CRAWL SPACE ENCAPSULATION

Crawl space encapsulation is a term we often use as a crawl space contractor, but homeowners may/may not understand the meaning. More less, crawl space encapsulation refers to the process of protecting the crawl space from moisture, mold and odors.

 

While you may hear terms used other than encapsulated crawl space, nearly all of them likely refer to the same thing, protecting the crawl space.

 

There’s a number of crawl space encapsulation supplies you’ll need to get the job done, but in this article, we’re only referring to the actual products you’ll need to become familiar with. The first term is a crawl space vapor barrier, also referred to as a crawl space liner or crawl space plastic.

CRAWL SPACE VAPOR BARRIERS COME IN A VARIETY OF DIFFERENT SIZES.

Crawl space vapor barriers come in a variety of different sizes. The crawl space liner size you use depends on the crawl space itself. The 20 mil crawl space vapor barrier and the 12 mil crawl space vapor barrier are two of the most common sizes used for encapsulating a crawl space.

12 MIL CRAWL SPACE VAPOR BARRIER

The 12 mil crawl space liner is most commonly used to cover the foundation walls of the crawl space. You can use a 12 mil vapor barrier for your crawl space floor also. The 12 mil crawl space liner is recommended for medium storage and medium traffic on the vapor barrier.

20 MIL CRAWL SPACE VAPOR BARRIER

The 20 mil crawl space liner is used for crawl spaces that may have sharp rocks or objects in the crawl space floor. The 20 mil is thicker than the 12 mil, as well as other vapor barrier sizes such as the 6 mil and 8 mil crawl space liners. If you’ll have heavy traffic on the crawl space or will be storing heavy objects on the crawl space, the 20 mil vapor barrier is recommended.

WHY CRAWL SPACE ENCAPSULATION?

The main reason for crawl space encapsulation is to control the environment of the crawl space. When you typically think of a crawl space, you often think “dirty,” “moist,” “musky” or “smelly.” For open crawl spaces, this is often true. Why? Simply put, it’s acceptable to the environment. With a sealed crawl space, environmental conditions are kept out.

While we don’t think about it enough, not maintaining the crawl space can cause a host of trouble you do not want.

Mold

One of the biggest fears in the crawl space is mold. Black mold can kill you and the crawl space is a perfect breeding ground for it.

Moisture and Water

Moisture and water can eat through the foundation of your home, leaving your home damaged and sometimes unable to be fixed.

Radon Gas

Radon gas is another big concern in the crawl space.

WHAT SHOULD I DO?

Sure, I’m a crawl space contractor. Do I want you to give me a call to fix your crawl space? Absolutely, but if your crawl space is not encapsulated, get it done. The great thing about crawl space encapsulation is the fact that you can learn to do it. Then you don’t need a contractor. There’s a lot of great resources out there to help you learn DIY crawl space repair. If you can’t afford to have it professionally done, learn how to do it yourself.

While you may hear terms used other than encapsulated crawl space, nearly all of them likely refer to the same thing, protecting the crawl space. With the right materials to encapsulate your crawl space, any DIY homeowner can learn how to properly seal the crawl space.

THE COST OF ENCAPSULATING YOUR CRAWL SPACE

Let’s talk about the cost of encapsulating your crawl space. For starters, no crawl space encapsulation project is the same. The crawl space encapsulation supplies you’ll need will be determined by the size of your crawl space and the uses of your crawl space.

Do you use your crawl space floor for storage? Do you commonly walk across your crawl space. If you said yes to both, you may want to consider a larger sized vapor barrier on the floor. If you won’t be storing or walking on the crawl space liner, a smaller size may do the job.

What I know you’ll need to encapsulate the crawl space is crawl space vapor barrier, crawl space tape and likely a crawl space dehumidifier if you want to completely remove the moisture in your crawl space. If you don’t have the right tools, you can expect to pay more. It’s tough to estimate an actual cost, but you could be looking at paying a few thousand dollars to say the least. 

If you need a more accurate number, measure your crawl space dimensions and contact an expert. If you encapsulate the crawl space yourself, you will save money. If you hire a contractor, expect to pay a few thousand more.
