There are several different elements of crawl space encapsulation, with one of the more important elements being the crawl space vapor barrier. This barrier is made of plastic, and it is laid across the dirt floor of your crawl space, ensuring pests and excess moisture don’t creep in to make your crawl space their home.

How Our Product Works

  1. At Peak Structural, we utilize a 20-mil-thick vapor barrier that is specially designed to keep your crawl space dry and free of water. We don’t recommend you attempt any repairs or even enter your crawl space. That should be left to professionals as the vapor barrier forms a seal to keep out the elements, pests, and debris. 
  2. Technicians will check that your crawl space is free of debris before the installation begins. They will then lay out the plastic barrier, ensuring that it is the correct size for your home’s crawl space and that all openings are covered. Using special adhesive, the barrier is then held down.
  3. Finally, technicians will add moisture-proof insulation to ensure your crawl space is properly encapsulated or waterproofed. Once your vapor barrier is installed, you can continue the process of encapsulating your crawl space, keeping your home and crawl space a more regulated area when it comes to temperature and moisture.

Why Our Product is Better Than the Competitors

  • Moisture-preventing: Our vapor barrier is exceptional at keeping moisture – and even pests – from getting inside your crawl space. This ensures that the humidity levels in your crawl space – and home – will remain stable and comfortable.
