The Ultimate Guide to Crawl Space Encapsulation Green Frog Tuesday, September 27, 2022

Be honest with yourself: when was the last time you gave any thought to your crawl space? If it’s been a while, you’re not alone! Homeowners tend to ignore their crawl space until issues arise that can sometimes cost thousands of dollars to fix. Fortunately, crawl space encapsulation can help eliminate these common moisture problems, keeping your home safe from damage. 

What is crawl space encapsulation, exactly? And why should you consider it for your home? We’ve got all the answers you need. Dive into this detailed guide to learn everything you need to know!

What Is Crawl Space Encapsulation?

In the simplest terms, crawl space encapsulation involves adding a heavy-duty plastic vapor barrier to the floor and walls of your crawl space to keep moisture out. In some cases, you may also opt to install a dehumidifier to further control moisture levels in the space. 

The length of the project largely depends on the size of your crawl space but in most cases, we can complete the job in just a few days.

What Happens During the Encapsulation Process?

Before you decide to schedule an encapsulation for yourself, it helps to understand what you can expect during the process. 


When you hire the Green Frog Waterproofing team, we’ll come out to your home and clear out your crawl space. This is when we’ll remove dirt and debris and check your existing insulation for damage. If there’s any existing water damage in the area, we’ll resolve it before moving forward.


Next, we’ll install the vapor barrier, which will cover the walls and floor of your crawl space. This polyethylene material is not only waterproof, but it also helps improve the air quality in your home and keeps out rodents and other critters. Once we lay out the barrier, we’ll secure it with double-sided tape. 


The final step involves cutting the barrier around any obstacles, like pillars. If there are any gaps, we’ll fill them with foam spray or additional sealing tape. Once we’re finished sealing the area, we may make extra recommendations, such as adding a dehumidifier to the space.

What Are the Benefits of Crawl Space Encapsulation?

So, do you really need to encapsulate your crawl space? Here are a few benefits to consider when making your decision. 

Your Home Will Be More Comfortable

With a vented crawl space, your home will feel hotter in the summer and colder in the winter. By encapsulating the space, external weather conditions won’t have as much of an effect on your indoor temperature. 

Your Electricity Bills May Decrease

Along those same lines, you may notice lower utility bills after your encapsulation. Your heating and cooling system won’t have to work as hard to keep your home comfortable to compensate for fluctuating temperatures caused by your crawl space, helping to reduce your bill. 

You Won’t Find as Many Pests in Your Home

Finding creepy crawlies in your home is always an unsettling experience. They’re naturally drawn to wet, dark spaces, which is why they come into your crawl space. Since encapsulation removes moisture, fewer pests will make their way to your home. 

You Won’t Have to Worry About Mold

Much like pests, mold needs damp spaces to thrive. By encapsulating your crawl space, mold won’t be able to grow and you won’t have to worry about the respiratory issues that often plague families with a moldy crawl space. 

Your Home Will Be More Structurally Sound

The wet soil in a crawl space can weaken your home’s foundation over time. When you encapsulate the space, the soil around your foundation will stay dry, which aids in the structural integrity of your home.
