When it comes to keeping your crawl space free of outside air and moisture, crawl space encapsulation is the best choice. With crawl space encapsulation, you can improve the health of your home, as well as its crawl space. At Peak Structural, our team has the skills and equipment to effectively waterproof – or encapsulate – your crawl space.

How Crawl Space Encapsulation Works

There isn’t just one aspect of crawl space encapsulation, there are multiple elements that need to be combined in order to completely encapsulate your crawl space. When it comes to crawl space encapsulation, these are the steps our technicians will follow:

  • The first step of crawl space encapsulation involves adding a layer of plastic – known as the vapor barrier – and removing unnecessary crawl space vents that will let in external air and moisture. At Peak, we utilize a 20-mil-thick vapor barrier, ensuring there are no rips or tears.
  • Next, you’ll want to add both insulation and drainage to the crawl space. Insulation will help maintain both moisture and temperature levels, helping you save on electric bills. If your crawl space has excess crawl space vents, these may be removed to prevent excess moisture from gathering inside the crawl space.
  • Finally, if you want more moisture control inside your crawl space, then investing in a quality dehumidifier is one of the best options. Adding a crawl space dehumidifier helps control moisture levels, ensuring that the levels never reach a point where the moisture begins to negatively affect the conditions in your crawl space.

Why Choose Us Over Other Crawl Space Repair Companies?

  • Lower Utility Bills: When your crawl space is sealed off from outside moisture and air, then the moisture and temperature levels in your home will be more comfortable and stable, effectively lowering your electricity bills. 
  • Less Allergy and Asthma Symptoms: Because your crawl space is sealed off from outside air, you and others in your home are less likely to suffer from symptoms of allergies and asthma. Less pollen will get into your encapsulated crawl space, so you can breathe easy. 
  • Mold Control: Just like pollen, mold can easily get into a crawl space that has not been encapsulated. Mold is attracted to moisture and darkness, making your crawl space prime real-estate from mold and mildew.

Signs Your Home Needs Crawl Space Encapsulation

Sagging Floor

If you notice that your floors are sagging or sloping in certain places, then you most likely have a problem in your crawl space, especially if it is not encapsulated. When water gets into your crawl space, it can cause wood rot that will start to eat away at the wooden structures – like structural supports – that will deteriorate and weaken.

Standing Water in the Crawl Space

If your crawl space is not sealed off from outside moisture, water can easily get inside where it will gather in pools. To check for standing water, simply shine a light into your crawl space to check. Another sign of standing water is excess humidity in the home.

Defective Vapor Barrier

When your vapor barrier starts to fail, then your entire encapsulation system will also begin to falter. If you’re dealing with a crawl space vapor barrier that is ineffective, you’ll most likely experience excess moisture, mold, and higher electricity bills.


We do not recommend going directly into your crawl space on your own, even if you have an easily accessible crawl space. There can be unseen debris and creatures – such as snakes and lizards – that could be harmful to run into. This is why it is so important to hire a professional that understands crawl space encapsulation.

No, practically any type of crawl space can be effectively encapsulated and sealed off from external air and moisture. While it is extremely effective for crawl spaces with dirt floors, it can also greatly benefit crawl spaces with other types of floors. 

Yes, encapsulated crawl spaces can help reduce mold by controlling the amount of moisture in the space. This means less mold growth, which then means you and your family are not exposed to excessive amounts of mold coming from your home’s crawl space.
