Why Plastic for Crawl Space is Necessary

As a homeowner, I quickly learned that maintaining a healthy crawl space is crucial for the overall integrity of my house. One of the most significant improvements I made was installing a plastic vapor barrier. It might seem like a simple step, but the benefits are profound.

First and foremost, using plastic in my crawl space has been essential for controlling moisture. Living in an area with high humidity, I noticed how quickly dampness could seep in. The plastic barrier effectively blocks moisture from the ground, preventing mold and mildew from taking hold. Since installing it, I’ve seen a significant reduction in musty odors and a much healthier environment below my home.

Additionally, the plastic barrier has helped improve energy efficiency. By reducing moisture and regulating temperature, my HVAC system doesn’t have to work as hard. I’ve noticed a drop in my energy bills since I took this step, which is always a welcome change.

Lastly, the plastic serves as an additional layer of protection against pests. Before installation, I often found signs of rodents and insects in the crawl space. The plastic creates a less inviting environment for these unwanted guests. Overall, my experience with using plastic in the crawl space has been overwhelmingly positive, leading to a

My Buying Guides on Plastic For Crawl Space

When I decided to tackle the issue of my crawl space, I knew that selecting the right plastic was crucial for creating a clean, safe, and moisture-resistant environment. Here’s a comprehensive buying guide based on my experience that will help you make an informed decision when purchasing plastic for your crawl space.

Understanding the Purpose of Crawl Space Plastic

Before I made my purchase, I took some time to understand why plastic is essential for crawl spaces. The primary functions include:

  • Moisture Barrier: Plastic sheeting helps prevent moisture from the ground from seeping into the crawl space, which is critical for avoiding mold and mildew.
  • Pest Control: A good plastic barrier can deter pests from entering your home through the crawl space.
  • Insulation: It can contribute to better insulation, improving energy efficiency in your home.

Types of Plastic Sheeting

I found that there are several types of plastic sheeting available, each with its pros and cons:

  • Polyethylene: This is the most common type used for crawl spaces. It’s durable, affordable, and comes in various thicknesses. I opted for a thicker option for added durability.
  • Vapor Barriers: These are specifically designed to block moisture. They often have a higher perm rating and are essential if you live in a high-moisture area.
  • Reinforced Plastic: For those who are concerned about durability, reinforced plastic offers extra strength and resistance against tears.

Thickness Matters

One of the key factors I considered was the thickness of the plastic sheeting. It typically ranges from 6 mil to 20 mil. Here’s how I approached it:

  • 6 mil: Suitable for light-duty applications but not ideal for crawl spaces with high moisture or potential damage.
  • 10 mil: A good choice for most crawl spaces; it’s sturdy and provides a decent moisture barrier.
  • 15-20 mil: This is what I went with for my project. The extra thickness provides a robust barrier and better longevity.

Choosing the Right Size

When I measured my crawl space, I made sure to account for the following:

  • Length and Width: Measure the entire area to ensure you purchase enough plastic. I added a little extra to allow for overlaps and seams.
  • Height: If my crawl space was particularly tall, I considered the height when determining how much plastic I would need.

Installation Considerations

Having installed the plastic myself, I learned a few things about installation:

  • Seams and Overlaps: I made sure to overlap the seams by at least 12 inches and sealed them with tape. This step is vital to prevent moisture from seeping through.
  • Anchor the Edges: I used rocks or treated wood to weigh down the edges of the plastic, ensuring it stayed in place.

Where to Buy

I found several places to purchase crawl space plastic:

  • Home Improvement Stores: Stores like Home Depot or Lowe’s offer a variety of options, and I appreciated being able to see the products in person.
  • Online Retailers: Websites like Amazon or specialized home improvement sites often have a broader selection, and I found competitive prices.
  • Local Suppliers: I also checked with local building supply companies, which sometimes offer better deals or bulk options.

Final Thoughts

Choosing the right plastic for my crawl space was a significant decision that positively impacted my home’s overall health. I encourage you to take your time, measure carefully, and consider your specific needs. With the right plastic sheeting, you can create a dry, pest-free environment in your crawl space, just like I did!
