at bay, since they are less attracted to a dry, sealed environment.
Overall, using plastic in the crawl space has saved me from costly repairs and given me peace of mind. It’s a simple step that makes a huge difference in preserving the integrity and comfort of my home.
My Buying Guides on Plastic For Crawl Space
When I first started looking for plastic to use in my crawl space, I quickly realized there are a few important factors to consider to get the right product. Over time, I’ve learned what works best and what to avoid. Here’s my guide to help you choose the perfect plastic for your crawl space.
Why Use Plastic in Your Crawl Space?
From my experience, using plastic sheeting in the crawl space is essential to control moisture, prevent mold, and improve air quality in your home. It acts as a vapor barrier, stopping dampness from the ground from seeping into the space above. This can also help with energy efficiency by keeping the crawl space dry and insulated.
Choosing the Right Thickness
One of the first things I noticed is that thickness really matters. Plastic sheeting for crawl spaces typically comes in 6 mil, 10 mil, 12 mil, or even thicker. I found that:
- 6 mil is the thinnest and most affordable but can tear easily.
- 10 mil is a popular balance between durability and cost.
- 12 mil or thicker offers better puncture resistance and longevity, which is ideal if your crawl space has rough surfaces or potential debris.
I personally went with 12 mil because I wanted something that would last without needing replacement anytime soon.
Material Type and Quality
Most crawl space plastics are made from polyethylene. I made sure to pick a heavy-duty polyethylene that was labeled as “crawl space vapor barrier” or “encapsulation plastic.” Some brands add UV inhibitors and anti-microbial properties to resist mold growth, which I found very helpful in a damp environment. Avoid cheap plastics that might degrade quickly or allow moisture through.
Size and Coverage
Before buying, I measured my crawl space carefully. The plastic comes in various widths and lengths, so I chose a roll that would cover the entire area with some overlap on the edges for sealing. It’s better to have a little extra than to run short in the middle of installation. Also, look for plastic that is wide enough to cover large sections without too many seams.
Installation Features
I looked for plastic with features that would make installation easier, such as:
- Pre-scored edges for easier cutting
- Tear-resistant qualities
- Compatibility with crawl space tape or adhesive for sealing seams tightly
Some plastics come with a textured surface to reduce slipping, which I found helpful when working in tight spaces.
Cost vs. Durability
In my experience, spending a bit more upfront on higher-quality plastic pays off in the long run. Cheaper plastic may save money initially but can tear, degrade, or allow moisture through, causing bigger problems later. I recommend balancing cost with durability, leaning toward quality for peace of mind.
Additional Tips from My Experience
- Always clean and level the crawl space floor before laying down plastic to avoid punctures.
- Overlap seams by at least 12 inches and seal them with crawl space tape.
- Consider adding foam board insulation over the plastic for extra energy efficiency.
- Check local building codes or consult a professional if you’re unsure about vapor barrier requirements.

I hope my buying guide helps you find the best plastic for your crawl space. Taking the time to choose quality material and install it properly can make a huge difference in protecting your home from moisture and improving indoor air quality.
